Overview It is not difficult to find out from the name of the interface that the function of Initializingbean is to perform a custom operation after the bean is initialized. The beans in the spring container are life-cycle, and spring allows specific operations to be performed after the bean has been initialized and before the bean is destroyed, with the following three common settings: by implementing the Initializingbean/disposablebean interface to Custom initialization/destruction before/aft

Features OverviewThe init process is the first process launched by the Android kernel, with a process number (PID) of 1, which is the ancestor of all the processes in the Android system, so it is shouldering the important responsibility of system startup.
