Spring3.0MVC和Hibernate基于annotation注解的整合

springmvc和hibernate的annotation集合:
首先web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www./2001/XMLSchema-instance" xmlns="http://java./xml/ns/javaee" xmlns:web="http://java./xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java./xml/ns/javaee http://java./xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">
  <display-name>hibernateAspringmvc</display-name>
  <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath*:applicationContext*.xml</param-value>
    </context-param>
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>

    <servlet>
        <!-- this is 'spring' name for your spring-servlet.xml -->
        <servlet-name>spring</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>

    <servlet-mapping>
        <servlet-name>spring</servlet-name>
        <url-pattern>*.xl</url-pattern>
    </servlet-mapping>
  <welcome-file-list>
    <welcome-file>index.html</welcome-file>
    <welcome-file>index.htm</welcome-file>
    <welcome-file>index.jsp</welcome-file>
    <welcome-file>default.html</welcome-file>
    <welcome-file>default.htm</welcome-file>
    <welcome-file>default.jsp</welcome-file>
  </welcome-file-list>
</web-app>

然后是applicationContext.xml

<?xml version="1.0" encoding="UTF-8"?>
