Spring Rest Client want to see error message instead of exception
提问by Amar
I have a spring rest client. when authentication details are not provided in the headers and I hit the service with
我有一个春季休息客户。当标头中未提供身份验证详细信息时，我点击了该服务
ResponseEntity<String> resp = restTemplate.exchange(url, HttpMethod.GET, request, String.class);
I get exception :
我得到例外：
invoking error handler Exception in thread "main" org.springframework.web.client.HttpClientErrorException: 401 Unauthorized at org.springframework.web.client.DefaultResponseErrorHandler.handleError(DefaultResponseErrorHandler.java:91)
在线程“main”org.springframework.web.client.HttpClientErrorException 中调用错误处理程序异常：401 未经授权在 org.springframework.web.client.DefaultResponseErrorHandler.handleError(DefaultResponseErrorHandler.java:91)
But when I hit the url on mozilla browser, I get message like
但是当我在 mozilla 浏览器上点击 url 时，我收到类似的消息
{"errors":[{"code":"xxxx","reason":"xxxx"}]}
Now here is what i want: i want to capture this error message in my code instead of getting 401 exception. I tried to see if there is anything in the response. But the response received is null. How can I capture the error message received from the webservice ?
现在这就是我想要的：我想在我的代码中捕获此错误消息，而不是获取 401 异常。我试图查看响应中是否有任何内容。但是收到的响应是空的。如何捕获从网络服务收到的错误消息？

I feel odd to post answer for my own question. But i finally achieved it through the following...
我觉得很奇怪为我自己的问题发布答案。但我最终通过以下方式实现了它......
} catch (HttpClientErrorException e) {
System.out.println(e.getStatusCode());
System.out.println(e.getResponseBodyAsString());
}
I was incorrectly searching for errors in response entity. But it is available in the exception.
我错误地搜索响应实体中的错误。但它在异常中可用。
