排错：Command line is too long. Shorten the command line and retun，命令行过长。

Idea运行时报错：

解决办法：
修改项目下 .idea/workspace.xml，找到标签 <component name="PropertiesComponent"> ， 在标签里 加一行"dynamic.classpath": "true"

  <component name="PropertiesComponent"><![CDATA[{
  "keyToString": {
    "dynamic.classpath": "true",
    "RequestMappingsPanelOrder0": "0",
