一、配置文件的分工
spring配置文件：
1、配置扫描包,排除Controller、ControllerAdvice
2、导入属性文件
3、数据库连接池的数据源
4、配置事务管理器（datasource属性）
5、开启基于注解的事务<tx:annotation-driven transaction-manager="dataSourceTransactionManager"/>
6、配置SqlSessionFactoryBean对象，（dataSource和configLocation属性）
7、配置MapperScannerConfigurer对象（basePackage属性：mapper包扫描）
<?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:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd"> <!-- 配置扫描包 --> <context:component-scan base-package="com.neuedu.orm"> <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/> <context:exclude-filter type="annotation" expression="org.springframework.web.bind.annotation.ControllerAdvice"/> </context:component-scan> <!-- 配置属性文件 --> <context:property-placeholder location="classpath:jdbc.properties"/> <!-- 配置数据库连接 --> <bean id="comboPooledDataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"> <property name="driverClass" value="${jdbc.driverClass}"></property> <property name="jdbcUrl" value="${jdbc.jdbcUrl}"></property> <property name="user" value="${jdbc.user}"></property> <property name="password" value="${jdbc.password}"></property> </bean> <!-- 配置事务管理器 --> <bean id="dataSourceTransactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <property name="dataSource" ref="comboPooledDataSource"></property> </bean> <!-- 开启基于注解的事务 --> <tx:annotation-driven transaction-manager="dataSourceTransactionManager"/> <!-- 配置SqlSessionFactoryBean --> <bean class="org.mybatis.spring.SqlSessionFactoryBean"> <property name="dataSource" ref="comboPooledDataSource"></property> <property name="configLocation" value="classpath:mybatis-config.xml"></property> </bean> <!-- 配置 MapperScannerConfigurer--> <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <property name="basePackage" value="com.neuedu.orm.mapper"></property> </bean> </beans>
mybatis配置文件：
1、settings的配置
配置：数据库字段转换为驼峰式命名
开启二级缓存
开启懒加载
<?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> <settings> <setting name="mapUnderscoreToCamelCase" value="true"/> <setting name="lazyLoadingEnabled" value="true"/> <setting name="aggressiveLazyLoading" value="false"/> </settings> </configuration>
spring mvc配置文件：
1、配置扫描包，只扫描Controller、ControllerAdvice
2、配置视图解析器InternalResourceViewResolver
3、配置处理静态资源文件：<mvc:default-servlet-handler/>
4、配置<mvc:annotation-driven></mvc:annotation-driven>
5、配置<mvc:view-controller path="/abc" view-name="success"/>
<?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/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd"> <!-- 配置扫描包 --> <context:component-scan base-package="com.neuedu.orm" use-default-filters="false"> <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/> <context:include-filter type="annotation" expression="org.springframework.web.bind.annotation.ControllerAdvice"/> </context:component-scan> <!-- 配置视图解析器 --> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/WEB-INF/pages/"></property> <property name="suffix" value=".jsp"></property> </bean> <!-- 配置处理静态资源文件 --> <mvc:default-servlet-handler/> <!-- --> <mvc:annotation-driven></mvc:annotation-driven> <mvc:view-controller path="/abc" view-name="success"/> </beans>
web.xml配置文件：
1、配置生命周期监听器ContextLoaderListener，加载IOC容器
2、配置前端控制器DispatcherServlet
3、配置字符集过滤器CharacterEncodingFilter
4、配置Spring MVC过滤器HiddenHttpMethodFilter，使得支持GET、POST、PUT与DELETE请求
<?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>orm</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> <!-- 配置生命周期监听器ContextLoaderListener，加载IOC容器 --> <!-- needed for ContextLoaderListener --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:applicationContext.xml</param-value> </context-param> <!-- Bootstraps the root web application context before servlet initialization --> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!-- 配置前端控制器 --> <!-- The front controller of this Spring Web application, responsible for handling all application requests --> <servlet> <servlet-name>springDispatcherServlet</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:springmvc.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <!-- Map all requests to the DispatcherServlet for handling --> <servlet-mapping> <servlet-name>springDispatcherServlet</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> <!-- 配置CharacterEncodingFilter --> <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> <!-- 配置Spring MVC过滤器HiddenHttpMethodFilter，使得支持GET、POST、PUT与DELETE请求 --> <filter> <filter-name>HiddenHttpMethodFilter</filter-name> <filter-class>org.springframework.web.filter.HiddenHttpMethodFilter</filter-class> </filter> <filter-mapping> <filter-name>HiddenHttpMethodFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> </web-app>
