注：配置依赖，需要注意一些常见的配置：

第一种如下图<properties>属性中配置了<spring.version>标签，次标签自定义的，在<properties>属性标签中配置的属性，都可以在maven的pom文件中使用。如下图，使用方法如<dependencies>标签中的${spring.version}，表示在依赖中引入的依赖的属性值为配置中的“4.1.4.RELEASE”，在此处的含义是，映入spring-core核心包的版本是4.1.4.RELEASE。

第二种测试依赖中<scope>test<scope>标签，表示依赖项目仅仅参与测试相关的工作，包括测试代码的编译，执行。编译范围仅是测试使用。编译和运行环境不会被使用，不会被打包。

添加依赖<dependencie>，编译器右下角会有提示框，选中手动导入则每次添加依赖了都需要手动导入，选中自动导入则会后续添加依赖会自动导入。

添加jdbc.properties

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/数据库名称
jdbc.username=用户名
jdbc.password=密码
jdbc.minPoolSize=5
jdbc.maxPoolSize=20
#初始化大小
jdbc.initialSize=1
#最小
jdbc.minIdle=1
#最大
jdbc.maxActive=20
#获取连接等待超时的时间
jdbc.maxWait=60000

配置log4j.properties

### 设置###
log4j.rootLogger=debug,stdout,D,E
### 输出信息到控制抬 ###
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target=System.out
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=[%-5p] %d{yyyy-MM-dd HH:mm:ss,SSS} method:%l%n%m%n
### 输出DEBUG 级别以上的日志到=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
### 输出ERROR 级别以上的日志到=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
