Question

我看到很多问题，但没有解决我的问题。我使用elasticsearch搜索查询json使用spring resttemplate搜索我的数据。请帮忙。

我在asyntask 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

您的查询searchJson无效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}}}]}}}";

Answer 2

我遇到了同样的问题。异常消息不是很有帮助。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。你会看到如下错误：

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

HttpClientErrorException：使用spring restemplate在弹性搜索中搜索时出现400 Bad Request
