Note: The configuration is dependent, and some common configurations need to be paid attention to:

 

The first type is configured with the <spring.version> tag in the <properties> property as shown in the figure below. The properties configured in the <properties> property tag of the secondary tag are customizable and can be used in the maven pom file. As shown in the figure below, the usage method is like ${spring.version} in the <dependencies> tag, which means that the attribute value of the dependency introduced in the dependency is "4.1.4.RELEASE" in the configuration. The meaning here is to reflect The version of the spring-core core package is 4.1.4.RELEASE.

The <scope>test<scope> tag in the second type of test dependency indicates that the dependent project only participates in test-related work, including the compilation and execution of test code. The scope of compilation is only for testing. The compilation and runtime environment will not be used and will not be packaged.

Add dependency <dependencie>, there will be a prompt box in the lower right corner of the compiler. If you select manual import, you need to manually import it every time you add a dependency. If you select automatic import, subsequent dependencies will be automatically imported.

Add 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

Configure 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.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.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
