這篇文章主要介紹“@EnableAsync如何實現配置化日志輸出”,在日常操作中,相信很多人在@EnableAsync如何實現配置化日志輸出問題上存在疑惑,小編查閱了各式資料,整理出簡單好用的操作方法,希望對大家解答”@EnableAsync如何實現配置化日志輸出”的疑惑有所幫助!接下來,請跟著小編一起來學習吧!
聲明啟動類注解、需要import的配置類。 常規情況會額外指定一下Ordered、proxyTargetClass,本例從簡
import java.lang.annotation.Documented; import java.lang.annotation.ElementType; import java.lang.annotation.Retention; import java.lang.annotation.RetentionPolicy; import java.lang.annotation.Target; import org.springframework.context.annotation.Import; @Target(ElementType.TYPE) @Retention(RetentionPolicy.RUNTIME) @Import(LogConfigurationImport.class) @Documented public @interface EnableLog { /** * 指定包路徑 */ String[] basePackages() default {}; }
配置類中需要
