web配置

1、首先配置spring  启动IOC容器的Listener

<!-- Spring监听器 --> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener>

2、配置前端dispatchServlet

<servlet> <servlet-name>spring</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <!-- 此处指向的的是SpringMVC的配置文件 --> <param-value>classpath:META-INF/spring-mvc.xml</param-value> </init-param> <!--配置容器在启动的时候就加载这个servlet并实例化--> <load-on-startup>1</load-on-startup> </servlet>         <servlet-mapping> <servlet-name>spring</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping>

3、编码格式

<!-- 字符集过滤 --> <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> <filter-mapping> <filter-name>encodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping>

这里需要注意的是编码的过滤器最好应该配在所有的过滤器前，否则可能无效

springMVC的配置文件：springDispatchServlet配置文件

1、设置自动扫描的包

<!-- 启动注解驱动的spring MVC功能,注册请求url和注解POJO类方法的映射--> <mvc:annotation-driven /> 　　　 <context:component-scan base-package="com.test" />

2、配置视图解析器

<!-- 对模型视图名称的解析,在请求时模型视图名称添加前后缀 --> <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="viewClass" value="org.springframework.web.servlet.view.JstlView" /> <property name="prefix" value="views/" /> <!-- 前缀 --> <property name="suffix" value=".jsp" /> <!-- 后缀 --> </bean>

3、处理MVC静态资源的

<!--这里是对静态资源的映射--> <mvc:resources mapping="/js/**" location="/resources/js/" /> <mvc:resources mapping="/css/**" location="/resources/css/" /> <mvc:resources mapping="/img/**" location="/resources/img/" />

spring配置文件applicationContext.xml

1、配置自动扫描包 <!-- 自动扫描 --> <context:component-scan base-package="com.test.*"> <!-- 扫描时跳过 @Controller 注解的JAVA类（控制器） --> <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/> </context:component-scan> 2、配置数据源 <!-- 配置数据源 -->      <context:property-placeholder location="classpath:db.properties"/>        <bean id="dataSource"          class="com.mchange.v2.c3p0.ComboPooledDataSource">          <property name="user" value="${jdbc.user}"></property>            <property name="password" value="${jdbc.password}"></property>            <property name="driverClass" value="${jdbc.driverClass}"></property>              <property name="jdbcUrl" value="${jdbc.jdbcUrl}"></property>                        <!-- 配置其他属性 -->      </bean>   3、配置jpa  <bean id="entityManagerFactory"          class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">          <property name="dataSource" ref="dataSource"></property>          <property name="jpaVendorAdapter">              <bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter"></bean>          </property>             <property name="packagesToScan" value="com.atguigu.sssp"></property>          <property name="jpaProperties">              <props>                  <prop key="hibernate.ejb.naming_strategy">org.hibernate.cfg.ImprovedNamingStrategy</prop>                  <prop key="hibernate.hbm2ddl.auto">update</prop>                  <prop key="hibernate.show_sql">true</prop>                  <prop key="hibernate.format_sql">true</prop>                  <prop key="hibernate.dialect">org.hibernate.dialect.MySQL5InnoDBDialect</prop>                                    <prop key="hibernate.cache.use_second_level_cache">true</prop>                  <prop key="hibernate.cache.region.factory_class">org.hibernate.cache.ehcache.EhCacheRegionFactory</prop>                  <prop key="hibernate.cache.use_query_cache">true</prop>              </props>          </property>          <property name="sharedCacheMode" value="ENABLE_SELECTIVE"></property>      </bean>   props里面属性

jdbc.user=root  jdbc.password=1230  jdbc.driverClass=com.mysql.jdbc.Driver  jdbc.jdbcUrl=jdbc:mysql:///spring  

4、配置事务

 <!-- 配置事务 -->  

  <bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager">                         <property name="entityManagerFactory" ref="entityManagerFactory"></property>     

               </bean>  

5、配置springData

 <!-- 配置 SpringData -->      <jpa:repositories base-package="com.atguigu.sssp"          entity-manager-factory-ref="entityManagerFactory"></jpa:repositories>
