对service-activator
使用基于XML的配置时,您可以排除method
,如下所示:
<service-activator input-channel="incomingCustomerChannel" output-channel="outgoingCustomerChannel" ref="customerService" />
这将导致SI框架根据有效负载在customerService
中选择目标方法。如何使用DSL和Java配置实现相同的功能?
目前我有以下内容:
@Bean
public IntegrationFlow customerRequestFlow(ConnectionFactory connectionFactory) {
return IntegrationFlows.from((MessagingGateways g) -> g.jms(connectionFactory)
.correlationKey("JmsCorrelationID")
.destination("customer_incoming.queue"))
.handle("customerService", "addCustomer")
.get();
}
服务激活器定义为:
@Component
public class customerService {
@ServiceActivator
public AddCustomerResponse addCustomer(AddCustomerRequest addCustomerRequest) {
// add customer
}
}
我已将激活器扩展为添加deleteCustomer
方法,如下所示:
@Component
public class customerService {
@ServiceActivator
public AddCustomerResponse addCustomer(AddCustomerRequest request) {
// add customer
}
@ServiceActivator
public DeleteCustomerResponse deleteCustomer(DeleteCustomerRequest request) {
// delete customer
}
}
我不能简单地从, "addCustomer"
移除.handle("customerService", "addCustomer")
,因为methodName
是强制性的。是否有可能在Java config / DSL中实现这一点?
答案 0 :(得分:3)
您可以使用.handle()
使用null
作为方法名称:
.handle("customerService", "addCustomer")
或者从version 1.1开始,您可以使用该方法的新版本:
@Autowired
private CustomerService customerService;
....
.handle(this.customerService)
这两种变体与ref
的{{1}}完全相同。
