Java Spring RestTemplate身份验证性能问题

我使用SpringRESTTemplate从restful服务器检索对象，并使用拦截器进行基本身份验证。然而，我发现localhost和dev环境之间存在巨大的性能差异

在本地运行客户端和restful服务器时，RestTemplate getForObject需要3秒钟。在本地和DEV中的restful服务器上运行客户机时，需要59秒。我在DEV中的拦截器中做了一些日志记录，restful服务器响应非常快（在1秒内）。导致延迟的原因是getForObject，所以我猜在DEV RestTemplate中，将响应主体转换为对象需要很多时间

我在localhost和DEV中进行了相同的调用，因此我希望响应主体的大小相同。有人知道如何提高DEV的性能吗？非常感谢

拦截器：

public class BasicAuthInterceptor implements ClientHttpRequestInterceptor {

public static final Log log = LogFactory.getLog(BasicAuthInterceptor.class);

private String username;
private String password;

public BasicAuthInterceptor( String username, String password ) {
    this.username = username;
    this.password = password;
}

@Override
public ClientHttpResponse intercept(HttpRequest request, byte[] body, ClientHttpRequestExecution execution)
        throws IOException {
    //Build the auth-header
    final String auth = username + ":" + password;
    final byte[] encodedAuth = Base64.encodeBase64( auth.getBytes( Charset.forName( "US-ASCII" ) ) );
    final String authHeader = "Basic " + new String( encodedAuth );

    //Add the auth-header
    request.getHeaders().add( "Authorization", authHeader );

    log.info("Sending request to the data server");
    ClientHttpResponse response = execution.execute(request, body);
    log.info("Got response from the data server. Status: " + response.getStatusCode() + " " + response.getStatusText());
    log.info("Response header: " + response.getHeaders());

    return response;
} }

RestTemplate调用：

RestTemplate restTemplate = new RestTemplate();

            final List<ClientHttpRequestInterceptor> interceptors = new ArrayList<ClientHttpRequestInterceptor>();
            interceptors.add( new BasicAuthInterceptor( "user", "xxx" ) );
            restTemplate.setInterceptors( interceptors );

            AggregatedCptyExposure[] expoIq = restTemplate.getForObject(fullUrl, AggregatedCptyExposure[].class);

开发人员：

启用spring调试以获取有关提取器花费如此长时间的原因的日志详细信息。验证spring JAR及其依赖项在本地和开发人员之间的版本是否相同。此外，

RestTemplate

是线程安全的，并且拦截器对于所有请求都是相同的。考虑制作<代码> RestMadie，以及它的拦截器，为所有请求共享一个单独的作用域Spring bean。@安德鲁斯-谢谢您的响应！我试图通过向log4j.xml添加

来启用spring调试。但是，我没有获取提取器的日志详细信息。您能告诉我如何正确定义提取器的日志记录吗？它可能是一个依赖项jar，例如jackson。
