springboot 静态类中调用bean

1.新建SpringContext类

@Component
@Lazy(false)
public class SpringContext implements ApplicationContextAware {
    private static ApplicationContext applicationContext;

    @Override
    public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
        this.applicationContext = applicationContext;
    }

    private static ApplicationContext getApplicationContext() {
        return applicationContext;
    }

    public static Object getBean(String name) {
        return getApplicationContext().getBean(name);
    }

    public static  T getBean(Class clazz) {
        return getApplicationContext().getBean(clazz);
    }

    public static  T getBean(String name, Class clazz) {
        return getApplicationContext().getBean(name, clazz);
    }
}

2.在静态类中调用方法

 public static void main(String[] args) {
        DemoService demoService = SpringContext.getBean(DemoService.class);
    }
