以下代码有助于解除clob的固定
链接帮助我，只是添加了一点化妆的代码：d

你可以试试这个代码。它可能并不完美，但对我来说很有用：）我正在使用它将常规clob转换为字符串，因此如果使用getwrappedclob（）展开clob对象，它也应该可以工作

Clob clob = wrappedClob.getWrappedClob();
String result = null;
Long length = clob.length();
char[] char_array = new char[length.intValue()];
Reader characterStream = clob.getCharacterStream();
try {
    int read = characterStream.read(char_array, 0, length.intValue());
    result = new String(char_array);
} catch (IOException e) {
    log.error("Exception during read from CLOB: " + e);
}
