问答我看还是上stackoverflow吧:

https://stackoverflow.com/questions/11178937/spring-resttemplate-gives-500-error-but-same-url-credentails-works-in-restcli

老外说要这样子初始化：

ClientHttpRequestFactory requestFactory = new     
      HttpComponentsClientHttpRequestFactory(HttpClients.createDefault());

RestTemplate restTemplate = new RestTemplate(requestFactory);
