Spring与JavaDSL集成中的Bean和方法名与lambda
Spring与JavaDSL集成中的Bean和方法名与lambda,java,spring,spring-integration,dsl,Java,Spring,Spring Integration,Dsl,Spring Integration Java Dsl中有没有一种方法可以做到这一点: @Bean IntegrationFlow serviceFlow() { return IntegrationFlows .from("inputChannel") .handle(File.class, (p,h) -> someService.someMethod(p)) .channel("someChannel") .ge
Spring Integration Java Dsl中有没有一种方法可以做到这一点:
@Bean
IntegrationFlow serviceFlow() {
return IntegrationFlows
.from("inputChannel")
.handle(File.class, (p,h) -> someService.someMethod(p))
.channel("someChannel")
.get();
}
表现如下:
@Bean
IntegrationFlow serviceFlow() {
return IntegrationFlows
.from("inputChannel")
.handle("someService","someMethod")
.channel("someChannel")
.get();
}
当涉及到异常处理时
第一个版本抛出:

如果“行为像”的意思是将服务中的错误
异常作为第一个原因
,那么我们可以考虑从堆栈跟踪中删除调用目标异常
。这将使基础异常成为MessageHandlingException
的原因
如果您的意思是使堆栈跟踪完全相同,则不
如果您指的是前者,那么请打开一个针对JavaDSL
