春季注射类型之间的差异

Question

Spring中的Bean注入和依赖注入之间有什么区别，还是相同的？

Answer 1

因为在我们的上下文中依赖项是bean，所以可以说它们是相同的。

Answer 2

Any dependency that is managed by Spring is called a Spring Bean. When you register a type in Spring, when it is used as a dependency in other objects, it is injected by Spring.

On the other hand, Dependency Injection doesn't need a container like Spring. When you have a method that takes arguments, that argument is a dependency, which is a form of dependency injection instead of hard code the value of the argument in your method.
