java - PostMapping Service Rest with Spring boot错误请求方法 'POST'不支持

Question

我没有找出问题所在。

Controller

@RestController("/api")
public class CoordenadaController {

    @Autowired private RepositorioCoordenada repositorioCoordenada;

    @PostMapping("/salvar")
    public void save(String nome, int coordenadaX, int coordenadaY) {
        this.repositorioCoordenada.save(new Coordenada(nome, coordenadaX, coordenadaY));
        System.out.println("Salvou.....");
    }
}

PostMan 客户端

url localhost:8080/api/salvar?nome=Igreja&coordenadaX=10&coordenadaY=20

记录 PostMan 客户端错误

{
  "timestamp": 1493257315171,
  "status": 405,
  "error": "Method Not Allowed",
  "exception": "org.springframework.web.HttpRequestMethodNotSupportedException",
  "message": "Request method 'POST' not supported",
  "path": "/api/salvar"
}

Spring 日志错误

Request method 'POST' not supported

如果您删除@RestController中的/api，则使用@Post注释的方法可以工作

localhost:8080/salvar?nome=Igreja&coordenadaX=10&coordenadaY=20

Answer 1

您将 POST 与 GET 混合在一起。如果你想进行 POST 操作，请执行以下操作:

@RestController("/api")
public class CoordenadaController {

@Autowired private RepositorioCoordenada repositorioCoordenada;

@PostMapping("/salvar")
public void save(@RequestBody Payload payload) {
    this.repositorioCoordenada.save(new Coordenada(payload.nome, payload.coordenadaX, payload.coordenadaY));
    System.out.println("Salvou.....");
}

}

public class Payload{
String nome, int coordenadaX, int coordenadaY

//getters & setters
}

然后相应地使用postmant:使用post方法，创建一个json负载并将其添加到Body部分

json 负载:

{
    "nome": "bla bla",
    "coordenadaX": "1",
    "coordenadaY": "2"
}
