我希望能够自动连接单例bean(foo
)
@Component
public class FooUser {
@Autowire Foo foo;
}
由另一个单例方法(FooFactory.createFoo
)创建
@Service
public class FooFactory {
public Foo createFoo() {...}
}
使用xml就是factory-method
。我该如何使用注释?
尝试使用Java @Configuration:
@Configuration
public class Config {
@Bean
public FooUser fooUser() {
return new FooUser(foo());
}
@Bean
public FooFactory fooFactory() {
return new FooFactory();
}
@Bean
public Foo foo() {
return fooFactory().createFoo();
}
}
