我有一个Rest模板交换获取服务。该服务返回响应如下：

当我提供 Class＆lt; E> targetClass as 新的HashMap＆lt;字符串，列表＆lt;地图＆lt;字符串，字符串＆gt;＆gt;＆gt;（）。getClass（） 解析Response2并在Map中得到结果，但是response1（单个文档）不起作用并返回为null。

或者如果我提供类＆lt; E> targetClass as new HashMap＆lt;字符串，地图＆lt; String，String＆gt;＆gt;（）。getClass（）对Response1进行解析，我在Map中得到结果，但是response2（多个文档）不起作用并返回为null。

我不确定如何处理和解析来自服务的响应？

responseMap =  restUtils.findDocuments(urlBuilder.build(),new HashMap<String,List<Map<String,String>>>().getClass());


**RestUtils Class:** 
public <E> E findDocuments(String url,Class<E> targetClass) throws JsonProcessingException {

    MultiValueMap<String, String> headers = new LinkedMultiValueMap<String, String>();
    headers.add(ACCEPT, MediaType.APPLICATION_JSON_VALUE);
    headers.add(CONTENT_TYPE,MediaType.APPLICATION_JSON_VALUE);
    //headers.add("id", StringUtils.trimToEmpty(policyNo));
    HttpEntity<Object> requestEntity = new HttpEntity<Object>(headers);
    ResponseEntity<E> response = restTemplate.exchange(url,HttpMethod.GET, requestEntity, targetClass);
    ObjectMapper mapper = new ObjectMapper();
    String jsonResponse = mapper.writeValueAsString(response); 
    System.out.println(jsonResponse);

    return (E) response.getBody();
}

任何帮助将不胜感激。

我以这种方式解决它

        Gson gson = new GsonBuilder().create();
        responseObject = gson.fromJson(jsonString, MyClass.class);

MyClass的

public class MyClass {
    List<ArrayEntry> irpage;

    public class ArrayEntry {
        String drawer;
        String folderNumber;
        ...
    }
}

使用您需要的修饰符（公共/私人）

Gson的Maven依赖

    <dependency>
        <groupId>com.google.code.gson</groupId>
        <artifactId>gson</artifactId>
        <version>2.4</version>
