public void addStatements(StatementsBean statementsBean) {

try {

Session session = this.getSession();

Transaction tran=session.beginTransaction();

statementsBean.setStatementsContent(Hibernate.createClob(" "));//注意,这里的参数是个空格,先新增一个空的Clob进去

session.save(statementsBean);

session.flush();//强制执行

session.refresh(statementsBean,LockMode.UPGRADE);

SerializableClob sc=(SerializableClob)statementsBean.getStatementsContent();//kybasicInfo.getInfoContent()是Clob类型的

Clob wrapclob=sc.getWrappedClob();//这里的Clob是java.sql.Clob

CLOB clob=(CLOB)wrapclob;//这里的CLOB是oracle.sql.CLOB

Writer writer=clob.getCharacterOutputStream();

writer.write(statementsBean.getContentToString());//kybasicInfo.getInfoContentToString()是String类型的,在action里就是传这个进来,然后再通过文件流形式写成CLOB字段中

writer.close();

session.save(statementsBean);

tran.commit();

} catch (RuntimeException re) {

throw re;

} catch (SQLException e) {

e.printStackTrace();

} catch (IOException e) {

e.printStackTrace();

}

}
