使用spring - hibernate将blob保存到DB中

时间：2016-05-25 05:44:30

标签： java spring hibernate session blob

我的实体类是：

@Entity
@Table (name = "rs_production_dump")
public class ProdDumpBLOB implements Serializable{
    /**
     * the serial version id.
     */
    private static final long serialVersionUID = -3395282616292841663L;

    @Column(name = "report_name")
    protected String reportName;

    @Column(name = "report")
    protected Blob report;

    @Column(name = "mime_type")
    protected String mimeType ;
    /* getters & setters*/
    }

用于保存BLOB的DAO层方法如下：

public void saveProdDumpBLOB(ProdDumpBLOB produmpblob, FileInputStream fis, long filelength){

    try {

        LoggerUtil.infoApplicationLog(".... inside saveProdDumpBLOB ...." + sessionFactory);

        Session session = this.sessionFactory.getCurrentSession();

        Blob blob1 = Hibernate.getLobCreator(session).createBlob(fis,filelength);

        produmpblob.setReport(blob1);

        session.save(produmpblob);

        LoggerUtil.infoApplicationLog(".... exiting saveProdDumpBLOB ....");
    }

    catch (Exception e) {
        LoggerUtil.errorApplicationLog("Error : ProdDumpBLOBDaoImpl:saveProdDumpBLOB. #Error Message: " + e.getMessage(), e);
        e.printStackTrace();
    }
}

我试图将excel文件保存为Blob。在使用POI库创建excel文件后，已创建并传递输入fileinputstream对象：

File xlsfile = new File(fileName);
FileInputStream fis = new FileInputStream(xlsfile);

我的hibernate-config.xml使用为会话提取映射的实体进行更新＆amp; spring-config.xml如下：

<bean id="prodDumpBlobDaoImpl" class="com.comp.ecmrs.dao.impl.ProdDumpBLOBDaoImpl">
        <property name="sessionFactory" ref="sessionFactory" />
    </bean>

我认为这应该可以解决问题，但我仍然在我的日志中收到此错误：
