If you define a spring configuration file, Applicationcontext.xml contains the following scan configurations:When the container starts, all the annotated classes are instantiated in the package that is being scanned. However, if the scan configuration describe

Recently, because of the work of the cause of exposure to the Bcache cache technology some fur, make a note memo.Bcache is integrated into the Linux kernel since 3.10, and several additions have been added to the later versions.Another alternative technology option is the Flashcache created by Facebook. But the author says on GitHub, the basic dare not use. This project is not actively maintained. Proceed at your own risk! In addition to providing support in the Linux 3.10 kernel, there

问题来自Linux教材，答案自我整理难免会有不足之处。这是我Linux期末的总结1. Can there be several types of partitions on a hard drive? How many can each have? (Can each partition install an operating system?) ） The hard disk partition has three types of partitions: primary partition, extended partition, logical partition, one hard disk can divide up to 4 primary partition, or 3 primary partition plus one extended partition, the extended partition can divide multiple logical partitions (up to 20).

transaction management mechanism (CMT) provided by the EJB container, which is provided by the Java EE Application Server. This allows us to simply specify which method to join the transaction, and once specified, the container will be responsible for the transaction management task. This is our way of doing civil work, because in this way we can exclude the transaction code from the logic code, and all the difficulties to the Java EE container to solve. Another benefit of using EJB CMT is that
