Class CommandGatewayFactoryBean<T>

java.lang.Object

org.axonframework.commandhandling.gateway.CommandGatewayFactoryBean<T>

Type Parameters:

T - The type of gateway to be created by this factory bean. Note that the correct interface must also be set using setGatewayInterface(Class). Failure to do so may result in class cast exceptions.

All Implemented Interfaces:

org.springframework.beans.factory.FactoryBean<T>, org.springframework.beans.factory.InitializingBean

public class CommandGatewayFactoryBean<T>
extends Object
implements org.springframework.beans.factory.FactoryBean<T>, org.springframework.beans.factory.InitializingBean

FactoryBean that creates a gateway instance for any given (compatible) interface. If no explicit interface is provided, the CommandGateway interface is assumed.

For details about the structure of compatible interfaces, see GatewayProxyFactory.

Method Detail

getObject

public T getObject()
            throws Exception

Specified by:

getObject in interface org.springframework.beans.factory.FactoryBean<T>

Throws:

Exception

getObjectType

public Class<?> getObjectType()

Specified by:

getObjectType in interface org.springframework.beans.factory.FactoryBean<T>

isSingleton

public boolean isSingleton()

Specified by:

isSingleton in interface org.springframework.beans.factory.FactoryBean<T>

afterPropertiesSet

public void afterPropertiesSet()
                        throws Exception

Specified by:

afterPropertiesSet in interface org.springframework.beans.factory.InitializingBean

Throws:

Exception

setCommandBus

public void setCommandBus(CommandBus commandBus)

Sets the command bus on which the Gateway must dispatch commands. This property is required.

Parameters:

commandBus - the command bus on which the Gateway must dispatch commands

setRetryScheduler

public void setRetryScheduler(RetryScheduler retryScheduler)

Sets the RetryScheduler that will be invoked when a command fails execution. If no scheduler is provided, commands will report the failure immediately.

Parameters:

retryScheduler - the RetryScheduler that will be invoked when a command fails execution

setGatewayInterface

public void setGatewayInterface(Class<T> gatewayInterface)

Sets the interface that describes the gateway instance to describe. If no interface is provided, it defaults to CommandGateway.

Parameters:

gatewayInterface - The interface describing the gateway

Throws:

IllegalArgumentException - if the given gatewayInterface is null or not an interface.

setCommandDispatchInterceptors

public void setCommandDispatchInterceptors(CommandDispatchInterceptor... commandDispatchInterceptors)

Sets the interceptors that should be invoked before a command is dispatched the the Command Bus.

Note that these interceptors will be specific to this Gateway instance. Messages dispatched through other gateways or directly to the command bus will not pass through these interceptors.

Parameters:

commandDispatchInterceptors - the interceptors that should be invoked before a command is dispatched the the Command Bus

setCommandDispatchInterceptors

public void setCommandDispatchInterceptors(List<CommandDispatchInterceptor> commandDispatchInterceptors)

Sets the interceptors that should be invoked before a command is dispatched the the Command Bus.

Note that these interceptors will be specific to this Gateway instance. Messages dispatched through other gateways or directly to the command bus will not pass through these interceptors.

Parameters:

commandDispatchInterceptors - the interceptors that should be invoked before a command is dispatched the the Command Bus
