当我提供 Class < E > 目标Class 作为
new HashMap< String, List< Map < String , String>>>().getClass()
Response2 得到解析，我在 Map 中得到结果，但是 response1(Single Document) 不起作用并且 returns 为空。
或者如果我提供 Class < E > 目标 Class 作为 new HashMap< String , Map < String, String >>().getClass() Response1 得到解析，我在 Map 中得到结果，但是 response2(Multiple Documents) 不起作用并且 returns 为 null .
我不确定如何处理和解析来自服务的两个响应？
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();
