3.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" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" version="2.5"> <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> <init-param> <param-name>forceEncoding</param-name> <param-value>true</param-value> </init-param> </filter> <filter-mapping> <filter-name>CharacterEncodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <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> <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> <servlet> <servlet-name>dispatcherServlet</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> <servlet-mapping> <servlet-name>dispatcherServlet</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> </web-app>
解释：
第一个CharacterEncodingFilter是用来转换springmvc字符集的，最好放在第一个过滤。
第二个HiddenHttpMethodFilter是用来支持REST风格的URL。
第三个ContextLoaderListener是用来监听启动spring容器的，使用的正则表达式匹配哪些application文件。
第四个dispatcherServlet是springmvc的控制器用来对请求进行控制转发的，它的url-pattern只能为/而不能为/*。
4.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/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 http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd"> <!-- 配置自动扫描的包 --> <context:component-scan base-package="com.atguigu.springmvc" 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> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/WEB-INF/views/"></property> <property name="suffix" value=".jsp"></property> </bean> <bean class="org.springframework.web.servlet.view.BeanNameViewResolver"> <property name="order" value="100"></property> </bean> <bean id="messageSource" class="org.springframework.context.support.ResourceBundleMessageSource"> <property name="basename" value="i18n"></property> </bean> <mvc:view-controller path="/success" view-name="success"/> <mvc:default-servlet-handler/> <mvc:annotation-driven></mvc:annotation-driven> <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver"> <property name="defaultEncoding" value="UTF-8"></property> <property name="maxUploadSize" value="1024000"></property> </bean> <mvc:interceptors> <bean class="com.atguigu.springmvc.interceptors.FirstInterceptor"/> </mvc:interceptors> </beans>
解释：
第一：context:component-scan只扫描特定注解的类。
第二：InternalResourceViewResolver视图解析器。
第三：BeanNameViewResolver自定义视图解析器。
第四：ResourceBundleMessageSource国际化。
第五：直接访问/success跳转到相应的视图。
第六：<mvc:default-servlet-handler/>让不能解析的url丢给服务器去默认解析，例如js,css文件。
第七：<mvc:annotation-driven>加载默认的HandlerMapper以及HandlerMapperAdapter。
第八：multipartResolver文件上传控制。
第九：FirstInterceptor拦截器。

<?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" xsi:schemaLocation="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"> <!-- 配置数据源, 整合其他框架, 事务等. --> <!-- 加载配置文件 --> <context:property-placeholder location="classpath:db.properties" /> <!-- 数据源，使用dbcp --> <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource" destroy-method="close"> <property name="driverClass" value="${jdbc.driverClass}" /> <property name="jdbcUrl" value="${jdbc.jdbcUrl}" /> <property name="user" value="${jdbc.user}" /> <property name="password" value="${jdbc.password}" /> <property name="minPoolSize" value="${jdbc.miniPoolSize}" /> <property name="maxPoolSize" value="${jdbc.maxPoolSize}" /> <property name="initialPoolSize" value="${jdbc.initialPoolSize}" /> <property name="maxIdleTime" value="${jdbc.maxIdleTime}" /> <property name="acquireIncrement" value="${jdbc.acquireIncrement}" /> <property name="acquireRetryAttempts" value="${jdbc.acquireRetryAttempts}" /> <property name="acquireRetryDelay" value="${jdbc.acquireRetryDelay}" /> <property name="testConnectionOnCheckin" value="${jdbc.testConnectionOnCheckin}" /> <property name="automaticTestTable" value="${jdbc.automaticTestTable}" /> <property name="idleConnectionTestPeriod" value="${jdbc.idleConnectionTestPeriod}" /> <property name="checkoutTimeout" value="${jdbc.checkoutTimeout}" /> </bean> <!-- sqlSessinFactory --> <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <!-- 加载mybatis的配置文件 --> <property name="configLocation" value="classpath:mybatis/SqlMapConfig.xml" /> <!