[Waylon-Firework]

Question

Version: 5.4.0

if I set some properties, the app cannot restart. Such as:

database_url: localhost:3306

and using it like this: ${database_url} .

I can't declare custom attributes

database_url: localhost:3306

dataSources:
  demo:
    dataSourceClassName: com.alibaba.druid.pool.DruidDataSource
    url: jdbc:mysql://${database_url}/demo

The database_url configuration does not exist in ShardingSphere. The ${database_url} not support, you can use ShardingSphereDriver to use ShardingSphere-JDBC.

• I think this was superseded by Add ClasspathURLProvider implementation that reads system properties #29995 .
• Refer to https://shardingsphere.apache.org/document/current/en/user-manual/shardingsphere-jdbc/yaml-config/jdbc-driver/known-implementation/#load-configuration-file-containing-system-properties-from-classpath .
