使用IDEA 新建Maven项目

这里使用IDEA提供WEB的模板

GroupId 是项目工程的Id
ArtifactId是模块的Id
一个项目工程Id下可以有多个模块Id

这是Maven配置 需要IDEA先配置好Maven

Finish

配置Maven

配置maven home directory 以及配置文件的路径
并在maven配置文件setting.xml的相应位置添加阿里云的镜像，避免使用默认的国外镜像导致下载速度过慢

<mirror>
  <id>alimaven</id>
  <name>aliyun maven</name>
  <url>http://maven.aliyun.com/nexus/content/groups/public/</url>
  <mirrorOf>central</mirrorOf>        
</mirror>

通过Maven配置SSM框架的依赖

在pom.xml中添加相应配置

调整项目目录结构

刚创建的Maven项目目录结构是这样的

调整后

注意用 make directory as 修改目录结构

添加各种框架配置

在resources文件夹下新建jdbc.properties 配置数据库连接

driver=com.mysql.jdbc.Driver
url=jdbc:mysql://localhost:3306/db
username=root
password=123456
#定义初始连接数
initialSize=0
#定义最大连接数
maxActive=20
#定义最大空闲
maxIdle=20
#定义最小空闲
minIdle=1
#定义最长等待时间
maxWait=60000

新建log4j.properties

#定义LOG输出级别
log4j.rootLogger=INFO,Console,File
#定义日志输出目的地为控制台
log4j.appender.Console=org.apache.log4j.ConsoleAppender
log4j.appender.Console.Target=System.out
#可以灵活地指定日志输出格式，下面一行是指定具体的格式
log4j.appender.Console.layout = org.apache.log4j.PatternLayout
log4j.appender.Console.layout.ConversionPattern=[%c] - %m%n

#文件大小到达指定尺寸的时候产生一个新的文件
log4j.appender.File = org.apache.log4j.RollingFileAppender
#指定输出目录
log4j.appender.File.File = logs/ssm.log
#定义文件最大大小
log4j.appender.File.MaxFileSize = 10MB
# 输出所以日志，如果换成DEBUG表示输出DEBUG以上级别日志
log4j.appender.File.Threshold = ALL
log4j.appender.File.layout = org.apache.log4j.PatternLayout
log4j.appender.File.layout.ConversionPattern =[%p] [%d{yyyy-MM-dd HH\:mm\:ss}][%c]%m%n

新建spring-myBatis.xml 这是整合spring和MyBatis的配置文件

SSM框架基本配置完成了

简单测试运行下

点击右上角Edit Configuration 添加Tomcat（需先配置好Tomcat）

再添加Tomcat Service Local，点到Deployment 添加Artfact

点击运行，就可以测试了，不过测试需要写一些内容，不然会报错
