SSM 框架-05-详细整合教程(Eclipse版)(Spring+SpringMVC+MyBatis)
如果你使用的是 Intellij IDEA,请查看:
SSM的配置流程详细的写了出来,方便很少接触这个框架的朋友使用,文中各个资源均免费提供!
一.创建web项目(eclipse)
File-->new-->Dynamic Web Project (这里我们创建的项目名为SSM)
下面是大致目录结构
二. SSM所需jar包。
jar包链接:https://pan.baidu.com/s/1dTClhO 密码:n4mm
三.整合开始
1.mybatis配置文件(resource/mybatis/SqlMapConfig.xml)
- <?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>
-
- </configuration>
2.Dao,mybatis整合spring,通过spring管理
SqlSessionFactory、mapper代理对象
(resource/spring/applicationContext-dao.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:p="http://www.springframework.org/schema/p"
- xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"
- xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
- xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd
- http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd
- http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd
- http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-4.0.xsd">
-
- <!-- 数据库连接池 -->
- <!-- 加载配置文件 -->
- <context:property-placeholder location="classpath:*.properties" />
- <!-- 数据库连接池 -->
- <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource"
- destroy-method="close">
- <property name="url" value="${jdbc.url}" />
- <property name="username" value="${jdbc.username}" />
- <property name="password" value="${jdbc.password}" />
- <property name="driverClassName" value="${jdbc.driver}" />
- <property name="maxActive" value="10" />
- <property name="minIdle" value="5" />
- </bean>
- <!-- 让spring管理sqlsessionfactory 使用mybatis和spring整合包中的 -->
- <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
- <!-- 数据库连接池 -->
- <property name="dataSource" ref="dataSource" />
- <!-- 加载mybatis的全局配置文件 -->
- <property name="configLocation" value="classpath:mybatis/SqlMapConfig.xml" />
- </bean>
- <!-- 自动扫描 将Mapper接口生成代理注入到Spring -->
- <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
- <property name="basePackage" value="com.mapper" />
- </bean>
- </beans>
这里用的是阿里的连接池,当然也可以用c3p0,个人建议用阿里
3. 所有的实现类都放到spring容器中管理。由spring创建数据库连接池,并有spring管理实务。
(resource/spring/applicationContext-service.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:p="http://www.springframework.org/schema/p"

-
- <!-- spring自动去扫描base-pack下面或者子包下面的java文件-->
- <!--管理Service实现类-->
- <context:component-scan base-package="com.service"/>
- </beans>
配置spring管理实务
(resource/spring/applicationContext-trans.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:p="http://www.springframework.org/schema/p"

