Question

在spring boot（1.4.1）应用程序中，我尝试使用其余模板

 @GetMapping(value = "/visits")
    public ResponseEntity<CustomPageImpl<VisitDto>> getVisits(Pageable pageRequest) {
          return restTemplate.getForEntity("", new TypeReference<CustomPageImpl<VisitDto>>() {});
    }

像在这个thread中的Ali Dehghani的回答一样，我创建了一个CustomPageImpl

关于TypeReference，导入com.fasterxml.jackson.core.type.TypeReference;

我收到此消息

no suitable method found for getForEntity(String,<anonymous TypeReference<CustomPageImpl<VisitDto>>>)
    method RestTemplate.<T#1>getForEntity(String,Class<T#1>,Object...) is not applicable
      (cannot infer type-variable(s) T#1
        (argument mismatch; <anonymous TypeReference<CustomPageImpl<VisitDto>>> cannot be converted to Class<T#1>))
    method RestTemplate.<T#2>getForEntity(String,Class<T#2>,Map<String,?>) is not applicable
      (cannot infer type-variable(s) T#2
        (actual and formal argument lists differ in length))
    method RestTemplate.<T#3>getForEntity(URI,Class<T#3>) is not applicable
      (cannot infer type-variable(s) T#3
        (argument mismatch; String cannot be converted to URI))
  where T#1,T#2,T#3 are type-variables:
    T#1 extends Object declared in method <T#1>getForEntity(String,Class<T#1>,Object...)
    T#2 extends Object declared in method <T#2>getForEntity(String,Class<T#2>,Map<String,?>)
    T#3 extends Object declared in method <T#3>getForEntity(URI,Class<T#3>)

用

ResponseEntity<CustomPageImpl<VisitDto>> response = restTemplate.getForEntity(URI.create("url"), new TypeReference<ResponseEntity<CustomPageImpl<VisitDto>>>() {});

得到同样的错误

尝试getForEntity(URI url,Class responseType)

    @GetMapping(value = "/visits")
        public ResponseEntity<CustomPageImpl<VisitDto>> getVisits(Pageable pageRequest) {
              ResponseEntity<CustomPageImpl<VisitDto>> response = restTemplate.getForEntity(Uri.parse("url"), new TypeReference<CustomPageImpl<VisitDto>>() {});
return response;
        }

使用restTemplate使用服务
