What is Autowired?

Autowiring function of spring structure enables you to inject the object dependence implicitly. It internally utilizes setter or constructor injection. Autowiring can’t be used to inject primitive and string values. It works with reference just.

What is difference in between autowired and inject?

The Autowired annotation is used for auto-wiring in the Spring framework. The Inject annotation also serves the exact same function, but the main distinction between them is that Inject is a standard annotation for reliance injection and Autowired is spring specific.

What is use of resource in spring?

The Resource annotation in spring performs the autowiring functionality. This annotation takes an optional name argument. In case no name quality is defined with this annotation, the default name is translated from the field-name or the setter technique (i.e. the bean residential or commercial property name).

Why component is used in Spring?

Element is an annotation that allows Spring to instantly discover our custom-made beans. Simply put, without needing to write any explicit code, Spring will: Scan our application for classes annotated with Component. Instantiate them and inject any defined dependences into them.

What is the difference between bean and Autowired?

What is spring bean life cycle?

Bean life process is handled by the spring container. When we run the program then, first off, the spring container gets going.
