异常信息告诉我们是jar包冲突导致,解决办法很简单,异常信息里面有个官网的地址,说明了解决方式,如下图:

访问地址:

java 复制代码
http://www.slf4j.org/codes.html#multiple_bindings

传送门:SLF4J Error Codeshttp://www.slf4j.org/codes.html#multiple_bindings

解决方式是指定使用的jar包,排除另一个不用的即可。

麻烦的是怎么找到导致jar冲突的依赖。

继续查看异常信息,提示了冲突的2个jar包的信息,如下截图:logback-classic和log4j-slf4j-impl。

查找jar依赖关系可以通过IDEA的maven插件,如下图直接搜索:

找到了相应的依赖包。

也可以通过树状结构查看,不如直接搜索来的直观:

或者通过maven命令查找:

java 复制代码
dependency:tree -Dverbose -Dincludes=ch.qos.logback

找到导致冲突的依赖jar包,问题就好解决了,我这里是spring-boot-starter-test包导致的,直接排除springboot自带的logback即可,clean后运行项目可以正常启动了。

java 复制代码
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-test</artifactId>
    <scope>test</scope>
    <!-- 排除自带的logback依赖 -->
     <exclusions>
        <exclusion>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-logging</artifactId>
        </exclusion>
    </exclusions>
</dependency>

每个项目导致的原因可能各不相同,这是我遇到的一次jar包冲突供参考。
