Java 使用spring-hibernate将blob保存到DB中

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*/
    }

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();
    }
}

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

我正在尝试将excel文件保存为Blob。使用POI库创建excel文件后，已按如下方式创建并传递输入文件InputStream对象：

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

我的hibernate-config.xml更新为会话获取映射的实体&spring-config.xml如下所示：

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();
    }
}

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

尝试使用支持JDBC 4的dbcp版本1.4。

您使用的是哪个版本的dbcp。请共享您的maven文件HI，请查找我的pom.xml文件的片段……正如所见，它是1.2.2版本commons dbcp commons dbcp 1.2.2 commons pool commons pool com.thoughtworks.xstream xstream 1.4.3@ParulChauhan。我已根据您的评论为您的问题添加了代码。今后，请对原始帖子进行更改/编辑，而不是使用评论，以提高可读性。谢谢。我会记住的。谢谢你的帮助。切换到dbcp版本1.4纠正了abstractedbinarystream问题。然而，当更新maven依赖项时，EclipseIDE给了我一段艰难的时间
