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"?>

    <bean id="transactionManager"

entity:
Java代码

    public void setAge(Integer age) {  
        this.age = age;  
    }  
      
      
}



userdaoimpl
Java代码  
package org.xlaohe1.dao.impl;  
  
import java.util.List;  
  
import org.springframework.orm.hibernate3.support.HibernateDaoSupport;  
import org.springframework.stereotype.Repository;  
import org.xlaohe1.dao.IUserDao;  
import org.xlaohe1.model.User;  
  
@Repository  
public class UserDaoImpl extends HibernateDaoSupport implements IUserDao {  
  
    @SuppressWarnings("unchecked")  
    @Override  
    public List<User> findAllUsers() {  
        String hql = "FROM User";  
        return getHibernateTemplate().find(hql);  
    }  
  
}



userserviceimpl
Java代码  
package org.xlaohe1.service.impl;  
  
import java.util.List;  
  
import org.springframework.beans.factory.annotation.Autowired;  
import org.springframework.stereotype.Service;  
import org.springframework.transaction.annotation.Transactional;  
import org.xlaohe1.dao.IUserDao;  
import org.xlaohe1.model.User;  
import org.xlaohe1.service.IUserService;  
  
@Service @Transactional  
public class UserServiceImpl implements IUserService {  
      
    @Autowired IUserDao userDao;  
  
    @Override

    public List<User> findAllUsers() {  
        return userDao.findAllUsers();  
    }  
}



usercontroller
Java代码  
package org.xlaohe1.web;  
  
import java.util.List;  
  
import javax.servlet.http.HttpServletRequest;  
import javax.servlet.http.HttpServletResponse;  
  
import org.springframework.beans.factory.annotation.Autowired;  
import org.springframework.stereotype.Controller;  
import org.springframework.ui.ModelMap;  
import org.springframework.web.bind.annotation.RequestMapping;  
import org.springframework.web.servlet.ModelAndView;  
import org.xlaohe1.model.User;  
import org.xlaohe1.service.IUserService;  
  
@Controller  
public class UserController {  
    @Autowired  
    IUserService userService;  
  
    public UserController() {  
    }  
  
    @RequestMapping(value = "/show")  
    public ModelAndView myMethod(HttpServletRequest request,  
            HttpServletResponse response, ModelMap modelMap) throws Exception {  
        List<User> ulst = userService.findAllUsers();  
        modelMap.put("users", ulst);  
        return new ModelAndView("showUser", modelMap);  
  
    }  
      
    @RequestMapping(value = "/t")  
    public ModelAndView t() {  
        return new ModelAndView("t");  
    }  
  
}

  


<context:annotation-config />这个配置告诉springmvc,springmvc相关的bean中使用注解来进行表示

<context:component-scan base-package="com.jlh2.study.web.module"/>这个配置告诉springmvc对com.jlh2.study.web.module进行扫描，并创建其中的javaBe an并注入到spring容器中。

<bean class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping" /> 启动springmvc的注解映射功能

<bean class="org.springframework.web.servlet.mvc.support.ControllerClassNameHandlerMapping" /> 自动将访问url映射到同名的Controller上面

<bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"/> 启动springmvc的注解功能
