SSM（Spring+SpringMVC+MyBatis）框架集由Spring、MyBatis兩個(gè)開源框架整合而成（SpringMVC是Spring中的部分內(nèi)容），常作為數(shù)據(jù)源較簡(jiǎn)單的web項(xiàng)目的框架。

環(huán)境：

• IDEA
• MySQL 5.7.19
• Tomcat 9
• Maven 3.6

要求：
需要熟練掌握MySQL數(shù)據(jù)庫(kù)，Spring，JavaWeb及MyBatis知識(shí)，簡(jiǎn)單的前端知識(shí)

1. 數(shù)據(jù)庫(kù)環(huán)境

創(chuàng)建一個(gè)存放書籍?dāng)?shù)據(jù)的數(shù)據(jù)庫(kù)表

CREATE DATABASE `ssmbuild`;USE `ssmbuild`;DROP TABLE IF EXISTS `books`;CREATE TABLE `books` (`bookID` INT(10) NOT NULL AUTO_INCREMENT COMMENT '書id',`bookName` VARCHAR(100) NOT NULL COMMENT '書名',`bookCounts` INT(11) NOT NULL COMMENT '數(shù)量',`detail` VARCHAR(200) NOT NULL COMMENT '描述',KEY `bookID` (`bookID`) ) ENGINE=INNODB DEFAULT CHARSET=utf8INSERT INTO `books`(`bookID`,`bookName`,`bookCounts`,`detail`)VALUES (1,'Java',1,'從入門到放棄'), (2,'MySQL',10,'從刪庫(kù)到跑路'), (3,'Linux',5,'從進(jìn)門到進(jìn)牢');

2. 項(xiàng)目基本結(jié)構(gòu)搭建

1、新建一Maven項(xiàng)目，命名為 ssmbuild

2、在pom.xml文件中導(dǎo)入相關(guān)的pom依賴

<dependencies><!--Junit--><dependency><groupId>junit</groupId><artifactId>junit</artifactId><version>4.12</version></dependency><!--數(shù)據(jù)庫(kù)驅(qū)動(dòng)--><dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId><version>5.1.47</version></dependency><!-- 數(shù)據(jù)庫(kù)連接池 --><dependency><groupId>com.mchange</groupId><artifactId>c3p0</artifactId><version>0.9.5.2</version></dependency><!--Servlet - JSP --><dependency><groupId>javax.servlet</groupId><artifactId>servlet-api</artifactId><version>2.5</version></dependency><dependency><groupId>javax.servlet.jsp</groupId><artifactId>jsp-api</artifactId><version>2.2</version></dependency><dependency><groupId>javax.servlet</groupId><artifactId>jstl</artifactId><version>1.2</version></dependency><!--Mybatis--><dependency><groupId>org.mybatis</groupId><artifactId>mybatis</artifactId><version>3.5.2</version></dependency><dependency><groupId>org.mybatis</groupId><artifactId>mybatis-spring</artifactId><version>2.0.2</version></dependency><!--Spring--><dependency><groupId>org.springframework</groupId><artifactId>spring-webmvc</artifactId><version>5.1.9.RELEASE</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-jdbc</artifactId><version>5.1.9.RELEASE</version></dependency><!-- lombok --><dependency><groupId>org.projectlombok</groupId><artifactId>lombok</artifactId><version>1.18.10</version></dependency></dependencies>

3、同時(shí)在pom.xml文件中的依賴底下添加Maven資源過(guò)濾設(shè)置

<build><resources><resource><directory>src/main/java</directory><includes><include>**/*.properties</include><include>**/*.xml</include></includes><filtering>false</filtering></resource><resource><directory>src/main/resources</directory><includes><include>**/*.properties</include><include>**/*.xml</include></includes><filtering>false</filtering></resource></resources></build>

4、建立基本結(jié)構(gòu)和配置框架

（1）在java包下創(chuàng)建如下目錄層級(jí)：

• com.zz.pojo 實(shí)體層
• com.zz.mapper 接口層
• com.zz.service 服務(wù)層
• com.zz.controller 控制層

