Camel - Passing specific parameters from routes to a generic bean method
提问by abbasdgr8
Let's say I have a Camel route that looks like this :
假设我有一条看起来像这样的骆驼路线：
from("direct:myRoute")
.setHeader("someHeader", simple("some header value"))
.beanRef("myBean", "beanMethod");
And I have a bean that I cannot changethat looks like this :
我有一个豆子cannot change，看起来像这样：
public class MyBean {
public void beanMethod(String headerExpected) {
// do something with the value here.
}
}
Basically, I want to pass the value of someHeaderfrom myRouteto beanMethodwithin MyBean.
基本上，我想传递的价值someHeader从myRoute到beanMethod内为myBean。
Knowing that beanMethod can accept a String, how can I pass the value of the header someHeaderfrom the route so that it is accepted as a String within beanMethod?
知道 beanMethod 可以接受 a String，我如何从路由中传递标题someHeader的值，以便它在beanMethod 中被接受为 String ？

You can pass parameters in the way you described like this:
您可以按照您描述的方式传递参数，如下所示：
from("direct:myRoute")
.setHeader("someHeader", simple("some header value"))
.to("bean:myBean?method=beanMethod(${header.someHeader})")
