intellij IDEA 14 时代码中@override 下划线
1.
In the Project Structure | Project dialog, change the Project language Level to 6.0 - @Override in interfaces.
2.
If your project has multiple modules, also check that every module uses language level 6 or above, or use the project’s language level (see Project Settings > Modules > xxx > Language level).
You may need to reload your project once it is modified.
