报错这个错，找了半天不知所云，总以为是驱动有问题，后来看到说jdbcUrl格式可能有问题，我的下发如下：
<property name="jdbcUrl">
<value>
jdbc:mysql://127.0.0.1:3306/NetCourse
</value>
</property>
改成:
<property name="jdbcUrl">
<value>jdbc:mysql://127.0.0.1:3306/NetCourse</value>
</property>
然后就不报这个错误了，这也算问题，我靠。
另附Oracle12c在Hibernate底下的配置：
#application configs
#jdbc c3p0 config
jdbc.driver=oracle.jdbc.driver.OracleDriver
jdbc.url = jdbc:oracle:thin:@//10.8.8.70:1521/shdb
jdbc.username = ecrm
jdbc.password = ecrm #hibernate config
hibernate.dialect = org.hibernate.dialect.OracleDialect
#hibernate.dialect=org.hibernate.dialect.Oracle9Dialect
hibernate.show_sql = true
hibernate.format_sql = false
hibernate.hbm2ddl.auto = update
hibernate.cache.use_second_level_cache = true
hibernate.cache.use_query_cache = true
hibernate.cache.region.factory_class = org.hibernate.cache.ehcache.EhCacheRegionFactory
hibernate.cache.provider_configuration_file_resource_path = ehcache.xml
