first, in the board file Client the instantiation ofDefines the device information in the initialization of the kernel, such as in a board file. The premise of this operation is that when the kernel compiles, it is determined which i²c devices and their addresses , as well as the number of the connected bus .For example, in the board file/arch/arm/mach-xxx/board_xxx.c can be used similar to the following code to register the I²C device information.1.

This article focuses on four ways to instantiate beans (injection mode) or four ways to instantiate a dependent object. The above program, which creates the Bean object, uses the method of the constructor (Spring can create the class object in the case of privatization of the constructor)There are four common ways to create these types of methods:1) Setter method2) constructor function3) Static Factory4) In

However, beans are used. instantiate () will negatively affect the performance, because this method will search for a serialized version of the object on the file system, that is, the same name as the class to
