java - Spring Boot 找不到 PersistentEntity

Question

我的仓库

 @Repository
 public interface TasksRepository extends LcR2dbcRepository<Task,Integer> {

   default Flux<Task> findAllTasks(){
        return   SelectQuery.from(Task.class,"root") //Ic spring data r2dbc query
                    .join("root","due","mydue")
                 .execute(getLcClient()).doOnError(System.out::println);
          }
     }

任务模型

 @Getter
 @Setter
 @Builder
 @AllArgsConstructor
 @NoArgsConstructor
 @Table
 public class Task  {

    @Id
    @GeneratedValue
    @Column
    private Integer id;
    @Column
    private Integer comment_count;
    @Column
    private Boolean completed;
    @Column
    private String  content;
    @Column
    private String  url;
    @Column
    private Integer orderdata;
    @Column
    private Integer priority;

    @ForeignKey // this is Ic spring data r2dbc library anotation
    private Integer due;


 }

应届课程

 @Getter
 @Setter
 @NoArgsConstructor
 @AllArgsConstructor
 @Builder
 @Table
 public class Due  {

   @Id
   @GeneratedValue
   @Column
   private Integer id;
   @Column
   private Date my_data;
   @Column
   private Boolean recurring;
   @Column
   private String my_string;

 }

你好，我正在使用 r2dbc 编写一个项目，我在那里使用了这个库https://github.com/lecousin/lc-spring-data-r2dbc#lc-spring-data-r2dbc，但是当我使用它时它给了我一个错误说没有持久性整数类型。问题是什么 ？？？
