Mule 异常是否通过组件绑定传播?
使用下面的Mule配置和Java代码,我无法让Mule通过组件绑定传播异常。如何让远程服务抛出的异常传播到调用组件?Mule EE 3.2.2 谢谢 骡子配置Mule 异常是否通过组件绑定传播?,mule,Mule,使用下面的Mule配置和Java代码,我无法让Mule通过组件绑定传播异常。如何让远程服务抛出的异常传播到调用组件?Mule EE 3.2.2 谢谢 骡子配置 <mule ...> <flow name="Test"> <vm:inbound-endpoint path="Test" exchange-pattern="request-response" /> <component class="foo.Component">

异常不是通过消息交换作为“抛出的异常”传播的,而是作为飞行中消息上的异常有效负载传播的 因此,调用
vm://Interface.bar
的响应应该是一条消息,其中包含一个与您抛出的异常一起设置的异常负载。因为绑定将主有效负载绑定到接口,所以无法从组件访问它
一个选项是在接口.bar
流中添加一个响应转换器,它将异常负载(如果有)复制到主负载,并允许bar()返回对象(有时是字符串,有时是异常)。或者使用String并将返回的错误定义为String
