spring-boot預設使用logback作為日誌框架 要配置log4j，要在各種starter中排除logging依賴 新增 log4j依賴 如: compile ('org.springframework.boot:spring-boot-starter-web'){ exclude module: 'spring-boot-starter-logging' } compile ('org.springframework.boot:spring-boot-starter-data-redis'){ exclude module: 'spring-boot-starter-logging' } compile ('org.springframework.boot:spring-boot-starter-activemq'){ exclude module: 'spring-boot-starter-logging' } compile( 'org.springframework.boot:spring-boot-starter-log4j2:1.5.7.RELEASE', ) 然後在classspath中新增 log4j2.xml
