Sentinel provides the following ways to configure the common items:
- JVM -D parameter
- properties file (since 1.7.0)
The project.name item should be configured with JVM -D parameter, while other items support both approaches.
Users can configure the path of the properties file via the -Dcsp.sentinel.config.file property item, which also supports files in classpath (such as classpath:sentinel.properties). Sentinel will attempt to read the configuration from the classpath:sentinel.properties file (the default charset is UTF-8).
Note: If you're using Spring Boot or Spring Cloud, you may leverage Spring Cloud Alibaba Sentinel to provide Sentinel configuration in your Spring config file directly.
