无法使用Java代码访问Web服务，但是通常可以从Chrome看到其wsdl

Question

大家！

我遇到了一个非常奇怪的问题。 我在Netbeans中编写了一个Web服务示例。 在Netbeans IDE中，Web服务客户端和Web服务运行得很流畅，即使运行缓慢。 但是，在将其部署到Tomcat 7.0后，客户端无法正常评估Web服务。

wsdl的网址是http://221.207.220.12:7001/InterWebService/InterService.wsdl?wsdl ，可通过Chrome浏览器查看。

以下是异常信息：

Answer 1

我也遇到过类似的问题，并找到了根本原因，如下所示：

在调查问题的根本原因时，发现WSDL文件中“ wsdl：port”元素的“ soap：address”所引用的URL与通过其调用Web服务的URL不匹配。 根据SOAP规范，这是不正确的。

在我们的环境中，“ soap：address”是指wsdl文件中的“反向代理” URL（即“ xxx.com:9040/service.asmx”），这不是我们试图通过其访问Ace服务的实际URL（即“ xxx.com/service.asmx“）

Answer 2

听起来您需要将代理配置为Java客户端代码。 你可以用类似的方法

String proxyHost = "192.168.2.2";
String proxyPort = "3128";
System.out.println("Setting up with proxy: " + proxyHost + ":" + proxyPort);
System.setProperty("http.proxyHost", proxyHost);
System.setProperty("http.proxyPort", proxyPort);
System.setProperty("http.nonProxyHosts", "localhost|127.0.0.1");

假设您的代理位于“ 192.168.2.2:3128”。 我相信您在启动时需要执行一次此操作，然后再访问任何HTTP连接。
