Org.springframework.beans.factory.BeanCreationException:Error creating Bean with Name ' XXX ' exception when SSM integration causes and workarounds

SSM integration occurs when org.springframework.beans.factory.BeanCreationException:Error creating bean with Name ' XXX ' The cause of the exception and how to resolve it (only the following may occur, not all)

This exception is: Injection Bean failed exception, that is, the injected bean could not be found.

There are several possible reasons for this:

1.bean not annotated or annotated error

2. When the project is integrated, jar package conflicts

3. The ' XXX ' configuration has errors

Solution: 1,3 carefully check is that most of the people on the Internet should be 2 of this error, I should also be such a mistake, but do not know which jar package conflict, the simplest solution to direct the other person's pom.xml to use is (genius solution)
