绕过/*,web.xml直接访问jsp

复制提示
web.xml中如果配置了/* 全匹配,那么不能用servet去响应页面返回了,因为全都被会/*拦截.
<servlet>
<servlet-name>validateAuth</servlet-name>
<servlet-class>com.testdemo.validate.control.ValidateControl</servlet-class>
</servlet> <servlet-mapping>
<servlet-name>validateAuth</servlet-name>
<url-pattern>/*</url-pattern>
</servlet-mapping>
所以这个时候我们可以使用
<jsp-file>/jsp/index.jsp</jsp-file> 直接通过web.xml配置直连jsp页面.
<servlet>
<servlet-name>jsp1</servlet-name>
<jsp-file>/jsp/index.jsp</jsp-file>
</servlet> <servlet-mapping>
<servlet-name>jsp1</servlet-name>
<url-pattern>/jsp/index.jsp</url-pattern>
</servlet-mapping> <servlet>
<servlet-name>validateAuth</servlet-name>
<servlet-class>com.testdemo.validate.control.ValidateControl</servlet-class>
</servlet> <servlet-mapping>
<servlet-name>validateAuth</servlet-name>
<url-pattern>/*</url-pattern>
</servlet-mapping>
