spring3mvc+mybatis 环境搭建

1.配置applicationContext配置文件

<?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:p="http://www.springframework.org/schema/p"        xmlns:tx="http://www.springframework.org/schema/tx"        xsi:schemaLocation="http://www.springframework.org/schema/beans                 http://www.springframework.org/schema/beans/spring-beans-3.1.xsd                http://www.springframework.org/schema/context                 http://www.springframework.org/schema/context/spring-context-3.1.xsd                http://www.springframework.org/schema/tx                 http://www.springframework.org/schema/tx/spring-tx-3.1.xsd"                 default-autowire="byName">         <!-- 扫描 com.eightspace.baccy包下的带注解的组件-->    <context:component-scan base-package="app/manage"/>        <!-- 配置数据源，jdbc.pool数据库连接池 -->    <bean id="abstractDataSource" class="org.apache.tomcat.jdbc.pool.DataSource">        <property name="driverClassName" value="org.postgresql.Driver" />        <property name="testWhileIdle" value="true" />        <property name="testOnBorrow" value="true" />        <property name="testOnReturn" value="false" />        <property name="validationQuery" value="SELECT 1" />        <property name="validationInterval" value="30000" />        <property name="timeBetweenEvictionRunsMillis" value="30000" />        <property name="maxActive" value="50" />        <property name="minIdle" value="10" />        <property name="maxIdle" value="30" />        <property name="maxWait" value="3000" />        <property name="initialSize" value="5" />        <property name="removeAbandonedTimeout" value="600" />        <property name="removeAbandoned" value="false" />        <property name="logAbandoned" value="true" />        <property name="minEvictableIdleTimeMillis" value="30000" />        <property name="jmxEnabled" value="true" />        <property name="jdbcInterceptors" value="org.apache.tomcat.jdbc.pool.interceptor.ConnectionState;org.apache.tomcat.jdbc.pool.interceptor.StatementFinalizer" />          <property name="url" value="jdbc:postgresql://127.0.0.1/database" />             <property name="username" value="database" />        <property name="password" value="123456" />    </bean>    <!-- Spring整合Mybatis：创建 sqlSessionFactory-->    <bean id="sqlSessionFactory"       class="org.mybatis.spring.SqlSessionFactoryBean"      p:dataSource-ref="abstractDataSource"      p:configLocation="classpath:SqlMapConfig.xml"      p:mapperLocations="classpath:app/db/sql/*.xml"/>    <!-- 定义Mybatis模板 -->    <bean id="sqlMapClientTemplate" class="org.mybatis.spring.SqlSessionTemplate">       <constructor-arg ref="sqlSessionFactory"/>    </bean>          <!-- 开启事务（基于注解） -->    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">        <property name="dataSource" ref="abstractDataSource"/>    </bean>        <!--spring容器启动时启动类 -->      <bean id="setup" class="com.eightspace.baccy.apps.Setup" init-method="init" destroy-method="destroy" />     </beans>

 
2.配置dispatcher-servlet.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:aop="http://www.springframework.org/schema/aop"xsi:schemaLocation="http://www.springframework.org/schema/beans           http://www.springframework.org/schema/beans/spring-beans-3.1.xsd                             http://www.springframework.org/schema/context                            http://www.springframework.org/schema/context/spring-context-3.1.xsd                           http://www.springframework.org/schema/aop                            http://www.springframework.org/schema/aop/spring-aop-3.1.xsd"><context:component-scan base-package="app/manage"><context:exclude-filter type="annotation"expression="org.springframework.stereotype.Service" /></context:component-scan>         <span style="color: rgb(51, 51, 51); font-family: Tahoma, 'Microsoft Yahei'; font-size: 14px; line-height: 26px;"><!-- 对模型视图名称的解析，即在模型视图名称添加前后缀 -->   </span><bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"p:prefix="/page/" p:suffix=".jsp" /> <!-- 视图文件的前缀和后缀 -->    <!-- view是用什么显示，这里是jsp，还可以用velocity之类的 -->  

           <!--支持页面上传,可添加属性  maxUploadSize 限制大小 --><bean id="multipartResolver"class="org.springframework.web.multipart.commons.CommonsMultipartResolver"

p:defaultEncoding="UTF-8" />             <!-- 启动Spring MVC的注解功能，完成请求和注解POJO的映射 --> <bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"><property name="messageConverters"><list><ref bean="mappingJacksonHttpMessageConverter" /></list></property></bean>

           <!-- 用于将对象转换为 JSON--> <bean id="mappingJacksonHttpMessageConverter"class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter"><property name="supportedMediaTypes" value="application/json" /></bean> </beans>                

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_3_0.xsd" id="WebApp_ID" version="3.0"> <display-name>projectName</display-name> <welcome-file-list>   <welcome-file>login.jsp</welcome-file> </welcome-file-list> <!-- context-param <span style="font-family: Arial; font-size: 14px; line-height: 26px;">该Listener指定要加载的xml</span>--><context-param><param-name>contextConfigLocation</param-name><param-value>classpath:applicationContext.xml</param-value></context-param>  <!-- listener -->    <listener>   <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class></listener><listener><listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class></listener><!-- servlet配置 --><servlet><servlet-name>dispatcher</servlet-name><servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class></servlet><servlet-mapping><servlet-name>dispatcher</servlet-name><url-pattern>*.do</url-pattern></servlet-mapping><!-- 过滤器配置 --><!-- 编码utf-8 --><filter><filter-name>encodingFilter</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><!-- 页面cookie验证 --><filter><filter-name>pageFilter</filter-name><filter-class>app.core.PageFilter</filter-class></filter><filter-mapping><filter-name>pageFilter</filter-name><url-pattern>/page/*</url-pattern></filter-mapping></web-app>

4.添加SqlMapConfig.xml文件

<?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="lazyLoadingEnabled" value="false" /></settings></configuration>

5.添加需要jar包
