http://localhost:35620/api/error

訪問(wèn)首頁(yè)，會(huì)請(qǐng)求繪制驗(yàn)證碼，但是在繪制的時(shí)候，輸出了 http://localhost:35620/api/error 這個(gè)。在windows 下面不會(huì)跳轉(zhuǎn)到error頁(yè)面，能成功登入，部署到linux上面，立馬跳轉(zhuǎn)到error頁(yè)面。

我debug的時(shí)候，發(fā)現(xiàn)在執(zhí)行完

 BufferedImage image = new BufferedImage(width, height, BufferedImage.TYPE_INT_RGB);

這條語(yǔ)句時(shí)，就會(huì)出錯(cuò)，但是出錯(cuò)的原因完全不清楚。

備注：嵌入式的服務(wù)器用的是 undertow，不是用tomcat

有點(diǎn)惡心我配置了錯(cuò)誤頁(yè)面。發(fā)布到線上環(huán)境時(shí)，因?yàn)樵谔D(zhuǎn)至首頁(yè)的時(shí)候，用了絕對(duì)路徑。例如 modelAndView.setViewName("/login")。線上環(huán)境應(yīng)該使用相對(duì)路徑，例如 modelAndView.setViewName("login")。這個(gè)才是正確的。然后今天我重新啟動(dòng)，發(fā)現(xiàn)竟然控制臺(tái)沒(méi)有打印 localhost/api/error 了。。。。無(wú)語(yǔ)啊~