（2）在resources包下創(chuàng)建如下配置文件：

• mybatis-config.xml

<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE configurationPUBLIC "-//mybatis.org//DTD Config 3.0//EN""http://mybatis.org/dtd/mybatis-3-config.dtd"> <configuration></configuration>

• applicationContext.xml

<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans.xsd"></beans>

• springmvc-servlet.xml

<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans.xsd"></beans>

3. 配置MyBatis

1、在resources目錄下創(chuàng)建數(shù)據(jù)庫(kù)配置文件 database.properties

jdbc.driver=com.mysql.jdbc.Driver jdbc.url=jdbc:mysql://localhost:3306/ssmbuild?useSSL=true&useUnicode=true&characterEncoding=utf8 jdbc.username=root jdbc.password=123456

2、 IDEA關(guān)聯(lián)數(shù)據(jù)庫(kù)

3、編寫MyBatis的核心配置文件 mybatis-config.xml

<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE configurationPUBLIC "-//mybatis.org//DTD Config 3.0//EN""http://mybatis.org/dtd/mybatis-3-config.dtd"> <configuration><!--設(shè)置,可根據(jù)需要配置日志--><!--<settings>--><!--<setting name="logImpl" value="STDOUT_LOGGING"/>--><!--</settings>--><!--別名--><typeAliases><package name="com.zz.pojo"/></typeAliases></configuration>

4、編寫數(shù)據(jù)庫(kù)對(duì)應(yīng)的實(shí)體類 com.zz.pojo.Books
使用lombok插件

package com.zz.pojo;import lombok.AllArgsConstructor; import lombok.Data; import lombok.NoArgsConstructor;@Data @AllArgsConstructor @NoArgsConstructor public class Books {private int bookID;private String bookName;private int bookCounts;private String detail;}

5、編寫接口層的接口 com.zz.mapper.BookMapper

package com.zz.mapper;import com.zz.pojo.Books; import java.util.List;public interface BookMapper {//增加一個(gè)Bookint addBook(Books book);//根據(jù)id刪除一個(gè)Bookint deleteBookById(int id);//更新Bookint updateBook(Books books);//根據(jù)id查詢,返回一個(gè)BookBooks queryBookById(int id);//查詢?nèi)緽ook,返回list集合List<Books> queryAllBook();// 根據(jù)書名查詢數(shù)據(jù)Books queryBooksByName(String bookName);}

6、編寫接口對(duì)應(yīng)的配置文件 com.zz.mapper.BookMapper.xml
需要導(dǎo)入MyBatis的包

<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE mapperPUBLIC "-//mybatis.org//DTD Mapper 3.0//EN""http://mybatis.org/dtd/mybatis-3-mapper.dtd"><mapper namespace="com.zz.mapper.BookMapper"><!--增加一個(gè)Book--><insert id="addBook" parameterType="Books">insert into ssmbuild.books(bookName,bookCounts,detail)values (#{bookName}, #{bookCounts}, #{detail})</insert><!--根據(jù)id刪除一個(gè)Book--><delete id="deleteBookById" parameterType="int">delete from ssmbuild.books where bookID=#{bookID}</delete><!--更新Book--><update id="updateBook" parameterType="Books">update ssmbuild.booksset bookName = #{bookName},bookCounts = #{bookCounts},detail = #{detail}where bookID = #{bookID}</update><!--根據(jù)id查詢,返回一個(gè)Book--><select id="queryBookById" resultType="Books">select * from ssmbuild.bookswhere bookID = #{bookID}</select><!--查詢?nèi)緽ook--><select id="queryAllBook" resultType="Books">SELECT * from ssmbuild.books</select><!--根據(jù)書名查詢數(shù)據(jù)--><select id="queryBooksByName" resultType="Books">select * from ssmbuild.books where bookName = #{bookName}</select></mapper>

