使用Spring数据使用Spring Boot引导Apache点燃

Question

I am trying to do caching with  apache ignite 2.7.5  in spring boot 2. Here application starts and ignite node is up but the caching is not working (i dont have any errors in console).

---

Here is my config file
@Bean
public Ignite igniteInstance() {

        IgniteConfiguration  cfg = new IgniteConfiguration();

        cfg.setIgniteInstanceName("springDataNode");
        cfg.setPeerClassLoadingEnabled(true);

        CacheConfiguration    studcfg = new CacheConfiguration("studentCache");
        CacheConfiguration    coursecfg = new CacheConfiguration("courseCache");

        studcfg.setIndexedTypes(Long.class,Student.class);
        coursecfg.setIndexedTypes(Long.class,Course.class);

        cfg.setCacheConfiguration(new CacheConfiguration[] {studcfg,coursecfg});
        return Ignition.start(cfg);     
    }
*************************************************************************
here is my repositories
@RepositoryConfig(cacheName = "studentCache")
public interface StudentRepository extends IgniteRepository<Student,Long> {

    List<Student> getStudentByName(String name);
    Student getStudentById (Long id);
}
@RepositoryConfig(cacheName = "courseCache")
public interface CourseRepository extends IgniteRepository<Course, Long> {


    List<Course> getAllCourseByName (String name);

    @Query("SELECT id FROM Breed WHERE id = ?")
    List<Long> getById (Long id, Pageable pageable);

}

here is the caching part
public class CacheApp {

    private static   AnnotationConfigApplicationContext ctx;

    @Autowired
    private static   StudentRepository studentRepository;

    @Autowired
    private static   CourseRepository courseRepository;


    public static void main(String[] args)
        {
            System.out.println( "Spring Data Example!" );
            ctx = new AnnotationConfigApplicationContext();
            ctx.register(SpringConfig.class);
            ctx.refresh();

            studentRepository= ctx.getBean(StudentRepository.class);
            courseRepository= ctx.getBean(CourseRepository.class);

            Student stud1= new Student();
            stud1.setId(111);
            stud1.setName("ram");
            studentRepository.save(stud1);

            List<Student> getAllBreeds = studentRepository.getStudentByName("ram");

            for(Student student : getAllBreeds){
                System.out.println("student:" + student);
            }

            Course course1= new Course();
            course1.setId(1);
            course1.setName("maths");
            courseRepository.save(course1);

            List<Course> courses = courseRepository.getAllCourseByName("maths");
            for(Course cor : courses){
                System.out.println("courses:"+ cor);
            }
      }
}

here is my console log

您需要使用@EnableIgniteRepositories才能在Spring Data中启用Apache Ignite支持的存储库。
