is it mandatory to write a setter function when we use @Inject annotation

CodePudding user response：

Nope. It is not mandatory. Reflection is used to set the value.

See this and this for more info.

No, we don,t have to write the setter method for @Inject, it is same annotation as the @Autowired.

@Inject is part of a Java technology called CDI that defines a standard for dependency injection similar to Spring. In a Spring application, the two annotations works the same way as Spring has decided to support some JSR-299 annotations in addition to their own.

@Inject can be injected the reference to the implementation of the Provider interface, which allows injecting the deferred references.
