spring3.1 mvc+spring

</beans> </pre>

spring也支持了jndi（這里就不再講解jndi了）：

<bean id="dataSource" class="org.springframework.jndi.JndiObjectFactoryBean">
        <property name="jndiName">
            <value>myTestDataSource</value>
    </property>
    <!-- 如果你不想使用 'java:comp/env/'前綴的話請設置下面的值為true, 默認值為false -->
    <property name="resourceRef">
        <value>false</value>
    </property>
</bean>

 好了到這里我們的配置基本上就完了。。在編寫業務代碼前還有一些知識需要大家去學習一下:

常用注解：

package com.springdemo.module.usermgr.controller;

import java.util.List;
import javax.servlet.http.HttpSession;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.servlet.ModelAndView;
import com.springdemo.core.ActionException;
import com.springdemo.core.BaseContoller;
import com.springdemo.core.ServiceException;
import com.springdemo.module.usermgr.service.UserMgrService;
import com.springdemo.module.usermgr.vo.SUser;
/**

@Controller
public class UserLoginMgr extends BaseContoller{
 @Autowired
 private UserMgrService userMgrService;
@RequestMapping(value="saveLogin.htm",method=RequestMethod.POST)
 public ModelAndView saveLogin(HttpSession session,SUser user,ModelMap modelMap){

 if(user!=null){
     String userName = user.getUserName();
     try {
         SUser dbuser = userMgrService.getUserByUserName(userName);
         if(dbuser==null){
             //成功后重定向的歡迎界面，防止重復提交
             return new ModelAndView("login",COMMON_FAIL_ALERT_KEY,"用戶不存在!");
         }
         if(!dbuser.getPwd().equals(user.getPwd())){

             return new ModelAndView("login",COMMON_FAIL_ALERT_KEY,"密碼錯誤!");
         }

         session.setAttribute(USER_SESSION_KEY, dbuser);
     } catch (ServiceException e) {
         e.printStackTrace();
     }
 }
 //成功后重定向的歡迎界面，防止重復提交
 return new ModelAndView("redirect:login_succ.htm");

}
 //獲取
 @RequestMapping(value="get/{id}.htm",method=RequestMethod.GET)
 public ModelAndView get(@PathVariable Integer id) throws Exception{

 SUser sUser = userMgrService.getUserById(id);
  if(sUser==null){
     throw  new ActionException("用戶["+id+"]不存在!");
  }
 return new ModelAndView("user_detail","user",sUser);

}
 //列表
 @RequestMapping(value="list.htm",method=RequestMethod.GET)
 public ModelAndView list() throws ServiceException{

 List<SUser> users = userMgrService.getUsers();
 return new ModelAndView("/test/user_list","users",users);

}
 //注冊成功
 @RequestMapping(value="login_succ.htm")
 public  String signuoSucc(HttpSession session,ModelMap map){

 SUser user = (SUser) session.getAttribute(USER_SESSION_KEY);
 if(user==null){
     return "redirect:login.htm";
 }
 map.put("user", user);
 return "index";

}
 @RequestMapping("logout.htm")
 public String logout(HttpSession session){

 session.invalidate();
 return "redirect:login.htm";

}
 //首頁
 @RequestMapping(value="index.htm")
 public  String index(){

 return "forward:login_succ.htm";

}
}</pre> 


service代碼：



 
package com.springdemo.module.usermgr.service;



import java.util.Date;
import java.util.List;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.dao.EmptyResultDataAccessException;
import org.springframework.stereotype.Service;
import com.springdemo.core.BaseService;
import com.springdemo.core.ServiceException;
import com.springdemo.module.usermgr.dao.UserMgrDao;
import com.springdemo.module.usermgr.vo.SUser;
@Service("userMgrService")
public class UserMgrService extends BaseService{

@Autowired
private UserMgrDao userMgrDao;
public void signUp(SUser user) throws ServiceException{
    try {
        user.setSignUpTime(new Date());
        userMgrDao.addUser(user);
    } catch (Exception e) {
        throw new ServiceException("注冊失敗", e);
    }

}
public SUser getUserById(Integer id) throws ServiceException{
    try {
        return userMgrDao.getUserByColunm("id",id);
    } catch (Exception e) {
        throw new ServiceException("獲取失敗", e);
    }
}
public List<SUser> getUsers() throws ServiceException{
    try {
        return userMgrDao.getUsers();
    } catch (Exception e) {
        throw new ServiceException("獲取失敗", e);
    }
}
public SUser getUserByUserName(String userName) throws ServiceException {
    try {
        return userMgrDao.getUserByColunm("userName",userName);
    } catch (Exception e) {
        if(e instanceof EmptyResultDataAccessException){
            return null;
        }
        throw new ServiceException("獲取失敗", e);
    }
}

}</pre>

model 代碼：

package com.springdemo.module.usermgr.dao;

import java.util.List;
import org.springframework.jdbc.core.BeanPropertyRowMapper;
import org.springframework.stereotype.Repository;
import com.springdemo.core.BaseDao;
import com.springdemo.module.usermgr.vo.SUser;
@Repository("userMgrDao")
@SuppressWarnings("unchecked")
public class UserMgrDao extends BaseDao{

public SUser addUser(final SUser sUser){
      sUser.setId(super.saveAndReturnKey(sUser).intValue());
      return sUser; 
}

public List<SUser> getUsers() {
    return getJdbcTemplate().query("select *  from suser", new BeanPropertyRowMapper(SUser.class));
}
public SUser getUserByColunm(String columnName, Object value) {
    return getJdbcTemplate().queryForObject("select *  from suser where "+columnName+"=?", new BeanPropertyRowMapper(SUser.class),value);
}

}</pre>

jap 代碼：

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
  <body>