-- 数据源 --> <property name="dataSource" ref="dataSource" /> </bean> <!-- mapper配置 MapperFactoryBean：根据mapper接口生成代理对象，和下面方式二选一 --> <!-- <bean id="userMapper" class="org.mybatis.spring.mapper.MapperFactoryBean"> <property name="mapperInterface" value="com.alibaba.mapper.UserMapper"/> <property name="sqlSessionFactory" ref="sqlSessionFactory"/> </bean> --> <!-- mapper批量扫描，从mapper包中扫描出mapper接口，自动创建代理对象并且在spring容器中注册 遵循规范：将mapper.java和mapper.xml映射文件名称保持一致，且在一个目录 中 自动扫描出来的mapper的bean的id为mapper类名（首字母小写） --> <!-- 指定扫描的包名 如果扫描多个包，每个包中间使用半角逗号分隔 --> <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <property name="basePackage" value="com.atguigu.springmvc.crud.mapper"/> <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/> </bean> </beans>
6.db.properties
jdbc.driverClass=com.mysql.jdbc.Driver
jdbc.jdbcUrl = jdbc:mysql://localhost:3306/test
jdbc.user = root
jdbc.password = 123456
jdbc.miniPoolSize = 1
jdbc.maxPoolSize = 20
jdbc.initialPoolSize = 1

7.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> <settings> <!-- 打开延迟加载 的开关 --> <setting name="lazyLoadingEnabled" value="true" /> <!-- 将积极加载改为消极加载即按需要加载 --> <setting name="aggressiveLazyLoading" value="false" /> <!-- 开启二级缓存 --> <setting name="cacheEnabled" value="true" /> </settings> <!-- 别名定义 --> <typeAliases> <!-- 批量别名定义 指定包名，mybatis自动扫描包中的po类，自动定义别名，别名就是类名（首字母大写或小写都可以） --> <package name="com.atguigu.springmvc.crud.entities" /> </typeAliases> <!-- 加载 映射文件 --> <mappers> <mapper resource="mybatis/UserMapper.xml" /> <!-- 批量加载mapper 指定mapper接口的包名，mybatis自动扫描包下边所有mapper接口进行加载 遵循一些规范：需要将mapper接口类名和mapper.xml映射文件名称保持一致，且在一个目录 中 上边规范的前提是：使用的是mapper代理方法 和spring整合后，使用mapper扫描器，这里不需要配置了 --> <!-- <package name="com.alibaba.mapper"/> --> </mappers> </configuration>
8.使用ehcache需要在对应的mapper.xml里开启缓存
<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd"> <mapper namespace="test"> <cache type="org.mybatis.caches.ehcache.EhcacheCache"/> <select id="getUser" parameterType="int" resultType="User"> select id, name, age, gmt_create gmtCreate from users where id=#{id} </select> <insert id="insertUser" parameterType="user"> <selectKey keyProperty="id" order="AFTER" resultType="java.lang.Integer"> SELECT LAST_INSERT_ID() </selectKey> insert into users(name, age, gmt_create, money) VALUE (‘xiao‘, 24, ‘1991-06-26‘, 10000) </insert> <select id="selectAny" resultType="user" parameterType="user"> select id, name, age, gmt_create gmtCreate from users <where> <if test="ids!=null"> and id in <foreach collection="ids" item="id" open="(" close=")" separator=","> #{id} </foreach> </if> </where> </select> <select id="getSome" parameterType="user" resultType="user"> select count(*) from users </select> <select id="getUserByTime" parameterType="Date" resultType="User"> select id, name, age, gmt_create gmtCreate from users <![CDATA[ where gmt_create >= #{sd} ]]> </select> <select id="getUserByWeek" resultType="User"> select id, name, age, gmt_create gmtCreate from users <![CDATA[ where gmt_create >= NOW() - interval 1 day ]]> </select> </mapper>
其中的<cache type="org.mybatis.caches.ehcache.EhcacheCache"/>即开启c3p0缓冲池
<ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="../config/ehcache.xsd"> <diskStore path="D:\develop\ehcache" /> <defaultCache maxElementsInMemory="1000" maxElementsOnDisk="10000000" eternal="false" overflowToDisk="false" timeToIdleSeconds="120" timeToLiveSeconds="120" diskExpiryThreadIntervalSeconds="120" memoryStoreEvictionPolicy="LRU"> </defaultCache> </ehcache>
9.applicationContext-service.xml
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:context="http://www.springframework.org/schema/context" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.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-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 "> <context:component-scan base-package="com.atguigu.springmvc"> <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> <bean id="userDao" class="com.atguigu.springmvc.crud.dao.UserDaoImpl"> <property name="sqlSessionFactory" ref="sqlSessionFactory" /> </bean> </beans>
springmvc扫描过的类就不需要再扫描了，防止重复初始化。
