RestTemplate请求失败时如何打印明细状态？

import org.springframework.http.client.DefaultResponseErrorHandler;
import org.springframework.web.client.ResponseErrorHandler;
import org.springframework.http.HttpStatus;
import org.springframework.http.client.ClientHttpResponse;
import java.io.IOException;

public class ErrorHandler extends DefaultResponseErrorHandler {

    @Override
    public void handleError(ClientHttpResponse response) throws IOException {
        if (response.getStatusCode() != HttpStatus.OK) {
            // 获取错误信息
            String errorBody = new String(response.getBody().readAllBytes());
            System.out.println("请求失败，错误信息：" + errorBody);
        }
    }
}

RestTemplate restTemplate = new RestTemplate();
restTemplate.setErrorHandler(new ErrorHandler());

String url = "http://example.com/api/endpoint";
try {
    ResponseEntity<String> response = restTemplate.getForEntity(url, String.class);
    // 处理成功响应
} catch (Exception e) {
    // 请求失败，错误信息已经在ErrorHandler中打印出来了
}
