kymtwyf / compiler.xml in intellij.md
Created January 5, 2016 16:32 
  <excludeFromCompile>
    <file url="file://$PROJECT_DIR$/src/main/java/xxxController.java" />
  </excludeFromCompile>

由于误操作（我也不知道什么时候干的）发现这个 controller 下面的 api无法访问`No mapping found for HTTP request with URI /...` 
然后发现没有其他代码更变。只有一个在.idea 下面的 compiler.xml 里多了一句这个。手动删除却发现下次又生成了，所以查找了配置在(Preferences[command+,] -> Compiler ->Excludes ）下找到了。。。
