SpringMVC+Spring+Mybatis實現最簡單的登入驗證

1.匯入專案相關的jar包

2.建立專案結構

3.組態檔的設定及程式碼

db.properties:

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://127.0.0.1:3306/test1
jdbc.username=root
jdbc.password=
#定義初始連線數
jdbc.initialSize=0
#定義最大連線數
jdbc.maxActive=20
#定義最大空閒
jdbc.maxIdle=20
#定義最小空閒
jdbc.minIdle=1
#定義最長等待時間
jdbc.maxWait=60000

log4j.properties:

#定義LOG輸出級別
log4j.rootLogger=INFO,Console,File
#定義紀錄檔輸出目的地為控制台
log4j.appender.Console=org.apache.log4j.ConsoleAppender
log4j.appender.Console.Target=System.out
#可以靈活地指定紀錄檔輸出格式，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
#檔案大小到達指定尺寸的時候產生一個新的檔案
log4j.appender.File = org.apache.log4j.RollingFileAppender
#指定輸出目錄
log4j.appender.File.File = logs/ssm.log
#定義檔案最大大小
log4j.appender.File.MaxFileSize = 10MB
# 輸出所以紀錄檔，如果換成DEBUG表示輸出DEBUG以上級別紀錄檔
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
