oracle中clob轉string。

Object ob = dataList.get(i)[j];
String str = null;
if(ob instanceof SerializableClob){
SerializableClob sc = (SerializableClob)ob;
char[] buffer = null;
try {
//根據CLOB長度創建字符數組
buffer = new char[(int)sc.length()];
//獲取CLOB的字符流Reader,並將內容讀入到字符數組中
sc.getCharacterStream().read(buffer);
} catch (Exception e) {
e.printStackTrace();
}
//轉換為字符串
str = String.valueOf(buffer);
}
