The problem with the SPRINGMVC Maven project that idea builds up

1. When adding a jar package, there is a problem with adding a jar package, there is a red wavy line on the project node of the Pom.xml file

There is no problem with the MAVEN address referenced by the jar, which is an error

WORKAROUND: Delete the relevant jar package from the local repository and re-download

2, each jar package exists, still reported not find a class, although only reference the main jar package, because according to MAVEN management, will automatically download the dependency package, but also in the project referenced by the jar package check, this class does exist

Workaround: Under Project Struture, delete the artifacts and re-add
