我在idea中建立maven项目，但是报错

java.lang.IllegalStateException: Detected both log4j-over-slf4j.jar AND bound slf4j-log4j12.jar on the class path, preempting StackOverflowError

看了一下，我的pom.xml里面是这么写的

<dependency>  <groupId>org.apache.logging.log4j</groupId>  <artifactId>log4j-api</artifactId>  <scope>runtime</scope></dependency><dependency>  <groupId>org.apache.logging.log4j</groupId>  <artifactId>log4j-core</artifactId>  <scope>runtime</scope></dependency><dependency>  <groupId>org.apache.logging.log4j</groupId>  <artifactId>log4j-slf4j-impl</artifactId>  <scope>runtime</scope></dependency>

我们只需要改成如下即可，

<dependency>

<groupId>org.slf4j</groupId>

<artifactId>slf4j-log4j12</artifactId>

<version>1.6.1</version>

<scope>runtime</scope>

<exclusions>

<exclusion>

<groupId>org.slf4j</groupId>

<artifactId>slf4j-log4j12</artifactId>

</exclusion>

<exclusion>

<groupId>log4j</groupId>

<artifactId>log4j</artifactId>

</exclusion>

</exclusions>

</dependency>

用下面这部分替换上面的
