Map转Json转Base64

Map<String,String> configMap = new HashMap<String,String>();

System.out.println("JSON.toJSONString(configMap) is " + JSON.toJSONString(configMap)); //第一种 import com.alibaba.fastjson.JSON;
System.out.println("JsonUtils.toJson(configMap) is " + JsonUtils.toJson(configMap)); //第二种 import com.pisgah.common.util.JsonUtils;

try{
     byte byteXl[] = JSON.toJSONString(configMap).getBytes("UTF-8"); //字符串转化为一个字节数组byte[]
  Base64 encoder = new Base64();
  String encodedStr = encoder.encodeToString(byteXl); //第一种 转Base64
  System.out.println("encodedStr is " + encodedStr);
  String base64EncStr= new String (Base64.encodeBase64(byteXl),"UTF-8"); //第二种 转Base64
  System.out.println("base64EncStr is " + base64EncStr);
 }catch(Exception e){
 e.printStackTrace();
 }
例：

public static void main(String[] args) {

        Map<String,String> configMap = new HashMap<String,String>();
        configMap.put("merch","000001110100000812");
        configMap.put("path","F:/keypath/test_yufu_nonca.cer");
        System.out.println("configMap is  " + configMap);
        String jsonString = JSON.toJSONString(configMap);//Map转Json
        System.out.println("JSON.toJSONString(configMap) is  " + jsonString);
        String json = JsonUtils.toJson(configMap);//Map转Json
        System.out.println("JsonUtils.toJson(configMap) is  " + json);
        try{
            byte byteXl[]  = JSON.toJSONString(configMap).getBytes("UTF-8");
            System.out.println("configMap is  " + byteXl);
            Base64 encoder = new Base64();
            String encodedStr = encoder.encodeToString(byteXl);//Base64加密
            System.out.println("encodedStr is  " + encodedStr);
            String base64EncStr= new String (Base64.encodeBase64(byteXl),"UTF-8");//Base64加密
            System.out.println("base64EncStr is  " + base64EncStr);

            String dec =new String(encoder.decode(base64EncStr),"UTF-8") ;//Base64解密
            System.out.println("dec is  " + dec);
            String decData = new String(Base64.decodeBase64(base64EncStr),"UTF-8");//Base64解密
            System.out.println("decData is  " + decData);
            Map<String,String> mapData = (Map)JSON.parseObject(decData, new com.alibaba.fastjson.TypeReference<Map<String, String>>() {
            }, new Feature[0]);//Json转map
            System.out.println("mapData is  " + mapData);
        }catch(Exception e){
            e.printStackTrace();
        }
}
