jdbc 读取oracle long raw 字段，里面存的是文本

String sql = "select condition from tbl t where t.a = ? and t.b = ?";
PreparedStatement statement = hebSgConn.prepareStatement(sql);
statement.setString(1, "20170305");
statement.setInt(2, 146897);
ResultSet resultSet = statement.executeQuery();
if (resultSet.next()) {
InputStream inputStream = resultSet.getBinaryStream("condition");
ByteArrayOutputStream infoStream = new ByteArrayOutputStream();
int len = 0;
byte[] bytes = new byte[1024];
try {
while ((len = inputStream.read(bytes)) != -1) {
// 将bcache中读取的input数据写入infoStream
infoStream.write(bytes, 0, len);
}
} catch (IOException e1) {
throw new Exception("输入流读取异常");
} finally {
try {
inputStream.close(); // 输入流关闭
} catch (IOException e) {
throw new Exception("输入流关闭异常");
}
}
try {
String result = infoStream.toString(DEFAULT_ENCODING);
System.out.println(result);
} catch (UnsupportedEncodingException e) {
throw new Exception("输出异常");
}
}
