oracle clob数据保存 oracle数据库里保存clob字段

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); mit(); } catch (RuntimeException re) { throw re; } catch (SQLException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } }
