mvn flyway:migrate 执行报错

看readme文档
3. 运行数据库脚本，创建本地数据库

mvn flyway:migrate

如果需要使用 MySQL 数据库，运行脚本前修改两处配置

# src/main/resources/application.properties 
spring.datasource.url=jdbc:h2:~/community
spring.datasource.username=sa
spring.datasource.password=123

# pom.xml
<properties>
    <db.url>jdbc:h2:~/community</db.url>
    <db.user>sa</db.user>
    <db.password>123</db.password>
</properties>

然后我改成了，

src/main/resources/application.properties

spring.datasource.url=jdbc:mysql://localhost:3306/community?useUnicode=true&characterEncoding=utf8
spring.datasource.username=root
spring.datasource.password=123456
spring.datasource.driver-class-name=com.mysql.jdbc.Driver

pom.xml

jdbc:mysql://localhost:3306/community?useUnicode=true&characterEncoding=utf8 root 123456 ```

执行

mvn flyway:migrate

报错：

Failed to execute goal org.flywaydb:flyway-maven-plugin:5.2.4:migrate (default-cli) on project community: org.flywaydb.core.internal.exception.FlywaySqlException: 
[ERROR] Unable to obtain connection from database (jdbc:mysql://localhost:3306/community) for user 'root': Communications link failure

在sh窗口，通过 mysql -u root -p 输入123456是可以连接成功的