7、編寫Service層的接口 com.zz.service.BookService

package com.zz.service;import com.zz.pojo.Books;import java.util.List;//BookService:底下需要去實(shí)現(xiàn),調(diào)用dao層 public interface BookService {//增加一個(gè)Bookint addBook(Books book);//根據(jù)id刪除一個(gè)Bookint deleteBookById(int id);//更新Bookint updateBook(Books books);//根據(jù)id查詢,返回一個(gè)BookBooks queryBookById(int id);//查詢?nèi)緽ook,返回list集合List<Books> queryAllBook();// 根據(jù)書名查詢數(shù)據(jù)Books queryBooksByName(String bookName);}

8、編寫Service層的實(shí)現(xiàn)類 com.zz.service.BookServiceImpl

package com.zz.service;import com.zz.mapper.BookMapper; import com.zz.pojo.Books; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Service;import java.util.List; // mvc // @Service public class BookServiceImpl implements BookService {//調(diào)用dao層的操作，設(shè)置一個(gè)set接口，方便Spring管理// @Autowiredprivate BookMapper bookMapper;public void setBookMapper(BookMapper bookMapper) {this.bookMapper = bookMapper;}public int addBook(Books book) {return bookMapper.addBook(book);}public int deleteBookById(int id) {return bookMapper.deleteBookById(id);}public int updateBook(Books books) {return bookMapper.updateBook(books);}public Books queryBookById(int id) {return bookMapper.queryBookById(id);}public List<Books> queryAllBook() {return bookMapper.queryAllBook();}public Books queryBooksByName(String bookName) {return bookMapper.queryBooksByName(bookName);} }

OK，至此，底層需求操作編寫完畢！

4. 配置Spring

1、配置Spring整合MyBatis，我們這里數(shù)據(jù)源使用c3p0連接池；
2、我們?nèi)ゾ帉慡pring整合Mybatis和整合service層相關(guān)的配置文件； applicationContext.xml

<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans"xmlns:context="http://www.springframework.org/schema/context"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans.xsdhttp://www.springframework.org/schema/contexthttp://www.springframework.org/schema/context/spring-context.xsd"><import resource="classpath:springmvc-servlet.xml"/><!-- 配置整合mybatis --><!-- 1.關(guān)聯(lián)數(shù)據(jù)庫(kù)文件 --><context:property-placeholder location="classpath:database.properties"/><!-- 2.數(shù)據(jù)庫(kù)連接池 --><!--數(shù)據(jù)庫(kù)連接池dbcp 半自動(dòng)化操作 不能自動(dòng)連接c3p0 自動(dòng)化操作（自動(dòng)的加載配置文件 并且設(shè)置到對(duì)象里面）spring-jdbc--><bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"><!-- 配置連接池屬性 --><property name="driverClass" value="${jdbc.driver}"/><property name="jdbcUrl" value="${jdbc.url}"/><property name="user" value="${jdbc.username}"/><property name="password" value="${jdbc.password}"/><!-- c3p0連接池的私有屬性 --><property name="maxPoolSize" value="30"/><property name="minPoolSize" value="10"/><!-- 關(guān)閉連接后不自動(dòng)commit --><property name="autoCommitOnClose" value="false"/><!-- 獲取連接超時(shí)時(shí)間 --><property name="checkoutTimeout" value="10000"/><!-- 當(dāng)獲取連接失敗重試次數(shù) --><property name="acquireRetryAttempts" value="2"/></bean><!-- 3.配置SqlSessionFactory對(duì)象 --><bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"><!-- 注入數(shù)據(jù)庫(kù)連接池 --><property name="dataSource" ref="dataSource"/><!-- 配置MyBatis全局配置文件:mybatis-config.xml --><property name="configLocation" value="classpath:mybatis-config.xml"/><property name="mapperLocations" value="classpath:com/zz/mapper/*.xml"/></bean><!-- 4.配置掃描Dao接口包，動(dòng)態(tài)實(shí)現(xiàn)Dao接口注入到spring容器中 --><!--解釋 ： https://www.cnblogs.com/jpfss/p/7799806.html--><bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"><!-- 注入sqlSessionFactory --><property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/><!-- 給出需要掃描Dao接口包 --><property name="basePackage" value="com.zz.mapper"/></bean><!-- 以下是整合Service --><!-- 綁定并掃描Service，增加事務(wù)的支持 --><!-- 掃描service相關(guān)的bean --><context:component-scan base-package="com.zz.service" /><!--BookServiceImpl注入到IOC容器中--><bean id="BookServiceImpl" class="com.zz.service.BookServiceImpl"><property name="bookMapper" ref="bookMapper"/></bean><!-- 配置事務(wù)管理器 --><bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"><!-- 注入數(shù)據(jù)庫(kù)連接池 --><property name="dataSource" ref="dataSource" /></bean></beans>

