要了解Apache Artemis的最大磁盘使用量和地址满策略，可以使用以下方法：

1. 配置最大磁盘使用量：在Artemis的broker配置文件（如broker.xml）中，可以设置元素来指定最大磁盘使用量的百分比。例如，将最大磁盘使用量设置为80%：

80

2. 配置地址满策略：在Artemis的broker配置文件中，可以为每个地址（queue或topic）设置地址满策略。一种常见的地址满策略是将消息发送到死信队列（DLQ），以便后续处理。在元素中，可以为每个地址设置元素，并指定死信队列的名称。例如：

   
      PAGE
      DLQ
   

3. 使用Java代码示例：

import org.apache.activemq.artemis.api.core.TransportConfiguration;
import org.apache.activemq.artemis.api.core.client.*;
import org.apache.activemq.artemis.api.core.management.ManagementHelper;
import org.apache.activemq.artemis.api.core.management.ResourceNames;
import org.apache.activemq.artemis.core.config.Configuration;
import org.apache.activemq.artemis.core.remoting.impl.netty.NettyConnectorFactory;

import javax.management.MBeanServerConnection;
import javax.management.ObjectName;
import java.util.HashMap;
import java.util.Map;

public class ArtemisDiskUsageExample {

    public static void main(String[] args) throws Exception {
        // Create the configuration
        Configuration configuration = new Configuration();
        configuration.setPersistenceEnabled(true);

        // Create the transport configuration
        Map transportParams = new HashMap<>();
        transportParams.put("host", "localhost");
        transportParams.put("port", "61616");
        TransportConfiguration transportConfiguration =
                new TransportConfiguration(NettyConnectorFactory.class.getName(), transportParams);

        // Create the core client
        ServerLocator serverLocator = ActiveMQClient.createServerLocatorWithoutHA(transportConfiguration);
        ClientSessionFactory sessionFactory = serverLocator.createSessionFactory();
        ClientSession session = sessionFactory.createSession();

        // Get the broker's maximum disk usage
        MBeanServerConnection mbsc = session.management().getMBeanServerConnection();
        ObjectName brokerName = ObjectName.getInstance(ResourceNames.BROKER);
        String maxDiskUsage = (String) mbsc.getAttribute(brokerName, "MaxDiskUsage");

        // Get the address full policy for a specific address
        ObjectName addressControlName = ObjectName.getInstance(ResourceNames.CORE_ADDRESS + "myQueue");
        String addressFullPolicy = (String) mbsc.getAttribute(addressControlName, "AddressFullMessagePolicy");

        System.out.println("Max Disk Usage: " + maxDiskUsage);
        System.out.println("Address Full Policy: " + addressFullPolicy);

        session.close();
        serverLocator.close();
    }
}

以上示例代码通过Java代码连接到Artemis broker，并使用JMX获取最大磁盘使用量和地址满策略的配置信息。
