背景:
业务场景:MySQL数据库定期从Oracle数据库中同步少量数据,几分钟一次
版本信息:服务器jdk1.8.0_171,开发编译环境jdk1.8.0_181 idea2023.1.2
技术框架:用了maven管理依赖,未发现spring等框架痕迹
问题描述
将代码少量改动后,本地编译外加依赖打成jar包。
部署到远程服务器时,运行出错,系统中查看报错信息:
出错原因:
java.lang.reflect.InvocationTargetException
原因分析:
差不多的代码,原有jar包在别的服务器可运行,说明是环境问题,搜索发现
原因:
1、包冲突、有重复包或者缺少包
2、项目jdk和部署jdk版本不一样,导致InvocationTargetException异常信息返回一个空值,没有调用invoc里的重写消息方法。
3、映射文件发生改变
方案:
1、包:直接自己挨着查看就是了,但是一定要注意遇到重复包的时候你的系统究竟需要哪一个版本
2、jdk版本:
⑴、更换jdk包
⑵、用一个方法统一处理该异常
3、映射文件发生改变
在项目中有的地方是使用反射机制进行的操作,可能对于类进行了某些更改,科室映射文件没有更改,采用匿名就会出现这样的问题,解决办法要么更改映射文件,要不不要使用匿名调用。

由此推测是jdk版本不一致的原因,尝试将开发环境与生产环境用同版本jdk
解决方案:
方案一:更换jdk重新打包再部署(未实验,方案二可行则本方案理论上也可行)
方案二:更换jdk后重新编译,把改动代码的编译后的class文件放入原有可运行jar包(注意修改IP端口账号密码等配置)
- 加装jdk
从项目文件中找到171版本jdk进行安装,原有jdk无须理会,环境变量也不用修改 -
ctrl
+alt
+shift
+s
打开项目配置
project》sdk》add sdk 添加刚刚安装的jdk - 点击project下方的module选项卡
切换各个模块的sdk - 点击platforms and settings
选中原有的jdk,点击上方减号,从项目中去掉
新添加的jdk保留不动,点击apply应用,然后确定 - maven插件重新打包,发送到服务器
- 用压缩软件打开新包,把修改过的class文件覆盖到旧包中保存
- 运行成功
重逢再回首之2023年8月3日
背景
业务场景:依旧是同步任务,定期夸库同步少量数据,这次完全是在开发环境中
版本信息:jdk1.8.0_171 idea2023.1.2 MySQL5.6
技术框架:springboot上的若依系统二开
数据库是三库结构,一个源数据库Oracle,一个中间库MySQL,一个业务库MySQL
问题出现之前,将master和第三数据源做过对换,系统能运行,但是当时没有调测任务能不能成功运行
问题描述
新写了一个同步任务,之前用的jdk1.8.0_171,能成功运行,这次突然不行了

原因分析
推测还是老问题,jdk版本,重新改一下jdk到181,这次我学聪明了,只添加181,不删除171,因为这里搞得jdk会影响其他项目(奇怪,明明只是项目配置,按理说相互之间不能影响的)
当然,没有解决这个问题,就算是只保留一个181jdk也不行了,果然和预感一样,没这么简单。
再次观察控制台错误日志,发现同步任务可以执行,但是service方法里的第一个断点都没进(我用debug模式启动的),看来是框架service这边的问题,Java基础框架原理真的重要啊!
突然回想起来,有个mapper好像没加mapper注解,倒是很像这个问题,但是加了也不行,根本就没运行到这里。
但是啊,但是,这里还有个空指针异常,看来根本就没装配上这个service。
stackoverflow上有同时出现这两个异常的问题,但他是因为把自动注入的变量写成了静态的所以才出的问题,启发给我的点就是检查一下调用的service方法是否在接口中有定义,但是这个很明显不是,因为接口没有的话我就没法调用了。
在帖子里的评论有一个链接,讲了一些关于注解的东西,看了一点,有空再来看看
直觉告诉我,一定是哪里没有用框架组件(component、service、mapper等),或者是哪里没有用注解声明组件,但是之前检查出来了mapper注解漏了一个,别的就没再有了,查看定时任务类的上方,也是有注解的:
@Component("syncTask")
解决方案
既然定时任务这里注册组件了,那系统的定时任务配置,是不是应该也用组件来调用呢?
再次回到系统中,果然发现:
果然,是我写的调用目标写的不对,上边的都短我竟然没发现。
修改调用目标,写上从组件开始调用的任务,问题消失
插曲
因为项目的主要功能是同步,数据有点bug,本来应该是唯一的,源数据中有重复数据,这只能怪自己考虑不周。 在数据重复时,利用j8stream语法转换list为map时会报错:文章来源:https://www.toymoban.com/news/detail-761085.html
