Furthermore, Address class has two child classes: PermanentAddress and MailingAddress. For example, if we have a Person class and an Address class. What is the Ambiguity Issue while Using we have multiple possible dependencies to inject to a property of the target class and we didn’t specify which dependency needs to be injected, we might see NoUniqueBeanDefinitionException. However, this issue can be handled after applying some additional logic.ģ) It may lower the readability of the code. In other words, we can’t apply it with other property types such as primitive types, String types etc.Ģ) Since autowiring is done automatically, it can create an ambiguity issue when there are two beans of the same type. There are some limitations while we apply autowiring in Spring:ġ) Autowiring in Spring is possible only on reference type/object type properties. What are the limitations of Autowiring in Spring? We can use the annotation at constructor level, field level, setter method level, and normal method level. When a bean is autowired, Spring will automatically resolve its dependencies and create the required objects. This annotation can be used to inject a bean into another bean. In other words, when we want to enable autowiring on a specific property, we can achieve it by using the annotation. When we want to instruct the Spring container to detect and inject dependent beans to the properties of the target bean automatically, we use annotation. Note: Since the autowiring is part of Spring Core Framework, all concepts will also be applicable in Spring Boot. When we apply autowiring, Spring looks for the beans of the required dependency type in the container and automatically injects them into the dependent object. This can save a lot of time and effort, especially in large-scale applications where there are a large number of dependencies between objects.
