超简单的servlet配置

1.在web.xml中加上
<servlet-mapping>
        <servlet-name>invoker</servlet-name>
        <url-pattern>/servlet/*</url-pattern>
    </servlet-mapping>

当然也可以这样配置
<servlet-mapping>
        <servlet-name>invoker</servlet-name>
        <url-pattern>/tjjtds/*</url-pattern>
    </servlet-mapping>
调用时注意路径就可以了

2.测试代码Hello.java

package my;

import java.io.*;
import java.util.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class Hello extends HttpServlet {


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

        out.println("hello world");
        
    }
}


3.

 把Hello.java放到classes/my下
 classes/my/Hello.java
 调用时web容器自动编译(resin2.*会自动编译，tomcat不行)
http://127.0.0.1/web-app-name/servlet/my.Hello
http://127.0.0.1:port/web-app-name/servlet/my.Hello

http://127.0.0.1:port/web-app-name/servlet/your_servlet_class_name
