在Java1.6中，Base64编码/解码不能使用特殊字符

import java.util.Base64;

public class Base64Example {
    public static void main(String[] args) {
        String originalData = "Hello, World!";
        
        // 编码
        String encodedData = Base64.getEncoder().encodeToString(originalData.getBytes());
        System.out.println("Encoded data: " + encodedData);
        
        // 解码
        byte[] decodedData = Base64.getDecoder().decode(encodedData);
        String decodedString = new String(decodedData);
        System.out.println("Decoded data: " + decodedString);
    }
}

import org.apache.commons.codec.binary.Base64;

public class Base64Example {
    public static void main(String[] args) {
        String originalData = "Hello, World!";
        
        // 编码
        byte[] encodedData = Base64.encodeBase64(originalData.getBytes());
        String encodedString = new String(encodedData);
        System.out.println("Encoded data: " + encodedString);
        
        // 解码
        byte[] decodedData = Base64.decodeBase64(encodedData);
        String decodedString = new String(decodedData);
        System.out.println("Decoded data: " + decodedString);
    }
}
