java base64 编码 解码

public static void main(String[] args) throws Exception {

		String parm = "Title=不要这样额&Content=好好好好好";

		// BASE64Decoder
		String paramBase64 = new BASE64Encoder().encode(parm.getBytes("utf-8"));
		System.out.println("转base64：" + paramBase64);

		BASE64Decoder decoder = new BASE64Decoder();
		byte[] decoderStr = decoder.decodeBuffer(paramBase64);

		System.out.println("转码后：" + new String(decoderStr));

加号问题

titleBase64.replaceAll("[+]", "%2B")

sr = sr.replaceAll(" ", "").replaceAll(" ", "");

base64查询处理

String titleReturn = "";
		if (message.getTitle() != null) {
			titleReturn = message.getTitle();
			String baseTitle = new BASE64Encoder().encode(message.getTitle()
					.getBytes());
			if (baseTitle.contains("=")) {
				int index = baseTitle.indexOf("=");
				baseTitle = baseTitle.substring(0, index - 1);
			}

			message.setTitle(baseTitle);
		}
