# Java Log SLF4j simple binding demo
测试Jul binding （桥接到 Slf4j ）的场景
将原本的Logback、Jul、Jcl、log4j的输出，统一到sfl4j 并最终使用 slf4j simple 输出日志
要实现这个效果就必须引入对应日志框架的Slf4j的Over包，将日志重定向到Slf4j。但由于Slf4j 并没有一个具体的日志实现，
所以还得找一个具体的日志实现，这个demo选择的是Jul作为最终的日志实现。

## `Logback` Over 处理
`Logback` 由于使用的就是`slf4j`的接口，无法测试出是使用`Simple`还是`Logback`,因此本次不测试。
`Logback` 本身就支持`slf4j` ,因此不需要Over,直接使用就可以，也不需要引入`Logback`的依赖包,因此`Logback` Over 无法测试。
## `Jcl` Over 处理
`Jcl` 由于Spring 自己做了一个Over的包`spring-jcl`，因此如果需要测试验证，还要把这个包给排除掉。

## `Log4j2` Over 处理
`log4j2` 由于有自己的门面接口，无法通过Over方法重定向到`slf4j`，只能通过修改代码使用。
将原来的`LogManager.getLogger(LogLog4j2Tests.class)` 修改为`slf4j`的`LoggerFactory.getLogger(LogBackTests.class)`方式来改造，
这个由于需要修改代码，修改后的无法测试出是使用了`Logback`的实现还是`log4j2`的实现，这个在另外一个demo中通过不引入`Logback`来测试。
因此在这里不测试
但这样改造后就是直接实现了`slf4j`，而不是Over了。 `Log4j2`Over 无法测试
>注意不要使用`log4j-to-slf4j` 包，这个不是Over包，是把`slf4j`转换成`log4j2`的。
>不然会抛出`org.apache.logging.slf4j.SLF4JLoggerContext cannot be cast to org.apache.logging.log4j.core.LoggerContext` 异常
