How can I update all spring objects after setting

问题:

How can I refresh previously @Autowired spring objects after dynamic configuration changes?

// Here is my updateConfig method

GenericApplicationContext context = new GenericApplicationContext();
XmlBeanDefinitionReader reader = new XmlBeanDefinitionReader(context);
reader.loadBeanDefinitions(new ClassPathResource("applicationContext.xml"));
context.refresh();

myApplicationContextAware.setApplicationContext(context);

With myApplicationContextAware.applicationContext.getBean(MyClass.class) I can get new instances by new configuration, but all @Autowired objects still contain old values

Is there any solution to refresh spring objects?

You can use AbstractRefreshableApplicationContext for this. It provides methods to reload bean configuration in run time.

If you're using spring boot then you can use @RefreshScope annotation with the spring actuator. Spring actuator endpoint /refresh reloads the beans annotated with @RefreshScope.
