本文是基于xml配置的方式來整合SpringMVC、Spring和Mybatis（基于注解的方式會(huì)再寫一篇文章），步驟如下：

（1）首先自然是依賴包的配置文件 pom.xml

（2）既然是web項(xiàng)目，首先得配置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/javaeehttp://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="xuebusi" version="2.5"><display-name>xuebusi</display-name><welcome-file-list><welcome-file>index.html</welcome-file><welcome-file>index.htm</welcome-file><welcome-file>index.jsp</welcome-file><welcome-file>default.html</welcome-file><welcome-file>default.htm</welcome-file><welcome-file>default.jsp</welcome-file></welcome-file-list><!-- 加載spring容器 --><context-param><param-name>contextConfigLocation</param-name><param-value>classpath:spring/applicationContext-*.xml</param-value></context-param><listener><listener-class>org.springframework.web.context.ContextLoaderListener</listener-class></listener><!-- 解決post亂碼 --><filter><filter-name>CharacterEncodingFilter</filter-name><filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class><init-param><param-name>encoding</param-name><param-value>utf-8</param-value></init-param></filter><filter-mapping><filter-name>CharacterEncodingFilter</filter-name><url-pattern>/*</url-pattern></filter-mapping><!-- springmvc的前端控制器 --><servlet><servlet-name>dispatcherServlet</servlet-name><servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class><!-- contextConfigLocation不是必須的， 如果不配置contextConfigLocation， springmvc的配置文件默認(rèn)在：WEB-INF/servlet的name+"-servlet.xml" --><init-param><param-name>contextConfigLocation</param-name><param-value>classpath:spring/springmvc.xml</param-value></init-param><load-on-startup>1</load-on-startup></servlet><servlet-mapping><servlet-name>dispatcherServlet</servlet-name><url-pattern>/</url-pattern></servlet-mapping> </web-app>

（5）springmvc的配置文件 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: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.xsdhttp://www.springframework.org/schema/mvchttp://www.springframework.org/schema/mvc/spring-mvc-4.0.xsdhttp://www.springframework.org/schema/contexthttp://www.springframework.org/schema/context/spring-context.xsd"><context:component-scan base-package="com.xuebusi.xssm.controller" /><mvc:annotation-driven /><beanclass="org.springframework.web.servlet.view.InternalResourceViewResolver"><property name="prefix" value="/WEB-INF/jsp/" /><property name="suffix" value=".jsp" /></bean><!-- 資源映射 --><mvc:resources location="/WEB-INF/css/" mapping="/css/**"/><mvc:resources location="/WEB-INF/js/" mapping="/js/**"/><!-- 定義文件上傳解析器 --><bean id="multipartResolver"class="org.springframework.web.multipart.commons.CommonsMultipartResolver"><!-- 設(shè)定默認(rèn)編碼 --><property name="defaultEncoding" value="UTF-8"></property><!-- 設(shè)定文件上傳的最大值5MB，5*1024*1024 --><property name="maxUploadSize" value="5242880"></property></bean> </beans>

（6）Spring的配置文件applicationContext-service.xml 掃描@Service注解

<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans"xmlns:context="http://www.springframework.org/schema/context"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"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.xsd"><!-- 掃描包加載Service實(shí)現(xiàn)類 --><context:component-scan base-package="com.xuebusi.xssm.service"></context:component-scan> </beans>