- <!-- 切面 -->
- <aop:config>
- <aop:advisor advice-ref="txAdvice"
- pointcut="execution(* com.service.*.*(..))" />
- </aop:config>
- </beans>
4. Springmvc整合spring框架,由springmvc管理controller
(resource/spring/springmvc.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" 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/beans http://www.springframework.org/schema/beans/spring-beans.xsd
- http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd
- http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">
-
- <!-- 扫描controller -->
- <context:component-scan base-package="com.controller" />
-
- <!-- Spring 来扫描指定包下的类,并注册被@Component,@Controller,@Service,@Repository等注解标记的组件 -->
- <mvc:annotation-driven />
-
- <!-- 配置SpringMVC的视图解析器-->
- <bean
- class="org.springframework.web.servlet.view.InternalResourceViewResolver">
- <property name="prefix" value="/WEB-INF/jsp/" />
- <property name="suffix" value=".jsp" />
- </bean>
- </beans>
5. 2中加载的属性配置文件(dbconfig.properties)
根据自己的数据库更改用户名密码以及库
- jdbc.driver=com.mysql.jdbc.Driver
- jdbc.url=jdbc:mysql://localhost:3306/ssm?characterEncoding=utf-8
- jdbc.username=root
- jdbc.password=123456
6. 配置log4j
(log4j.properties)
- log4j.rootLogger=error,CONSOLE,A
- log4j.addivity.org.apache=false
-
- log4j.appender.CONSOLE=org.apache.log4j.ConsoleAppender
- log4j.appender.CONSOLE.Threshold=error
- log4j.appender.CONSOLE.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} -%-4r [%t] %-5p %x - %m%n
- log4j.appender.CONSOLE.Target=System.out
- log4j.appender.CONSOLE.Encoding=gbk
- log4j.appender.CONSOLE.layout=org.apache.log4j.PatternLayout
-
-
- log4j.appender.A=org.apache.log4j.DailyRollingFileAppender
- log4j.appender.A.File=${catalina.home}/logs/FH_log/PurePro_
- log4j.appender.A.DatePattern=yyyy-MM-dd'.log'
- log4j.appender.A.layout=org.apache.log4j.PatternLayout
- log4j.appender.A.layout.ConversionPattern=[FH_sys] %d{yyyy-MM-dd HH:mm:ss} %5p %c{1}:%L : %m%n
-
-
(log4j.xml)
- <?xml version="1.0" encoding="UTF-8"?>
- <!DOCTYPE log4j:configuration PUBLIC "-//APACHE//DTD LOG4J 1.2//EN" "log4j.dtd">
- <log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/">
-
- <!-- Appenders -->
- <appender name="console" class="org.apache.log4j.ConsoleAppender">
- <param name="Target" value="System.out" />
- <layout class="org.apache.log4j.PatternLayout">
- <param name="ConversionPattern" value="%d{yyyy HH:mm:ss} %-5p %c - %m%n" />
- </layout>
- </appender>
-
- <!-- Application Loggers -->
- <logger name="com">
- <level value="error" />
- </logger>
-
- <!-- 3rdparty Loggers -->
- <logger name="org.springframework.core">
- <level value="error" />
- </logger>
-
- <logger name="org.springframework.beans">

- </logger>
- <!-- Root Logger -->
- <root>
- <priority value="error" />
- <appender-ref ref="console" />
- </root>
-
- </log4j:configuration>
SSM框架整合完成,至于mybatis逆向工程生成的mapper.xml和pojo请放到第一张图的目录下
注:逆向工程是根据数据库表反向生成pojo以及mapper.xml,所以,请先自动在数据库配置好user表。逆向工程得配置在下面得链接里面有详细注释。
测试数据库表(User)
private String id;
private String username;
private String password;
private String company;
private Integer age;
private Integer sex;
根据类型创建表即可
逆向工程项目我会贴出链接,解压导入改路径运行main方法就会自动生成了,注意配置生成的路径
逆向工程链接: 链接:https://pan.baidu.com/s/1QvSskH2UEC6EQF7MgVDOAQ 密码:t2pc
到这里项目整合完成,接下来是测试!
UserController.java
- package com.controller;
-
- import javax.annotation.Resource;
- import javax.servlet.http.HttpServletRequest;
- import org.springframework.stereotype.Controller;
- import org.springframework.web.bind.annotation.RequestMapping;
- import org.springframework.web.servlet.ModelAndView;
- import com.pojo.User;
- import com.service.UserService;
-
- @Controller
- @RequestMapping("/user")
- public class UserController {
-
- @Resource(name="userService")
- private UserService userService;
- /**
- * 根据id查询
- */
- @RequestMapping(value="/queryById")
- public ModelAndView queryById(HttpServletRequest request){
- ModelAndView mv = new ModelAndView();
- String id = request.getParameter("id");
- try{
- User var = userService.findById(id);
- mv.setViewName("index");
- mv.addObject("var", var);
- } catch(Exception e){
- e.printStackTrace();
- }
- return mv;
- }
- }
UserService.java
- package com.service;
-
- import javax.annotation.Resource;
-
- import org.springframework.stereotype.Service;
-
- import com.mapper.UserMapper;
- import com.pojo.User;
-
- @Service("userService")
- public class UserService {
- @Resource
- private UserMapper dao;
- /*
- * 通过id获取数据
- */
- public User findById(String id)throws Exception{
- return (User)dao.selectByPrimaryKey(id);
- }
- }
补上之前漏掉得web.xml配置
- <?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" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"

为节省篇幅,更快的搭建成功,这里只写了一个方法,根据id查询数据
WebContent/index.jsp
