Handle HttpClientErrorException $ BadRequest：黄瓜RestTemplate中的400错误请求

Question

[您好，我编写了一个Cucumber测试用例，其中我以XML主体发送POST请求，该请求的输出为XML主体出现400错误，这是预期的，当我抛出该请求时，我也得到了，但是我获取如下：

org.springframework.web.client.HttpClientErrorException$BadRequest: 400 Bad Request
    at org.springframework.web.client.HttpClientErrorException.create(HttpClientErrorException.java:79)
    at org.springframework.web.client.DefaultResponseErrorHandler.handleError(DefaultResponseErrorHandler.java:97)

    at ✽.Given User hits the getSlot request with OrderEnricher with "2020-40-32" and "150" and "MK92NW"(OrderEnricher_Negative.feature:5)

并且我的测试步骤因请求失败而失败，但是理想情况下这是我的预期，我想通过我的测试步骤和方案，不确定我应该如何处理，我尝试了多种方法。谁能帮忙吗？

 public static ResponseEntity<String> POSTrestTemplatewithXML(URI uri, String XMLforPOST){
        ResponseEntity<String> responseEntity = null;
        try {
            RestTemplate restTemplate=new RestTemplate();
            List<HttpMessageConverter<?>> messageConverters=new ArrayList<HttpMessageConverter<?>>();
            messageConverters.add(new StringHttpMessageConverter());
            restTemplate.setMessageConverters(messageConverters);
            HttpHeaders headers=new HttpHeaders();
            headers.setContentType(MediaType.APPLICATION_XML);
            HttpEntity<String> request=new HttpEntity<String>(XMLforPOST, headers);
            responseEntity=restTemplate.postForEntity(uri, request, String.class);



        }
        catch (Exception e){
            System.out.println("RESPONSE-"  +responseEntity);
            byte[] bytes = ((HttpClientErrorException.BadRequest)e).getResponseBodyAsByteArray();
            assertTrue(true);

//Convert byte[] to String
            String s = new String(bytes);

            System.out.println(s);
            e.printStackTrace();
        }
        return responseEntity;
    }

请更新您的catch方法，如下所示：

try{
  //your code
} catch (HttpClientErrorException e){
  //your code
}