（7）Spring的事物配置 applicationContext-trans.xml

<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans"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/beanshttp://www.springframework.org/schema/beans/spring-beans-4.0.xsdhttp://www.springframework.org/schema/aophttp://www.springframework.org/schema/aop/spring-aop-4.0.xsdhttp://www.springframework.org/schema/txhttp://www.springframework.org/schema/tx/spring-tx-4.0.xsd"><!-- 事務(wù)管理器 --><bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"><!-- 數(shù)據(jù)源 --><property name="dataSource" ref="dataSource"/></bean><!-- 通知 --><tx:advice id="txAdvice" transaction-manager="transactionManager"><tx:attributes><!-- 傳播行為 --><tx:method name="save*" propagation="REQUIRED"/><tx:method name="insert*" propagation="REQUIRED"/><tx:method name="add*" propagation="REQUIRED"/><tx:method name="create*" propagation="REQUIRED"/><tx:method name="delete*" propagation="REQUIRED"/><tx:method name="update*" propagation="REQUIRED"/><tx:method name="find*" propagation="SUPPORTS" read-only="true"/><tx:method name="select*" propagation="SUPPORTS" read-only="true"/><tx:method name="get*" propagation="SUPPORTS" read-only="true"/></tx:attributes></tx:advice><!-- 切面 --><aop:config><aop:advisor advice-ref="txAdvice" pointcut="execution(* com.xuebusi.xssm.service.*.*(..))"/></aop:config> </beans>

（8）Spring的數(shù)據(jù)源配置文件 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:xsi="http://www.w3.org/2001/XMLSchema-instance"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.xsd"><!-- 加載配置文件 --><context:property-placeholder location="classpath:resource/*.properties" /><!-- 數(shù)據(jù)庫連接池 --><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><!-- 配置sqlsessionFactory --><bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"><property name="configLocation" value="classpath:mybatis/SqlMapConfig.xml"></property><property name="dataSource" ref="dataSource"></property></bean><!-- 配置掃描包，加載mapper代理對(duì)象 --><bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"><property name="basePackage" value="com.xuebusi.xssm.mapper"></property></bean> </beans>

（9）redis配置文件 applicationContext-jedis.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"xsi:schemaLocation="http://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans-4.0.xsd"><!-- 連接池配置 --><bean id="jedisPoolConfig" class="redis.clients.jedis.JedisPoolConfig"><!-- 最大連接數(shù) --><property name="maxTotal" value="30" /><!-- 最大空閑連接數(shù) --><property name="maxIdle" value="10" /><!-- 每次釋放連接的最大數(shù)目 --><property name="numTestsPerEvictionRun" value="1024" /><!-- 釋放連接的掃描間隔（毫秒） --><property name="timeBetweenEvictionRunsMillis" value="30000" /><!-- 連接最小空閑時(shí)間 --><property name="minEvictableIdleTimeMillis" value="1800000" /><!-- 連接空閑多久后釋放, 當(dāng)空閑時(shí)間>該值 且 空閑連接>最大空閑連接數(shù) 時(shí)直接釋放 --><property name="softMinEvictableIdleTimeMillis" value="10000" /><!-- 獲取連接時(shí)的最大等待毫秒數(shù),小于零:阻塞不確定的時(shí)間,默認(rèn)-1 --><property name="maxWaitMillis" value="1500" /><!-- 在獲取連接的時(shí)候檢查有效性, 默認(rèn)false --><property name="testOnBorrow" value="true" /><!-- 在空閑時(shí)檢查有效性, 默認(rèn)false --><property name="testWhileIdle" value="true" /><!-- 連接耗盡時(shí)是否阻塞, false報(bào)異常,ture阻塞直到超時(shí), 默認(rèn)true --><property name="blockWhenExhausted" value="false" /></bean> <!-- jedis客戶端單機(jī)版 --><!--<bean id="redisClient" class="redis.clients.jedis.JedisPool"><constructor-arg name="host" value="localhost"></constructor-arg><constructor-arg name="port" value="6379"></constructor-arg><constructor-arg name="poolConfig" ref="jedisPoolConfig"></constructor-arg></bean><bean id="jedisClient" class="com.xuebusi.xssm.dao.impl.JedisClientSingle"/>--><!-- jedis集群版配置 --><bean id="redisClient" class="redis.clients.jedis.JedisCluster"><constructor-arg name="nodes"><set><bean class="redis.clients.jedis.HostAndPort"><constructor-arg name="host" value="192.168.71.13"></constructor-arg><constructor-arg name="port" value="7001"></constructor-arg></bean><bean class="redis.clients.jedis.HostAndPort"><constructor-arg name="host" value="192.168.71.13"></constructor-arg><constructor-arg name="port" value="7002"></constructor-arg></bean><bean class="redis.clients.jedis.HostAndPort"><constructor-arg name="host" value="192.168.71.13"></constructor-arg><constructor-arg name="port" value="7003"></constructor-arg></bean><bean class="redis.clients.jedis.HostAndPort"><constructor-arg name="host" value="192.168.71.13"></constructor-arg><constructor-arg name="port" value="7004"></constructor-arg></bean><bean class="redis.clients.jedis.HostAndPort"><constructor-arg name="host" value="192.168.71.13"></constructor-arg><constructor-arg name="port" value="7005"></constructor-arg></bean><bean class="redis.clients.jedis.HostAndPort"><constructor-arg name="host" value="192.168.71.13"></constructor-arg><constructor-arg name="port" value="7006"></constructor-arg></bean></set></constructor-arg><constructor-arg name="poolConfig" ref="jedisPoolConfig"></constructor-arg></bean><bean id="jedisClientCluster" class="com.xuebusi.xssm.dao.impl.JedisClientCluster"></bean></beans>

