日志配置

背景信息

ShardingSphere 使用 Logback 进行日志管理,内部采用 Java SPI 提供默认日志配置,用户可以使用 XML 文件来配置自定义日志输出,Proxy 将优先读取 conf 目录下的 logback.xml 提供的日志配置。

下面将介绍如何自定义日志配置。

操作步骤

  1. 新建 conf/logback.xml

根据需求自定义 logger 级别、pattern 等。

建议在配置示例的基础上进行修改

  1. 查看日志

ShardingSphere-Proxy 启动后,日志将输出到 logs 目录下,选择目标日志文件进行查看。

配置示例
