来来来，记录一下阿里云Maven中央仓库的坑，当然最主要还是自身pom.xml设置问题。

昨天项目启动还好好的，为什么今天项目一启动就报错了呢？(线上项目服务器没重启的话也是正常可以访问的，只要一重启线上服务器就会发现线上服务器Maven在编译的时候下载了很多新的jar包，当然，线上服务器maven的settings.xml配置文件和本地机子配置的同样使用的是阿里云的maven仓库)

项目是使用的是springboot框架

本地开发环境Maven远程仓库的settings.xml配置文件使用了国内的阿里云中央仓库地址(为了提高下载引入的Jar包速度，懂的都懂)

刚好今天人家阿里云Maven中央仓库更新了Mybatis最新的jar包，自己项目中的mybatis包也没有写指定版本，所以就导致阿里云Maven远程仓库更新了Mybatis的引入包，而自己项目的pom也导入了阿里云远程仓库的最新Mybatis包导致项目不兼容而导致启动报错

一步步排查原因：本地连接服务器mysql数据库   正常、springboot扫描Mapper.xml映射文件  正常、但是报错就是提示我需要sql工厂session属性，我就纳闷了，昨天啥都没动，项目启动还好好的，今天怎么就见鬼了呢

解决方法：

去找到项目中pom.xml的mybatis引入jar

        <dependency>
            <groupId>org.mybatis.spring.boot</groupId>
            <artifactId>mybatis-spring-boot-starter</artifactId>
            <version>RELEASE</version>
        </dependency>

看到项目中的mybatis的版本号设置了吗？  <version>RELEASE</version>

mybatis引入的jar包没有设置指定版本号，而是使用RELEASE最新发布的版本，所以当阿里云远程中央仓库发布了RELEASE的mybatis Jar包后，本地启动项目经过Maven编译启动后，自动下载阿里云远程的最新Mybatis的发布版本Jar引入导致项目不兼容

所以我这里要修改Mybatis使用指定版本号的jar包

使用了2.1.1版本的试试

        <dependency>
            <groupId>org.mybatis.spring.boot</groupId>
            <artifactId>mybatis-spring-boot-starter</artifactId>
            <version>2.1.1</version>
        </dependency>

设置好指定版本号后，Maven重新导入Jar包，启动项目成功！！！

以后还是尽量设置指定的版本号吧，别用RELEASE最新发布版本的Jar了。

我真的哭死，搞了一天排查原因.....
