通过在Spring boot中更改属性来切换bean

public interface MyBean {
    void doSomething();
}

@Component
public class MyBeanImpl1 implements MyBean {
    @Override
    public void doSomething() {
        System.out.println("Using MyBeanImpl1");
    }
}

@Component
public class MyBeanImpl2 implements MyBean {
    @Override
    public void doSomething() {
        System.out.println("Using MyBeanImpl2");
    }
}

mybean.impl=impl1

@Configuration
public class MyBeanConfiguration {

    @Value("${mybean.impl}")
    private String myBeanImpl;

    @Autowired
    private MyBeanImpl1 myBeanImpl1;

    @Autowired
    private MyBeanImpl2 myBeanImpl2;

    @Bean
    public MyBean myBean() {
        if ("impl1".equals(myBeanImpl)) {
            return myBeanImpl1;
        } else {
            return myBeanImpl2;
        }
    }
}

@RestController
public class MyController {

    @Autowired
    private MyBean myBean;

    @GetMapping("/do-something")
    public void doSomething() {
        myBean.doSomething();
    }
}
