@FeignClient 将@GetMapping 与@RequestBody 强制为POST

Question

我有以下带有 GET 方法的 REST 控制器，该方法具有 BODY，适用于测试和邮递员

@RestController
@RequestMapping(value = "/xxx")
public class Controller {
    @GetMapping({"/find"})
    public LocalDateTime findMax(@RequestBody List<ObjectId> ids) {
        //return sth   
    }
}

但是使用FeignClient调用服务时，会生成一个POST请求（忽略@GetMapping注解）

@FeignClient
public interface CoveragesServiceResource extends CoveragesService {
    @GetMapping({"/find"})
    LocalDateTime findMax(@RequestBody List<ObjectId> ids);
}

出现错误：

Request method 'POST' not supported

Answer 1

GET 请求在技术上可以有正文，但正文应该没有意义，因为 explained in this answer. You might be able to declare a GET endpoint with a body but some network libraries and tools will simply not support it e.g. Jersey can be configured to allow it but RESTEasy can't 。

建议将 /find 声明为 POST 或不使用 @RequestBody。

@FeignClient 将@GetMapping 与@RequestBody 强制为POST

@FeignClient forces @GetMapping with @RequestBody to POST
