org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'dataSource' defined in class path resource

回答: 出现这个异常的原因是找不到对应的bean。可能的原因包括：对应的bean没有添加注解、对应的bean添加注解错误、选择错误的自动注入方法等。\[2\]解决方法是确保对应的bean添加了正确的注解，比如在写接口实现类时要加上@Service注解，同时在service层导入dao包下的资源时要加上@Resource注解。\[3\]另外，还可以尝试在启动类上添加注解@EnableAutoConfiguration(exclude = {DataSourceAutoConfiguration.class})来排除DataSource的自动配置。\[1\]
