    每日一道理
有一首诗最为动人，那就是青春；有一段人生最美丽，那就是青春；有一道风景最为亮丽，那就是青春。青春，不要说已疲惫，也许你的幻想曾被现实无情毁灭，也许你的追求毫无结果，但你应该相信，没有寒风的洗礼，哪来万紫千红的春天，没有心的耕耘，哪有累累硕果？

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

import com.jialin.entity.User;
import com.jialin.service.IUserManager;

@Controller //相似Struts的Action
@RequestMapping("/user")
public class UserController {

@Resource(name="userManager") // 获得spring配置文件中bean的id为userManager的，并注入
private IUserManager userManager;

@RequestMapping("/addUser") // 请求url地址映射，相似Struts的action-mapping
public String addUser(User user){
if(userManager.addUser(user))
{
// 重定向
return "redirect:/user/getAllUser";
}else
{
return "/fail";
}

}

@RequestMapping("/updateUser")
public String updateUser(User user,HttpServletRequest request){
if (userManager.updateUser(user))
{
user = userManager.getOneUser(user);
request.setAttribute("user", user);
return "/UserEdit";
}else
{
return "/fail";
}

}

@RequestMapping("/delUser")
public void delUser(User user,HttpServletResponse response){
String result = "{\"result\":\"error\"}";

if(userManager.delUser(user)){
result = "{\"result\":\"success\"}";
}
PrintWriter out = null;
response.setContentType("application/json");

try {
out = response.getWriter();
out.write(result);
} catch (IOException e) {
e.printStackTrace();
}

}
@RequestMapping("/toAddUser")
public String toAddUser(){
return "/UserAdd";
}

@RequestMapping("/toUpdateUser")
public String toUpdateUser(User user,HttpServletRequest request){
User user1=userManager.getOneUser(user);

request.setAttribute("user1", user1);

return "/UserEdit";
}

@RequestMapping("/getAllUser")
public String getAllUser(HttpServletRequest request){

List userList=userManager.getAllUser();

request.setAttribute("userlist", userList);

}

}

文章结束给大家分享下程序员的一些笑话语录：

Borland说我很有前途，Sun笑了；Sun说我很有钱，IBM笑了；IBM说我很专业，Sybase笑了；Sybase说我数据库很牛，Oracle笑了；Oracle说我是开放的，Linux笑了；Linux说我要打败Unix，微软笑了；微软说我的系统很稳定，我们都笑了。
