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