Hibernate操作clob类型的数据问题

使用hibernate的createSQLQuery进行查询clob类型数据的时候发现问题：
查询出来的数据是一个内存地址，那现在问题怎么解决呢?

	public String findEmail() throws IOException{
		// 获取邮箱
		Session currentSession = this.currentSession();
		String sql = "SELECt VALUE_TEXT FROM table WHERe DICT_CODE = 'EMAIL' ";
		SQLQuery query = currentSession.createSQLQuery(sql);
		Clob clob = (Clob) query.list().get(0);
		Reader inStreamDoc = null;
		String email ="";
		try{
			inStreamDoc = clob.getCharacterStream();
			char[] tempDoc = new char[(int) clob.length()];
			inStreamDoc.read(tempDoc);  
			email = new String(tempDoc);
		}catch(SQLException e){
			System.out.println("***Action clob转换String类型失败" + e);
		}catch(IOException e){
			System.out.println("***Action clob转换String类型失败" + e);
		}finally{
			inStreamDoc.close();
		}
		return email;
	}
