在将Main class 设置primarySources后,调用了WebApplicationType.deduceFromClasspath()方法,该方法是为了检查当前的应用类型,并设置给webApplicationType。 我们进入deduceFromClasspath方法 : staticWebApplicationTypededuceFromClasspath(){if(ClassUtils.isPresent(WEBFLUX_INDICATOR_CLASS,null)&&!ClassUtils.isPresent(WEBMVC...
One of the steps in a successful boot sequence is to mount the overlay file system with a hook setup by (/rom)/lib/preinit/80_mount_root to call mount_root which if extroot is not configured, mounts the writable data partition “rootfs_data” as overlay over the / partition “rootfs”...
