将logback的日志输出到数据库，groovy方案_logbackappender如何实现groovy-优快云博客

本文介绍了一种简单的方法，即将应用程序的日志输出到MySQL数据库中。通过定义一个特定的appender，可以轻松实现这一目标。此外，还展示了如何设置日志级别，并提供了数据库表结构示例。

将日志输出到数据库其实很简单，首先定义一个appender:

appender("DB", DBAppender) {
    connectionSource(DriverManagerConnectionSource) {
        driverClass = "com.mysql.cj.jdbc.Driver"
        user = "sample"
        password = "sample@chuyun"
        url = "jdbc:mysql://localhost:3306/test?zeroDateTimeBehavior=CONVERT_TO_NULL&useSSL=false&serverTimezone=Asia/Shanghai"
    }
}

注意，早些年的解决方案目前好像都不好使了。

另外，设置日志输出的级别：

root(INFO, ['FILE', 'DB'])

数据库的结构如下代码所示：
