des 加密中BASE64Encoder找不到jar包问题

用了一个des 加密中util工具类其中有用到BASE64Encoder这个类是位于rt.jar这个包下吧上百度上查的办法都是在build path 里边加入jre system library也确实是可行但是过一会jre system library就消失了我jdk用的1.8但是项目好像是基于1.6是这个原因么但是当我直接导入1.6的rt.jar时程序就根本运行不起来了一直launching。。。。

解决方案

解决方案二

需要sun.misc.BASE64Decoder.jar这个包
或者右键项目->属性->java bulid path->jre System Library->access rules->resolution选择accessible下面填上** 点击确定即可

解决方案三

用了上面所讲的方法后还是会出现这个错误

解决方案五

其实这个类就是在jre system library我当初也是报错但是添加这个库之后就没事了啊一劳永逸就把这个jar加到lib里
