参考下面的代码,我试图将结果转换为 Profile 类型模型并对其进行迭代以获取该字段。但是我得到了类转换异常。请参阅下面所附的示例响应,需要从结果中获取 pid。
//code
// search profile by profileId
SearchCriteria sc = new SearchCriteria(Profile.PROFILE_ID, EQUALS, profileId);
SearchInput searchInput = SearchInput.builder().criteria(sc).build();
HttpEntity<SearchInput> searchRequest = new HttpEntity<>(searchInput);
PageableResponse response = restTemplate.postForObject(searchUrl, searchRequest, PageableResponse.class);
Object results = response.getResults();
ArrayList<Profile> profiles = (ArrayList<Profile>) results;
System.out.println(profiles.get(0));
for(Profile p: profiles) {
log.trace(p.getId());
}
}
错误日志:
java.lang.ClassCastException: class java.util.LinkedHashMap cannot be cast to class com.model.profile.Profile (java.util.LinkedHashMap is in module java.base of loader 'bootstrap'; com.palmtree.matrimony.model.profile.Profile is in unnamed module of loader 'app')

我将此作为答案重新发布,因为它可能有助于 OP 解决问题。
您可以尝试使用 restTemplate.exchange()
方法并将 PageableResponse<Profile>
作为类型传递给 ParameterizedTypeReference
。我认为您不应该使用 PageableResponse 作为返回类型,因为您没有在此测试中测试分页。
