Question

我想得到：List<User>。我有端点（GET）来获取用户。得到：

[
  {
    "id": "d71dcbca-54f3-4b19-aec4-3776bfe34730",
    "name": "test",
    "surname": "test",
    "login": "test",
    "password": "-26104458",
    "email": "test",
    "role": "user"
  }
]

我尝试使用rest模板获取此列表：

ResponseEntity<User[]> responseEntity = rest.getForEntity(my-endpoint, User[].class);
        return Arrays.asList(responseEntity.getBody());

但我得到这个错误：

org.springframework.web.client.RestClientException: Could not extract response: no suitable HttpMessageConverter found for response type

问题：如何使用其他模板获取List<User>？

Answer 1

也许你想尝试这种方法：

ResponseEntity<List<User>> responseEntity = rest.exchange(
                "your-endpoint",
                HttpMethod.GET,
                null,
                new ParameterizedTypeReference<List<User>>() {
                });
