一、配置数据库连接参数，用于引入到数据库连接池：
db.properties文件：
jdbc.driver=com.mysql.jdbc.Driver jdbc.url=jdbc:mysql://localhost:端口号/数据库名?useUnicode=true&characterEncoding=utf8 jdbc.username=root jdbc.password=数据库连接密码 jdbc.maxActive=10 jdbc.minIdle=5
二、DAO层配置，也就是Mybatis配置：
1、mybatis默认配置文件（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> //配置在其他地方，这里不做配置 </configuration>
2、mybatis基本配置（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"> <!-- 读取db.properties,通过bean的方式创建，spEL方式取值（#｛dbConfig.xxx｝） <util:properties id="dbConfig" location="classpath:db.properties"></util:properties> --> <!-- 配置数据库连接池 --> <!-- 加载配置文件db.properties数据库连接参数配置 --> <context:property-placeholder location="classpath:resource/db.properties" /> <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource" destroy-method="close"> <property name="url" value="${jdbc.url}"></property> <property name="driverClassName" value="${jdbc.driver}"></property> <property name="username" value="${jdbc.username}"></property> <property name="password" value="${jdbc.password}"></property> <property name="maxActive" value="${jdbc.maxActive}"></property> <property name="minIdle" value="${jdbc.minIdle}"></property> </bean> <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <!-- mybatis默认文件在哪里 --> <property name="configLocation" value="classpath:mybatis/sqlMapConfig.xml"></property> <!--XML文件在哪里 --> <property name="mapperLocations" value="classpath:mapper/*.xml"></property> <!-- 数据源在哪里 --> <property name="dataSource" ref="dataSource"></property> </bean> <!-- 配置扫描包，加载mapper的代理对象 --> <bean id="mapperScanner" class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <property name="basePackage" value="top.hzelin.jingxi.mapper"></property> </bean> </beans>
三、Service层配置，包括事务配置（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" 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"> <!-- 扫描包， 加载service实现类--> <context:component-scan base-package="top.hzelin.jingxi.service" /> <!-- 事务管理器 --> <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <!-- 数据源 --> <property name="dataSource" ref="dataSource"></property> </bean> <tx:annotation-driven transaction-manager="transactionManager"/> <!-- 通知 --> <tx:advice id="txAdvice" transaction-manager="transactionManager"> <tx:attributes> <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="save*" 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,注意需要依赖：
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-aspects</artifactId>
</dependency>
-->
<aop:config >
<aop:advisor advice-ref="txAdvice"
pointcut="execution(* top.hzelin.jingxi.service.*.*(..))"/>
</aop:config>
</beans>
四、Controller层配置（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"> <!-- 扫描包，加载controller实现类 --> <context:component-scan base-package="top.hzelin.jingxi.controller" /> <!--注解驱动 --> <mvc:annotation-driven /> <!-- 视图解析器 --> <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="WEB-INF/jsp/"></property> <property name="suffix" value=".jsp"></property> </bean> <!--资源映射 --> <mvc:resources location="/WEB-INF/css/" mapping="/css/**" /> <mvc:resources location="/WEB-INF/js/" mapping="/js/**" /> </beans>
五、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" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" version="2.5">
<display-name>jingxi-manager-web</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>
<!-- 加载spring容器 -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring/applicationContext-*.xml</param-value>
</context-param>
<!-- 配置监听器 -->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<!-- 过滤器处理乱码 -->
<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>
<!-- 前端可控制器 -->
<servlet>
<servlet-name>SpringMVC</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<!-- 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" -->
<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>SpringMVC</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
</web-app>
