Spring (4) Bean injection (Spring Bean injection)1. constructor Injection Definition: You can use constructors to set dependencies. Advantages and disadvantages: Complete dependency creation while constructing objects If there are many associated objects, you have to add too many parameters to the constructor. Base ind

It is similar to calling a statement:Memoryuserdao Userdao = new Memoryuserdao ().The id attribute must be a valid XML ID, which means that it must be unique throughout the XML document. It is a "lifetime code" for a Bean. You can also use the Name property to define one or more individual na

Sometimes you need to get a spring bean object on your own as needed in your new object, or in some Util method or property, to do some work, but because your new object and Util method are not managed by spring, if you use it directly on the property that you depend on @Autowiredyou will be able to report an error that cannot be injected, or it will not be repor

The design principle of spring is to use as many instances as possible and as many single-State instances as possible, which can be seen from its bean configuration file. However, sometimes injection is not the best solution, especially for the processing of legacy classes. Static classes may be a better solution, because static classes do not need to be injected, there is no need to change the original cod
