先新建一个maven的项目

1.file->new->project->next

2.maven->勾选creat from archetype->webapp,同时选择java版本->next

3.输入GroupID,ArtifacID

(在网上看到的一些解释:groupId：定义了项目属于哪个组，一般来说这个通常和公司或组织关联，比如说，你所在的公司为wk.那就应该定义为com.wk.wktest，wktest为项目名称

artifactId：定 义了当前Maven项目在组中的唯一id，例如wktest这个项目，我则把他定义为test1，还例如spring项目，他的 groupId为org.springframework，对于content项目来说artifactId则为spring-content，web项 目则为spring-web)

点击next

4.选择idea自带的maven或者本地安装好的maven，next

6.默认，不需要改 next

7.点击finish，然后项目构建结束后，点击import changes

8.检测是否成功，控制台打印Build success 说明成功

搭建ssm环境。

1结构搭建

在src下新建test文件夹，和main同级，

选中test，右键-》mark directory as-》test sources root，意思是把test设置为测试类的根目录

在main下新建文件夹resource 和web，右键-》mark directory as

将resource设置为 resources root（资源文件根目录）

将web设置为sources root（文件根目录）

在resource下新建xml文件，用来写sql

在web下新建wk，在wk下新建controller，service，serviceImpl，dao文件夹，再分别建立对应的java文件

在resource下添加配置文件applicationContext.xml，spring-mvc.xml，spring-mybatis.xml，config.properties，log4j.properties

配置pom文件 ，在<properties>节点里添加

<spring.version>4.2.6.RELEASE</spring.version><!-- mybatis版本�?--><mybatis.version>3.4.0</mybatis.version><!-- log4j日志文件管理包版�?--><slf4j.version>1.7.7</slf4j.version><log4j.version>1.2.17</log4j.version><!--jackson版本�?--><jackson.version>2.7.1</jackson.version>

找到自己写sql的xml，我的是在resource-》mapper-》test.xml

添加内容namespace绑定自己的dao的类，这个不用多说

<?xml version="1.0" encoding="UTF-8" ?><!DOCTYPE mapper PUBLIC "-////DTD Mapper 3.0//EN" "/dtd/mybatis-3-mapper.dtd" ><mapper namespace="wk.dao.TestDao"></mapper>

tomcat配置

屏幕上方点击尖头--》edit configurations

选择本地tomcat

OK，可以先跑起来，如果能正常运行并且弹出页面表示配置正确

给controller，service，serviceImpl，dao添加注解，方法，并且测试

ontroller

package wk.controller;import com.alibaba.fastjson.JSONObject;import org.slf4j.Logger;import org.slf4j.LoggerFactory;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.beans.factory.annotation.Qualifier;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RequestMethod;import org.springframework.web.bind.annotation.ResponseBody;import wk.service.TestService;/*** Created by infodba on /5/23.*/@Controller@RequestMapping("/index")public class TestController {private Logger logger = LoggerFactory.getLogger(this.getClass());@Autowired@Qualifier("testService")private TestService testService;/** 两个方法* 第一个不跳转页面，只会在页面显示出返回值* 第二个跳转页面* * */@RequestMapping(value = "/testAction", method = RequestMethod.GET)@ResponseBodypublic JSONObject indexTest(String data) {int i = testService.testAction();JSONObject jsonObject = new JSONObject();jsonObject.put("test", i);return jsonObject;}@RequestMapping(value = "/testActionDemo2", method = RequestMethod.GET)public String indexTest2() {return "home";}}

service

package wk.service;/*** Created by infodba on /5/23.*/public interface TestService {int testAction();}

serviceImpl

package wk.serviceImpl;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Service;import wk.dao.TestDao;import wk.service.TestService;/*** Created by infodba on /5/23.*/@Service("testService")public class TestServiceImpl implements TestService {@Autowired(required = false)private TestDao testDao;@Overridepublic int testAction() {int i = testDao.selectCount();return i;}}

dao

package wk.dao;/*** Created by infodba on /5/23.*/public interface TestDao {int selectCount();}

test.xml

<?xml version="1.0" encoding="UTF-8" ?><!DOCTYPE mapper PUBLIC "-////DTD Mapper 3.0//EN" "/dtd/mybatis-3-mapper.dtd" ><mapper namespace="wk.dao.TestDao"><select id="selectCount" resultType="Integer">SELECT "COUNT"(id) FROM T_PLAN</select></mapper>

index.jsp

<%@ page contentType="text/html;charset=UTF-8" language="java" %><html><head><meta charset="utf-8"><meta name="renderer" content="webkit|ie-comp|ie-stand"><meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1"><meta name="viewport"content="width=device-width,initial-scale=1,minimum-scale=1.0,maximum-scale=1.0,user-scalable=no"/><meta http-equiv="Cache-Control" content="no-siteapp"/><title>111</title></head><body><h2>Hello World!</h2><h2><a href="/testmaven/index/testAction">点---abc---击</a></h2></body></html>

在webapp下新建home.jsp

<%@ page contentType="text/html;charset=UTF-8" language="java" %><html><head><meta charset="utf-8"><meta name="renderer" content="webkit|ie-comp|ie-stand"><meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1"><meta name="viewport"content="width=device-width,initial-scale=1,minimum-scale=1.0,maximum-scale=1.0,user-scalable=no"/><meta http-equiv="Cache-Control" content="no-siteapp"/><title>222</title></head><body><h2>第二个页面</h2></body>

ok，完毕，在运行之前，将jdbc连接信息改为自己本地的数据库，同时test.xml里的sql也要改，改为自己的数据库的表

改完之后启动tomcat。
