Question

我已将我的EJB应用程序从5.0.1 JBOSS迁移到JBOSS EAP 7。我想在我的EJB拦截器（或bean）中检测客户端的IP地址

String currentThreadName = Thread.currentThread().getName();
result: default task-16

代码不再有效。如何获取客户端的IP地址？

Answer 1

您可以尝试远程连接和IP地址。我不确定它有多可靠，因为org.jboss.as.security-api是一个已弃用的模块，可能会在将来的版本中删除。

之后尝试下面的内容：

容器拦截器：

import javax.interceptor.AroundInvoke;
import javax.interceptor.InvocationContext;
import java.net.InetAddress;
import java.security.Principal;

import org.jboss.remoting3.Connection;
import org.jboss.remoting3.security.InetAddressPrincipal;
import org.jboss.as.security.remoting.RemotingContext;


public class ClientIpInterceptor {

    @AroundInvoke
    private Object iAmAround(final InvocationContext invocationContext) throws Exception {
        InetAddress remoteAddr = null;
        Connection connection = RemotingContext.getConnection();

        for (Principal p : connection.getPrincipals()) {
            if (p instanceof InetAddressPrincipal) {
                remoteAddr = ((InetAddressPrincipal) p).getInetAddress();
                break;
            }
        }

        System.out.println("IP " + remoteAddr);

        return invocationContext.proceed();
    }
}

的JBoss-ejb3.xml：

<?xml version="1.0" encoding="UTF-8"?>
<jboss xmlns="http://www.jboss.com/xml/ns/javaee"
       xmlns:jee="http://java.sun.com/xml/ns/javaee"
       xmlns:ci ="urn:container-interceptors:1.0">

    <jee:assembly-descriptor>
        <ci:container-interceptors>
            <jee:interceptor-binding>
                <ejb-name>*</ejb-name>
                <interceptor-class>ClientIpInterceptor</interceptor-class>
            </jee:interceptor-binding>
        </ci:container-interceptors>
    </jee:assembly-descriptor>
</jboss>

的JBoss部署-structure.xml：

<?xml version="1.0" encoding="UTF-8"?>
<jboss-deployment-structure xmlns="urn:jboss:deployment-structure:1.2">
<deployment>
    <dependencies>
        <module name="org.jboss.remoting3" />
        <module name="org.jboss.as.security-api" />
    </dependencies>
</deployment>
</jboss-deployment-structure>

关于JBoss社区维基的这篇文章[1]正好解决了你的问题。在JBoss 5之前，显然必须从工作线程名称解析IP地址。这似乎是在早期版本中实现它的唯一方法。

private String getCurrentClientIpAddress() {
    String currentThreadName = Thread.currentThread().getName();
    System.out.println("Threadname: "+currentThreadName);
    int begin = currentThreadName.indexOf('[') +1;
    int end = currentThreadName.indexOf(']')-1;
    String remoteClient = currentThreadName.substring(begin, end);
    return remoteClient;
}
