我试图建立一个简单的Restful Web服务，该服务根据Accept标头返回JSON或XML。我正在使用Spring，Maven和WebLogic
Server。我从这篇文章http://software.sawano.se/2012/03/combining-json-and-xml-in-
restful-web.html中获取了示例，并尝试对其进行改进。GET和DELETE都适用于JSON和XML。但是PUT和POST给出“
405不允许的方法”错误。我正在尝试使用Chrome Extension Advanced Rest Client对此进行测试。下面是Response标头。

我给的请求正文如下：

}

我的控制器类如下所示：

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.http.HttpStatus;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.*;

import java.util.HashSet;
import java.util.Set;

@Controller
@RequestMapping("/users")
public class RESTController {
Userlist obj2;
boolean flag=false;
private Logger logger = LoggerFactory.getLogger(getClass());

@RequestMapping(value = "/{id}",method = RequestMethod.GET)
@ResponseBody
public User getUser(@PathVariable int id, @RequestHeader("Accept") String acceptHeader) {
    User temp = new User();
    if(obj2==null)
    {
        temp= new User(0, "Null");
    }
    else   {
        Set<User> set1= obj2.getUsers();
        for(User a:set1)
        {
            if(id==a.getId()) temp=a;
        }
      }
    logger.trace("Serving resource for Accept header: {}", acceptHeader);
    return temp;
}

@RequestMapping(value="",method = RequestMethod.GET)
@ResponseBody
public Userlist getUsers(){
    if(flag==false){
    User new1=new User(1,"Rob");
    User new2=new User(2,"VAN");
    User new3=new User(3,"DAM");
    User new4=new User(4,"Helio");
 Set<User> obj1 =new HashSet<User>();
    obj1.add(new1);
    obj1.add(new2);
    obj1.add(new3);
    obj1.add(new4);
    obj2=new Userlist(obj1);
    flag=true;
    }
    return obj2;
}

@RequestMapping(value="/{id}",method = RequestMethod.DELETE)
@ResponseStatus(HttpStatus.OK)
public void deleteUser(@PathVariable int id){
    Set<User> set1= obj2.getUsers();
   for(User a:set1)
    {
        if(id==a.getId()) set1.remove(a);
     }
    Userlist obj3=new Userlist(set1);
    obj2=obj3;
    //return obj3;
}

@RequestMapping(value="/{id}",method = RequestMethod.PUT, consumes = "Application/json")
@ResponseStatus(HttpStatus.OK)
public void updateUser(@PathVariable int id, @RequestBody User temp){
    System.out.println("Inside the put function");
        if(temp==null){System.out.println("This is a Null for PUT");}
 }
}

目前，我在PUT中没有任何内容。
