Spring Boot 提倡使用依赖注入(Dependency Injection)的设计模式,这种模式的主要目的是解耦和提高代码的可测试性、可维护性和可扩展性。 以下是注入的一些优点: 1.解耦和模块化:通过使用依赖注入,你可以将不同的模块解耦,它们之间通过接口进行交互而不是直接依赖具体的实现类。这样可以提高代码的可维护性,并允许你更轻...

@Inject vs @Autowired in Spring Both @Inject and @Autowired annotations are used for field-based Dependency Injection in Spring. The difference between them is that @Inject is part of the Java Dependency Injection specification (JSR-330), while @Autowired is specific to Spring. In general, it...
Spring Team recommends “Always use constructor based dependency injection in your beans. Always use assertions for mandatory dependencies”. 和阿里编码规范推荐似的,Spring团队推荐又来了:总是在您的bean中使用构造函数建立依赖注入。总是使用断言强制依赖”。
simple pattern that allows dependency injection logic to run before an alternative entry point is executed. This pattern also has the advantage of working with different popular open source dependency injection frameworks. I will show the pattern using Spring Boot, Micronaut,...
