1.配置文件格式

Exception in thread "main" org.hibernate.HibernateException: Error accessing stax stream
    at org.hibernate.boot.cfgxml.internal.JaxbCfgProcessor.unmarshal(JaxbCfgProcessor.java:107)
    at org.hibernate.boot.cfgxml.internal.JaxbCfgProcessor.unmarshal(JaxbCfgProcessor.java:65)
    at org.hibernate.boot.cfgxml.internal.ConfigLoader.loadConfigXmlResource(ConfigLoader.java:57)
    at org.hibernate.boot.registry.StandardServiceRegistryBuilder.configure(StandardServiceRegistryBuilder.java:163)
    at org.hibernate.cfg.Configuration.configure(Configuration.java:258)
    at com.nick.view.TestMain.main(TestMain.java:17)
Caused by: javax.xml.stream.XMLStreamException: ParseError at [row,col]:[1,3]

    at org.hibernate.boot.cfgxml.internal.JaxbCfgProcessor.unmarshal(JaxbCfgProcessor.java:103)

出现这个错误通常是在项目里hibernate.cfg.xml 或者其他hibernate相关的xml配置文件

<?xml version="1.0" encoding="utf-8"?>

2.响应数据库驱动 jar 没有导入

报错信息：

Exception in thread "main" org.hibernate.service.spi.ServiceException: Unable to create requested service [org.hibernate.engine.jdbc.env.spi.JdbcEnvironment]
