Idea构建maven项目:

步骤一:

步骤二:

自动导入Maven项目:

步骤三:增加web

二:搭建spring项目结构:

结构图:

网上都是一大堆的:自己也可以去搜:ssm  pom.xml   。。。。。。

1: pom.xml中的配置:

2   新建jdbc.properties文件

 driverClasss=com.mysql.jdbc.Driver
jdbcUrl=jdbc:mysql://localhost:3306/li_test
username=root
password=admin #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

3  新建log4j 配置文件
  log4j.properties

 log4j.rootLogger=INFO,Console,File

 #控制台日志
log4j.appender.Console=org.apache.log4j.ConsoleAppender
log4j.appender.Console.Target=System.out
log4j.appender.Console.layout=org.apache.log4j.PatternLayout
log4j.appender.Console.layout.ConversionPattern=[%p][%t][%d{yyyy-MM-dd HH\:mm\:ss}][%C] - %m%n #普通文件日志
log4j.appender.File=org.apache.log4j.RollingFileAppender
log4j.appender.File.File=logs/ssm.log
log4j.appender.File.MaxFileSize=10MB
#输出日志,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][%t][%d{yyyy-MM-dd HH\:mm\:ss}][%C] - %m%n
