spring-boot - Resttemplate 和补丁，无效

Question

我使用 Spring 1.4.3

我尝试调用网络服务

  @PatchMapping(value = "/members/{memberId}/card")
  public ResponseEntity updateMemberCardId(@PathVariable("memberId") Long memberId, @RequestBody String cardId) throws ResourceNotFoundException {
        memberService.updateMemberCardId(cardId, memberId);
        return new ResponseEntity<>(HttpStatus.NO_CONTENT);
  }

在我的申请中，

@Component
@Configuration
public class ClientRestConfig {

    @Bean
    public RestTemplate restTemplate(RestTemplateBuilder builder, @Value("${main.server.url}") String mainServerUrl, @Value("${commerce.username}") String commerceUsername, @Value("${commerce.password}") String commercePassword,  @Value("${connection.timeout}") int timeout) {
        return builder.setConnectTimeout(timeout).setReadTimeout(timeout).basicAuthorization(commerceUsername, commercePassword).rootUri(mainServerUrl).build();
    }

}

在另一种方法中我做

String cardId = "123456789";

HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_JSON);
HttpEntity<String> entity = new HttpEntity<>(cardId, headers);

ResponseEntity responseEntity =  restTemplate.patchForObject("/rest/members/1/card", entity, ResponseEntity.class);

我收到这个错误

java.net.ProtocolException: Invalid HTTP method: PATCH at java.net.HttpURLConnection.setRequestMethod(HttpURLConnection.java:440) ~[na:1.8.0_111] at sun.net.www.protocol.http.HttpURLConnection.setRequestMethod(HttpURLConnection.java:552) ~[na:1.8.0_111]

基于 ritesh.garg 的回答:

添加以下内容 dependency到您的类路径:

<dependency>
    <groupId>org.apache.httpcomponents</groupId>
    <artifactId>httpclient</artifactId>
    <version>4.5.6</version>
</dependency>

然后，创建您的 RestTemplate像这样:

    RestTemplate template = new RestTemplate(new HttpComponentsClientHttpRequestFactory());
