带有用于 NTLM 身份验证的 http 客户端的 Spring Rest 模板

问题描述

我们在 IIS 服务器中部署了一个基于 NTLM 身份验证的 Web 服务.

We have a web service deployed in IIS server which authenticate based on NTLM authentication.

当我尝试通过在 httpCleint UserNamePasswordCredentials 中传递用户名和密码来访问 Web 服务时，收到警告为

When i try to access the web service by passing username and password in httpCleint UserNamePasswordCredentials, am getting warnings as

NTLM authentication error: Credentials cannot be used for NTLM authentication: org.apache.http.auth.UsernamePasswordCredentials

请说明如何使用spring rest模板使用http客户端通过用户名和密码通过NTLM认证.

Please clarify how to user http client with spring rest template to pass the NTLM authentication with user name and password.

注意:虽然收到警告消息，但也收到回复.

Note:Though am getting the warning message, am also getting response.

推荐答案

只需定义以下类即可.

public class NtlmAuthenticator extends Authenticator {

        private final String username;
        private final char[] password;

        public NtlmAuthenticator(final String username, final String password) {
            super();
            this.username = username;
            this.password = password.toCharArray();
        }

        @Override
        public PasswordAuthentication getPasswordAuthentication() {
            return (new PasswordAuthentication(username, password));
        }
    }

然后添加以下代码.大功告成.它开始工作了.

then add the following code.Thats it.It started working.

NtlmAuthenticator authenticator = new NtlmAuthenticator(userName,
                    password);
            Authenticator.setDefault(authenticator);
