SSM框架整合搭建教程 / 憋错料

自己配置了一个SSM框架，打算做个小网站，这里把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）

1 <?xml version="1.0" encoding="UTF-8" ?>
2 <!DOCTYPE configuration
3         PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
4         "http://mybatis.org/dtd/mybatis-3-config.dtd">
5 <configuration>
6
7 </configuration>

2.Dao，mybatis整合spring，通过spring管理

SqlSessionFactory、mapper代理对象

（resource/spring/applicationContext-dao.xml）

 1 <?xml version="1.0" encoding="UTF-8"?>
 2 <beans xmlns="http://www.springframework.org/schema/beans"
 3     xmlns:context="http://www.springframework.org/schema/context" xmlns:p="http://www.springframework.org/schema/p"
 4     xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"

 8     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
 9     http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-4.0.xsd">
10
11     <!-- 数据库连接池 -->
12     <!-- 加载配置文件 -->
13     <context:property-placeholder location="classpath:*.properties" />
14     <!-- 数据库连接池 -->
15     <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource"
16         destroy-method="close">
17         <property name="url" value="${jdbc.url}" />
18         <property name="username" value="${jdbc.username}" />
19         <property name="password" value="${jdbc.password}" />
20         <property name="driverClassName" value="${jdbc.driver}" />
21         <property name="maxActive" value="10" />
22         <property name="minIdle" value="5" />
23     </bean>
24     <!-- 让spring管理sqlsessionfactory 使用mybatis和spring整合包中的 -->
25     <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
26         <!-- 数据库连接池 -->
27         <property name="dataSource" ref="dataSource" />
28         <!-- 加载mybatis的全局配置文件 -->
29         <property name="configLocation" value="classpath:mybatis/SqlMapConfig.xml" />
30     </bean>
31     <!-- 自动扫描 将Mapper接口生成代理注入到Spring -->
32     <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
33         <property name="basePackage" value="com.mapper" />
34     </bean>
35 </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）

 1 <?xml version="1.0" encoding="UTF-8"?>
 2 <beans xmlns="http://www.springframework.org/schema/beans"
 3     xmlns:context="http://www.springframework.org/schema/context" xmlns:p="http://www.springframework.org/schema/p"
 4     xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"
 5     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 6     xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd
 7     http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd
 8     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
 9     http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-4.0.xsd">
10
11         <!-- spring自动去扫描base-pack下面或者子包下面的java文件-->
12         <!--管理Service实现类-->
13         <context:component-scan base-package="com.service"/>
14 </beans>

配置spring管理实务

（resource/spring/applicationContext-trans.xml）

 1 <?xml version="1.0" encoding="UTF-8"?>
 2 <beans xmlns="http://www.springframework.org/schema/beans"
 3     xmlns:context="http://www.springframework.org/schema/context" xmlns:p="http://www.springframework.org/schema/p"
 4     xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"
 5     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 6     xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd
 7     http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd
 8     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
 9     http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-4.0.xsd">
10     <!-- 事务管理器 -->
11     <bean id="transactionManager"
12         class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
13         <!-- 数据源 -->
14         <property name="dataSource" ref="dataSource" />
15     </bean>
16     <!-- 通知 -->
17     <tx:advice id="txAdvice" transaction-manager="transactionManager">
18         <tx:attributes>
19             <!-- 传播行为 -->
20             <tx:method name="save*" propagation="REQUIRED" />
21             <tx:method name="insert*" propagation="REQUIRED" />
22             <tx:method name="add*" propagation="REQUIRED" />
23             <tx:method name="create*" propagation="REQUIRED" />
24             <tx:method name="delete*" propagation="REQUIRED" />
25             <tx:method name="update*" propagation="REQUIRED" />
26             <tx:method name="find*" propagation="SUPPORTS" read-only="true" />
27             <tx:method name="select*" propagation="SUPPORTS" read-only="true" />
28             <tx:method name="get*" propagation="SUPPORTS" read-only="true" />
29         </tx:attributes>
30     </tx:advice>
31     <!-- 切面 -->
32     <aop:config>
33         <aop:advisor advice-ref="txAdvice"
34             pointcut="execution(* com.service.*.*(..))" />
35     </aop:config>
36 </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">
		<level value="error" />
	</logger>

	<logger name="org.springframework.context">
		<level value="error" />
	</logger>

	<logger name="org.springframework.web">
		<level value="error" />
	</logger>

	<logger name="org.springframework.jdbc">
		<level value="error" />
	</logger>

	<logger name="org.mybatis.spring">
		<level value="error" />
	</logger>
	<logger name="java.sql">
		<level value="error" />
	</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

 1 package com.controller;
 2
 3 import javax.annotation.Resource;
 4 import javax.servlet.http.HttpServletRequest;
 5 import org.springframework.stereotype.Controller;
 6 import org.springframework.web.bind.annotation.RequestMapping;
 7 import org.springframework.web.servlet.ModelAndView;
 8 import com.pojo.User;
 9 import com.service.UserService;
10
11 @Controller
12 @RequestMapping("/user")
13 public class UserController {
14
15     @Resource(name="userService")
16     private UserService userService;
17     /**
18      * 根据id查询
19      */
20     @RequestMapping(value="/queryById")
21     public ModelAndView queryById(HttpServletRequest request){
22         ModelAndView mv = new ModelAndView();
23         String id = request.getParameter("id");
24         try{
25             User var = userService.findById(id);
26             mv.setViewName("index");
27             mv.addObject("var", var);
28         } catch(Exception e){
29             e.printStackTrace();
30         }
31         return mv;
32     }
33 }

UserService.java

 1 package com.service;
 2
 3 import javax.annotation.Resource;
 4
 5 import org.springframework.stereotype.Service;
 6
 7 import com.mapper.UserMapper;
 8 import com.pojo.User;
 9
10 @Service("userService")
11 public class UserService {
12     @Resource
13     private UserMapper dao;
14     /*
15     * 通过id获取数据
16     */
17     public User findById(String id)throws Exception{
18         return (User)dao.selectByPrimaryKey(id);
19     }
20 }

补上之前漏掉得web.xml配置
