我试图创建SOAP客户端来与服务器通信。C# 一切都运行顺利,但在 Java 上我仍然会遇到一些异常。
我们公司是代理的幕后推手。SOAP 服务位于基本身份验证的后面。
小故事:我使用 Java 生成代码,从 wsdl 生成带有JAX_WS模式
/**
* This class was generated by the JAX-WS RI.
* JAX-WS RI 2.2.9-b130926.1035
* Generated source version: 2.2
*/
@WebServiceClient(name = "ServiceWs", targetNamespace = "http://www.web.org/Schema/Klient/Service", wsdlLocation = "https://app.web.org/KlientWS/ServiceWs.wsdl")
public class ServiceWs
extends Service {
public ServiceWs(URL wsdlLocation, QName serviceName, WebServiceFeature... features) {
super(wsdlLocation, serviceName, features);
}
...
}
并且使用某种实现身份验证和 cookie:
CookieHandler.setDefault(new CookieManager(null, CookiePolicy.ACCEPT_ALL));
Authenticator.setDefault(new Authenticator() {
@Override
protected PasswordAuthentication getPasswordAuthentication() {
System.setProperty("java.net.useSystemProxies", "true");
System.setProperty("proxySet", "true");
System.setProperty("proxyHost", localProxyHost);
System.setProperty("proxyPort", localProxyPort);
System.setProperty("proxyUser", localProxyUser);
System.setProperty("proxyPassword", localProxyPassword);
String prot = getRequestingProtocol().toLowerCase();
// Requesting protocol
System.setProperty(prot + ".proxyHost", localProxyHost);
System.setProperty(prot + ".proxyPort", localProxyPort);
System.setProperty(prot + ".proxyUser", localProxyUser);
System.setProperty(prot + ".proxyPassword", localProxyPassword);
// if (getRequestorType() == RequestorType.PROXY) {
// if (getRequestingHost().toLowerCase().equals(localProxyHost.toLowerCase())) {
// if (Integer.parseInt(localProxyPort) == getRequestingPort()) {
// // Seems to be OK.
// return new PasswordAuthentication(localProxyUser, localProxyPassword.toCharArray());
// }
// }
// } else
if (getRequestorType() == RequestorType.SERVER) {
return new PasswordAuthentication(username, password.toCharArray());
}
return null;
}
});
和客户端的实施
ServiceWs client;
try {
URL url = new URL(endpointAddress);
client = new ServiceWs(url);
} catch (IOException e) {
client = new ServiceWs();
}
它只是在连接到 wsdl 文件时因 ProtocolException 而失败,重定向太多。

我知道身份验证详细信息正确且 Web 地址正确,因为我可以手动连接到 wsdl 文件。
问题是,正如代理设置中@beat建议的那样。我没有正确设置 NTLM,因为我们的代理用户位于不同的域中。
要设置的代码System.setProperty("http.auth.ntlm.domain", domain);
,设置后,一切都开始按预期工作。
在 J2SE 代理认证中可以看到更多内容。
private void createAuthentication(String localProxyHost, String localProxyPort,
String localProxyUser, String localProxyPassword, String domain,
String username, String password) {
if (!prepared) {
System.setProperty("java.net.useSystemProxies", "true");
System.setProperty("http.auth.ntlm.domain", domain);
System.setProperty("proxyHost", localProxyHost);
System.setProperty("proxyPort", localProxyPort);
System.setProperty("proxyUser", localProxyUser);
System.setProperty("proxyPassword", localProxyPassword);
prepared = true;
CookieHandler.setDefault(new CookieManager(null, CookiePolicy.ACCEPT_ALL));
Authenticator.setDefault(new Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(username, password.toCharArray());
}
});
}
}
根据Polostor的要求,我尝试写一个答案。NTLMv2 代理正在对用户进行身份验证,如果不成功,则重定向您。
由于我在不同站点使用不同的代理时遇到了很多问题,因此我建议使用代理田鼠。这将根据平台设置自动设置您的代理。
