Cause of the problem: because the oracle driver needs official authorization, so directly in pop.xml configuration file could not be downloaded successfully.
Solution: By installing the driver package to a local maven repository, can solve this problem.
1. Enter the following commands in cmd maven
mvn install:install-file -DgroupId=com.oracle -DartifactId=ojdbc6 -Dversion=11.2.0.1.0 -Dpackaging=jar -Dfile=ojdbc6.jar
Wherein -Dfile = ojdbc6.jar the driver package is a relative path
After a successful installation can be used in pom.xml
