RestTemplate.postForObject and Lists

Question

嗨，我希望客户端使用restfull Web服务。我使用springboot，服务返回一个只有一个OBJECT的JSON列表。我想像这个一样使用RestTemplate的postForObject Api

ResponseEntity<List<RetrieveRichiestaResponseDto>> result = restTemplate.postForObject(
uri,
entity,
new ParameterizedTypeReference<List<RetrieveRichiestaResponseDto>>() {});

为什么它会给我这个错误

> The method postForObject(String, Object, Class<T>, Object...) in the
> type RestTemplate is not applicable for the arguments (String,
> HttpEntity<capture#3-of ?>, new  
> ParameterizedTypeReference<List<RetrieveRichiestaResponseDto>>(){})

谢谢帮助！

Answer 1

restTemplate.postForObject()不支持ParameterizedTypeReference<>

使用restTemplate.exchange()

ResponseEntity<List<RetrieveRichiestaResponseDto>> result = restTemplate.exchange(uri, HttpMethod.POST, entity, 
new ParameterizedTypeReference<List<RetrieveRichiestaResponseDto>>() {});
