private Long id;private String name;// getters and setters…}public interface UserRepository extends JpaRepository {}通过以上步骤,你应该能够解决在Spring Boot应用中遇到的’Error creating bean with name ‘dataSource’ defined in class path resource [spring/spring-datasour]’错误。如果问题仍然存在,请...
该bug直译就是无法创建dataSource实例,有很多种情况都会造成。 比如说,你的jdbc.properties文件和spring配置文件applicationContext.xml文件写得不一样。 明显可以看出jdbc.driverClass是灰的,因为和property的name属性写的不是一样的东西。 也有可能是依赖没有导入,比如说没有导入spring - aspect jar包等等……我学习...

找到com.baobaotao.service.UserService实现类型 @Service这个扔到实现类上 2 TestUserService的控制器使用接口声明要注入的变量 @Autowired private UserService userService; 不知道具体怎么错误，你测试下。
