我有一个在 tomcat 7.0.29 中运行的 JSF 2.0 Web 应用程序,并尝试使用 Servlet 3.0 注释,但 servlet 不起作用,因为我看不到它的 init() 方法中写入的日志。
我已经阅读了很多相同问题的答案,但仍然没有成功。
这是我的文件的外观:
web.xml :

和小服务程序:
package utils;
import java.io.IOException;
import javax.servlet.Servlet;
import javax.servlet.ServletConfig;
import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
/**
* Servlet implementation class AjaxRelaisServlet
*/
@WebServlet("/AjaxRelaisServlet")
public class AjaxRelaisServlet extends HttpServlet {
private static final long serialVersionUID = 1L;
/**
* @see HttpServlet#HttpServlet()
*/
public AjaxRelaisServlet() {
super();
// TODO Auto-generated constructor stub
}
/**
* @see Servlet#init(ServletConfig)
*/
public void init(ServletConfig config) throws ServletException {
System.out.println("This is AjaxRelaisServlet initialisaton !!!");
}
/**
* @see HttpServlet#doGet(HttpServletRequest request, HttpServletResponse response)
*/
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
// TODO Auto-generated method stub
}
/**
* @see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse response)
*/
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
// TODO Auto-generated method stub
}
}
实际上,当我在 web.xml(注释代码)中声明它时,servlet 工作正常,但当我使用注释时却没有。顺便说一句,我想知道当这个问题得到解决时我是否可以摆脱 web.xml,但我不知道如果没有它,JSF servlet 将如何声明。
感谢帮助!
