=
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"
);
}
}
基本上是流操作;
