我的问题如下.我正在学习如何使用JDBC,Gradle和Spring框架(我对这些主题不熟悉).我一直试图实现以下example与一个区别,MysqL数据库而不是Postgresql.
就像我在标题中指定的那样,我的应用程序以以下错误结束无法加载驱动程序类:com.MysqL.jdbc.Driver(帖子末尾的堆栈跟踪).
当然我在发布这个问题之前一直在谷歌搜索和阅读,我发现com.MysqL.jdbc.Driver应该在程序中使用loader加载,或者也可以使用Gradle构建脚本来完成.
我的问题如下:
>为什么作者示例在没有加载器的情况下工作(在构建脚本中的程序中)
>如果加载器是绝对必要的,你能简要解释一下如何实现它吗?

编辑#1
正如Kamoor先生所说,这可能是缺少本地* jar文件的问题.我怀疑Gradle会自动从存储库下载它,万一我不会手动添加它(我在STS上工作).在这里我们可以看到MysqL-connector-java jar就在那里.
我很抱歉这些屏幕拍摄,我只是不知道其他方式来表明我添加它(我不习惯Eclipse).
最佳答案
我通过反复试验解决了这个问题.它对我来说是删除驱动程序引用表单application.properties文件.所以我的application.properties文件看起来像这样,错误立即消失:
原文链接:https://www.f2er.com/spring/432054.htmlspring.datasource.url = jdbc:MysqL://localhost:3306/test
spring.datasource.username = root
spring.datasource.password = fake
#spring.datasource.driver-class-name = com.MysqL.jdbc.Driver
mybatis.config=mybatis-config.xml
mybatis.check-config-location=true
我认为这与您在嵌入式Tomcat中需要该驱动程序的概率有关,而与应用程序代码本身无关
