ActiveMq消息对象进行序列化时报错

先贴出生产者的主代码:

JianRen jianRen = new JianRen("名字","描述");
        ActiveMQObjectMessage mes=(ActiveMQObjectMessage)session.createObjectMessage(jianRen);
        mes.setObject(jianRen);
        producer.send(mes);

其中JianRen就是一个对象：

public class JianRen implements Serializable{
	String name;
	String info;
	public JianRen(String name,String info) {
		this.info=info;
		this.name=name;
	}
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	public String getInfo() {
		return info;
	}
	public void setInfo(String info) {
		this.info = info;
	}
}

然后是订阅者的核心代码：

                    ActiveMQObjectMessage objectmes=(ActiveMQObjectMessage)message;
                    JianRen jianren = (JianRen) objectmes.getObject();
                    System.out.println(jianren.getName());

然后报错了：

This class is not trusted to be serialized as ObjectMessage payload. Please take a look at http://activemq.apache.org/objectmessage.html for more information on how to configure trusted classes.

出现这个问题的原因在于：从ActiveMQ5.12.2 开始，为了增强这个框架的安全性，ActiveMQ将强制用户配置可序列化的包名。网上找到的答案是针对Spring配置文件的：

但是我并没有用配置文件，不过根据官方文档也可以看出怎么修改自己的代码：

官方文档：http://activemq.apache.org/objectmessage.html

即：

ActiveMQConnectionFactory connectionFactory = new ActiveMQConnectionFactory(user,password,url);
        connectionFactory.setTrustAllPackages(true);//这就是和配置文件起到一样作用

其中多种更改方法可查看官方文档。
