Java 试图在Spring中使用远程连接连接到MySQL数据库

我正在尝试设置远程连接，以便我的本地计算机可以充当远程服务器。这是我的application.properties文件。运行它会抛出几个错误，我知道这与无法连接到数据库有关，但我不确定原因

    spring.datasource.url = jdbc:mysql://162.207.67.190:3306/groupprojects?
    spring.datasource.username = root
    spring.datasource.password = 
    spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5Dialect

    spring.jpa.show-sql=true
    spring.jpa.properties.hibernate.format_sql=true
    spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
    spring.jpa.database-platform=org.hibernate.dialect.MySQL5Dialect
    spring.jpa.hibernate.ddl-auto = update

我收到几个通信链路故障。从哪里开始有什么建议吗

这是我第一次尝试建立远程连接，所以我有点迷路了
