Eclipse error:Access restriction

 

报错:
Access restriction: The method decodeBuffer(String) from the type CharacterDecoder is not accessible due to restriction on required library


Access restriction: The constructor BASE64Decoder() is not accessible due to restriction on required library

Access restriction: The type BASE64Decoder is not accessible due to restriction on required library

 

解决方法: 
这是eclipse设置问题,eclipse默认把这些受访问限制的API设成了ERROR,只要把 
Window-Preferences-Java Complicer-Errors/Warnings 
里面的Deprecated and restricted API中的Forbidden references(access rules)设置为Warning即可。

 

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
