java.net.ConnectException : Tried all: '1' addresses, 但无法通过 HTTP 连接到服务器

Question

我在Weblogic服务器中运行程序时遇到以下问题。

网址http://localhost:8080 在我这边是可以访问的，但是当我使用下面的代码连接服务器时，它失败并出现连接异常。

import com.sun.jersey.api.client.Client;
import com.sun.jersey.api.client.ClientResponse;
import com.sun.jersey.api.client.WebResource;
import com.sun.jersey.api.client.filter.HTTPBasicAuthFilter;

public static String invokeGet(String url, String dsl) {
  String url = "http://localhost:8080";
  Client clientInstance = Client.create();
  clientInstance.addFilter(new HTTPBasicAuthFilter("", ""));

  WebResource webResource = clientInstance.resource(url);

  ClientResponse response =
    webResource.entity(dsl).header("Content-type", "application/json").accept("application/json").get(ClientResponse.class);
     }

详细错误信息:

Caused by: java.net.ConnectException: Tried all: '1' addresses, but could not connect over HTTP to server: 'hostname', port: '8080'

还有一点是，我在集成服务器中可以正常运行它，但在独立服务器中无法运行它。

似乎是在服务器上检查配置属性defaultzone。也许您会在这里找到解决方案:

After days, looking thousand times on the same config file I realized the issue. At the end it was just a misspelling of defaultzone. After changing it to defaultZone everything works like expected. Thank you very much for your time.
