德code的base64字符串的Java 5 [英] Decode base64 String Java 5

问题描述

有没有，只使用Java 1.5图书馆脱code一个base64字符串一个直接的方式？

Is there a straight forward way to decode a base64 string using ONLY THE JAVA 1.5 LIBRARIES?

我要使用Java 1.5，由于Windows和Mac OS X的跨平台的兼容性问题（仅限Mac 10.5支持Java 1.6，比一切10.5低了Java 1.5的默认）。

I have to use Java 1.5 due to cross platform compatibility issues between Windows and Mac OS X (only Mac 10.5 supports Java 1.6, everything lower than 10.5 has Java 1.5 as default).

对象sun.misc.Base64De codeR存在于Java 6中，而不是在Java 5中。

The object "sun.misc.Base64Decoder" exists in Java 6, but not in Java 5.

推荐答案

没有，这是不可能的，仅仅基于使用JDK 5.0。

No, it's not possible based on just using JDK 5.0.

您将需要推出自己的实现（这并不难）或preferably使用开源实现之一。有很多，包括共享codeC提供Base64编码的http://commons.apache.org/$c$cc/api-release/org/apache/commons/$c$cc/binary/Base64.html

You'll need to roll your own implementation (it isn't that hard) or preferably use one of the open source implementations. There are lots including Commons Codec which provides Base64 http://commons.apache.org/codec/api-release/org/apache/commons/codec/binary/Base64.html

的JavaMail还提供Base64编码/通过MimeUtility解码也没有引用的可打印编码等...

JavaMail also provides Base64 encoding/decoding via MimeUtility which also does quoted printable encoding etc...
