RestTemplate处理请求状态码为非200的返回数据

@Configuration
public class RestTemplateConfig {

    @Bean
    public RestTemplate restTemplate(ClientHttpRequestFactory factory) {
        RestTemplate restTemplate = new RestTemplate(factory);
        ResponseErrorHandler responseErrorHandler = new ResponseErrorHandler() {
            @SuppressWarnings("NullableProblems")
            @Override
            public boolean hasError(ClientHttpResponse clientHttpResponse) {
                return true;
            }
            @SuppressWarnings("NullableProblems")
            @Override
            public void handleError(ClientHttpResponse clientHttpResponse) {
            }
        };
        restTemplate.setErrorHandler(responseErrorHandler);
        return restTemplate;
    }

    @Bean
    public ClientHttpRequestFactory simpleClientHttpRequestFactory() {
        SimpleClientHttpRequestFactory factory = new SimpleClientHttpRequestFactory();
        factory.setConnectTimeout(15000);
        factory.setReadTimeout(5000);
        return factory;
    }
}
