⽇志相关包 slf4j打印⽇志必须的三个依赖包
slf4j假设使⽤log4j做为底层⽇志⼯具，运⾏以上程序需要三个包：
jar、
<dependency>
<groupId>log4j</groupId>
<artifactId>log4j</artifactId>
<version>1.2.17</version>
</dependency>
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-log4j12</artifactId>
<version>1.7.21</version>
</dependency>
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-api</artifactId>
<version>1.7.21</version>
</dependency>
log4j.properties⽂件配置：
### set log levels ###
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.versionPattern=%d{yyyy-MM-dd HH:mm:ss.SSSXXX} %-5p [%t] [%C %L] %m%n
