springboot禁用 log

Caused by: java.lang.IllegalArgumentException: LoggerFactory is not a Logback LoggerContext but Logback is on the classpath. Either remove Logback or the competing implementation (class org.slf4j.impl.Log4jLoggerFactory loaded from file:/home/linkedcare/spark-2.2.0-bin-hadoop2.6/jars/slf4j-log4j12-1.7.16.jar). If you are using WebLogic you will need to add ‘org.slf4j’ to prefer-application-packages in WEB-INF/weblogic.xml: org.slf4j.impl.Log4jLoggerFactory

你可以将排除项添加到spring-boot-starter和spring-boot-starter-web以解决冲突：

org.springframework.boot spring-boot-starter org.springframework.boot spring-boot-starter-logging org.springframework.boot spring-boot-starter-web org.springframework.boot spring-boot-starter-logging
