Spring boot随时获取ApplicationContex

1. @Service
2. public class SpringManager implements ApplicationListener<ContextRefreshedEvent> {
3. private static ApplicationContext applicationContext = null;
4. @Override
5. public void onApplicationEvent(ContextRefreshedEvent event) {
6. if(applicationContext == null){
7. applicationContext = event.getApplicationContext();
8. }
9. }
10. /*ApplicationContext context= ContextLoader.getCurrentWebApplicationContext();//尝试下这个方法*/
11. public static ApplicationContext getApplicationContext() {
12. return applicationContext;
13. }
14. }

@Service
public class SpringManager implements ApplicationListener<ContextRefreshedEvent> {
    private static ApplicationContext applicationContext = null;
    @Override
    public void onApplicationEvent(ContextRefreshedEvent event) {
        if(applicationContext == null){
            applicationContext = event.getApplicationContext();
        }
    }
    /*ApplicationContext context= ContextLoader.getCurrentWebApplicationContext();//尝试下这个方法*/
    public static ApplicationContext getApplicationContext() {
        return applicationContext;
    }
}

1. 或者
2. @Service
3. public class SpringTool implements ApplicationContextAware {
4. private static ApplicationContext context = null;
5. @Override
6. public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
7. context = applicationContext;
8. }
9. public static ApplicationContext getApplicationContext() {
10. return context;
11. }
12. }

或者
@Service
public class SpringTool implements ApplicationContextAware {
    private static ApplicationContext context = null;
	@Override
	public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
		context = applicationContext;
	}
    public static ApplicationContext getApplicationContext() {
        return context;
    }

}

1. 或者直接  
2.     @Autowired  
3.     ApplicationContext context;  

或者直接

@Autowired

ApplicationContext context;
