springboot整合dubbo时，会发生log4j重复加载的问题，可以查看那些依赖使用了log4j，增加sxclude排除即可

在pom.xml里面，zookeeper排除slf4j-log4j12和log4j

<!-- zookeeper -->
        <dependency>
            <groupId>org.apache.zookeeper</groupId>
            <artifactId>zookeeper</artifactId>
            <version>3.4.8</version>
            <exclusions>
                <!--排除slf4j-log4j12-->
                <exclusion>
                    <groupId>org.slf4j</groupId>
                    <artifactId>slf4j-log4j12</artifactId>
                </exclusion>
                <!--排除这个log4j-->
                <exclusion>
                    <groupId>log4j</groupId>
                    <artifactId>log4j</artifactId>
                </exclusion>
            </exclusions>
        </dependency>
