我可以在 Spring Boot 中使用请求正文执行 GET 吗？

Question

I'm using Spring Boot and Spring MVC and I need to make a GET with a request body. Is this possible?

I tried this but it's not working. I get 404.

@RestController
@RequestMapping("/api")
public class HomeController {

    @GetMapping("/v1/foo")
    public ApiRes postBody(@RequestBody ApiReq apiReq) {
        ...
    }
}

Answer 1

Technically it is possible but it is against the HTTP API Design Guidelines. Request-Bodys should only be used for POST or PUT.
