1、不显示服务面板。
解决方法1：点击视图菜单，然后点击 工具窗口、服务 即可。如果服务中不显示微服务，是由于项目无法正常编译导致的。正常编译后，重新加载项目，IDEA会提示是否使用服务面板。选择使用，服务面板中会显示所有微服务。
解决方法2：文件、设置、插件，启用Spring和Spring Boot。编辑.idea/workspace.xml，查找
<component name="RunDashboard">
<option name="configurationTypes">
<set>
<option value="SpringBootApplicationConfigurationType" ></option>
</set>
</option>
</component>
2、运行微服务报错：Command line is too long. Shorten command line for XXXApplication or also for Spring Boot default configuration.。
点击XXXApplication超链接，在打开的编辑配置窗口里，展开Environment，缩短命令行选择JAR manifest或classpath file。
3、Maven面板双击clean报错：Process Terminated。
将maven的bin目录添加到Path变量中，在PowerShell中打开项目文件夹，执行 mvn clean，看看是否报错。

由错误可知，是找不到 org.springblade.platform:blade-bom:pom:2.9.0.RELEASE 导致的。
在项目根目录的 pom.xml 文件夹，添加 maven私有仓库。在pom.xml上右键，重新加载项目。问题解决。

解决方法：在包含main方法的类CompanyApplication上右键，然后运行，会提示命令行超长。编辑配置，在环境中选择缩短命令行后，成功运行。
5、IDEA社区版服务窗口只能显示5个服务。
在选择项目窗口，点击自定义、所有设置。在弹出的设置窗口中，点击左侧高级设置，在右边找到运行/调试，把 临时配置限制 由5改成100即可。
6、IDEA社区版服务窗口添加服务，缺少类型。
在菜单 Run / Edit Configurations... 中修改，拖动还可以改变服务的顺序。
