Just use the idea soon, when added to the class @SpringBootApplication notes, the system actually does not automatically prompt, carefully check the maven dependencies and libararies a corresponding jar package and found no problems. Finally, note that the IDE is suggesting more sensitive to typing case.
The solution is to give online setting-> Code Completion-> Case sensitive completion content selection box to select None, but my version 18 idea seems does not have this option, as shown in the specific interface shown in
the present method is actually set Match case is to the front of the box to remove the check mark, then click the apply button.
With the IDE version of the update, configure many settings there may be some differences, but the central design idea is certainly not likely to become, then we need to more carefully, to try, in the process, perhaps more than once you set successfully come to be more impressive, why not.
