本文介绍了在使用@Resource注解时遇到的NoSuchMethodError错误及其解决方案。错误发生在依赖注入过程中，原因是缺少必要的javax.annotation-api jar包。文中给出了正确的依赖配置。

【1】今天写项目的时候突然碰到了一个错，之前本来是通过@Autowired注解获取对象的，然是后来我改成了@Resource注解就开始报错了

【2】后来上网一查才知道，是少了一个配置的jar包，并且了解到JDK1.8之后就不主动支持@Resource了，必须自己手动倒jar包

<dependency>
            <groupId>javax.annotation</groupId>
            <artifactId>javax.annotation-api</artifactId>
            <version>1.2</version>
        </dependency>
