springboot结合jpa使用MySQL无法解析Driver怎么回事？

Question

一直报错显示无法加载Driverorg.springframework.beans.factory.BeanCreationException: Error creating bean with name 'transactionManager' defined in file [F:\apache-tomcat-7.0.29\webapps\seckill\WEB-INF\classes\spring\spring-service.xml]: Cannot resolve reference to bean 'dataSource' while setting bean property 'dataSource'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'dataSource' is defined

Answer 1

Springboot不是自带DataSource吗，就不需要自己设置了啊

Answer 2

如图片所示，不是IDE问题，就是pom中没声明mysql的jar

Answer 3

你这个错误是没有在XML文件中正确声明出datasource的bean
