Access restriction错误

• 今日调用sun.misc.BASE64Decoder()与sun.misc.BASE64Encoder()方法时，eclipse报 Access restriction: The method encode(byte[]) from the type CharacterEncoder is not accessible due to restriction on required library ….(jre的 rt.jar 地址)

  • 这个问题就百度了一下，原来是eclipse设置问题，只要在
  • windows–>preferences–>Java–>Compiler–>Errors/Warnings中，找到Deprecated and restricted API，将当中的Forbidden references(access rules) 设为Warning即可
