mybatis小试牛刀 在此基础上添加log日志。
官方文档 ： http://www.mybatis.org/mybatis-3/zh/logging.html
项目地址 ： mybatis-learning-02
0x01 测试控制台的显示内容
User(id=1, name=TOM, age=12, gender=0)
User(id=2, name=JON, age=13, gender=1)
User(id=3, name=King, age=11, gender=0)
0x02 增加日志输出
根据官方文档显示，支持的log有很多实现，这里使用Slf4j + Logback 多组合。
- 根据之前的项目，这里偷懒重新创建一个项目并把之前的代码都复制过来。
- 添加maven依赖。
<properties>

<junit.version>4.12</junit.version>
<lmbok.version>1.18.4</lmbok.version>

<h2.version>1.4.197</h2.version>
<!-- 新增内容 -->
<slf4j.version>1.7.25</slf4j.version>
<logback.version>1.2.3</logback.version>
<!-- pom文件需要指定打包编码集，[WARNING] File encoding has not been set, using platform encoding GBK, i.e. build is platform dependent! -->
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>

<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-api</artifactId>

</dependency>
<dependency>
<groupId>ch.qos.logback</groupId>
<artifactId>logback-classic</artifactId>
<version>${logback.version}</version>
</dependency>
- 添加logback配置文件
<configuration>
<appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
<!-- encoders are assigned the type
ch.qos.logback.classic.encoder.PatternLayoutEncoder by default -->
<encoder>
<pattern>z201.github.cn %d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</pattern>
</encoder>
</appender>
<root level="debug">
<appender-ref ref="STDOUT" />
</root>
</configuration>
- 再次运行单元测试。
