java - Spring MVC : HTTP 405 - Request method 'GET' not supported when making POST request

Question

刚刚启动了一个默认的 Spring MVC 项目，但我无法让 POST 请求处理程序工作。这是我的 Controller :

package com.myapp.controller;

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

import com.myapp.domain.Response;

@Controller
public class MyAppController {

    @RequestMapping(value = "/", method = RequestMethod.POST)
    @ResponseBody
    public Response query() {
        return new Response();
    }
}

Response 是一个像这样的简单 POJO:

package com.myapp.domain;

public class Response {

    private String text;
    private String ref;

    public Response() {}

    public String getText() {
        return text;
    }

    public void setText(String text) {
        this.text = text;
    }

    public String getRef() {
        return ref;
    }

    public void setRef(String ref) {
        this.ref = ref;
    }
}

Jackson 在 pom.xml 中声明为依赖项。

当我发出 POST 请求(通过 Postman)时，tomcat 返回 HTTP 405 - Request method 'GET' not supported。有什么配置可以让tomcat响应POST请求吗？

Answer 1

尝试使用

curl -X POST http://localhost:8080

检查。

或者尝试为您的测试设置另一个 url，而不是 '/'。
