首先是web包下属于的control层的类UserController，这相当于Struts中的Action，是重要的类：
[java] package com.tgb.web;
import java.io.IOException;
import java.io.PrintWriter;
import javax.annotation.Resource;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import com.tgb.entity.User;
import com.tgb.manager.UserManager;
@Controller
@RequestMapping("/user")
public class UserController {
@Resource(name="userManager")
private UserManager userManager;
@RequestMapping("/getAllUser")
public String getAllUser(HttpServletRequest request){
request.setAttribute("userList", userManager.getAllUser());
return "/index";
}
@RequestMapping("/getUser")
public String getUser(String id,HttpServletRequest request){
request.setAttribute("user", userManager.getUser(id));
return "/editUser";
}
@RequestMapping("/toAddUser")
public String toAddUser(){
return "/addUser";
}
@RequestMapping("/addUser")
public String addUser(User user,HttpServletRequest request){
userManager.addUser(user);
return "redirect:/user/getAllUser";
}
@RequestMapping("/delUser")
public void delUser(String id,HttpServletResponse response){
String result = "{\"result\":\"error\"}";
if(userManager.delUser(id)){
result = "{\"result\":\"success\"}";
}
response.setContentType("application/json");
try {
PrintWriter out = response.getWriter();
out.write(result);
} catch (IOException e) {
e.printStackTrace();
}
}
@RequestMapping("/updateUser")
public String updateUser(User user,HttpServletRequest request){
if(userManager.updateUser(user)){
user = userManager.getUser(user.getId());
request.setAttribute("user", user);
return "redirect:/user/getAllUser";
}else{
return "/error";
}
}
}
