本篇文章小编给大家分享一下SpringBoot中的main方法注入service代码示例,文章代码介绍的很详细,小编觉得挺不错的,现在分享给大家供大家参考,有需要的小伙伴们可以来看看。
在springboot中使用main方法常规无法注入service,因为以后也可能会有这种情况,所以采取工具类的方式进行,该工具类为固定写法,直接复制就行
@Component public class SpringContextUtil implements ApplicationContextAware { private static ApplicationContext applicationContext = null; @Override public void setApplicationContext(ApplicationContext applicationContext) throws BeansException { if (SpringContextUtil.applicationContext == null) { SpringContextUtil.applicationContext = applicationContext; } } public static ApplicationContext getApplicationContext() { return applicationContext; } public static Object getBean(String name) { return getApplicationContext().getBean(name); } public staticT getBean(Class clazz) { return getApplicationContext().getBean(clazz); } public static T getBean(String name, Class clazz) { return getApplicationContext().getBean(name, clazz); } }
然后在需要注入的地方,创建静态service
private static Service service;
然后在需要使用的main方法中:
public static void main(String[] args) { SpringApplication.run(**Application.class,args); ApplicationContext applicationContext = SpringContextUtil.getApplicationContext(); service = applicationContext.getBean(**Service.class); }
