Use @ Resource annotation to complete attribute assembly and @ resource annotation assembly Use Field Injection (for annotation): Injection dependent objects can be manually or automatically assembled. Manual assembly is recommended in practical applications, because automatic assembly will produce unknown conditions and developers cannot predict the final assemb

Spring annotation @ Resource and @ Autowired, springautowired Annotation Spring not only supports the @ Autowired annotation defined by itself, but also supports several annotations defined by the JSR-250 specification, such as: @ Resource, @ PostConstruct and @ PreDestroy. 1. @ Autowired is provided by Spring. You need to import Package: org. springframework. be

The core function of the Spring framework, IoC (Inversion of Control), is to manage objects through Spring containers and map the composite relationships between objects. We usually declare the action, service, dao, and other layers in the xml configuration file, and then inform the framework of the injection method we want, then declare the get and set methods of the combined classes in the class. The Application of annotations in the Spring framework mainly solves such problems. Another core k
