WSWebservice模板UnsupportedCallbackException错误

该错误是由于WS Webservice模板未能处理传递给客户端回调处理程序的验证请求而导致的。为了解决这个问题，您需要为客户端回调处理程序添加一个验证回调处理程序。以下是一个示例代码，它添加了一个UsernamePasswordCallback用于处理客户端验证请求：

public class ClientPasswordCallback implements CallbackHandler {
 
    public void handle(Callback[] callbacks) throws IOException, UnsupportedCallbackException {
 
        for (int i = 0; i < callbacks.length; i++) {
 
            if (callbacks[i] instanceof UsernameCallback) {
                UsernameCallback uc = (UsernameCallback) callbacks[i];
                uc.setUsername("clientUser");
            } else if (callbacks[i] instanceof PasswordCallback) {
                PasswordCallback pc = (PasswordCallback) callbacks[i];
                pc.setPassword("clientPassword".toCharArray());
            } else {
                throw new UnsupportedCallbackException(callbacks[i], "Unrecognized Callback");
            }
        }
    }
}

然后，您需要在客户端代码中为回调处理程序设置一个回调处理程序链，如下所示：

MyService myService = new MyService();
MyServicePortType port = myService.getMyServicePort();

BindingProvider bp = (BindingProvider) port;
Map<String, Object> reqContext = bp.getRequestContext();
reqContext.put(BindingProvider.USERNAME_PROPERTY, "clientUser");
reqContext.put(BindingProvider.PASSWORD_PROPERTY, "clientPassword");

ClientPasswordCallback callbackHandler = new ClientPasswordCallback();
reqContext.put(WSSecurityCallbackHandler.CALLBACK_HANDLER, callbackHandler);

以上代码设置了用户名和密码，并将回调处理程序链设置为ClientPasswordCallback类的实例。这应该可以解决UnsupportedCallbackException错误。
