当我提供Class targetClass作为
新的HashMap >>（）。getClass（）
Response2被解析，我在Map中得到结果，但是response1（Single Document）不起作用，并返回null。
或者如果我将Class targetClass作为新的HashMap >（）。getClass（）提供，则Response1会被解析，并且我会在Map中得到结果，但是response2（Multiple Documents）不会无法正常工作并返回null。
我不确定如何处理和解析服务的两个响应？
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。

我会这样解决
Gson gson = new GsonBuilder().create();
responseObject = gson.fromJson(jsonString, MyClass.class);
我的课
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）
Maven对Gson的依赖
<dependency>
<groupId>com.google.code.gson</groupId>
<artifactId>gson</artifactId>
<version>2.4</version>
