1新建一个Servlet文件HelloWorld.java

package servlet.com;

import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public class HelloWorld extends HttpServlet{
public void doGet(HttpServletRequest request,
HttpServletResponse response) throws IOException{
PrintWriter out=response.getWriter();
out.println("<html>");
out.println("<head><title>Hello World Servlet</title></head>");
out.println("<body>");
out.println("<h1>Hello World Servlet</h1>");
out.println("</body>");
out.println("</html>");
out.close();
}
}

2配置web.xml,完成Servlet程序的映射

<servlet>
<servlet-name>hello</servlet-name>
<!--包名+类名 -->
<servlet-class>servlet.com.HelloWorld</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>hello</servlet-name>
<url-pattern>/servlet/HelloWorld</url-pattern>
</servlet-mapping>

3在浏览器中测试

http://localhost/:8080/项目名/servlet/HelloWorld(servlet-mapping中映射的地址)
