2. Background

1. Learning Spring
   1. Scenes
      1. In some cases, completely change the class, you need to restart

      1. Restart
         1. This restart, first of all much more quickly than restart
            1. Because Spring class loader with two
            2. Restart, then only one restart, just in general is that Java code
   2. Automatic compilation
      1. This frequency may sometimes be less good control
         1. time
         2. Storage
      2. But if I want to change multiple files at once, and then restart
         1. Is not the case, there will be more to restart a few times ...
         2. If the project is large, it will not be too much trouble
