凝视类型 @WebFilterSort
须要用的jar包 http://download.csdn.net/detail/u013202238/9431110
用该注解注冊的Filter默认在部署描写叙述符中的过滤器载入后载入,能够使用isMatchAfter更改载入顺序
为Filter排序注解,排序从1開始,1优先级最高
以url-pattern 过滤的最先运行,以servlet-name 过滤的在所有url-pattern运行后运行
在web.xml中设置參数
< context-param>
< description>被扫描的过滤器的所在包< /description>
< param-name>filterPackage< /param-name>
< param-value>com.test.filter.pack< /param-value>
< /context-param>
filterPackage 必填,包范围越小越好
filterInitScanJar 选填
是否扫描jar包中的类,默觉得false不扫描,假设不打印能够不配置该參数
filterInitDebug 选填
是否打印过滤器初始化信息(按排序顺序),默认false不打印,假设不打印能够不配置该參数