至此，Spring層搞定！可以看出，Spring就是一個(gè)大雜燴，一個(gè)容器！

5. 配置SpringMVC

給項(xiàng)目添加web框架的支持，從一個(gè)Spring項(xiàng)目變成一個(gè)web項(xiàng)目

1、web.xml 文件

<?xml version="1.0" encoding="UTF-8"?> <web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd"version="4.0"><!--DispatcherServlet--><servlet><servlet-name>DispatcherServlet</servlet-name><servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class><init-param><param-name>contextConfigLocation</param-name><param-value>classpath:applicationContext.xml</param-value></init-param><load-on-startup>1</load-on-startup></servlet><servlet-mapping><servlet-name>DispatcherServlet</servlet-name><url-pattern>/</url-pattern></servlet-mapping><!--encodingFilter--><filter><filter-name>encodingFilter</filter-name><filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class><init-param><param-name>encoding</param-name><param-value>utf-8</param-value></init-param></filter><filter-mapping><filter-name>encodingFilter</filter-name><url-pattern>/*</url-pattern></filter-mapping><!--&lt;!&ndash;Session過(guò)期時(shí)間,可根據(jù)需求自行添加&ndash;&gt;--><!--<session-config>--><!--<session-timeout>15</session-timeout>--><!--</session-config>--></web-app>

2、springmvc-servlet.xml文件

<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans"xmlns:mvc="http://www.springframework.org/schema/mvc"xmlns:context="http://www.springframework.org/schema/context"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans.xsdhttp://www.springframework.org/schema/mvchttp://www.springframework.org/schema/mvc/spring-mvc.xsdhttp://www.springframework.org/schema/contexthttp://www.springframework.org/schema/context/spring-context.xsd"><!-- 配置SpringMVC --><!-- 1.開啟SpringMVC注解驅(qū)動(dòng) --><mvc:annotation-driven /><!-- 2.靜態(tài)資源默認(rèn)servlet配置--><mvc:default-servlet-handler/><!-- 3.配置jsp 顯示ViewResolver視圖解析器 --><bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"><property name="viewClass" value="org.springframework.web.servlet.view.JstlView" /><property name="prefix" value="/WEB-INF/jsp/" /><property name="suffix" value=".jsp" /></bean><!-- 4.掃描web相關(guān)的bean --><context:component-scan base-package="com.zz.controller" /></beans>

注意：若此時(shí)發(fā)現(xiàn)applicationContext.xml文件中bookMapper處報(bào)紅，則檢查以下之處，保證根目錄只有一個(gè)，刪除底下那個(gè)即可！

3、Spring配置整合文件，在applicationContext.xml中導(dǎo)入springmvc-servlet.xml配置文件

<!--引入springmvc-servlet.xml，因?yàn)閣eb.xml中關(guān)聯(lián)的是applicationContext.xml--> <import resource="classpath:springmvc-servlet.xml"/>

至此，配置文件暫時(shí)結(jié)束！

此時(shí)的項(xiàng)目目錄：

6. Controller和視圖層編寫

方法一：查詢?nèi)繒?/strong>
1、BookController 類編寫 com.zz.controller.BookController

@Controller @RequestMapping("/book") public class BookController {@Autowired@Qualifier("BookServiceImpl")private BookService bookService;@RequestMapping("/allBook")public String list(Model model) {List<Books> list = bookService.queryAllBook();model.addAttribute("list", list);return "allBook";} }

