SLF4j的功能就是充当一个门面，有点类似于jdbc，用class.forName的方式加载当前pom文件中引入的实现类。可以看看这个blog的分析，省的自己看源码了（https://blog.csdn.net/u010644448/article/details/50298275）
springBoot不用引入依赖，logback和slf4j的jar被依赖传递过来了。只需要配置一个logback.xml文件即可。

Logger根节点与其他logger的关系
-
<logger>中没配置level时，会继承父级的level - 没有配置additivity属性时，默认该属性为true，表示此
<logger>的打印信息向父级传递 - 没有配置
<appender-ref>，表示此去<logger>不会打印出任何信息
logger的子父级关系
例子 ： <logger> 中 name="java" 是 name ="java.lang"的父级，<root>是所有<logger>的父级。
shang
appender
<appender>是<configuration>的子节点，是负责写日志的组件。<appender>有两个必要属性name和class：
- name指定
<appender>的名称 - class指定
<appender>的权限定名
其子节点的介绍：
-
<file>表示写入的文件名，可以使相对目录也可以是绝对目录，如果上级目录不存在则自动创建 -
<appender>如果为true表示日志被追加到文件结尾，如果是false表示清空文件 -
<prudent>如果为true表示日志会被安全地写入文件，即使其他的FileAppender也在向此文件做写入操作，效率低，默认为false
多种appender（基于时间的）可以看这篇blog**https://juejin.im/post/5a39c91cf265da4327185d10

springBoot内置了slf4j和logback，不需要引入额外的jar包
