我在一个springboot应用程序中开发了两个camel路由。first route read xml消息使用jaxb进行转换，处理json数据并将其发送到endrouteuri。

from(strartingRouteUri)
        .id("startRoute")
        .autoStartup(autoStartup)
        .errorHandler(errorHandler())
        .transacted("PROPAGATION_MANDATORY")
            .unmarshal(getJaxB())
            .convertBodyTo(SomeModel.class)
            .setExchangePattern(ExchangePattern.InOnly)
            .bean(modelMapper)
            .bean(processingService, "process")
            .marshal(createGsonDataFormat())
            .multicast()
                .to(endRouteUri).id(endRouteQueueName)
            .end()
        .end()
    .end();

从endrouteuri读取的第二条路径

from(endRouteUri)
        .id("secondRoute")
        .autoStartup(autoStartup)
        .onException(Exception.class)
            .id("errorHandler")
            .log( LoggingLevel.INFO,"${exception.stacktrace}")
        .end()
        .transacted("PROPAGATION_MANDATORY")
            .unmarshal(createGsonDataFormat())
            .setExchangePattern(ExchangePattern.InOnly)
            .bean("mapper", "mapToModel")
            .bean( "processor")
        .end()
    .end();

问题发生在第二个路由中，当它尝试从endrouteuri读取时，下面是堆栈跟踪

[org.apache.camel.RuntimeCamelException - org.springframework.transaction.IllegalTransactionStateException: No existing transaction found for transaction marked with propagation 'mandatory']
org.apache.camel.RuntimeCamelException: org.springframework.transaction.IllegalTransactionStateException: No existing transaction found for transaction marked with propagation 'mandatory'

我认为这是造成传播的问题，在这两个路线，我应该如何定义这一点？我需要对两个路由分别实现错误处理和回滚策略
