After that, we must call the jar from the same directory as the manifest file, as follows:Jar CFM Bangbean.jar BANGBEAN.MF BangbeanThis example assumes that we want to produce a file named Bangbean.jar and we put the list in a file called BANGBEAN.MF.We might think, "What happens to the other classes that come when I compile Ba

Spring core learning (5) inject beans into Bean-Parse dependencies, beanbean- Preface: start to learn the core idea of Spring and learn it through a simplified version of Spring code. Content: 1. BeanReference-save Bean reference. 2. Call createBean ()-lazy-init in getBean. This time we used Bean injection in Bean. Here we have rewritten AbstractBeanFactory again. After rewriting, AbstractBeanFactory will have an additional
