背景：
業(yè)務(wù)場景：MySQL數(shù)據(jù)庫定期從Oracle數(shù)據(jù)庫中同步少量數(shù)據(jù)，幾分鐘一次
版本信息：服務(wù)器jdk1.8.0_171，開發(fā)編譯環(huán)境jdk1.8.0_181 idea2023.1.2
技術(shù)框架：用了maven管理依賴，未發(fā)現(xiàn)spring等框架痕跡
問題描述
將代碼少量改動后，本地編譯外加依賴打成jar包。
部署到遠(yuǎn)程服務(wù)器時(shí)，運(yùn)行出錯，系統(tǒng)中查看報(bào)錯信息:
出錯原因：
java.lang.reflect.InvocationTargetException
原因分析：
差不多的代碼，原有jar包在別的服務(wù)器可運(yùn)行，說明是環(huán)境問題，搜索發(fā)現(xiàn)
原因：
1、包沖突、有重復(fù)包或者缺少包
2、項(xiàng)目jdk和部署jdk版本不一樣，導(dǎo)致InvocationTargetException異常信息返回一個(gè)空值，沒有調(diào)用invoc里的重寫消息方法。
3、映射文件發(fā)生改變
方案：
1、包：直接自己挨著查看就是了，但是一定要注意遇到重復(fù)包的時(shí)候你的系統(tǒng)究竟需要哪一個(gè)版本
2、jdk版本：
⑴、更換jdk包
⑵、用一個(gè)方法統(tǒng)一處理該異常
3、映射文件發(fā)生改變
在項(xiàng)目中有的地方是使用反射機(jī)制進(jìn)行的操作，可能對于類進(jìn)行了某些更改，科室映射文件沒有更改，采用匿名就會出現(xiàn)這樣的問題，解決辦法要么更改映射文件，要不不要使用匿名調(diào)用。
原文鏈接
由此推測是jdk版本不一致的原因，嘗試將開發(fā)環(huán)境與生產(chǎn)環(huán)境用同版本jdk
解決方案：
方案一：更換jdk重新打包再部署（未實(shí)驗(yàn)，方案二可行則本方案理論上也可行）
方案二：更換jdk后重新編譯，把改動代碼的編譯后的class文件放入原有可運(yùn)行jar包（注意修改IP端口賬號密碼等配置）
- 加裝jdk
從項(xiàng)目文件中找到171版本jdk進(jìn)行安裝，原有jdk無須理會，環(huán)境變量也不用修改 -
ctrl+alt+shift+s打開項(xiàng)目配置
project》sdk》add sdk 添加剛剛安裝的jdk - 點(diǎn)擊project下方的module選項(xiàng)卡
切換各個(gè)模塊的sdk - 點(diǎn)擊platforms and settings
選中原有的jdk，點(diǎn)擊上方減號，從項(xiàng)目中去掉
新添加的jdk保留不動，點(diǎn)擊apply應(yīng)用，然后確定 - maven插件重新打包，發(fā)送到服務(wù)器
- 用壓縮軟件打開新包，把修改過的class文件覆蓋到舊包中保存
- 運(yùn)行成功
重逢再回首之2023年8月3日
背景
業(yè)務(wù)場景：依舊是同步任務(wù)，定期夸庫同步少量數(shù)據(jù)，這次完全是在開發(fā)環(huán)境中
版本信息：jdk1.8.0_171 idea2023.1.2 MySQL5.6
技術(shù)框架：springboot上的若依系統(tǒng)二開
數(shù)據(jù)庫是三庫結(jié)構(gòu)，一個(gè)源數(shù)據(jù)庫Oracle，一個(gè)中間庫MySQL，一個(gè)業(yè)務(wù)庫MySQL
問題出現(xiàn)之前，將master和第三數(shù)據(jù)源做過對換，系統(tǒng)能運(yùn)行，但是當(dāng)時(shí)沒有調(diào)測任務(wù)能不能成功運(yùn)行
問題描述
新寫了一個(gè)同步任務(wù)，之前用的jdk1.8.0_171，能成功運(yùn)行，這次突然不行了

原因分析
推測還是老問題，jdk版本，重新改一下jdk到181，這次我學(xué)聰明了，只添加181，不刪除171，因?yàn)檫@里搞得jdk會影響其他項(xiàng)目（奇怪，明明只是項(xiàng)目配置，按理說相互之間不能影響的）
當(dāng)然，沒有解決這個(gè)問題，就算是只保留一個(gè)181jdk也不行了，果然和預(yù)感一樣，沒這么簡單。
再次觀察控制臺錯誤日志，發(fā)現(xiàn)同步任務(wù)可以執(zhí)行，但是service方法里的第一個(gè)斷點(diǎn)都沒進(jìn)（我用debug模式啟動的），看來是框架service這邊的問題，Java基礎(chǔ)框架原理真的重要??！
突然回想起來，有個(gè)mapper好像沒加mapper注解，倒是很像這個(gè)問題，但是加了也不行，根本就沒運(yùn)行到這里。
但是啊，但是，這里還有個(gè)空指針異常，看來根本就沒裝配上這個(gè)service。
stackoverflow上有同時(shí)出現(xiàn)這兩個(gè)異常的問題，但他是因?yàn)榘炎詣幼⑷氲淖兞繉懗闪遂o態(tài)的所以才出的問題，啟發(fā)給我的點(diǎn)就是檢查一下調(diào)用的service方法是否在接口中有定義，但是這個(gè)很明顯不是，因?yàn)榻涌跊]有的話我就沒法調(diào)用了。
在帖子里的評論有一個(gè)鏈接，講了一些關(guān)于注解的東西，看了一點(diǎn)，有空再來看看
直覺告訴我，一定是哪里沒有用框架組件（component、service、mapper等），或者是哪里沒有用注解聲明組件，但是之前檢查出來了mapper注解漏了一個(gè)，別的就沒再有了，查看定時(shí)任務(wù)類的上方，也是有注解的：
@Component("syncTask")
解決方案
既然定時(shí)任務(wù)這里注冊組件了，那系統(tǒng)的定時(shí)任務(wù)配置，是不是應(yīng)該也用組件來調(diào)用呢？
再次回到系統(tǒng)中，果然發(fā)現(xiàn)：
果然，是我寫的調(diào)用目標(biāo)寫的不對，上邊的都短我竟然沒發(fā)現(xiàn)。
修改調(diào)用目標(biāo)，寫上從組件開始調(diào)用的任務(wù)，問題消失
插曲
因?yàn)轫?xiàng)目的主要功能是同步，數(shù)據(jù)有點(diǎn)bug，本來應(yīng)該是唯一的，源數(shù)據(jù)中有重復(fù)數(shù)據(jù)，這只能怪自己考慮不周。 在數(shù)據(jù)重復(fù)時(shí)，利用j8stream語法轉(zhuǎn)換list為map時(shí)會報(bào)錯：文章來源：http://www.zghlxwxcb.cn/news/detail-761085.html
