2.4. 初始化web.xml

<?xml version="1.0" encoding="UTF-8"?> <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xmlns="http://java.sun.com/xml/ns/javaee"xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"version="3.0"><display-name>Archetype Created Web Application</display-name><welcome-file-list><welcome-file>/index.jsp</welcome-file></welcome-file-list><!-- 加載spring bean --><context-param><param-name>contextConfigLocation</param-name><param-value>classpath:applicationContext.xml</param-value></context-param><listener><listener-class>org.springframework.web.context.ContextLoaderListener</listener-class></listener><!-- 編碼過濾器 --><filter><filter-name>encodingFilter</filter-name><filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class><async-supported>true</async-supported><init-param><param-name>encoding</param-name><param-value>UTF-8</param-value></init-param><init-param><param-name>forceEncoding</param-name><param-value>true</param-value></init-param></filter><filter-mapping><filter-name>encodingFilter</filter-name><url-pattern>/*</url-pattern></filter-mapping><!-- Spring MVC servlet --><servlet><servlet-name>SpringMVC</servlet-name><servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class><init-param><param-name>contextConfigLocation</param-name><param-value>classpath:spring-mvc.xml</param-value></init-param><load-on-startup>1</load-on-startup><async-supported>true</async-supported></servlet><servlet-mapping><servlet-name>SpringMVC</servlet-name><url-pattern>*.do</url-pattern></servlet-mapping></web-app>

2.5創建配置文件

• 在resources下面創建applicationContext.xml和spring-mvc.xml配置文件
  applicationContext.xml配置文件

<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"xmlns:context="http://www.springframework.org/schema/context"xmlns:mvc="http://www.springframework.org/schema/mvc"xsi:schemaLocation="http://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans-4.0.xsdhttp://www.springframework.org/schema/contexthttp://www.springframework.org/schema/context/spring-context-4.0.xsdhttp://www.springframework.org/schema/mvchttp://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd"><!-- 使用注解式注入 --><context:annotation-config /><!-- 自動掃描 --><context:component-scan base-package="com.gblfy" /></beans>

spring-mvc.xml配置文件

<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"xmlns:context="http://www.springframework.org/schema/context"xmlns:mvc="http://www.springframework.org/schema/mvc"xsi:schemaLocation="http://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans-4.0.xsdhttp://www.springframework.org/schema/contexthttp://www.springframework.org/schema/context/spring-context-4.0.xsdhttp://www.springframework.org/schema/mvchttp://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd"><!--避免IE執行AJAX時，返回JSON出現下載文件 --><bean id="mappingJacksonHttpMessageConverter"class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter"><property name="supportedMediaTypes"><list><value>text/html;charset=UTF-8</value></list></property></bean><!-- 添加注解驅動 --><mvc:annotation-driven /><mvc:default-servlet-handler /><!-- 設置使用注解的類所在的包 --><context:component-scan base-package="com.gblfy.controller" /><!-- 完成請求和注解POJO的映射 --><beanclass="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter"><property name="messageConverters"><list><ref bean="mappingJacksonHttpMessageConverter" /> <!-- JSON轉換器 --></list></property></bean><!-- 定義跳轉的文件的前后綴 ，視圖模式配置 --><beanclass="org.springframework.web.servlet.view.InternalResourceViewResolver"><!-- 這里的配置我的理解是自動給后面action的方法return的字符串加上前綴和后綴，變成一個 可用的url地址 --><property name="prefix" value="/WEB-INF/jsp/" /><property name="suffix" value=".jsp" /></bean><!-- SpringMVC上傳文件時，需要配置MultipartResolver處理器 --><bean id="multipartResolver"class="org.springframework.web.multipart.commons.CommonsMultipartResolver"><!-- 默認編碼 --><property name="defaultEncoding" value="utf-8" /><!-- 文件大小最大值 --><property name="maxUploadSize" value="10485760000" /><!-- 內存中的最大值 --><property name="maxInMemorySize" value="40960" /></bean></beans>

2.6. 創建測試類

在Java目錄下面創建com.gblfy.controller包，并在寶下面創建HelloWorldController

package com.gblfy.controller;import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping;@Controller public class HelloWorldController {@RequestMapping("/hello")public String hello(){return "Springmvc項目搭建成功！！！";} }

三、配置tomcat

3.1. 選擇配置

3.2. 選擇tomcat

點擊加號，下拉選擇

3.3. 配置tomcat路徑

3.4. 把項目添加到tomcat中

3.5. 啟動驗證

3.6. 默認訪問index.jsp
