HttpClientErrorException:400使用spring重新模板在弹性搜索中搜索时请求错误

Question

我看到了很多关于这个问题的疑问，但没有解决我的问题。我使用elasticsearch json来使用SpringRESTTemplate搜索我的数据。请帮忙。

我在异步任务Android中这样做

@Override
protected List<JobPosts> doInBackground(Object[] objects) {
    List list = null;

    try {

        SearchForm searchForms = (SearchForm) objects[0];

        String searchJson="";




        String plainCreds = "*********:********";



        final String url = "********";
        RestTemplate restTemplate = new RestTemplate();
        restTemplate.getMessageConverters().add(new MappingJackson2HttpMessageConverter());

        HttpEntity<String> request = new HttpEntity<>(searchJson, headers);
        Log.d("location", "before exchange");
        ResponseEntity<JobPosts[]> response = restTemplate.exchange(url, HttpMethod.POST, request, JobPosts[].class);
        JobPosts[] jobPosts = response.getBody();

        Log.d("location", "after exchange");
        list = Arrays.asList(jobPosts);


    } catch (Exception e) {
        Log.d("location", e.getMessage());
    }

我得到了这个例外

Answer 1

我也有同样的问题。异常消息没有多大帮助。我必须做一个e.getResponseBodyAsString（），其中e是例外。我发现了详细的错误消息。您将看到如下错误：

{"errors":[{"code":"VALIDATION_FAILURE","source":{"pointer":"employee/attributes/child[0].role"},"detail":"... is invalid"}]}

您的查询search chJson是无效的JSON。我用{}包围了它：

String searchJson="{\"query\":{\"bool\":{\"must\":[{\"match\":{\"mandatorySkills.skillName\":\"j2ee\"}}],\"filter\":[{\"geo_distance\":{\"distance\":\"50km\",\"location\":{\"lat\":19.1237818,\"lon\":72.8907772}}},{\"range\":{\"minimumExperience\":{\"lte\":6}}},{\"range\":{\"maximumExperience\":{\"gte\":6}}}]}}}";
