我将springBoot的项目打包成JAR然后运行时,报
IllegalStateException: Detected both log4j-over-slf4j.jar AND bound slf4j-log4j12.jar on the class path,
就是Jar包冲突了
解决方案:
在使用到的依赖包中添加<exclusion>标签将slf4j-log4j12.jar和log4j排除即可
<dependency>
<groupId>org.apache.zookeeper</groupId>
<artifactId>zookeeper</artifactId>
<version>3.4.13</version>
<exclusions>
<exclusion>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-log4j12</artifactId>
</exclusion>
<exclusion>
<groupId>log4j</groupId>
<artifactId>log4j</artifactId>
</exclusion>
</exclusions>
</dependency>
在POM文件的第三项Dependency Hierarchy
