您应该在web.xml文件中声明和定义classes / servlet，如下所示：

<?xml version="1.0" encoding="UTF-8"?> <web-app version="3.0" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"> <servlet> <servlet-name>LoginForm</servlet-name> <servlet-class>com.project.system.LoginForm</servlet-class> </servlet> <servlet> <servlet-name>RegisterForm</servlet-name> <servlet-class>com.project.system.RegisterForm</servlet-class> </servlet> <servlet> <servlet-name>UserController</servlet-name> <servlet-class>com.project.controller.UserController</servlet-class> </servlet> <servlet-mapping> <servlet-name>LoginForm</servlet-name> <url-pattern>/LoginForm</url-pattern> </servlet-mapping> <servlet-mapping> <servlet-name>RegisterForm</servlet-name> <url-pattern>/RegisterForm</url-pattern> </servlet-mapping> <servlet-mapping> <servlet-name>UserController</servlet-name> <url-pattern>/UserController</url-pattern> </servlet-mapping> <session-config> <session-timeout> 30 </session-timeout> </session-config> </web-app>

You should declare and define the classes/servlets inside the web.xml file like this:
