详解intellij idea搭建SSM框架(spring+maven+mybatis+mysql+junit)(上)
v博客前言
SSM（Spring+SpringMVC+MyBatis）框架集由 Spring、SpringMVC、MyBatis 三个开源框架整合而成，常作为数据源较简单的 web 项目的框架。
其中 spring 是一个轻量级的控制反转（IoC）和面向切面（AOP）的容器框架。 SpringMVC 分离了控制器、模型对象、分派器以及处理程序对象的角色，这种分离让它们更容易进行定制。 MyBatis 是一个支持普通 SQL 查询，存储过程和高级映射的优秀持久层框架。
本文旨在快速且详细的介绍 intellij idea 搭建 SSM 框架的过过程，特别适合对 SSM 框架不是很熟且感兴趣的朋友。
v准备工作
开发环境准备
- apache-tomcat-9.0 https://tomcat.apache.org/download-90.cgi
- apache-maven https://maven.apache.org/download.cgi
- MySQL https://www.mysql.com/downloads/
- workbench https://dev.mysql.com/downloads/workbench/
- Java jdk http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html
- IntelliJ IDEAhttps://www.jetbrains.com/idea/download/
对于如上这类应用的配置，网上已经有很多现成的方案了，基本操作也比较简单，这里就不再单独介绍了。配置好这些就可以开始搭建框架了。
v创建项目
点击 Next，填写 GroupId、ArtifactId（groupId 一般是域名的反写，也作为项目中类的包名，artifactId 是工程名，也就是根文件夹名）
然后 next，选择本地 maven 的位置
继续 next，选择项目保存的位置
点击 finish，他会自动生成 maven 骨架，下载所需要的 jar 包，第一次创建所需要的时间可能比较长，以后就快了，等待其完成。
创建完后的项目结构如图：
项目结构简介：
- .idea 文件夹和 helloworld.iml 是 idea 的一些配置文件，我们不用管, 就算删了也没事，当然删了，重新打开项目，就得重新配置了
- src 文件夹就是我们放项目代码的地方
- pom.xml 是 maven 的配置文件，我们需要什么 jar 包，都可以在里面添加依赖，然后 maven 就会自己帮我们下到本地仓库里面
接下来就需要创建构思项目所需的文件结构，main 下新建一个 java，用来放 java 文件，src 下新建一个 test，用来放测试文件，main 下新建一个 resources 文件夹，鼠标右键，找到 make directory as，选择 Resources root 如下图：
接下来继续完善项目结构：
- 在 main 的 java 文件夹上，鼠标右键，找到 make directory as，选择 Sources root(如上图，下同)
- 在 test 的 java 文件夹上 (如没有 java 文件，则手动创建，下同)，鼠标右键，找到 make directory as，选择 Test Sources root
- 在 test 的 resources 文件夹上，鼠标右键，找到 make directory as，选择 Test Resources root
- src->main->java 下新建 package com，再新建 package springmvc，这两个对应我们刚开始的 groupid
- springmvc 包下新建四个包，controller 包用来放前台 url 映射文件，dao 用来放与数据库的接口文件，entity 用来放实体类文件，service 用来放自己定义的接口
- applicationContext.xml 是 spring 配置文件
- sqlmap 文件夹里面放实体与数据库的映射文件
- generatorConfig.xml 和 generator.properties 是 mybatis 的配置文件
- jdbc.properties 是数据库相关信息
- log4j.properties 是日志配置文件
- webapp 下新建 css、images 等文件，用来放前端资源
- web-inf 下新建 views 文件件，jsp 文件就放这里面了
按照上面的流程修改后目录结构如下图：
v搭建 springmvc
配置 Maven pom.xml，引入 jar 包
pom.xml 主要描述了项目的 maven 坐标，依赖关系，开发者需要遵循的规则，缺陷管理系统，组织和 licenses，以及其他所有的项目相关因素，是项目级别的配置文件。

配置 log4j.properties
Log4j 是 Apache 的一个开源项目，通过使用 Log4j，我们可以控制日志信息输送的目的地是控制台、文件、GUI 组件，甚至是套接口服务器、NT 的事件记录器、UNIX Syslog 守护进程等；我们也可以控制每一条日志的输出格式；通过定义每一条日志信息的级别，我们能够更加细致地控制日志的生成过程。最令人感兴趣的就是，这些可以通过一个配置文件来灵活地进行配置，而不需要修改应用的代码。
### set log levels ###
log4j.rootLogger = INFO,D
### 输出到控制台 ###
log4j.logger.toConsole=debug,stdout
log4j.appender.stdout = org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target = System.out
log4j.appender.stdout.layout = org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern =%d{yyyy-MM-dd HH🇲🇲ss} [%5p] - %c -%F(%L) -%m%n
输出到日志文件
其中 File 可以采用绝对路径 亦可以采用相对路径 catalina.home 是 tomcat 目录 如果没有 logs 文件夹 将会报错
更加倾向于将日志文件放在 tomcat 的日志目录下 ${catalina.home}/logs/salesmanb2bError.log
绝对路径如：e:/salesmanb2bError.log
log4j.logger.daily=INFO,D
log4j.appender.D = org.apache.log4j.DailyRollingFileAppender
log4j.appender.D.File = ${catalina.home}/logs/helloworld/helloworld.log
log4j.appender.D.Append = true
log4j.appender.D.Threshold = INFO
log4j.appender.D.layout = org.apache.log4j.PatternLayout
log4j.appender.D.layout.ConversionPattern =%d{yyyy-MM-dd HH🇲🇲ss} [%5p] - %c -%F(%L) -%m%n
##log4j.logger.org.apache.ibatis=debug,stdout
##log4j.logger.java.sql=debug,stdout

配置 tomcat
到这一步 springmvc 框架就基本搭好了，我们先运行检验一下，这就需要先配置 tomcat
这里我们选择 war exploded 模式，网上关于这两个模式的解释是
war 模式—- 将 WEB 工程以包的形式上传到服务器
war exploded 模式—- 将 WEB 工程以当前文件夹的位置关系上传到服务器
on frame 换成 update classes and resources，这样修改了 jsp 页面不用重启服务器，实现热部署，然后点击 OK，效果如下图
点击绿色的启动按钮，启动项目。
正常启动，这个时候 springmvc 已经完全配置好了.
vmybatis generato
先在 spring 文件里面增加 SqlSessionFactory 配置，将下面这个配置添加到 applicationContext.xml 文件里面

请注意的是上面的 classPathEntry 节点的 location 属性值是本地的 mysql-connector-java.jar 的位置，因为连接数据库是需要驱动的，我们用 maven 已经自动帮我们下好了 jar 包，在左边的 External Libraries 里面寻找 JAR 包的路径。
按照上面的 Ctrl+c and Ctrl+v, 配置好 mysql jar 包的本地路径.
配置 generator.properties
这里面保存的是连接数据库的相关信息，是在使用 mybatis-generator 这个功能的时候用到的；其实在 jdbc.properties 是系统运行时用到的。这两个信息差不多，图方便的话，也可以将两个合并成一个文件，分开写的话，好实现可插拔。
driver=com.mysql.jdbc.Driver url=jdbc:mysql://localhost:3306/mytest?useUnicode=true&characterEncoding=utf-8 username=root password=*********#entity 包名和 java 目录
modelPackage=com.springmvc.entity
modelProject=src/main/java
#sqlmap 包名 和 resources 目录
sqlPackage=sqlmap
sqlProject=src/main/resources
#mapper 包名和 java 目录
mapperPackage=com.springmvc.dao
mapperProject=src/main/javatable=message
modelPackage 是等会连接数据库自动生成的实体类保存的位置，sqlPackage 是生成 xml 映射文件保存的位置，mapperPackage 是生成数据库接口保存的位置，table 是数据库里面的表的名字
创建数据表
这样，我们需要再 mytest 数据库里创建一个测试用的表。
use mytest; CREATE TABLE `message` ( `id` int(10) unsigned NOT NULL AUTO_INCREMENT, `command` varchar(30) NOT NULL, `description` varchar(30) NOT NULL, `content` varchar(30) NOT NULL, PRIMARY KEY (`id`) )ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8;select * from message;
mybatis 基本配置的差不多了，执行 maven 的 mybatis-generator 操作，尽管双击便是。
当日志中提示 "BUILD SUCCESS" 意为生成 mybatis 成功，成功以后会对应成圣 mapper.xml、dao 层和 entity 层的文件，具体效果见下图：
（更新：有朋友私信说右侧没有这些功能栏，可以通过 view->tool buttons 打开）
v配置 junit
如果写完一段代码，想去验证他的正确性，并不一定需要去启动 tomcat 跑跑看或者 debug，这时我们就会想到可以使用测试工具来验证，这儿配置 junit 测试。 那就来测试一下刚生成的 message 接口有没有用，因为 spring 的标签，我们先去 messagemapper 文件加一个 @Repository 标签，表明它是数据访问组件, 即 DAO 组件
如下图：
接下来就可以新建测试文件开始测试，将鼠标移到 MessageMapper 后 (箭头所指方向)，然后键盘上按下快捷键 alt+enter 键，接着 create test
如下图：
选中需要测试的函数方法，点击 OK，
如下图：
之后会在 test 目录下生成 MessageMapperTest 测试文件，如下图：
测试就开始编写 MessageMapperTest，编写测试代码。
package com.springmvc.dao;import com.springmvc.entity.Message;
import org.junit.After;
import org.junit.Before;
import org.junit.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;import static org.junit.Assert.*;
/**
Created by toutou on 2018/5/10.
*/
public class MessageMapperTest {private ApplicationContext applicationContext;
@Autowired
private MessageMapper mapper;@Before
public void setUp() throws Exception {
// 加载 spring 配置文件
applicationContext = new ClassPathXmlApplicationContext("classpath:spring/applicationContext.xml");
// 导入需要测试的
mapper = applicationContext.getBean(MessageMapper.class);
}@After
public void tearDown() throws Exception {
}@Test
public void insert() throws Exception {
Message message = new Message();
message.setCommand("吃饭");
message.setContent("睡觉");
message.setDescription("打豆豆");
int result = mapper.insert(message);
System.out.println(result);
assert (result == 1);
}
}
OK，这样就完成了测试类的编码，接下来运行 test，右击这个绿色的小三角，然后运行。
如下图：
运行之后效果图：
OK，运行之后，返回 1，表示运行成功。
那么我们到数据库看看吃饭睡觉打豆豆有没有被插入数据库。
OK，大功告成。

v博客总结
本篇博文只是介绍一个 SSM 框架搭建，本来想着一鼓作气把 SSM 写完的。只是很多细节的东西我还是尽量介绍到位，这就导致这边博文已经很长，加之夜深了，所以还是给标题加了个 "上" 集，至于引入 spring mvc 前后台交互的还是留到下集再说吧。欢迎查阅本文的精彩后续
