这里描述了什么样的基于 Java 的 Web 应用程序?我有一个基于 Spring MVC 的 Web 应用程序,遇到了与此处提到的相同的问题。
我尝试了两种在我的应用中配置 SOCKS 代理的方法:
- 使用命令行 JVM 参数。
- 使用这里提到的 java 代码,包装在一个 Bean 中,我将它加载到我的根应用程序上下文中。
我的 Java 类作为 bean 加载:
package be.example.backend.configuration;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import java.net.Authenticator;
import java.net.MalformedURLException;
import java.net.PasswordAuthentication;
import java.net.URL;
public class ProximoSocksConfig {
private static final Logger LOGGER = LoggerFactory.getLogger(ProximoSocksConfig.class);
private static final String PROXIMO_ENV_VAR = "PROXIMO_URL";
private static final String PROXIMO_PORT = "1080";
public ProximoSocksConfig() throws MalformedURLException {
setup();
}
/**
* Setup Proximo proxying
*
* @return True if Proximo was configured, false if the Proximo environment variable was not found
*/
public static boolean setup() throws MalformedURLException {
String proximoUrl = System.getenv(PROXIMO_ENV_VAR);
if (proximoUrl != null) {
URL proximo = new URL(proximoUrl);
String userInfo = proximo.getUserInfo();
String user = userInfo.substring(0, userInfo.indexOf(':'));
String password = userInfo.substring(userInfo.indexOf(':') + 1);
String host = proximo.getHost();
System.setProperty("socksProxyHost", host);
System.setProperty("socksProxyPort", PROXIMO_PORT);
Authenticator.setDefault(new ProxyAuth(user, password));
LOGGER.info("{} specified; using <{}:{}> {}:{} as SOCKS proxy", PROXIMO_ENV_VAR, user, password, host,
PROXIMO_PORT);
return true;
}
LOGGER.info("{} environment variable not set", PROXIMO_ENV_VAR);
return false;
}
private static class ProxyAuth extends Authenticator {
private final PasswordAuthentication passwordAuthentication;
private ProxyAuth(String user, String password) {
passwordAuthentication = new PasswordAuthentication(user, password.toCharArray());
}
@Override
protected PasswordAuthentication getPasswordAuthentication() {
return passwordAuthentication;
}
}
}
我的基于 XML 的 根应用程序上下文:
<!-- Proximo SOCKS proxy configuration -->
<bean id="proximoSocksConfig" class="be.example.backend.configuration.ProximoSocksConfig"/>
我不再收到绑定错误,因为不再使用 proximo 二进制包装器,但我的应用程序无法通过 Proximo 提供的公共 IP 地址访问(我使用 Proximo Starters 包)。
