我正在努力实现这一目标。我提到了这个link，但对我没有用。这是我的实体类：
@Entity
@Table(name = "DICTIONARY")
public class Dictionary{
public Dictionary() {}
@Id
@GeneratedValue
@Column(name = "DICTIONARY_ID")
private BigDecimal dictId;
@Column(name = "DICTIONARY_DESCRIPTION")
private String description;
@Lob
@Column(name = "DICTIONARY_BIGTEXT_DESCRIPTION") //CLOB column in Oracle
private String bigTextDescription;
//Getters and Setters...
}
这是我的hibernate.cfg.xml：
<hibernate-configuration>
<session-factory>
<property name="hibernate.dialect">org.hibernate.dialect.Oracle10gDialect</property>
<property name="connection.driver_class">oracle.jdbc.OracleDriver</property>
<property name="connection.url">........</property>
<property name="connection.username">.....</property>
<property name="connection.password">.....</property>
<property name="connection.pool_size">10</property>
<property name="connection.autocommit">false</property>
<property name="cache.provider_class">org.hibernate.cache.HashtableCacheProvider</property>
<property name="transaction.factory_class">org.hibernate.transaction.JDBCTransactionFactory</property>
<property name="current_session_context_class">thread</property>
<property name="hibernate.show_sql">true</property>
<property name="show_sql">true</property>
<property name="format_sql">false</property>
<property name="hibernate.jdbc.use_get_generated_keys">true</property>
<property name="hibernate.default_schema">MYDB</property>
<mapping class="com.model.to.Dictionary"/>
</session-factory>
</hibernate-configuration>

我正在使用Hibernate版本4.3.11.Final和ojdbc6 11.2.0.4.jar。请建议我是否遗漏了更多。 提前谢谢！
编辑：我只在Tomcat服务器中遇到此问题。当我在Glassfish服务器上测试时，代码运行罚款。
答案 0 :(得分：2)
现在有点晚了，但我解决了这个问题所以现在发布答案。 我刚刚添加了以下依赖项，它起作用了：
<dependency>
<groupId>org.apache.commons</groupId>
<artifactId>commons-dbcp2</artifactId>
<version>2.0</version>
</dependency>
答案 1 :(得分：1)
尝试使用id
@GeneratedValue(strategy = GenerationType.AUTO)
并使用
@Lob(type = LobType.BLOB)
private String bigTextDescription;
并确保您有兼容的版本
此异常有各种解决方法。这个例外可能 由于与Tomcat服务器一起使用的版本而发生 mysql-connector-java版本以及dpcp实现 （commons.dbcp或tomcat-dbcp）是使用的，当然是版本。
根据聊天中的讨论OA @Shahe正在使用Tomcat 7 mysql-connector-java版本5.1.35是最新版但@Shahe是 使用commons.dpcp和版本1.2.2这是问题所在。
因此将commons-dpcp的版本更新为1.4或更新将解决 这个问题。
