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

http://xlaohe1.iteye.com/blog/1139028

一下代码不完整的，可参考 http://blog.csdn.net/jlh2/article/details/4807801

springmvc和hibernate的annotation集合:
首先web.xml
Xml代码

<?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_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代码

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

entity:

userdaoimpl
