完整地配置一个Servlet需要的标签是()。
A: <;webapp>;<;/webapp>;
B: <;servlet>;<;/servlet>;和<;servlet-mapping>;<;/servlet-mapping>;
C: <;servlet-name/>;和<;servlet-class>;
D: <;servlet-mapping >;<; servlet-name>;
A: <;webapp>;<;/webapp>;
B: <;servlet>;<;/servlet>;和<;servlet-mapping>;<;/servlet-mapping>;
C: <;servlet-name/>;和<;servlet-class>;
D: <;servlet-mapping >;<; servlet-name>;
举一反三
- 在浏览器中输入http://localhost:8080/myWebApp/start/,就会调用itcast包中名为Student的Servlet,那么在web.xml中配置正确的是(): <servlet> <servlet-name> itcast.Student </servlet-name> <servlet-value> /start/*</servlet-class> </servlet>|<servlet> <servlet-name>/start/*</servlet-name> <servlet-value>itcast.Student</servlet-class> </servlet>|<servlet> <servlet-name>itcast.Student </servlet-name> <servlet-value>student </servlet-class> </servlet> <servlet-mapping> <servlet-name> itcast.Student </servlet-name> <url-pattern>/start/*</url-pattern> </servlet-mapping>|<servlet> <servlet-name>student</servlet-name> <servlet-class>itcast.Student</servlet-class> </servlet> <servlet-mapping> <servlet-name>student</servlet-name> <url-pattern>/start/*</url-pattern> </servlet-mapping>
- 中国大学MOOC: 下面是一个 Servlet 部署文件的片段: <servlet> <servlet-name>Hello</servlet-name> <servlet-class>myservlet.example.FirstServlet</servlet-class> </servlet> <servlet-mapping> <servlet-name>Hello</servlet-name> <url-pattern>/helpHello</url-pattern> </servlet-mapping> Servlet 的类名是( )
- 假设在myServlet应用中有一个MyServlet类,在web.xml文件中对其进行如下配置: <servlet> <servlet-name> mysrvlet </servlet-name> <servlet-class> com.wgh.MyServlet </servlet -class> </servlet> < servlet-mapping> <servlet -name> myservlet </servlet-name> <servlet-pattern> /welcome </url-pattern> </servlet-mapping> 则以下选项可以访问到MyServlet的是( )
- 下列选项中,可以填入横线处的是() (多选) <servlet> <servlet-name>LoginServlet</servlet-name> <servlet-class>com.itcast.youjun.servlet.LoginServlet</servlet-class> </servlet> <servlet-mapping> <servlet-name>LoginServlet</servlet-name> <url-pattern>________</url-pattern> </servlet-mapping>
- 部署Servlet需要在部署描述文件中添加哪两个元素 A: <;servlet>;,<;servlet-config>; B: <;servlet-name>;,<;url-pattern>; C: <;servlet>;,<;servlet-mapping>; D: <;servlet-class>;,<;servlet-mapping>;
