SAP Commerce開發時的Spring學習要點記錄

Spring framework

• BeanPostProcessor
• BeanFactoryPostProcessor
• AutowiredAnnotationBeanPostProcessor
• Bean： 如果用@Bean顯式指定了名稱，就用這個顯式名稱：

@Bean({"b1", "b2"}) // bean available as 'b1' and 'b2', but not 'myBean'
     public MyBean myBean() {
         // instantiate and configure MyBean obj
         return obj;
     }
      

@SpringBootApplication

@Resource

applied to a field or method, the container will inject an instance of the requested resource into the application component when the component is initialized.
applied to the component class, the annotation declares a resource that the application will look up at runtime.
