spring boot不能注入JpaRepository接口，提示找不到bean

Question

Field studentRepository in com.example.demo.StudentController required a bean of type 'com.example.demo.StudentRepository' that could not be found. Action: Consider defining a bean of type 'com.example.demo.StudentRepository' in your configuration. @RestController public class StudentController { @Autowired private StudentRepository studentRepository; @GetMapping(value = "/findAll") public List<Student> studentList(){ return studentRepository.findAll(); } } StudentRepository 继承 JpaRepository，应该是个最简单的例子了 一共就一个包，SpringBootApplication和Controller都放在一个包下面，应该不会出现网上的顺序的问题

Answer 1

我自己解决了，jpa的包冲突了。
