如何在Struts2中使用Servlet

<servlet>
    <servlet-name>MyServlet</servlet-name>
    <servlet-class>com.example.MyServlet</servlet-class>
</servlet>
<servlet-mapping>
    <servlet-name>MyServlet</servlet-name>
    <url-pattern>/myservlet</url-pattern>
</servlet-mapping>

<action name="myAction" class="com.example.MyAction">
    <result>/myservlet</result>
</action>

public class MyAction extends ActionSupport {
    public String execute() {
        // 调用Servlet的doGet或doPost方法
        HttpServletRequest request = ServletActionContext.getRequest();
        HttpServletResponse response = ServletActionContext.getResponse();
        MyServlet servlet = new MyServlet();
        servlet.doGet(request, response);
        return SUCCESS;
    }
}
