Base64加密解密工具类

使用Apache commons codec类Base64进行加密解密

maven依赖

<dependency>
    <groupId>commons-codec</groupId>
    <artifactId>commons-codec</artifactId>
    <version>1.6</version>
</dependency>

代码实现

package com.ljq.durian.common.util;

import java.io.UnsupportedEncodingException;

import org.apache.commons.codec.binary.Base64;
import org.apache.log4j.Logger;

        return null;
    }
