问题 I would like to use @Repository spring annotation to avoid adding bean in context.xml.

Autowiring Spring superclass

问题 Why does Spring automatically choose the superclass types during autowiring? For instance, if I have @Component public class Foo {} @Component public class Bar extends Foo {} and someone autowires @Autowired private Foo foo; How come Spring always chooses the supertype Foo ? Shouldn't this be an " ambiguous " mapping (and cause Spring to throw an error)? Don't you technically have two Foo candidates? (e.g., Bar gets automatically picked when @Component is removed from Foo...) 回答1: That might

In last Spring auto-wiring in XML example, it will autowired the matched property of any bean in current Spring container. In most cases, you may need autowired property in a particular bean only. In Spring, you can use @Autowired annotation to auto wire bean on the setter method, constructor or a field. Moreover, it can autowired property in a particular bean. Note The @Autowired annotation is auto wire the bean by matching data type. See following full example to demonstrate the use of @Autowired . 1. Beans A customer bean, and declared in bean configuration file. Later, you will use “

To Autowire a class you need to specify it as a bean either by using annotations (@Controller, @Service, @Repository, @Component) or by declaring

Make object spring managed

由 心不动则不痛 提交于 2019-12-06 12:11:23
How can I get an already existing object spring managed? I would like to hook it up to Springs AoP capabilities using aspectj . I know this to be a challenge since Spring AoP uses dynamic proxies which probably are created along with the object. Why do I need this? I have a third-party class which takes a constructor argument which is only known in runtime , hence it seems I cannot add it to my applicationContext or use springs FactoryBean interface for construction. Is there any other way? I've already tried the following without great success: Obj obj = new ThirdPartyObj("runtime constructor
