idea搭建ssm項目

很久沒有自己搭過ssm框架了，最近需要學習Activity看到需要整合到ssm框架裏，所以先搭個ssm框架。

開發環境

jdk1.8+tomcat8+idea2018.2.4

新建maven項目

到這裏爲止一個maven項目就創建好了

但是使用idea自動生成的maven項目並不完整，需要自己手動創建一些目錄，這是最終的ssm項目目錄

jdbc.properties

driver=com.mysql.jdbc.Driver
url=jdbc:mysql://localhost:3306/test
username=root
password=123456
#定義初始連接數
initialSize=0
#定義最大連接數
maxActive=20
#定義最大空閒
maxIdle=20
#定義最小空閒
minIdle=1
#定義最長等待時間
maxWait=60000

log4j.properties

#定義LOG輸出級別
log4j.rootLogger=INFO,Console,File
#定義日誌輸出目的地爲控制檯
log4j.appender.Console=org.apache.log4j.ConsoleAppender
log4j.appender.Console.Target=System.out
#可以靈活地指定日誌輸出格式，下面一行是指定具體的格式
log4j.appender.Console.layout = org.apache.log4j.PatternLayout
log4j.appender.Console.layout.ConversionPattern=[%c] - %m%n

#文件大小到達指定尺寸的時候產生一個新的文件
log4j.appender.File = org.apache.log4j.RollingFileAppender
#指定輸出目錄
log4j.appender.File.File = logs/ssm.log
#定義文件最大大小
log4j.appender.File.MaxFileSize = 10MB
# 輸出所以日誌，如果換成DEBUG表示輸出DEBUG以上級別日誌
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