（10）在MySQL中創(chuàng)建一張x_user表

CREATE TABLE `x_user` (`id` int(11) NOT NULL AUTO_INCREMENT,`name` varchar(255) DEFAULT NULL,`address` varchar(255) DEFAULT NULL,`age` int(11) DEFAULT NULL,`phone` varchar(255) DEFAULT NULL,PRIMARY KEY (`id`) ) ENGINE=InnoDB AUTO_INCREMENT=4 DEFAULT CHARSET=utf8;

往表里插入幾條測試數(shù)據(jù)：

?

（11）通過mybatis的逆向工程生成x_user表對(duì)應(yīng)的實(shí)體類、接口類、Example類以及Mapper.xml配置文件，具體方法移步另一篇文章《mybatis逆向工程自動(dòng)生成實(shí)體類、接口以及映射Mapper.xml配置文件》，地址：http://www.cnblogs.com/jun1019/p/8073229.html

?

（12）編寫Controller類測試下

package com.xuebusi.xssm.controller;import com.xuebusi.xssm.pojo.XUser; import com.xuebusi.xssm.service.XUserService; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.PathVariable; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.ResponseBody;import java.util.List;/*** Created by SYJ on 2017/12/18.*/ @Controller @RequestMapping(value = "/user") public class XUserController {@Autowiredprivate XUserService userService;/*** 根據(jù)id查詢用戶* @param id* @return*/@RequestMapping(value = "/{id}")@ResponseBodypublic XUser get(@PathVariable("id") Integer id) {return userService.selectByPrimaryKey(id);}/*** 查詢所有用戶* @return*/@RequestMapping(value = "/list")@ResponseBodypublic List<XUser> list() {return userService.findAll();}/*** 添加用戶* @return*/@RequestMapping(value = "/add")@ResponseBodypublic int insert() {XUser user = new XUser();user.setName("王五");user.setAge(25);user.setPhone("13910108899");user.setAddress("重慶");return userService.insert(user);}}

（13） 編寫Service接口：

package com.xuebusi.xssm.service;import com.xuebusi.xssm.pojo.XUser;import java.util.List;/*** Created by SYJ on 2017/12/18.*/ public interface XUserService {XUser selectByPrimaryKey(Integer id);int insert(XUser user);List<XUser> findAll(); }

（14）編寫Service實(shí)現(xiàn)類：

package com.xuebusi.xssm.service.impl;import com.xuebusi.xssm.mapper.XUserMapper; import com.xuebusi.xssm.pojo.XUser; import com.xuebusi.xssm.service.XUserService; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Service;import java.util.List;/*** Created by SYJ on 2017/12/18.*/ @Service public class XUserServiceImpl implements XUserService {@Autowiredprivate XUserMapper userMapper;/*** 根據(jù)id查詢用戶* @param id* @return*/@Overridepublic XUser selectByPrimaryKey(Integer id) {XUser user = userMapper.selectByPrimaryKey(id);return user;}/*** 添加用戶* @param user* @return*/@Overridepublic int insert(XUser user) {return userMapper.insert(user);}/*** 查詢所有用戶* @return*/@Overridepublic List<XUser> findAll() {return userMapper.selectByExample(null);} }