2、編寫首頁(yè) index.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8" %> <!DOCTYPE HTML> <html> <head><title>首頁(yè)</title><style type="text/css">a {text-decoration: none;color: black;font-size: 18px;}h3 {width: 180px;height: 38px;margin: 100px auto;text-align: center;line-height: 38px;background: deepskyblue;border-radius: 4px;}</style> </head> <body><h3><a href="${pageContext.request.contextPath}/book/allBook">點(diǎn)擊進(jìn)入列表頁(yè)</a> </h3> </body> </html>

3、書籍列表頁(yè)面 WEB-INF.jsp.allbook.jsp

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %> <%@ page contentType="text/html;charset=UTF-8" language="java" %> <html> <head><title>書籍列表</title><meta name="viewport" content="width=device-width, initial-scale=1.0"><!-- 引入 Bootstrap --><link href="https://cdn.bootcss.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet"> </head> <body><div class="container"><div class="row clearfix"><div class="col-md-12 column"><div class="page-header"><h1><small>書籍列表 —— 顯示所有書籍</small></h1></div></div></div><div class="row"><div class="col-md-4 column"><a class="btn btn-primary" href="${pageContext.request.contextPath}/book/toAddBook">新增</a><a class="btn btn-primary" href="${pageContext.request.contextPath}/book/allBook">顯示全部書籍</a></div><div class="col-md-4 column"><span style="color: red;font-weight: bold">${error}</span></div><div class="col-md-4 column"><form action="/book/queryBook" method="post" class="form-inline"><input type="text" name="queryBookName" class="form-control" placeholder="請(qǐng)輸入要查詢的書名" required><input type="submit" value="查詢" class="btn btn-success"></form></div></div><div class="row clearfix"><div class="col-md-12 column"><table class="table table-hover table-striped"><thead><tr><th>書籍編號(hào)</th><th>書籍名字</th><th>書籍?dāng)?shù)量</th><th>書籍詳情</th><th>操作</th></tr></thead><tbody><c:forEach var="book" items="${requestScope.get('list')}"><tr><td>${book.getBookID()}</td><td>${book.getBookName()}</td><td>${book.getBookCounts()}</td><td>${book.getDetail()}</td><td><a href="${pageContext.request.contextPath}/book/toUpdateBook?id=${book.getBookID()}">更改</a> |<a href="${pageContext.request.contextPath}/book/del/${book.getBookID()}">刪除</a></td></tr></c:forEach></tbody></table></div></div> </div>

方法二：添加書籍
4、BookController 類編寫

//先跳轉(zhuǎn)到添加書籍頁(yè)面，再添加書籍跳轉(zhuǎn)到首頁(yè)@RequestMapping("/toAddBook")public String toAddPaper() {return "addBook";}@RequestMapping("/addBook")public String addPaper(Books books) {System.out.println(books);bookService.addBook(books);return "redirect:/book/allBook";}

5、添加書籍頁(yè)面： WEB-INF.jsp.addBook.jsp

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %> <%@ page contentType="text/html;charset=UTF-8" language="java" %><html> <head><title>新增書籍</title><meta name="viewport" content="width=device-width, initial-scale=1.0"><!-- 引入 Bootstrap --><link href="https://cdn.bootcss.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet"> </head> <body> <div class="container"><div class="row clearfix"><div class="col-md-12 column"><div class="page-header"><h1><small>新增書籍</small></h1></div></div></div><form action="${pageContext.request.contextPath}/book/addBook" method="post">書籍名稱：<input type="text" name="bookName"><br><br><br>書籍?dāng)?shù)量：<input type="text" name="bookCounts"><br><br><br>書籍詳情：<input type="text" name="detail"><br><br><br><input type="submit" value="添加"></form></div>

