Java ResponseEntity.控制器截断响应的JSON部分

我有一个控制器，它使用RestTemplate向外部API发送请求并获取数据 struct .它应该返回这个 struct ，但在使用我的控制器时，有时会丢弃JSON响应的结尾.

我try 定制RestTemplate并增加应用程序中的响应大小.yaml

我的控制器:

    @GetMapping(value = "/weather/lat={lat}&lon={lon}")
    @Cacheable(value = "root", key = "{#lat , #lon}")
    public ResponseEntity<Root> getWeather(@PathVariable("lat") String lat, @PathVariable("lon") String lon) {
        try{
            String request = String.format("%s?lat=%s&lon=%s&units=metric&appid=%s",
                    weatherUrl, lat, lon, appId);
            return restTemplate.getForEntity(request, Root.class);
        }catch (RestClientException e){
            return new ResponseEntity<>(HttpStatus.BAD_REQUEST);
        }
    }

截断查询示例:

        "lat": 1.4,
        "lon": 2.33
    },
    "weather": [
