求助： JSF(primefaces)+hibernate+Spring java.io.NotSerializableException

[bjyuling]

在线等。欢迎来指点！
这是什么情况啊？为什么会在service中报序列化异常啊？
javaBean

package com.kccbest.hrams.cnodc.view;

		this.courseService = (CourseService) ServiceLocatorDefaultImpl.getInstance().getBean("courseService");
		lazyModel = getLazyDataModel();
//		getXmlData();
	}
}

异常

java.io.NotSerializableException

你把CourseServiceImpl中的bean实现implements Serializable

[bjyuling]

一个来看的人都没有么？还是我问问题的方式有问题，请高手指点。

[bjyuling]

额。有人来看了 感动。。所有的model类都实现了序列化接口。

[Seady]

get set方法有？

[qianzouxiong]

继续飘过

有啊。本来只需要那个bean和model类实现实例话接口就可以了，但不知道为什么现在出问题了。

[bjyuling]

<managed-bean-scope></managed-bean-scope>

那位大神可以介绍下jsf配置<managed-bean-scope></managed-bean-scope>这个里的有什么要特别注意的么？

[LFPoint]

谁可以告诉我org.primefaces.model.LazyDataModel这里面的LazyDataModel类的具体用法吗？
