=== Configuring Sentinel Circuit Breakers
|
||||
|
||||
==== Default Configuration
|
||||
|
||||
To provide a default configuration for all of your circuit breakers create a `Customizer` bean that is passed a
|
||||
`SentinelCircuitBreakerFactory` or `ReactiveSentinelCircuitBreakerFactory`.
|
||||
The `configureDefault` method can be used to provide a default configuration.
|
||||
|
||||
====
|
||||
[source,java]
|
||||
----
|
||||
@Bean
|
||||
public Customizer<SentinelCircuitBreakerFactory> defaultCustomizer() {
|
||||
return factory -> factory.configureDefault(id -> new SentinelConfigBuilder(id)
|
||||
.build());
|
||||
}
|
||||
----
|
||||
====
|
||||
|
||||
You can choose to provide default circuit breaking rules via `SentinelConfigBuilder#rules(rules)`.
|
||||
You can also choose to load circuit breaking rules later elsewhere using
|
||||
`DegradeRuleManager.loadRules(rules)` API of Sentinel, or via Sentinel dashboard.
