4.数据访问层
a.id as "id",
a.userName as "userName",
a.userPwd as "userPwd",
a.age as "age",
a.address as "address"
package com.weichai.SpringSession.dao;
import com.weichai.SpringSession.entity.User;
public interface UserDao {
public User findByUserNameAndUserPwd(String userName,String userPwd);
public User findById(Integer id);
}
5.服务层
package com.weichai.SpringSession.service;
import javax.annotation.Resource;
import org.springframework.stereotype.Service;
import com.weichai.SpringSession.dao.UserDao;
import com.weichai.SpringSession.entity.User;
@Service
public class UserService {
@Resource
private UserDao userDao;
public User findByUserNameAndUserPwd(String userName,String userPwd) {
return userDao.findByUserNameAndUserPwd(userName, userPwd);
}
public User findById(Integer id) {
return userDao.findById(id);
}
}

出现以上异常.然后就在baidu上
cmd命令打jar是如下实现：
在运行里输入cmd，利用cmd命令进入到本地的工作盘符。(如我的是D盘下的文件有此路径 D:\workspace\prpall\WEB-INF\classes)
现在是想把D:\workspace\prpall\WEB-INF\classes路径下所有的文件打包成prpall.jar。然后继续如下操作：
cd D: 回车
cd workspace/prpal

随着RESTful Web Service的流行，测试对外的Service是否满足期望也变的必要的。从Spring 3.2开始Spring了Spring Web测试框架，如果版本低于3.2，请使用spring-test-mvc项目（合并到spring3.2中了）。
Spring MVC测试框架提供了对服务器端和客户端（基于RestTemplate的客户端）提供了支持。

Thread dumps are very useful for diagnosing synchronization related problems such as deadlocks on object monitors. Ctrl-\ on Solaris/Linux or Ctrl-B
