一、db.url=jdbc:mysql://127.0.0.1:3306/xxx数据库名称?characterEncoding=utf8&connectTimeout=1000&socketTimeout=3000&autoReconnect=true&serverTimezone=UTC

二、jdbc:mysql://xxx:3306/xxx数据库名称?useUnicode=true&characterEncoding=UTF-8&serverTimezone=GMT

三、jdbc:mysql://127.0.0.1:3306/库名?useUnicode=true&characterEncoding=utf8&characterSetResults=utf8&serverTimezone=UTC

四、带允许检索公匙参数(mysql8.0.x需要)
