java - 无法使用 hibernate spring mvc 更新表

Question

我的实体类如下

package com.ibs.entity;

import java.util.Date;

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Table;
import javax.persistence.Temporal;
import javax.persistence.TemporalType;

import org.hibernate.annotations.GenericGenerator;

@Entity
@Table(name = "InitialMedicalCheckUpG3")
public class InitialMedicalCheckUpEntity {

    private int imcsId;
    private String empId, status, updatedBy, remarks;
    Date updatedOn;

    @Column(name = "IMCS_ID")
    public int getImcsId() {
        return imcsId;
    }

    public void setImcsId(int imcsId) {
        this.imcsId = imcsId;
    }

    @Id
    @Column(name = "EMP_ID")
    @GeneratedValue(generator = "increment", strategy = GenerationType.AUTO)
    @GenericGenerator(name = "increment", strategy = "increment")
    public String getEmpId() {
        return empId;
    }

    public void setEmpId(String empId) {
        this.empId = empId;
    }

    @Column(name = "STATUS")
    public String getStatus() {
        return status;
    }

    public void setStatus(String status) {
        this.status = status;
    }

    @Column(name = "UPDATED_BY")
    public String getUpdatedBy() {
        return updatedBy;
    }

    public void setUpdatedBy(String updatedBy) {
        this.updatedBy = updatedBy;
    }

    @Column(name = "REMARKS")
    public String getRemarks() {
        return remarks;
    }

    public void setRemarks(String remarks) {
        this.remarks = remarks;
    }

    @Temporal(TemporalType.TIMESTAMP)
    @Column(name = "UPDATED_ON", insertable = false)
    public Date getUpdatedOn() {
        return updatedOn;
    }

    public void setUpdatedOn(Date updatedOn) {
        this.updatedOn = updatedOn;
    }

}

数据访问对象 ->

package com.ibs.dao;

import java.util.List;

import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Repository;

import com.ibs.entity.InitialMedicalCheckUpEntity;

@Repository
public class InitialMedicalCheckUpDaoImpl implements InitialMedicalCheckUpDao {

    @Autowired
    SessionFactory sessionFactory;

    @Override
    public List<InitialMedicalCheckUpEntity> getConfirmedList() {
        // TODO Auto-generated method stub
        return null;
    }

    @Override
    public List<InitialMedicalCheckUpEntity> getNonConfirmedList() {
        // TODO Auto-generated method stub
        return null;
    }

    @Override
    public void update(InitialMedicalCheckUpEntity e) {
        // TODO Auto-generated method stub
        System.out.println(e.getStatus());
        sessionFactory.getCurrentSession().update(e);
    }

}

Hibernate 为我的更新语句准备了以下查询 -> hibernate : 更新 InitialMedicalCheckUpG3 设置 IMCS_ID=?、REMARKS=?、STATUS=?、UPDATED_BY=?、UPDATED_ON=?其中 EMP_ID=？

因此该表没有更新。

我使用服务类中的 Dao-> 包 com.ibs.service;

import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;

import com.ibs.dao.InitialMedicalCheckUpDao;
import com.ibs.entity.InitialMedicalCheckUpEntity;

@Service
public class InitialMedicalCheckUpServiceImpl implements
    InitialMedicalCheckUpService {

    @Autowired
    InitialMedicalCheckUpDao dao;

    @Override
    public List<InitialMedicalCheckUpEntity> getConfirmedList() {
        // TODO Auto-generated method stub
        return null;
    }

    @Override
    public List<InitialMedicalCheckUpEntity> getNonConfirmedList() {
        // TODO Auto-generated method stub
        return null;
    }

    @Override
    @Transactional
    public void update(InitialMedicalCheckUpEntity e) {
        // TODO Auto-generated method stub
        dao.update(e);

    }

}

通过hibernate进行的每个操作都需要与一个事务相关联。您需要确保您的更新操作是事务的一部分并且该工作单元已提交。确保您将此操作与事务关联并提交。
