本文介绍了JspSourceDependent接口，它是Apache Jasper包中的一个抽象接口，用于标识依赖源代码的JSP类。内容展示了login_jsp类如何实现此接口，并提供了页面初始化、销毁方法以及获取依赖项的示例。
JspSourceDependent(Jsp基本类)属于jasper包
packageorg.apache.jasper.runtime;
importjava.util.Map;
public abstractinterface JspSourceDependent
{
public abstractMap<String, Long> getDependants();//基本抽象键值对
}
