尝试在 apache 骆驼中获取原始消息时发生异常

Question

我正在尝试在我的骆驼异常处理程序中获取原始消息。我正在尝试致电

exchange.getUnitOfWork().getOriginalInMessage()

但出现以下异常

java.lang.IllegalStateException: AllowUseOriginalMessage is disabled. Cannot access the original message.
    at org.apache.camel.impl.engine.DefaultUnitOfWork.getOriginalInMessage(DefaultUnitOfWork.java:307)

如何启用

AllowUseOriginalMessage

功能？

Answer 1

这可以通过

CamelContext.setAllowUseOriginalMessage(Boolean)

启用

例如：

@Bean
public CamelContext camelContext(ApplicationContext applicationContext, List<RoutesBuilder> routeBuilders) throws Exception {
    SpringCamelContext context = new SpringCamelContext(applicationContext);
    context.setAllowUseOriginalMessage(true);
    for (RoutesBuilder routeBuilder : routeBuilders) {
        context.addRoutes(routeBuilder);
    }   
    ...
    return context;
}

参见 RuntimeConfiguration.setAllowUseOriginalMessage(java.lang.Boolean)
