oracle中clob转string。

Object ob = dataList.get(i)[j];
String str = null;
if(ob instanceof SerializableClob){
SerializableClob sc = (SerializableClob)ob;
char[] buffer = null;
try {
//根据CLOB长度创建字符数组
buffer = new char[(int)sc.length()];
//获取CLOB的字符流Reader,并将内容读入到字符数组中
sc.getCharacterStream().read(buffer);
} catch (Exception e) {
e.printStackTrace();
}
//转换为字符串
str = String.valueOf(buffer);
}
