Spring-JPA 存储库自定义行为

Question

我已按照 Spring-Data-JPA 参考将自定义行为添加到我的存储库之一。但是我在运行时收到“找不到类型的属性”错误。 不确定我在代码中哪里做错了，或者在配置中遗漏了任何东西。 谢谢你的帮助。

自定义行为：

public interface JobStatusRepositoryCustom {
    JobStatusEntity retrieveJobStatus(int projectId, int jobId, int executionId);
}

public class JobStatusRepositoryImpl implements JobStatusRepositoryCustom {
    @PersistenceContext
    private EntityManager entityManager;

    @Override
    public JobStatusEntity retrieveJobStatus(int projectId, int jobId, int executionId) {
        String query = "SELECT e.* FROM JobStatusEntity e WHERE e.projectId=? AND e.jobId=? AND e.executionId=?";
        return (JobStatusEntity)entityManager.createQuery(query)
                .setParameter(1, projectId)
                .setParameter(2,  jobId)
                .setParameter(3, executionId)
                .getSingleResult();
    }
}

主存储库接口：

public interface JobStatusRespository extends JpaRepository<JobStatusEntity, Integer>, JobStatusRepositoryCustom {
}

配置：

@EnableJpaRepositories( {"com.alu.mdm.*.repository", "com.alu.mdm.*.dao" })

上面的运行时异常：

我想你只是打错了：