方法三：修改書籍

6、BookController 類編寫

@RequestMapping("/toUpdateBook")public String toUpdateBook(Model model, int id) {Books books = bookService.queryBookById(id);System.out.println(books);model.addAttribute("book",books );return "updateBook";}@RequestMapping("/updateBook")public String updateBook(Model model, Books book) {System.out.println(book);bookService.updateBook(book);Books books = bookService.queryBookById(book.getBookID());model.addAttribute("books", books);return "redirect:/book/allBook";}

7、修改書籍頁(yè)面 WEB-INF.jsp.updateBook.jsp

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %> <%@ page contentType="text/html;charset=UTF-8" language="java" %> <html> <head><title>修改信息</title><meta name="viewport" content="width=device-width, initial-scale=1.0"><!-- 引入 Bootstrap --><link href="https://cdn.bootcss.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet"> </head> <body> <div class="container"><div class="row clearfix"><div class="col-md-12 column"><div class="page-header"><h1><small>修改信息</small></h1></div></div></div><form action="${pageContext.request.contextPath}/book/updateBook" method="post"><input type="hidden" name="bookID" value="${book.getBookID()}"/>書籍名稱：<input type="text" name="bookName" value="${book.getBookName()}"/>書籍?dāng)?shù)量：<input type="text" name="bookCounts" value="${book.getBookCounts()}"/>書籍詳情：<input type="text" name="detail" value="${book.getDetail() }"/><input type="submit" value="提交"/></form></div>

方法四：刪除書籍

8、BookController 類編寫

// 路徑變量，restfulAPI 風(fēng)格// 路徑變量的請(qǐng)求格式： 直接使用 {} 獲取參數(shù)// 如何讓參數(shù)識(shí)別這個(gè)請(qǐng)求中的位置，@PathVariable("bookId") 綁定請(qǐng)求過(guò)來(lái)的變量@RequestMapping("/del/{bookId}")public String deleteBook(@PathVariable("bookId") int id) {bookService.deleteBookById(id);return "redirect:/book/allBook";}

方法五：根據(jù)書名查詢書籍

9、BookController 類編寫

// 查詢書籍 前端--> 接收請(qǐng)求---> service--> mapper ---> 操作數(shù)據(jù)庫(kù)@RequestMapping("/queryBook")public String queryBook(String queryBookName,Model model){System.out.println("要查詢的數(shù)據(jù)名稱為："+queryBookName);// 查詢的業(yè)務(wù)邏輯Books books = bookService.queryBooksByName(queryBookName.trim());List<Books> list = new ArrayList<Books>();list.add(books);if (books==null){list = bookService.queryAllBook();model.addAttribute("error","沒(méi)有找到這本書");}model.addAttribute("list", list);return "allBook";}

刪除和查詢書籍都是在allBook的頁(yè)面執(zhí)行，因此不用重新寫對(duì)應(yīng)視圖頁(yè)面。

到目前為止，這個(gè)SSM項(xiàng)目整合已經(jīng)完全OK了，可以直接運(yùn)行進(jìn)行測(cè)試！

整個(gè)項(xiàng)目的全部目錄：

7. 配置Tomcat，進(jìn)行測(cè)試

注意：在測(cè)試之前，要在輸出目錄下創(chuàng)建lib包，導(dǎo)入整個(gè)項(xiàng)目的所有jar包

測(cè)試結(jié)果：
（在測(cè)試之前，在原數(shù)據(jù)庫(kù)中手動(dòng)新增了Python這本書，現(xiàn)在一共有4本書籍）
首頁(yè)

書籍列表頁(yè)

新增書籍

書籍列表新增了剛添加的C語(yǔ)言這本書

同時(shí)刷新后端數(shù)據(jù)庫(kù)的books表，也添加了這本書籍

查詢書籍


如果查詢書籍列表中沒(méi)有的書，如JavaMVC

結(jié)果顯示 沒(méi)有找到這本書

其余的刪除，修改操作均可實(shí)現(xiàn)，在此就不一 一演示！
