Java 连接本身具有构造函数的Bean

我有一个web服务客户端，它有一个验证器类。验证器需要用户名/密码。正在寻找有关如何使用Spring注入凭据的帮助

我应该将user/pass注入验证器还是注入正在实例化验证器的客户端

任何具体的例子都将不胜感激，因为我是春天的新手

这是两个组件的外观：

@Controller
    public class WSClient {
        @Autowired
        MyAuthenticator myAuthenticator;
    }
}

具有以下凭据的身份验证程序：

public class MyAuthenticator extends Authenticator {
    private final String userName;
    private final String passWord;

    public MyAuthenticator(String userName, String passWord) {
        this.userName = userName;
        this.passWord = passWord;
    }

    @Override
    protected PasswordAuthentication getPasswordAuthentication() {
        return new PasswordAuthentication(this.userName, this.passWord.toCharArray());
    }
}

---

使用

@Value

在

Authentication

bean中设置用户名/密码

@Component
public class MyAuthenticator extends Authenticator {
    @Value("${credentials.username}")
    private final String userName;
    @Value("${credentials.password}")
    private final String passWord;

    public MyAuthenticator(String userName, String passWord) {
        this.userName = userName;
        this.passWord = passWord;
    }

    @Override
    protected PasswordAuthentication getPasswordAuthentication() {
        return new PasswordAuthentication(this.userName, this.passWord.toCharArray());
    }
}

和在XML文件中

加

并将

凭证.properties

放在类路径中

使用

@Value

在

身份验证

bean中设置用户名/密码

@Component
public class MyAuthenticator extends Authenticator {
    @Value("${credentials.username}")
    private final String userName;
    @Value("${credentials.password}")
    private final String passWord;

    public MyAuthenticator(String userName, String passWord) {
        this.userName = userName;
        this.passWord = passWord;
    }

    @Override
    protected PasswordAuthentication getPasswordAuthentication() {
        return new PasswordAuthentication(this.userName, this.passWord.toCharArray());
    }
}

和在XML文件中

加

并将

credentials.properties

放入类路径中
