报错如上，datasource.properties写的是数据库的属性配置

db.driverLocation=C:\\Users\\Administrator\这里的斜杠漏了转义字符，运行时无法读取斜杠.m2\\repository\\mysql\\mysql-connector-java\\8.0.12\\mysql-connector-java-8.0.12.jardb.driverClassName=com.mysql.cj.jdbc.Driver

应该为：

db.driverLocation=C:\\Users\\Administrator\\.m2\\repository\\mysql\\mysql-connector-java\\8.0.12\\mysql-connector-java-8.0.12.jardb.driverClassName=com.mysql.cj.jdbc.Driver
