1. Servlet程序页面的修改

如果需要将页面输出的内容修改为Hello Servlet，仅仅修改 .java 文件是不能实现的，还需要重新打包，重新部署，重新运行Tomcat，再次访问才可以实现；

现重建HelloServlet2项目，并置servlet path为HelloServlet2，

其中.java文件内容如下：

java 复制代码

import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;

@WebServlet("/hello2")
public class HelloServlet2 extends HttpServlet {
    @Override
    protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
        System.out.println("Hello Servlet");
        resp.getWriter().write("Hello Servlet");
    }
}

pom.xml文件内容如下：
