注：配置依賴，需要注意一些常見的配置：

第一種如下圖<properties>屬性中配置了<spring.version>標籤，次標籤自定義的，在<properties>屬性標籤中配置的屬性，都可以在maven的pom文件中使用。如下圖，使用方法如<dependencies>標籤中的${spring.version}，表示在依賴中引入的依賴的屬性值爲配置中的“4.1.4.RELEASE”，在此處的含義是，映入spring-core核心包的版本是4.1.4.RELEASE。

第二種測試依賴中<scope>test<scope>標籤，表示依賴項目僅僅參與測試相關的工作，包括測試代碼的編譯，執行。編譯範圍僅是測試使用。編譯和運行環境不會被使用，不會被打包。

添加依賴<dependencie>，編譯器右下角會有提示框，選中手動導入則每次添加依賴了都需要手動導入，選中自動導入則會後續添加依賴會自動導入。

添加jdbc.properties

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/數據庫名稱
jdbc.username=用戶名
jdbc.password=密碼
jdbc.minPoolSize=5
jdbc.maxPoolSize=20
#初始化大小
jdbc.initialSize=1
#最小
jdbc.minIdle=1
#最大
jdbc.maxActive=20
#獲取連接等待超時的時間
jdbc.maxWait=60000

配置log4j.properties

### 設置###
log4j.rootLogger=debug,stdout,D,E
### 輸出信息到控制擡 ###
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target=System.out

log4j.appender.stdout.layout.ConversionPattern=[%-5p] %d{yyyy-MM-dd HH:mm:ss,SSS} method:%l%n%m%n
### 輸出DEBUG 級別以上的日誌到=E://logs/log.log ###
log4j.appender.D=org.apache.log4j.DailyRollingFileAppender
#log4j.appender.D.File = E://logs/log.log
log4j.appender.D.Append=true
log4j.appender.D.Threshold=DEBUG
log4j.appender.D.layout=org.apache.log4j.PatternLayout
log4j.appender.D.layout.ConversionPattern=%-d{yyyy-MM-dd HH:mm:ss}  [ %t:%r ] - [ %p ]  %m%n
### 輸出ERROR 級別以上的日誌到=E://logs/error.log ###
log4j.appender.E=org.apache.log4j.DailyRollingFileAppender
#log4j.appender.E.File =E://logs/error.log
log4j.appender.E.Append=true
log4j.appender.E.Threshold=ERROR
log4j.appender.E.layout=org.apache.log4j.PatternLayout
log4j.appender.E.layout.ConversionPattern=%-d{yyyy-MM-dd HH:mm:ss}  [ %t:%r ] - [ %p ]  %m%n
