Java 8——Base64工具
在java 8之前如果需要使用base64编解码,必须使用三方库,如:apache的commons-codec。
但是java 8将base64编解码的工具引入进来:
public class TestBase64 {
public static void main(String[] args) {
String plainTxt = "i love you!";
String secure = base64Encode(plainTxt);
base64Decode(secure);
}
public static String base64Encode(String plainTxt) {
byte[] bytes = Base64.getEncoder().encode(plainTxt.getBytes());
String secureTxt = new String(bytes);
System.out.println(secureTxt);
return secureTxt;
}
public static void base64Decode(String secureTxt) {
byte[] bytes = Base64.getDecoder().decode(secureTxt.getBytes());
String plainTxt = new String(bytes);
System.out.println(plainTxt);
}
}
执行结果:
