Could not extract response: no suitable HttpMessageConverter found for response type [class com.exam

报错信息：Could not extract response: no suitable HttpMessageConverter found for response type [class com.example.vo.WeatherData] and content type [application/octet-stream]

这是在用restTemplate获取uri返回数据，进行数据转换的时候报错的，原来的代码如下：

@Service
public class WeatherServiceImpl implements WeatherService{

@Autowired
   RestTemplate restTemplate;

   String uri = "http://wthrcdn.etouch.cn/weather_mini?city=深圳";

@Override
   public WeatherData getWeather() {
       ResponseEntity<WeatherData> weatherData = restTemplate.getForEntity(uri, WeatherData.class);
       return weatherData.getBody();
   }
}

这里无法直接转换为对象，需要先转为String，再转为自己所需对象，修改后的代码如下

@Service
public class WeatherServiceImpl implements WeatherService{

@Autowired
   RestTemplate restTemplate;

   String uri = "http://wthrcdn.etouch.cn/weather_mini?city=深圳";

@Override
   public WeatherData getWeather() {
       ResponseEntity<String> weatherData = restTemplate.getForEntity(uri, String.class);
       //使用ObjectMapper进行处理
       ObjectMapper mapper = new ObjectMapper();
       if(weatherData.getStatusCodeValue() == 200){
           String response = weatherData.getBody();
           WeatherData weatherData2 = null;
           try {
               weatherData2 = mapper.readValue(response, WeatherData.class);
           } catch (Exception e) {
               e.printStackTrace();
           }
           return weatherData2;
       }
       return null;
   }
}

修改这样，运行后，请求成功
