Spring autowiring using @Resource and @Inject annotation example

By Atul Rai | Last Updated: September 2, 2018 Previous       Next

In the previous tutorial Spring @Autowired annotation example, we have performed the autowiring using @Autowired annotation on field, setter method, and constructor. Now in this tutorial, we are going to discuss autowiring through the @Resource and @Inject annotations. These annotations have the same properties as @Autowired. Check these key points.

Note: Autowiring functionality allows you to inject only secondary type’s value, it is not applicable for primitive type’s value. Primitive types value must be inject manually.

Let’s check the snippet of code of these annotations. We are not going to write whole code here because we have a similar article for the same check it.

@Resource

@Resource annotation available in javax.annotation package.

package org.websparrow;

import javax.annotation.Resource;

public class ResourceBean {

	@Resource
	private State state;

	public void display() {
		System.out.println("State name is: " + state.getStateName());
	}
}

@Inject

@Inject annotation available in javax.inject package.

package org.websparrow;

import javax.inject.Inject;

public class InjectBean {

	@Inject
	private State state;

	public void display() {
		System.out.println("State name is: " + state.getStateName());
	}
}
