【问题描述】：
我正在开发 this tutorial，但必须升级到 hibernate 4 作为一些更改的一部分，以使其与更现代的工具一起使用。
当我尝试在 hibernate 4 和 spring 中对 MySQL 数据库执行 blob 操作时，有人可以告诉我如何解决引发的错误吗？
目前，以下代码行正在触发错误：
session.save(document); //line 23
这是代码行所在的方法：
@Transactional
public void save(Document document) {
Session session = sessionFactory.getCurrentSession();
session.save(document); //line 23
}
这是包含该方法的类：
@Repository
public class DocumentDAO {
@Autowired
private SessionFactory sessionFactory;
@Transactional
public void save(Document document) {
Session session = sessionFactory.getCurrentSession();
session.save(document); //line 23
}
@Transactional
public List<Document> list() {
Session session = sessionFactory.getCurrentSession();
List<Document> documents = null;
try {documents = (List<Document>)session.createQuery("from Document").list();}
catch (HibernateException e) {e.printStackTrace();}
return documents;
}
@Transactional
public Document get(Integer id) {
Session session = sessionFactory.getCurrentSession();
return (Document)session.get(Document.class, id);
}
@Transactional
public void remove(Integer id) {
Session session = sessionFactory.getCurrentSession();
Document document = (Document)session.get(Document.class, id);
session.delete(document);
}
}
这里是被抛出的异常：
HTTP Status 500 - Handler processing failed; nested exception is java.lang.AbstractMethodError: org.apache.commons.dbcp.DelegatingPreparedStatement.setBinaryStream(ILjava/io/InputStream;J)V

这里是hibernate.cfg.xml：
<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
<session-factory>
<mapping class="net.viralpatel.docmanager.model.Document" />
</session-factory>
</hibernate-configuration>
这里是 Document 类：
@Entity
@Table(name="documents")
public class Document {
@Id
@GeneratedValue
@Column(name="id")
private Integer id;
@Column(name="name")
private String name;
@Column(name="description")
private String description;
@Column(name="filename")
private String filename;
@Column(name="content")
@Lob
private Blob content;
@Column(name="content_type")
private String contentType;
@Column(name="created")
private Date created;
//Getter and Setter methods
public Blob getContent(){return content;}
public String getContentType(){return contentType;}
public String getDescription(){return description;}
public String getFileName(){return filename;}
public String getName(){return name;}
public void setContent(Blob ct){content=ct;}
public void setContentType(String ctype){contentType=ctype;}
public void setDescription(String desc){description=desc;}
public void setFileName(String fn){filename=fn;}
public void setName(String nm){name=nm;}
}
jdbc.properties 是：
jdbc.driverClassName= com.mysql.jdbc.Driver
jdbc.dialect=org.hibernate.dialect.MySQLDialect
jdbc.databaseurl=jdbc:mysql://localhost:3306/docbd
jdbc.username=user
jdbc.password=pwd

【问题讨论】：
-
你能展示你的实体和你的数据源/连接和休眠配置吗？
-
我的意思是你的 Document 类
-
另外，您使用的是哪个版本的 apache 数据库连接池，您确定这是完整的堆栈吗？
-
我的意思是你的 hibernate.cfg.xml 或者你配置数据库连接细节的地方。
-
@Taylor 我添加了一些东西。他们是你要找的吗？我还有一个 jdbc.properties 文件，它为 5 个 jdbc 属性设置值，并从我的应用程序上下文 xml 中调用。你看到我的 hibernate.cfg.xml 引用了 hibernate 3 吗？那是错误吗？如果是这样，我该如何解决？
