The problem is very much like no access to the address is wrong, the first feeling that the URL is not written.


In fact, the real reason is that the "Application boot class is misplaced" to put the application on the outermost layer, which is to include all the child packages.

Springboot automatically loads all the components under the package where the startup class is located and under its child packages.

After the investigation does not exist this problem, there are some other solutions are tried or not. Finally found on the spring website
