springboot 下类转换异常

最近手痒在代码里加了devtools 然后刚好定时任务中有个强制类转换，于是类转换异常的BUG出来了，百思不得其解，差点自闭，最后定位到原因，是多加了devtools导致的
Spring的dev-tools为了实现重新装载class自己实现了一个类加载器，来加载项目中会改变的类，方便重启时将新改动的内容更新进来，其实其中官方文档中是有做说明的：
By default, any open project in your IDE will be loaded using the
“restart” classloader, and any regular .jar file will be loaded using
the “base” classloader. If you work on a multi-module project, and not
each module is imported into your IDE, you may need to customize
things. To do this you can create a
META-INF/spring-devtools.properties file.
The spring-devtools.properties file can contain restart.exclude. and
restart.include. prefixed properties. The include elements are items
that should be pulled up into the “restart” classloader, and the
exclude elements are items that should be pushed down into the “base”
classloader. The value of the property is a regex pattern that will be
applied to the classpath.
解决办法：
第一种解决方案：在resources目录下面创建META_INF文件夹，然后创建spring-devtools.properties文件，文件加上类似下面的配置：
restart.exclude.companycommonlibs=/mycorp-common-[\w-]+.jar
restart.include.projectcommon=/mycorp-myproj-[\w-]+.jar

第二种解决方案：不使用spring-boot-devtools，因为这东西确实挺鸡肋，ctrl+shift+F9差不多得了
