篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了SSM框架整合搭建教程相关的知识，希望对你有一定的参考价值。
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" 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 <!-- 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

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
1 <?xml version="1.0" encoding="UTF-8"?> 2 <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 3 xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" 4 xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" 5 id="WebApp_ID" version="2.5"> 6 <welcome-file-list> 7 <welcome-file>index.jsp</welcome-file> 8 </welcome-file-list> 9 <!-- 加载spring容器 --> 10 <context-param> 11 <param-name>contextConfigLocation</param-name> 12 <param-value>classpath:spring/applicationContext*.xml</param-value> 13 </context-param> 14 <listener> 15 <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> 16 </listener> 17 18 <!-- 解决post乱码 --> 19 <filter> 20 <filter-name>CharacterEncodingFilter</filter-name> 21 <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> 22 <init-param> 23 <param-name>encoding</param-name> 24 <param-value>utf-8</param-value> 25 </init-param> 26 <!-- <init-param> 27 <param-name>forceEncoding</param-name> 28 <param-value>true</param-value> 29 </init-param> --> 30 </filter> 31 <filter-mapping> 32 <filter-name>CharacterEncodingFilter</filter-name> 33 <url-pattern>/*</url-pattern> 34 </filter-mapping> 35 36 37 <!-- springmvc的前端控制器 --> 38 <!-- <servlet> 39 <servlet-name>taotao-manager</servlet-name> 40 <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> 41 contextConfigLocation不是必须的， 如果不配置contextConfigLocation， springmvc的配置文件默认在：WEB-INF/servlet的name+"-servlet.xml" 42 <init-param> 43 <param-name>contextConfigLocation</param-name> 44 <param-value>classpath:spring/springmvc.xml</param-value> 45 </init-param> 46 <load-on-startup>1</load-on-startup> 47 </servlet> 48 <servlet-mapping> 49 <servlet-name>SSM</servlet-name> 50 <url-pattern>/</url-pattern> 51 </servlet-mapping> --> 52 53 <servlet> 54 <servlet-name>springMvc</servlet-name> 55 <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> 56 <init-param> 57 <param-name>contextConfigLocation</param-name> 58 <param-value>classpath:spring/springmvc.xml</param-value> 59 </init-param> 60 <load-on-startup>1</load-on-startup> 61 </servlet> 62 <servlet-mapping> 63 <servlet-name>springMvc</servlet-name> 64 <url-pattern>/</url-pattern> 65 </servlet-mapping> 66 67 </web-app>
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
<%@ page language="java" contentType="text/html; charset=utf-8" pageEncoding="utf-8"%> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <% String path = request.getContextPath(); String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/"; %> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> <title>查询用户</title> </head> <body> <form action="user/queryById.do" method="post"> 输入要查询的id: <input type="text" name="id" value="123456"/> <button type="submit">提交</button> </form> </body> </html>
WebContent/WEB-INF/jsp/index.jsp

启动项目，输入localhost:8080/SSM 访问
为方便新手查错，博主按照博文重新搭建了一次，测试无误后将项目打包，上传至云盘，供您使用。（建议：希望您按照博文从头搭建，便于印象深刻）
