如何配置安装servlet/jsp开发环境

Answer 1

要配置和使用servlet，需要一些前置条件
1、安装java运行时环境（jdk或jre）
2、安装web服务器，如tomcat
以下以tomcat环境为例讲解。

1、编写servlet类
package test.java.servelt;
import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
public class TestServlet extends HttpServlet {
protected void doGet( HttpServletRequest request, HttpServletResponse response )
throws ServletException, IOException
{
PrintWriter out = response.getWriter();
out.println( "This is a servlet TestServlet." );
out.flush();
}
}

2、web项目中的web.xml中配置

TestServlet
test.java.servlet.TestServlet

TestServlet
/testServlet

3、将servlet类编译好，放置到tomcat的文件夹下：\webapps\myapp\WEB-INF\classes\test\java\TestServlet.class，并启动tomcat

4、在浏览器中输入即可访问
