Java 使用Spring JPA自定义查询的IllegaArgument异常？

我正试图用Spring JPA实现一个自定义查询，但得到的却是IllegalArgumentException

org.hibernate.hql.internal.ast.QuerySyntaxException:MY_表未映射

import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Table;
import java.util.Date;


    @Entity
    @Table(name = "MY_TABLE")
    public class MyTable {

        @Id
        @GeneratedValue(strategy= GenerationType.AUTO)
        private Long id;
        private String corrected;
        private String custom;



import org.springframework.data.jpa.repository.Query;
import org.springframework.data.repository.CrudRepository;
import org.springframework.data.repository.query.Param;

public interface MyTableRepository extends CrudRepository<MyTable, Long> {


    @Query(value = "select i from MY_TABLE i where corrected = 'Y' AND custom = :custom")
    public Iterable<MyTable> findCustom(@Param("custom") String custom);


}

import javax.persistence.Entity；
导入javax.persistence.GeneratedValue；
导入javax.persistence.GenerationType；
导入javax.persistence.Id；
导入javax.persistence.Table；
导入java.util.Date；
@实体
@表（name=“MY_表”）
公共类MyTable{
@身份证
@GeneratedValue（策略=GenerationType.AUTO）
私人长id；
私人字符串已更正；
私人字符串自定义；
导入org.springframework.data.jpa.repository.Query；
导入org.springframework.data.repository.crudepository；
导入org.springframework.data.repository.query.Param；
公共接口MyTableRepository扩展了Crudepository{
@查询（value=“从我的_表i中选择i，其中corrected='Y'和custom=:custom”）
public Iterable findCustom（@Param（“custom”）字符串custom）；
}

--

原因：java.lang.IllegalArgumentException:方法公共抽象java.lang.Iterable com.me.MyRepo.findCustom（java.lang.String）的查询验证失败！
