Question

我只是从Camel 2.12升级到2.19.1并遇到我的#include <assert.h> #include <stdio.h> #define ASSERT(condition,...) assert( \ condition|| \ (fprintf(stderr,__VA_ARGS__)&&fprintf(stderr," at %s:%d\n",__FILE__,__LINE__)) \ );表达式问题：

wireTap

此代码在版本2.15之前正常工作，但是在Camel调用from("direct:start") .wireTap("bean:myWireTapBean") .to("bean:doSomething");上从2.16开始工作，并尝试将myWireTapBean结果解释为要调用的动态端点URI并产生此异常：

void

作为一种解决方法，我可以像这样定义路线：

Stacktrace: org.apache.camel.NoTypeConversionAvailableException: No type converter available to convert from type: null to the required type: 
java.lang.String with value null

但from("direct:start") .wireTap("bean:myWireTapBean").ignoreInvalidEndpoint() .to("bean:doSomething");对我来说很奇怪，因为ignoreInvalidEndpoint()是有效的终点。

使用bean:myWireTapBean的推荐方法是什么？它不会将提供的bean解释为计算动态URI但使用bean作为端点的表达式？

Apache Camel（版本＆gt; = 2.16）：使用wireTap将消息路由到Spring bean
