問(wèn)題產(chǎn)生：我配置在linux上的tomcat服務(wù)器生成圖片時(shí)中文，出現(xiàn)很多小方框，不能正常顯示。
問(wèn)題解決過(guò)程：通過(guò)網(wǎng)絡(luò)上搜索資料，發(fā)現(xiàn)是因?yàn)閘inux上jre對(duì)中文支持的問(wèn)題。后來(lái)發(fā)現(xiàn)這篇小文章：

JDK 6 for linux的中文問(wèn)題
在linux下做java開發(fā)已經(jīng)好幾年了，經(jīng)歷了jdk1.4 -> 6.0。看著java在linux下的中文問(wèn)題已經(jīng)在慢慢改善。到6.0不做任配置都已經(jīng)能正常運(yùn)行很多中文程序，但可惜還是會(huì)有些中文問(wèn)題。例如運(yùn)行 jedit, netbeans等程序。甚至是自己寫的hello world swing程序的系統(tǒng)菜單都是亂碼的。
但解決方法很簡(jiǎn)單，在JRE 5以上的java環(huán)境中，java會(huì)自動(dòng)加載$JAVA_HOME/jre/lib/fonts/fallback目錄下的字體。鏈接或復(fù)制宋體或微軟雅黑等字體到該目錄即可解決。
但官方文檔上說(shuō)此法只適用于swing程序，要讓awt程序也支持中文，還要自己設(shè)字體配置文件。由于我很少會(huì)用到awt程序，也就懶得去改了，有需要的朋友請(qǐng)參考Font Configuration Files
進(jìn)行操作：
在Windows XP的字體目錄下，找到simsun.ttc的字體文件，重命名為simsun.ttf，然后將該文件復(fù)制到linux的/usr/local/jdk/jre/lib/fonts/fallback/（這個(gè)fallback目錄如果不存在則先創(chuàng)建這個(gè)目錄）下面，因?yàn)?simsun.ttf 字體文件對(duì)應(yīng)的是宋體，則在程序中使用的時(shí)候設(shè)置字體為“宋體”，修改fonts.dir為以下內(nèi)容。
