Servlet配置方式与注解方式

配置方式

<servlet>
        <servlet-name>Userinfo</servlet-name>
        <servlet-class>com.cloudwise.jsp.jsp02.homework.UserInfoServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>Userinfo</servlet-name>
        <url-pattern>/Userinfo</url-pattern>
    </servlet-mapping>

注解方式

 

import javax.servlet.annotation.WebServlet;
//注解urlPatterns = {"/user","/book"} 一个参数可以不带花括号
@WebServlet(urlPatterns = {"/user","/book"},loadOnStartup = 1)
public class servlet {

}
