解决bug--maven 仓库无法下载 sqljdbc41 的问题

时间：2022-06-20 01:30:39

最近做项目遇到一个问题，忙活了两三个小时，总算解决了，这里记录一下

 

这个项目在本地启动的时候能正常运行的，但打包放到 tomcat 的 webapps 目录下，发现解压报错了，我一开始看前面的错误是这样的

 但是我认真检查了 alertLogDao，alertLogService，alertLogService，发现 bean 都成功注入了，后来我又看到下面的日志，发现下面报的是 sqlSessionFactory 错误，这是找不到数据源啊

 我就去看 pom 文件是否引入了对应的 jar 包，发现引入 sqljdbc 的 dependency 是这么写的

<dependency>
   <groupId>com.microsoft.sqlserver</groupId>
   <artifactId>sqljdbc41</artifactId>
   <version>6.0.8112</version>
   <scope>system</scope>
   <systemPath>${project.basedir}/libs/sqljdbc41-6.0.8112.jar</systemPath>
</dependency>

也就是说 sqljdbc 的 jar 包是从本地路径取的，那么项目打成 jar 包时，是否把这个 jar 包打进来了呢，我看了 tomcat 解压后的文件，发现 WEB-INF/lib 文件夹下确实没有 sqljdbc41-6.0.8112.jar ，但反而在 WEB-INF/lib-provided 目录下有，这点很奇怪。

我就把 dependency 改成了下面这个，在网上下载 jar 包，手动安装 jar 包到 maven 仓库就可以了

<dependency>
   <groupId>com.microsoft.sqlserver</groupId>
   <artifactId>sqljdbc41</artifactId>
   <version>6.0.8112</version>
</dependency>

手动安装命令

 

mvn install:install-file -DgroupId=com.microsoft.sqlserver -DartifactId=sqljdbc41 -Dversion=6.0.8112 -Dpackaging=jar -Dfile=D:mavenlocalJarsqljdbc41-6.0.8112.jar

 

-Dfile 的值是 jar 所在的位置

 

由于之前一直用的是 mysql 数据库，没怎么用 sqlserver 数据库，这个错误当时还解决了挺久，记录下来希望能为你们提供一些帮助
