如何解决从Tomcat 8/Library/Tomcat/work/Catalina/localhost目录中缺少的servlet类？

我创建了一个简单的应用程序，登陆到index.jsp后，用户可以单击链接并使用链接到此链接的servlet。问题是我没有看到/ Library/Tomcat/work/Catalina/localhost（index.jsp类存在）中生成的servlet类。如何解决从Tomcat 8/Library/Tomcat/work/Catalina/localhost目录中缺少的servlet类？

以下是相关文件：

的pom.xml

     </configuration> 
     </plugin> 
    </plugins> 
    <finalName>TheWebApp1</finalName> 
    </build> 
</project>

的index.jsp：

<html> 
    <head> 
     <title>My Home Page</title> 
    </head> 
<body> 
<h2>Hello World!</h2> 

Hello from index.jsp! 
Check your HelloWorld servlet <a href="HelloWorld">here</a> 
</body> 
</html>

的web.xml：

<!DOCTYPE web-app PUBLIC 
"-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" 
"http://java.sun.com/dtd/web-app_2_3.dtd" > 

<web-app xmlns="http://java.sun.com/xml/ns/javaee"

     version="3.0"> 
    <display-name>Archetype Created Web Application</display-name> 
</web-app>

HelloWorld.java：

package gui; 

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; 
import java.io.PrintWriter; 

/** 
* Created by Administrator on 12/01/15. 
*/ 
@WebServlet(name = "/HelloWorld/*") 
public class HelloWorld extends HttpServlet { 
    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { 

    } 

    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { 
     PrintWriter out = response.getWriter(); 

     out.println("<html>"); 
     out.println("<b>Hello World</b>"); 
     out.println("</html>"); 
    } 
}

我使用Tomcat Maven插件为项目的编译和部署（你可以很容易地从pom.xml文件看到）

你有没有困惑webservlet与urlpatterns的名字吗？尝试：

@WebServlet("/HelloWorld/*")

或可能：

@WebServlet(name = "HelloWorld", urlPatterns = "/HelloWorld/*")

非常感谢您！我试图使用urlPatterns，但没有这种模式。 – skiabox
