java - 如何在端点函数体内检索请求方法？

Question

假设我有一个 Controller ，这是我的端点。我该如何做与我体内相似的事情？

@RequestMapping(path = "/path/**", consumes = "application/json")
@ResponseStatus(HttpStatus.OK)
public <T> ResponseEntity<T> getResponse(@PathVariable UUID varId) {
   HttpMethod httpMethod = foo();
   if (httpMethod == httpMethod.GET) {
      //do something
   }
}

有办法做到这一点吗？

您可以将 HttpServletRequest 的实例注入(inject)到您的方法中。

@RequestMapping(path = "/path/**", consumes = "application/json")
@ResponseStatus(HttpStatus.OK)
public <T> ResponseEntity<T> getResponse(@PathVariable UUID varId, 
                                         HttpServletRequest httpServletRequest) {
   HttpMethod httpMethod = HttpMethod.valueOf(httpServletRequest.getMethod());
   if (httpMethod == httpMethod.GET) {
      //do something
   }
}

请注意@GetMapping , @PostMapping和 @RequestMapping(method="...") - 您可以指定给定端点允许使用哪些 HTTP 方法。
