Java Clob 类型转 String

        Java 中，使用oracle数据库存储Clob类型，需要转换成String类型

        

    /**
     * Clob类型 转String
     */
    public String clobToString(Clob clob) throws SQLException, IOException {
        String str = "";
        Reader reader = clob.getCharacterStream();
        BufferedReader br = new BufferedReader(reader);
        String readLine = br.readLine();
        StringBuilder sb = new StringBuilder();
        while (readLine != null) {
            sb.append(readLine);
            readLine = br.readLine();
        }
        str = sb.toString();
        br.close();
        reader.close();
        return str;
    }
