抛出RestClientException时如何检索HTTP状态代码和响应正文？

问题描述

RestTemplate 的方法，例如 postForEntity（） throw RestClientException 。我想从catch块中的异常对象中提取HTTP状态代码和响应主体。我该怎么做？

The methods of RestTemplate such as postForEntity() throw RestClientException. I would like to extract the HTTP status code and response body from that exception object in the catch block. How can I do that?

推荐答案

而不是捕捉 RestClientException ，赶上特殊的 HttpClientErrorException 。

Instead of catching RestClientException, catch the special HttpClientErrorException.

以下是一个例子：

try {
    Link dataCenterLink = serviceInstance.getLink("dataCenter");
    String dataCenterUrl = dataCenterLink.getHref();
    DataCenterResource dataCenter =
        restTemplate.getForObject(dataCenterUrl, DataCenterResource.class);
    serviceInstance.setDataCenter(dataCenter);
} catch (HttpClientErrorException e) {
    HttpStatus status = e.getStatusCode();
    if (status != HttpStatus.NOT_FOUND) { throw e; }
}

提供和分别获取状态代码和正文。

HttpClientErrorException provides getStatusCode and getResponseBodyAsByteArray to get the status code and body, respectively.
