ssm相对标准配置(Spring+springmvc+mybatis)

资源下载:http://download.csdn.net/detail/zhangpan_soft/9742369

最近在看一些童鞋找ssm的整合,发现,很多网上的都不尽相同,在此我提供一下springmvc的整合思路,

其实说起来是ssm的整合,倒不如说是Spring+mybatis的整合,和spring+springmvc的整合,

首先先说Spring+mybatis的整合,

对于mybatis,我们知道,连接数据库必须要连接池(数据源),所以,第一步配置连接池,mybatis是基于sqlsessionfactory的,所以要配置sqlsessionfactory,要使用mapper文件,所以要配置MapperScanner,

对于事务的控制要给Spring,所以要配置事务,基于注解开发,所以要配置注解扫描

二:Spring和springmvc的整合,基于注解开发,要配置注解扫描,对资源文件不拦截,所以配置静态资源,等等一些其他的,

最后:在web.xml中进行一系列配置,下面附上配置代码和注释,另外附上附件可以下载:

最后说一点,本文为了防止容器污染,在配置中做了特别的处理,这种处理也是Spring官方建议的处理,

spring和mybatis整合的配置,一般命名为spring-application.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:tx="http://www.springframework.org/schema/tx"       xmlns:aop="http://www.springframework.org/schema/aop"       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.xsd       http://www.springframework.org/schema/tx       http://www.springframework.org/schema/tx/spring-tx.xsd       http://www.springframework.org/schema/aop       http://www.springframework.org/schema/aop/spring-aop.xsd">    <!-- 加载小配置文件 -->    <context:property-placeholder location="classpath:db.properties"/>    <!-- 开启aop，对类代理 -->    <aop:config proxy-target-class="true"/>    <!-- 配置注解扫描,防止容器污染,排除Controller注解,切记切记 -->    <context:component-scan base-package="com.redao.manage">        <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>    </context:component-scan>    <!-- 配置DataSource(数据源,这里用的是阿里数据源) -->    <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource">        <property name="driverClassName" value="${jdbc.driver}"/>        <property name="url" value="${jdbc.url}"/>        <property name="username" value="${jdbc.username}"/>        <property name="password" value="${jdbc.password}"/>    </bean>    <!-- 配置sqlsessionFactroy -->    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">        <!--配置数据源-->        <property name="dataSource" ref="dataSource"/>        <!--配置mapper文件路径-->        <property name="mapperLocations" value="classpath:mapper/*.xml"/>        <!--配置别名所在包-->        <property name="typeAliasesPackage" value="com.redao.manage.model"/>    </bean>    <!-- mapper扫描 -->    <bean id="mapperScannerConfigurer" class="org.mybatis.spring.mapper.MapperScannerConfigurer">        <!--配置sqlsessionfactory,切记,这里不能用ref,必须用value,值为上面配置的sqlsessionfactory的值-->        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/>        <property name="basePackage" value="com.redao.manage.dao"/>    </bean>    <!-- 事务管理器 -->    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">        <!--配置数据源-->        <property name="dataSource" ref="dataSource"/>    </bean>    <!--开启注解控制事务-->    <tx:annotation-driven transaction-manager="transactionManager"/></beans>

2.spring和springmvc整合的配置,一般命名为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.xsd       http://www.springframework.org/schema/mvc       http://www.springframework.org/schema/mvc/spring-mvc.xsd">    <!-- 注解扫描,注意配置,这里只扫描Controller,防止容器污染,切记,切记,和spring-application.xml进行对比 -->    <context:component-scan base-package="com.redao.manage" use-default-filters="false">        <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>    </context:component-scan>    <!-- 配置json解析 -->    <mvc:annotation-driven conversion-service="conversionService">        <mvc:message-converters>            <bean class="com.alibaba.fastjson.support.spring.FastJsonHttpMessageConverter"/>        </mvc:message-converters>    </mvc:annotation-driven>    <!-- 添加转换器 -->    <bean id="conversionService" class="org.springframework.format.support.FormattingConversionServiceFactoryBean">        <property name="converters">            <set>                <!--这里面是我自己定义的转换器,只要实现converter接口就是转换器-->                <bean class="com.redao.manage.converter.String2Date"/>                <bean class="com.redao.manage.converter.String2Long"/>            </set>        </property>    </bean>    <!-- 解决自动添加前后缀 -->    <bean id="internalResourceViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">        <!--jsp文件防止web-inf下面,为了安全,所以,这里如此配置-->        <property name="prefix" value="/WEB-INF/"/>        <property name="suffix" value=".jsp"/>    </bean>    <!-- 全局异常处理器解析器 -->    <bean class="com.redao.manage.exception.CustomExceptionResolve"/>    <!--静态资源解析,这里用spring默认就可以-->    <mvc:default-servlet-handler/>    <!-- 文件上传 -->    <bean id="multipartResolver"          class="org.springframework.web.multipart.commons.CommonsMultipartResolver">        <!-- 设置上传文件的最大尺寸为5MB -->        <property name="maxUploadSize">            <value>52428800</value>        </property>        <!--设置编码-->        <property name="defaultEncoding" value="UTF-8"></property>        <!--设置临时文件存放路径-->        <property name="uploadTempDir" value="fileUpload/temp"></property>    </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"         xsi:schemaLocation="http://java.sun.com/xml/ns/javaee         http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"         id="WebApp_ID" version="2.5">  <!-- 配置字符编码,如下除了UTF-8可以变,其他不变, -->  <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>  </filter>  <filter-mapping>    <filter-name>encodingFilter</filter-name>    <url-pattern>/*</url-pattern>  </filter-mapping>  <!-- 监听器,加载application配置文件 -->  <listener>    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>  </listener>  <context-param>    <param-name>contextConfigLocation</param-name>    <param-value>classpath:spring/spring-application.xml</param-value>  </context-param>  <!--配置DispatcherServlet-->  <servlet>    <servlet-name>DispatcherServlet</servlet-name>    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>    <!--配置springmvc.xml的配置文件-->    <init-param>      <param-name>contextConfigLocation</param-name>      <param-value>classpath:spring/springmvc.xml</param-value>    </init-param>    <!--设为1代表优先启动,0代表随机启动,大于0的整数优先级随数值的递增而减小(反比)-->    <load-on-startup>1</load-on-startup>  </servlet>  <!--这里配置url为/,可以更好的使用restfull风格 -->  <servlet-mapping>    <servlet-name>DispatcherServlet</servlet-name>    <url-pattern>/</url-pattern>  </servlet-mapping>  <welcome-file-list>    <welcome-file>index.jsp</welcome-file>  </welcome-file-list></web-app>
