What is difference between @primary and @Qualifier?

Question

Accepted Answer

Primary is used to define a primary bean when multiple beans of the same type are present, while Qualifier is used to specify which bean to autowire when multiple beans of the same type are present.

Primary annotation is used to give a higher preference to a bean when multiple beans of the same type are present in the Spring application context.
Qualifier annotation is used to specify which bean to autowire when multiple beans of the same type are present. It helps in resolving the ambiguity.
Primary is used at the class level, while Qualifier is used at the field or parameter level.
Example: @Primary annotation can be used with a primary bean definition, while @Qualifier("beanName") can be used to specify the bean to be autowired by name.
