@WebServlet(”/myservlet”)
@WebServlet(name=”MyServlet”, urlPatterns={"/myservlet", "/bar"})
xxx/myservlet就可用执行该servlet，而不需要在原来的web.xml配置servlet-name、servlet-class、url-pattern
@WebFilter(urlPatterns="/*",
initParams={@WebInitParam(name="ignore",value = "/action/,/commons/")})
类似于
| <init-param> |
| <param-name>ignore</param-name> |
|
<param-value>/action/,/common/</param-value> |
| </init-param> |
