SpringBoot和Hibernate无法根据提供的条件检索对象列表

Question

尝试使用SpringBoot和Hibernate / JPA从数据库获取对象列表时遇到问题。 在数据库中，我列出了RFI，其中一个字段为open / close / more。 目的是检索所有打开的RFI的完整列表并将其插入视图中。 当我在下面运行代码时，我只有一堆带有空值的控制台输出，而最后一个则有所不同。 您能告诉我我在做什么错吗？

这是我的模型下面的代码：

package com.robi.PlanningRfiTracker.model;

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

    @Entity
    public class Rfi {

        @Id
        @GeneratedValue(strategy = GenerationType.AUTO)
        private Long id;
        private String pprnumber;
        private String title;
        private String site;
        private String rfi;
        private Date datesubmitted;
        private String response;

        }

    }

RfiDao：

package com.robi.PlanningRfiTracker.dao;

import java.util.List;
import org.springframework.data.repository.CrudRepository;
import com.robi.PlanningRfiTracker.model.Rfi;

public interface RfiDao extends CrudRepository<Rfi, List> {
    List<Rfi> findByStatus(String status);
}

RfiService：

        package com.robi.PlanningRfiTracker.service;

    import java.util.List;
    import com.robi.PlanningRfiTracker.model.Rfi;

    public interface RfiService {
        List<Rfi> rfiStatus(String status);
    }

RfiServiceImpl:



 package com.robi.PlanningRfiTracker.service.RfiServiceImpl;

import java.util.List;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import com.robi.PlanningRfiTracker.dao.RfiDao;
import com.robi.PlanningRfiTracker.model.Rfi;
import com.robi.PlanningRfiTracker.service.RfiService;

@Service
public class RfiServiceImpl implements RfiService {

    @Autowired
    private RfiDao rfiDao;

    @Override
    public List<Rfi> rfiStatus(String status) {
        return (List<Rfi>) rfiDao.findByStatus(status);
    }

}

我在上面运行此代码时附上了控制台输出的图片。

谢谢控制台输出

在crud界面上使用它。 变长列表

public interface RfiDao extends CrudRepository<Rfi, Long> {
    List<Rfi> findByStatus(String status);
}
