休眠：映射字符串屬性CLOB列

我努力實現這一目標。我提到這個link，但沒有爲我工作。這是我的實體類：休眠：映射字符串屬性CLOB列

@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... 
}

這裏是我的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>

下面是我的pom.xml：

我正在使用Hibern吃了版本4.3.11.Final和ojdbc6 11.2.0.4.jar。請建議我是否缺少更多。 在此先感謝！

編輯：我只在Tomcat服務器面臨這個問題。當我在Glassfish服務器上測試它時，代碼會運行罰款。

末現在

有一點，但我解決了這個問題，所以張貼現在答案。 我剛剛添加了以下依賴項，它工作：

 <dependency> 
      <groupId>org.apache.commons</groupId> 
      <artifactId>commons-dbcp2</artifactId> 
      <version>2.0</version> 
     </dependency>

嘗試使用ID

@GeneratedValue(strategy = GenerationType.AUTO)

，並使用

@Lob(type = LobType.BLOB) 
private String bigTextDescription;

，並確保您有兼容版本

這個例外有不同的路徑來解決這個問題。這種異常可能 的發生是由於版本到Tomcat服務器 MySQL的連接器的Java版本，並且還一起使用DPCP實施 （commons.dbcp或Tomcat-DBCP）使用哪種和它的過程的版本。

根據聊天OA @Shahe討論與 使用mysql-connector-java版5.1.35這是最新的一個沿着使用Tomcat 7，但@Shahe使用commons.dpcp與1.2.2版本，這是問題是 。

所以更新公地DPCP的版本1.4或最新將會解決 問題。

謝謝您的回覆。我正在使用Tomcat 7.0。我在Eclipse中檢查了我的Maven依賴項，但是找不到任何commons-dpcp jar文件。我可以檢查版本。 –

發佈您的build.gradle或pom.xml –

編輯我的問題。也是type = LobType.BLOB對@Lob有效嗎？ –
