[首先，我在一个项目中创建了一个javeEE模块，然后我可以正常启动服务器，我照常编写了代码，过了一会儿，当我再次启动tomcat服务器时，我得到了一些错误信息。
我正在网上搜索很长时间。但是没用。请帮助或尝试提供一些实现此目标的方法。非常感谢！！！
我在出现问题之前编写的代码。
File1：此文件用于测试getContextPath（）方法。
//file1
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("/responseDemo1")
public class ResponseDemo1 extends HttpServlet {
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
System.out.println("demo1...");
String contextPath = request.getContextPath();
response.sendRedirect(contextPath+"/responseDemo2");
}
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
this.doPost(request, response);
}
}
File2：
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("/responseDemo2")
public class ResponseDemo2 extends HttpServlet {
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
System.out.println("responsedemo2...");
}
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
this.doPost(request, response);
}
}
这是有效的服务器启动日志。
