sun.misc.BASE64Encoder找不到jar包的解决方法

Posted 2020-11-19 小屈工作室

1.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！！！

2.

在MyEclipse中编写Java代码时，用到了BASE64Decoder，import sun.misc.BASE64Decoder；可是Eclipse提示： 
Access restriction: The type BASE64Decoder is not accessible due to restriction on required library C:Program 
filesjavajre6lib t.jar 
Access restriction : The constructor BASE64Decoder() is not accessible due to restriction on required library C:Program filesjavajre6lib t.jar 

解决方案1（推荐）： 
只需要在project build path中先移除JRE System Library，再添加库JRE System Library，重新编译后就一切正常了。 
解决方案2： 
Windows -> Preferences -> Java -> Compiler -> Errors/Warnings -> 
Deprecated and trstricted API -> Forbidden reference (access rules): -> change to warning

 

 

我用的是移除jre System Library,再添加库
