Aliware MQ 使用代理

Aliware MQ 使用中遇到代理问题

在学习使用Aliware MQ过程中，遇到了如下错误。

Exception in thread “main”

异常原因是因为网络使用了代理，需要在代码中加入代理参数。

Java中设置代理可以使用Authenticator类，但Authenticator类是一个抽象类，所以需要实现一下：

public class BasicAuthenticator extends Authenticator {
StringuserName;
String password;
public BasicAuthenticator(String userName, String password) {
this.userName = userName;
this.password = password;
}
/**
* Called when password authorization is needed. Subclasses should override the default implementation, which
* returns null.
*
* @return The PasswordAuthentication collected from the user, or null if none is provided.
*/
@Override
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(userName, password.toCharArray());
}
}

在业务类中加入以下代码块：

static{
System.setProperty(“http.proxyHost”, “proxy.*.com”);
System.setProperty(“http.proxyPort”, “8080”);
Authenticator.setDefault(new BasicAuthenticator(“XXX”, “XXXX”));
}
