the builder

preCreateProcessor

public void preCreateProcessor()

Description copied from class: ProcessorDefinition

Strategy to execute any custom logic before the Processor is created.

Overrides:

getResilience4jConfiguration

public Resilience4jConfigurationDefinition getResilience4jConfiguration()

setResilience4jConfiguration

public void setResilience4jConfiguration(Resilience4jConfigurationDefinition resilience4jConfiguration)

getFaultToleranceConfiguration

public FaultToleranceConfigurationDefinition getFaultToleranceConfiguration()

setFaultToleranceConfiguration

public void setFaultToleranceConfiguration(FaultToleranceConfigurationDefinition faultToleranceConfiguration)

getConfiguration

public String getConfiguration()

setConfiguration

public void setConfiguration(String configuration)

Refers to a circuit breaker configuration (such as resillience4j, or microprofile-fault-tolerance) to use for configuring the circuit breaker EIP.

getOnFallback

public OnFallbackDefinition getOnFallback()

setOnFallback

public void setOnFallback(OnFallbackDefinition onFallback)

resilience4jConfiguration

public Resilience4jConfigurationDefinition resilience4jConfiguration()

Configures the circuit breaker to use Resilience4j.

Use end when configuration is complete, to return back to the Circuit Breaker EIP.

resilience4jConfiguration

public CircuitBreakerDefinition resilience4jConfiguration(Resilience4jConfigurationDefinition configuration)

Configures the circuit breaker to use Resilience4j with the given configuration.

faultToleranceConfiguration

public FaultToleranceConfigurationDefinition faultToleranceConfiguration()

Configures the circuit breaker to use MicroProfile Fault Tolerance.

Use end when configuration is complete, to return back to the Circuit Breaker EIP.

faultToleranceConfiguration

public CircuitBreakerDefinition faultToleranceConfiguration(FaultToleranceConfigurationDefinition configuration)

Configures the circuit breaker to use MicroProfile Fault Tolerance with the given configuration.

configuration

public CircuitBreakerDefinition configuration(String ref)

Refers to a configuration to use for configuring the circuit breaker.

onFallback

public CircuitBreakerDefinition onFallback()

The fallback route path to execute that does not go over the network.

This should be a static or cached result that can immediately be returned upon failure. If the fallback requires network connection then use onFallbackViaNetwork().

onFallbackViaNetwork

public CircuitBreakerDefinition onFallbackViaNetwork()

The fallback route path to execute that will go over the network.

If the fallback will go over the network it is another possible point of failure.
