ssm框架搭建和整合流程
小編覺得挺不錯(cuò)的,現(xiàn)在分享給大家,幫大家做個(gè)參考.
Spring + SpringMVC + Mybatis整合流程
1????? 需求
1.1???? 客戶列表查詢
1.2???? 根據(jù)客戶姓名模糊查詢
2????? 整合思路
第一步：整合dao層
?????? Mybatis和spring整合，通過spring管理mapper接口，使用mapper掃描器自動(dòng)掃描mapper接口，并在spring中進(jìn)行注冊。
第二步：整合service層
?????? 通過spring管理service層，service調(diào)用mapper接口。使用配置方式將service接口配置在spring配置文件中，并且進(jìn)行事務(wù)控制。
第三步：整合springMVC
?????? 由于springMVC是spring的模塊，不需要整合。
3????? 準(zhǔn)備環(huán)境
3.1???? 數(shù)據(jù)庫版本
mysql5.7
3.2???? 編譯器
eclipse
3.3???? Jar 包
3.3.1???? spring的jar包
?
3.3.2???? spring與mybatis的整合jar包
?
3.3.3???? mybatis的jar包
?
3.3.4???? 數(shù)據(jù)庫驅(qū)動(dòng)包
?
3.3.5???? log4j包
?
3.3.6???? log4j配置文件
### direct log messages to stdout ### log4j.appender.stdout=org.apache.log4j.ConsoleAppender log4j.appender.stdout.Target=System.err log4j.appender.stdout.layout=org.apache.log4j.PatternLayout log4j.appender.stdout.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n ### direct messages to file mylog.log ### log4j.appender.file=org.apache.log4j.FileAppender log4j.appender.file.File=c:\mylog.log log4j.appender.file.layout=org.apache.log4j.PatternLayout log4j.appender.file.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n### set log levels - for more verbose logging change 'info' to 'debug' ### log4j.rootLogger=debug, stdout3.3.7???? dbcp數(shù)據(jù)庫連接池包
?
3.3.8???? jstl包
?
4????? 整合dao
4.1???? ?sqlMapconfig.xml
mybatis的配置文件：
<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN" "http://mybatis.org/dtd/mybatis-3-config.dtd"> <configuration><!-- 定義別名 --><typeAliases><package name="com.haohan.ssm.po" /></typeAliases><!-- 配置mapper映射文件 --><mappers><!-- 加載 原始dao使用映射文件 --><!-- <mapper resource="sqlmap/User.xml" /> -- <!--批量mapper掃描 遵循規(guī)則：將mapper.xml和mapper.java文件放在一個(gè)目錄 且文件名相同 ，現(xiàn)在由spring配置掃描--><!-- <package name="cn.itcast.ssm.dao.mapper" /> --></mappers> </configuration>4.2???? ?db.properties數(shù)據(jù)庫配置文件
jdbc.driver=com.mysql.jdbc.Driver jdbc.url=jdbc:mysql://localhost:3306/haohan1?characterEncoding=utf8&useSSL=false jdbc.username=root jdbc.password=1234564.3???? applicationContext-dao.xml
spring在這個(gè)xml文件中配置dbcp連接池，sqlSessionFactory，mapper的批量掃描。
?
<?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:context="http://www.springframework.org/schema/context"

4.4???? 逆向工程生成po類和mapper接口和mapper.xml文件
參考：http://how2j.cn/k/mybatis/mybatis-generator/1376.html
生成如下圖的文件：
?
4.5???? 自定義mapper接口和xml文件，以及po的包裝類
?

HhCustomVo
//客戶的包裝類 public class HhCustomVo {//客戶信息private HhCustom hhCustom;public HhCustom getHhCustom() {return hhCustom;}public void setHhCustom(HhCustom hhCustom) {this.hhCustom = hhCustom;} }4.6???? 數(shù)據(jù)庫表結(jié)構(gòu)
?
