如果在web.xml中配置，可以使多个url指向同一个servlet类
studentList
com.controller.StudentController
studentList
/student/list.do
studentAdd
com.controller.StudentController
studentAdd
/student/add.do
那么使用@WebServlet(" ")注解怎么使多个url都指向这个servlet呢？
比如在加个 /student/edit.do 和 /student/delete.do
试试下面这种方式：
@WebServlet({" /student/edit.do", "/student/delete.do"})
这是一个数组
String[] urlPatterns() default {}
用逗号隔开呗{"/student/delete.do","/student/edit.do"}
@WebServlet(urlPatterns{"/student/delete.do","/student/edit.do"})
