Java 在部署spring项目时，我遇到依赖项注入错误

pom.xml

为类添加注释

Spring不是用来寻找公共服务依赖性的。请在CommonUtilServiceImpl上添加@Service注释

@Service
public class CommonUtilServiceImpl implements CommonUtilService {

你的问题是什么？你的密码在哪里？现在还不清楚你在问什么。你展示了pom文件。但是异常来自Java[Spring]：NoSuchMethodError。

NoSuchBeanDefinitionException

，自动布线出错！如何解决这个问题
