implementation types via default constructor * BeanFactory supports ObjectFactory as a dependency type for @Autowired and @Value * BeanFactory supports JSR-330 Provider interface as a dependency type for @Inject to primary bean in parent factory * protected @Autowired method can be overridden with non-annotated method to suppress injection * private @Autowired methods with same signature will be called individually * @Scope and @Transactional are now supported as meta-annotations on custom annotations * @Autowired uses field/parameter name as fallback qualifier value * qualifier annotations can be used at method

setter methods for properties in a domain entity. • Spring’s support for annotations (such as @Autowired, @Inject, and @Resource), that provide dependency injection for private or protected fields, setter these annotations are not specific to tests and can be used anywhere in the Spring Framework. • @Autowired • @Qualifier • @Value • @Resource (javax.annotation) if JSR-250 is present • @ManagedBean (javax type-level annotation that is used to configure how the parameters of a test class constructor are autowired from components in the test's ApplicationContext. If @TestConstructor is not present or meta-present

Fine-tuning |byName|Autowiring by property name. Spring looks for a bean with the same name as the property that needs to be autowired. For example, if a bean definition is set to autowire by name and it contains a master property for a bean definition named master and uses it to set the property.| |byType|Lets a property be autowired if exactly one bean of the property type exists in the container. If more than one exists, a fatal
