Spring Boog引入ZooKeeper启动报错

在Spring Boot中引入ZooKeeper的jar包，启动时报错，如图：

是slf4j日志包冲出导致，因为项目在spring-boot-starter-logging中已引入。

解决办法，排除ZooKeeper中slf4j的依赖：

<dependency>
    <groupId>org.apache.zookeeper</groupId>
    <artifactId>zookeeper</artifactId>
    <version>${zookeeper.version}</version>
    <exclusions>
        <exclusion>
            <artifactId>slf4j-log4j12</artifactId>
            <groupId>org.slf4j</groupId>
        </exclusion>
    </exclusions>
</dependency>
