ClassCastException：RestTemplate 返回 ListLinkedHashMap 而不是 ListMymodelClass

Java
// 创建一个RestTemplate对象
RestTemplate restTemplate = new RestTemplate();
// 创建一个HttpHeaders对象，用于设置请求头
HttpHeaders headers = new HttpHeaders();
headers.setcontentType(MediaType.APPLICATION_JSON);
// 创建一个HttpEntity对象，用于发送请求
HttpEntity<String> entity = new HttpEntity<>(headers);
// 发送GET请求，获取返回的JSON数据
ResponseEntity<List<LinkedHashMap>> responseEntity = restTemplate.exchange(
    "http://api.example.com/data",
    HttpMethod.GET,
    entity,
    new ParameterizedTypeReference<List<LinkedHashMap>>() {}
);
// 将返回的JSON数据转换为List<MymodelClass>对象
List<LinkedHashMap> responseData = responseEntity.getBody();
List<MymodelClass> mymodelList = new ArrayList<>();
for (LinkedHashMap map : responseData) {
    MymodelClass mymodel = new MymodelClass();
    mymodel.setId((Integer) map.get("id"));
    mymodel.setName((String) map.get("name"));
    // ... 其他字段的转换
    mymodelList.add(mymodel);
}
