如果找不到实现bean，则自动装配默认实现

Question

I have an interface with 2 default methods. If the implementation is not found, I wish autowire a proxy bean with these 2 default methods. Is this possible in spring?

Answer 1

You need to define bean in some configuration

@Bean
@ConditionalOnMissingBean
public Foo foo(){
    return new Foo() {};
}

where Foo is your interface.
