How to get the value from the s3 input stream in java
问题
我正在尝试获取值：
public char getTs() throws IOException {S3ObjectInputStream ts = null;int i;ts = (S3ObjectInputStream) s3Services.getResourceStream(fileURL.toString());while ((i = ts.read()) != -1) {c = (char) i;LOGGER.info("req time {}", c);}return c;}
我得到的值是以位为单位的，如何一次获取整个值？
是否适合使用数组？
我的输出：
req time 0
req time 1
req time -
req time 0
req time 1....等等
预期输出：
req time 01-01-2000 03:10:10
英文:
I am trying to get value here :
public char getTs() throws IOException {S3ObjectInputStream ts = null;int i;ts = (S3ObjectInputStream) s3Services.getResourceStream(fileURL.toString());while ((i = ts.read()) != -1) {c = (char) i;LOGGER.info("req time {} ", c);}return c;}
The value I am getting is in bits, how to get the whole value at once?
Is it suitable to use an array?
My Output :req time 0req time 1req time -req time 0req time 1.... and so on
My expected output is :req time 01-01-2000 03:10:10

你可以将 S3ObjectInputStream 包装在 InputStreamReader 中，然后将 InputStreamReader 包装在 BufferedInputStream 中。这样，你可以逐行读取对象：
var reader = new BufferedReader(new InputStreamReader(ts));var line = reader.readLine();
此外，还可以查看 Apache Commons IO，该库提供了额外方便的流、读取器和工具。
英文:
You could wrap the S3ObjectInputStream within an InputStreamReader and the InputStreamReader within a BufferedInputStream. That way you can read the object line by line:
var reader = new BufferedReader(new InputStreamReader(ts));var line = reader.readLine();
Also check out Apache Commons IO which provide additional convenient streams and readers and utilities.
