http请求body无法获取

Question

请问：我有一个get方法，在postman中可以获取到body。但是用另外一个方法向这个url发送请求时，无法接收到body是为什么.

  @GetMapping ("/ip")
//    , @RequestBody Object body
    public Object getIp( HttpServletRequest request,@RequestBody Object body ) throws IOException {
        System.out.println( body );
         return body；
    }

@GetMapping("/submitIp")
    public String getIpByThisIp(HttpServletRequest request){
        String authorization = request.getHeader( "authorization" );
        String url = "http://localhost:30999/httpbin/ip";
        HttpHeaders headers = new HttpHeaders();
        headers.setContentType( MediaType.APPLICATION_JSON );
        String jsonAuthorization = JSONObject.toJSONString( authorization );
        HttpEntity entity = new HttpEntity( jsonAuthorization,headers );
        HttpMethod  method = HttpMethod.GET;
        ResponseEntity< String > exchange = restTemplate.exchange( url, method, entity, String.class );
        return "ok";
    }

postman没有限制get请求还能发送body数据，但是java的客户端和js基本都限制了，你发送get请求就会丢弃body，发json就别用get
