Linux下JDK漢字顯示為方框

keelort

解決方法如下：
1、在windows的字體目錄拷貝simsun.ttf文件（如果是simsun.ttc你就復制成ttf吧）到JDK字體目錄
#cp simsun.ttf $JAVA_HOME/jre/lib/fonts
如果你的系統用simsun漢化過，這里添加一個simsun字體文件的軟鏈接也可以。
2、修改$JAVA_HOME/jre/lib/fonts/fonts.dir(此文件為只讀，需要修改屬性才能修改)文件內容，記得要先做個備份呀，將每行的原來的字體改成simsun.ttf吧
以下有個例子：

可以使用vi來一次全部替換 :%s/.*ttf/simsun.ttf
3、再次啟動JAVA程序，界面就能顯示中文了。
