ContextLoaderListener是一个监听器,其实现了ServletContextListener接口,其用来监听Servlet,当tomcat启动时会初始化一个Servlet容器,这样 ContextLoaderListener会监听到Servlet的初始化,这样在Servlet初始化之后我们就可以在 ContextLoaderListener中也进行一些初始化操作。看下面的 ServletContextListener的源码也是比较简单的, Co...
布署ServletContextListener 你实现(implements)了 ServletContextListener 编译后,把它放在正确的WEB-INF/classes目录下,更改WEB-INF目录下的 web.xml文件,在web-app节点里添加 <listener> <listener-class>MyServletContextListener</listener-class> </listener> ---在不同的情况下获取数据--- spring task定时器类...

中配置的ContextListener.java类、和SessionListener.java这两个文件找不到,这两个类其实在webapps/WEB-INF/classes/listeners下,解决方法,把这两个文件拷贝到java/目录下,我在本地机器上这么做的,新建package:org.apache.classes.listeners,然后把这两个文件放进去,把web.xml中的配置改为: <listener> <listener-c...
1.web.xml中没有配置 <context-param> contextConfigLocation classpath:applicationContext.xml </context-param> <listener> <listener-class> org.springframework.web.context.ContextLoaderListener </listener-class> </listener> 2.你的jar包没导 Spring包（9个）:commons-dbcp.jar、commons-pool.j...
In addition, the "Packages," "JavaAdapter," and "JavaImporter" classes, and the "getClass" function, are not initialized. The result of this function is a scope that may be safely used in a "sandbox" environment where it is not desirable to give access to Java code from JavaScript. ...

第一种:直接将之放到/WEB-INF下,之在web.xml中声明一个listener; 第二种:将之放到classpath下,但是此时要在web.xml中加入<context-param>,用它来指明你的applicationContext.xml的位置以供web容器来加载。按照Struts2 整合spring的官方给出的档案,写成: ...
