idea集成jdk，tomcat，maven开发环境

新建工程：javaee web module

配置maven

配置jdk

配置工程artfacts：war exploded 设置output directory：E:\tc\test\www

配置tomcat：deployment：war exploded

为工程添加maven模块add framework support maven

建立servlet测试接口

新建servlet类文件com.Test

package com;

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

public class Test 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("helloworld");
    }
}

maven处理jar依赖pom.xml

<dependency>
            <groupId>javax.servlet</groupId>
            <artifactId>javax.servlet</artifactId>
            <version>3.0.0.v201103241009</version>
        </dependency>
