Caused by: java.lang.IllegalArgumentException: Invalid <url-pattern> servlet/item/ShowAddItemServlet in servlet mapping
严重: Parse error in application web.xml file at jndi:/localhost/drp3.6/WEB-INF/web.xml
java.lang.IllegalArgumentException: Invalid <url-pattern> servlet/item/ShowAddItemServlet in servlet mapping
at org.apache.tomcat.util.digester.Digester.createSAXException(Digester.java:2806)
……
错误原因:非法的<url-pattern>表达式
应将<url-pattern> servlet/item/ShowAddItemServlet
改为:<url-pattern> /servlet/item/ShowAddItemServlet
即如果有虚拟的文件夹,那么文件夹前要加斜杠“/”
<servlet-mapping>
<servlet-name>spring</servlet-name>
<url-pattern>*.do</url-pattern>//这里不要前面的 '/'
</servlet-mapping>
