java - 让 JSON Post 在 Spring Boot 中工作

Question

我正在尝试使用 JSON 对我正在运行的 Spring Boot 应用程序进行 POST 调用，每次进行 POST 调用时都会收到以下错误

Request method 'POST' not supported

这是我的 Controller 的基本布局，

@RestController
public class MessagesController {

    @RequestMapping(value = "/messages", method = RequestMethod.POST)
    public @ResponseBody Answer processMessage(@RequestBody Message message) throws Exception{
        System.out.println("HERE");

        Answer a = new Answer(5);

        return a;
    }

    @ExceptionHandler
    void handleException(Exception e, HttpServletResponse response) throws IOException {
        response.sendError(HttpStatus.CONFLICT.value());
    }
}

Message 和 Answer 是 POJO

public class Message implements Serializable{
    private int id;
    private int description;

    public int getId() {
        return id;
    }
    public void setId(int id) {
        this.id = id;
    }
    public String getDescription() {
        return description;
    }
    public void setDescription(String description) {
        this.description= description;
    }
}

public class Answer implements Serializable{
    private int answer;

    public Answer(int answer){
        this.answer = answer;
    }

    public int getAnswer() {
        return answer;
    }

    public void setAnswer(int answer) {
        this.answer = answer;
    }
}

我希望能够将 JSON 发布到我的 Controller ，然后接收返回的 JSON 消息。我怎样才能让它工作而不出现错误？我通过 SoapUI 发布到 http://localhost:8080/messages

Answer 1

这就是我的想法:
描述的类型不应该是String而不是int？

private int description;
public String getDescription() {
    return description;
}
public void setDescription(String description) {
    this.description= description;
}

您的帖子 json 应该是:(假设 id 是整数，描述是字符串)

{"id": 1, "descripion":"Test message"}

尝试像这样转动你的 Rest Controller :

@RestController
@RequestMapping("messages")
public class MessagesController {
    @RequestMapping(method = RequestMethod.POST)
    public Answer processMessage(@RequestBody Message message) throws Exception{
