具有通用responseType的通用restTemplateExchange

发布于 2025-01-14 02:36:06 字数 694 浏览 1 评论 0原文

我想创建一个自己的通用方法来调用restTemplate.exchange。特别是，我希望这个通用方法的签名是：

protected <T> ResponseEntity<T> genericExchange(String uri, HttpMethod method, @Nullable HttpEntity<?> requestEntity, -->responseType<--)

我将根据“responseType”区分 exchange 方法调用

如果 responseType 是 Class，我调用*交换(URI url, HttpMethod method, HttpEntity requestEntity, ClassresponseType)*
。 T>如果responseType是ParameterizedTypeReference， T> 我调用*交换(URI url, HttpMethod method, HttpEntity requestEntity, ParameterizedTypeReference< T> responseType)*

原文

I would like to create a own generic method that calls the restTemplate.exchange.
In particular I would like that the signature of this generic method to be :

protected <T> ResponseEntity<T> genericExchange(String uri, HttpMethod method, @Nullable HttpEntity<?> requestEntity, -->responseType<--)

I would differentiate what exchange method call according to "responseType"

if responseType is Class< T> I call * exchange(URI url, HttpMethod method, HttpEntity<?> requestEntity, Class< T> responseType)*
if responseType is ParameterizedTypeReference< T> I call * exchange(URI url, HttpMethod method, HttpEntity<?> requestEntity, ParameterizedTypeReference< T> responseType)*

我找到了这个答案，它对我有用：

无法获取通用 ResponseEntity;其中 T 是泛型类“SomeClass”

RestTemplate restTemplate = new RestTemplate();
restTemplate.exchange(pUrl, HttpMethod.POST, pEntity, new ParameterizedTypeReference<ResultListPage<MyObject>>() {});

I found this answer, and it was working for me:

Unable to get a generic ResponseEntity<T> where T is a generic class "SomeClass<SomeGenericType>"

RestTemplate restTemplate = new RestTemplate();
restTemplate.exchange(pUrl, HttpMethod.POST, pEntity, new ParameterizedTypeReference<ResultListPage<MyObject>>() {});
