The Spring,bean can "access" each other by specifying the same or different references through the bean configuration file. 1. Beans in different XML files if it is a bean in a different XML file, you can use a "ref" tag and the "Bean" attribute to reference it."Csvoutputgenerator" or "Jsonoutputgenerator" uses the ' ref ' attribute with attribute tags-in this case, the Bean "Outputhelper" in ' Spring-commo

1 Control inversion ioc\ Dependency Injection di, because the translation is different, so there are two names.　　inversion of control means that when we call a method or class, we no longer have the initiative to create the object of this class, and control is given to others (spring).　　Dependency Injection means that spring actively creates the object of the called class, and then injects the object into o

In Spring, InitializingBean and DisposableBean are two marker interfaces, a useful way for Spring to perform certain actions upon bean initialization and destruction. for bean implemented InitializingBean, it will run afterPropertiesSet () after all bean properties have been set. for bean implemented DisposableBean, it will run destroy () after Spring container i

Many people use spring in the blog Park. net and nhib.pdf, so I also want to learn about them. This is what I wrote about nhib.pdf and spring. net is a simple example. It only implements a simple function of adding information. I do not know whether the combination is unreasonable. I hope you will criticize it. The general idea is: 1. Compile the object class

Because the most recent service item provides an interface with a requirement, all operations must check that the operation of the service is available, so the sense that AOP is particularly suitable for implementation.
