根据ILoggerFactory 获取 Logger SLF4J 要求日志实现 jar 包都要实现 StaticLoggerBinder 这个类,而且要放在指定目录:org/slf4j/impl/StaticLoggerBinder.class,SLF4J 的LoggerFactory会去扫描所有 jar 包中的这个地址,参考下面的代码。 private static String STATIC_LOGGER_BINDER_PATH = "org/slf4j/impl/StaticLogg...
然而,有时候我们可能会遇到一个问题,即在某些环境中,自动生成的日志记录器对象缺少了info方法。这可能会导致编译错误或运行时错误。那么,为什么会出现这个问题呢?这是因为Lombok的@Slf4j注解默认使用的是Java Util Logging (JUL)作为日志记录器的实现。而JUL的日志记录器对象并不一定都包含info方法。
