idea springboot启动报SLF4J:Failed to load class “org.slf4j.impl.StaticLoggerBinder”「建议收藏」

大家好，又见面了，我是你们的朋友全栈君。

首先声明一下，我用的 Intellij IDEA 2018.3 版本的，springboot的版本是 2.0.5.RELEASE 版本。

当我喜滋滋的编写完测试代码，点击 Debug 的时候，睁大眼睛看控制台简直是看得一脸懵逼，控制台显示如下：

SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.

没错，就是这么点日志，但是注意 第一行 SLF4J: Failed to load class “org.slf4j.impl.StaticLoggerBinder”.

然后去 http://www.slf4j.org/codes.html#StaticLoggerBinder 地址看了下解决方法，这里我就不详细说了，反正大概意思就加上slf4j-nop.jar slf4j-simple.jar， slf4j-log4j12.jar，slf4j-jdk14.jar或 logback-classic.jar中的其中一个jar包就行（只能是一个，多了就会有冲突）。

于是乎我加了 slf4j-simple jar包代码如下：（这段代码是我直接从线上maven库中copy出来的，肯定不会有错）

代码语言：javascript复制
<dependency>
    <groupId>org.slf4j</groupId>
    <artifactId>slf4j-simple</artifactId>
    <version>1.7.25</version>
    <scope>test</scope>
  </dependency>

引入依赖后，启动还是报错，一模一样，这TM就有点过分了，官网的解决方法一般是不会出错的，而且之前我也百度过，也是差不多一样的做法，那到底是什么问题呢？

于是又是一顿找，看看前辈们有没有碰到过类似的错误，终于有所发现，最终修改代码如下：

代码语言：javascript复制
<dependency>
    <groupId>org.slf4j</groupId>
    <artifactId>slf4j-simple</artifactId>
    <version>1.7.25</version>
    <scope>compile</scope>
  </dependency>

没错，就是毁在这段代码上 <scope>test</scope> ，test表示只有在测试环境下，才可以使用，而我springboot是运行在main方法中，是不属于测试环境，所以这个包就相当于没有加入依赖，也就没有被加载到。改成compile则表示编译的时候就会加载此jar包，那么最后就运行成功了，成功的日志如下：

这日志看上去就正常了。

当然这只是我的解决方法，也许是我的粗心大意吧！如果你也遇到了这种情况可以不妨一试吧。
