问题处在mysql驱动的版本问题上
出问题前使用的mysql是5.1.41

  
        <dependency>
            <groupId>org.hibernategroupId>
            <artifactId>hibernate-coreartifactId>
            <version>5.0.12.Finalversion>
        dependency>
        
        <dependency>
            <groupId>mysqlgroupId>
            <artifactId>mysql-connector-javaartifactId>
            <version>5.1.41version>
        dependency>

之后改成更高一些的版本

 <dependency>
           <groupId>mysqlgroupId>
           <artifactId>mysql-connector-javaartifactId>
           <version>8.0.17version>
       dependency>

改成更高版本后驱动就不能在使用过时的com.mysql.jdbc.Driver
改成com.mysql.cj.jdbc.Driver
