disconf中有哪些服務(wù)器內(nèi)部錯(cuò)誤
這篇文章給大家介紹disconf中有哪些服務(wù)器內(nèi)部錯(cuò)誤，內(nèi)容非常詳細(xì)，感興趣的小伙伴們可以參考借鑒，希望對(duì)大家能有所幫助。
專注于為中小企業(yè)提供做網(wǎng)站、成都做網(wǎng)站服務(wù),電腦端+手機(jī)端+微信端的三站合一,更高效的管理,為中小企業(yè)昌黎免費(fèi)做網(wǎng)站提供優(yōu)質(zhì)的服務(wù)。我們立足成都，凝聚了一批互聯(lián)網(wǎng)行業(yè)人才，有力地推動(dòng)了1000多家企業(yè)的穩(wěn)健成長(zhǎng)，幫助中小企業(yè)通過網(wǎng)站建設(shè)實(shí)現(xiàn)規(guī)模擴(kuò)充和轉(zhuǎn)變。
原因如下：
發(fā)版之前進(jìn)行修改
disconf配置中心的配置數(shù)據(jù)，結(jié)果發(fā)現(xiàn)disconf的XX項(xiàng)目配置中心管理界面的配置文件頁(yè)面為空。當(dāng)時(shí)就嚇壞了，以為是服務(wù)掛了，如果配置中心整個(gè)服務(wù)掛了就很嚴(yán)重了，馬上看了下別的項(xiàng)目的配置中心頁(yè)面是正常的， 唯獨(dú)XX項(xiàng)目的是空白，趕緊看了下XX項(xiàng)目的應(yīng)用日志，一切正常，由此馬上F12查看disconf后臺(tái)的請(qǐng)求，發(fā)現(xiàn)返回了一段json錯(cuò)誤信息，服務(wù)器內(nèi)部錯(cuò)誤。
進(jìn)入生產(chǎn)環(huán)境查看 disconf 的報(bào)錯(cuò)日志，發(fā)現(xiàn)報(bào)錯(cuò)表現(xiàn)很模糊：

由此猜測(cè)是新增了配置文件，但是配置文件可能配型或者值不對(duì)或者出現(xiàn)了特殊字符，導(dǎo)致了解析失敗了。
查了下應(yīng)用的配置中心的代碼，發(fā)現(xiàn)的確有新的配置文件且從生產(chǎn)數(shù)據(jù)庫(kù)和 zookeeper 撈出來的數(shù)據(jù)來看配置本身含有特殊字符，猜測(cè)是中文注釋,看了下我們自己的應(yīng)用代碼，發(fā)現(xiàn)開發(fā)人員使用了很奇怪的 Map 類型做 key 。
馬上靈機(jī)一動(dòng)在測(cè)試環(huán)境復(fù)現(xiàn)下這個(gè)問題，結(jié)果發(fā)現(xiàn)果然有辦法復(fù)現(xiàn)，觸發(fā)條件也和預(yù)想的一樣。
觸發(fā)條件： 使用 Map 類型，且首行使用中文注釋，且定義的 Map 類型在 disconf不設(shè)置值。
配置好了之后，刷新 disconf 配置頁(yè)面，發(fā)現(xiàn)頁(yè)面報(bào)錯(cuò) , 請(qǐng)求 disconf 返回json結(jié)果 服務(wù)器內(nèi)部錯(cuò)誤。
解決方案：
換一個(gè)配置文件名稱，去掉 Map 類型使用基本的 String 放置 json 數(shù)據(jù), 自己通過代碼轉(zhuǎn)換 json 為對(duì)象，刪除原配置文件，disconf 恢復(fù)正常。
根本原因沒有去找，實(shí)在是沒有時(shí)間去看 disconf 的源碼。。。
附上出問題的版本號(hào)：
disconf 版本： 2.6.30
關(guān)于disconf中有哪些服務(wù)器內(nèi)部錯(cuò)誤就分享到這里了，希望以上內(nèi)容可以對(duì)大家有一定的幫助，可以學(xué)到更多知識(shí)。如果覺得文章不錯(cuò)，可以把它分享出去讓更多的人看到。
