如何自动连接@bean类

Question

I have following @Configuration class

@Configuration
public class SomeClass {
    @Bean
    public BeanClass get() {
        return new BeanClass()
    }
}

Now I want to autowire BeanClass in some other class

public class SomeClass2 {
    @Autowired
    BeanClass beanCLass
}

Currently beanClass is coming null.
What and how exactly I need to tell spring for this autowiring.

Answer 1

According to Spring documentation

By default, the bean name will be that of the method name

get is your bean name, try with this configuration:

@Configurtion
public class SomeClass {
    @Bean
    public BeanClass beanCLass() {
        return new BeanClass()
    }
}

Bean

@Component
public class SomeClass2 {
    @Autowired
    BeanClass beanCLass
}

Answer 2

Your SomeClass2 must be a spring bean. Annotate SomeClass2 with @Component.
