如何创建 Spring Boot REST 服务“类型：POST”？

Question

我是 Spring Boot 的初学者，我正在尝试创建添加两个数字的 REST 端点（类型：POST），所以任何人都可以帮助我并告诉我代码中的问题在哪里？

package demo.controller;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.web.bind.annotation.RequestBody;

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

import org.springframework.web.bind.annotation.RequestMethod;

import org.springframework.web.bind.annotation.RestController;

import demo.service.ServiceAdding;

@RestController

public class DemoController {

    @Autowired

    private ServiceAdding ServiceAdding;

    @RequestMapping(value="/getNumbers", method=RequestMethod.GET)

    public ServiceAdding getNumbers() {

        ServiceAdding.setNumber1(1);

        ServiceAdding.setNumber2(3);

        return ServiceAdding;

    }

        @RequestMapping(value="/postNumbers", method=RequestMethod.POST)

        public int postNumbers (@RequestBody final ServiceAdding ServiceAdding ) {

            int sum = ServiceAdding.getNumber1() + ServiceAdding.getNumber2();

            return sum;

        }

    }

Answer 1

尝试使用 @PostMapping 而不是 @RequestMapping    @PostMapping(value = "postNumbers")    public int postNumbers(...){      ...    }

Answer 2

你有什么错误？也可以尝试向 restController 添加一个值？@RestController(value="api/v1")@RequestMapping(value = "/getNumbers, method = RequestMethod.GET, produces = "application/json")你也可以使用@GetMapping, @PostMapping等
