1.JDK

sun.misc.BASE64Encoder/BASE64Decoder类不属于JDK标准库范畴，但在JDK中包含了该类，可以直接使用。

测试：

import org.junit.Test;
import sun.misc.BASE64Decoder;
import sun.misc.BASE64Encoder;

import java.io.IOException;

public class Base64Test {

    private String src="/upload/123.jsp";
    @Test
    public void JDKBase64(){
        //加密
        BASE64Encoder encoder = new BASE64Encoder();
        String encode = encoder.encode( src.getBytes() );
        System.out.println( "JDK--encode:" + encode );
        //解密
        BASE64Decoder decoder = new BASE64Decoder();
        try {
            byte[] decode = decoder.decodeBuffer( encode );
            System.out.println( "JDK--decode:" + new String( decode ) );
        } catch( IOException e ) {
            e.printStackTrace();
        }

    }
}

结果：

 

2.commons-codec

导入依赖：

    <dependency>
      <groupId>commons-codec</groupId>
      <artifactId>commons-codec</artifactId>
      <version>1.9</version>
    </dependency>

测试：

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


public class Base64Test {

    private String src="/upload/123.jsp";

    @Test
    public void commonsCodecBase64() {
        //加密
        byte[] encode = Base64.encodeBase64( src.getBytes() );
        System.out.println( "commons--encode:" + new String( encode ) );
        //解密
        byte[] decode = Base64.decodeBase64( encode );
        System.out.println( "commons--decode:" + new String( decode ) );
    }


}

结果：

3.bouncycastle

导入依赖：

    <dependency>
      <groupId>org.bouncycastle</groupId>
      <artifactId>bcprov-jdk15</artifactId>
      <version>1.46</version>
    </dependency>

测试：

import org.junit.Test;

public class Base64Test {

    private String src="/upload/123.jsp";

    @Test
    public void bouncyCastleBase64() {
        //加密
        byte[] encode = org.bouncycastle.util.encoders.Base64.encode( src.getBytes() );
        System.out.println( "bouncycastle--encode:" + new String( encode ) );
        //解密
        byte[] decode = org.bouncycastle.util.encoders.Base64.decode( encode );
        System.out.println( "bouncycastle--decode:" + new String( decode ) );
    }

}

结果：
