springMVC、spring、jpa、springData整合配置

web.xml文件配置

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

            <param-name>encoding</param-name>
            <param-value>UTF-8</param-value>
        </init-param>
    </filter>
    <filter-mapping>

    </filter>

    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:com/configuration/spring.xml</param-value>
    </context-param>

        <servlet-name>dispatcher</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>
</web-app>

　　配置springMVC：扫描包，解析器，加载静态功能和注解功能

<?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-4.1.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.1.xsd">
 
    <!--自动扫描包-->
    <context:component-scan base-package="com" 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>
 
 
    <!--视图解析器-->
    <bean id="my" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/views/"/>
        <property name="suffix" value=".jsp"/>
    </bean>
 
    <!--处理静态资源-->
    <mvc:default-servlet-handler></mvc:default-servlet-handler>
    <mvc:annotation-driven></mvc:annotation-driven>
 
</beans>

　　配置spring文件：扫描包，配置dataSource，配饰japEntityFactory等等..jpa的基本配置,事务，jpa管理器,springData

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
