SpringBoot2.x整合Knife4j报错 Failed to start bean 'documentationPluginsBootstrapper';

SpringBoot2.x整合Knife4j编译通过，项目启动时报错

报错信息

Failed to start bean 'documentationPluginsBootstrapper'; nested exception is com.google.common.util.concurrent.ExecutionError:***

解决办法

因为swagger依赖google的guava，而你当前项目的guava版本与之不匹配，将guava升到最新的版本
