修改项目字符编码

File -> Setting -> Editor -> File Encodings   改成UTF-8

1.自动优化导入

File -> Setting -> Editor -> Auto Import ->  |✔| Optimize imports on the fly

2.左侧项目树，隐藏无用文件

 

 

 

3.多模块项目展示 Services 窗口

修改 项目文件目录 -> .idea -> workspace.xml 文件，找到 RunDashboard 节点，做如下修改

<component name="RunDashboard">
    <option name="configurationTypes">
      <set>
        <option value="SpringBootApplicationConfigurationType" />
      </set>
    </option>
    <option name="ruleStates">
      <list>
        <RuleState>
          <option name="name" value="ConfigurationTypeDashboardGroupingRule" />
        </RuleState>
        <RuleState>
          <option name="name" value="StatusDashboardGroupingRule" />
        </RuleState>
      </list>
    </option>
  </component>
