修改 entities 后，启动报错：

执行 mvn liquibase:clearCheckSums，报错如下：

[ERROR] Failed to execute goal org.liquibase:liquibase-maven-plugin:3.5.5:diff (default-cli) on project mirana: Error setting up or running Liquibase: liquibase.exception.DatabaseException: java.sql.SQLException: Access denied for user 'root'@'localhost' (using password: YES) -> [Help 1]

看报错是 liqiubase 没权限访问数据库，找到 pom.xml，配置 liqiubase。

<configuration>
                    <changeLogFile>src/main/resources/config/liquibase/master.xml</changeLogFile>
                    <diffChangeLogFile>src/main/resources/config/liquibase/changelog/${maven.build.timestamp}_changelog.xml</diffChangeLogFile>

添加密码。然后再次执行：mvn liquibase:clearCheckSums。执行完后，启动服务即可。
