Apache Camel Context删除路由定义方法

Question

As part of my project requirement, I was going through the Apache Camel Docs for removing Routes from the camel context before updating it.

Here I am confused with removeRouteDefinition which removes a route definition from the CamelContext - stopping any previously running routes and removeRoute , stopRoute which does the same work as former.

What exactly is the difference between these methods?

Answer 1

The main difference is, that CamelContext#removeRouteDefinition stops gracefully route, and then removes it from Context .

The method CamelContext#removeRoute can remove only stopped route. If you try to remove running route, the method returns false and nothing happens.

So these two snippets are equivalents:

removeRouteDefinition

getContext().removeRouteDefinition(getContext().getRouteDefinition("routeId"));

removeRoute

getContext().stopRoute("routeId");
getContext().removeRoute("routeId");

Answer 2

As you can see from the documentation

void removeRouteDefinition(RouteDefinition routeDefinition)

takes a RouteDefinition object as the argument. Where as

boolean removeRoute(String routeId) throws Exception

takes a routeId.

Also another important thing is removeRouteDefinition is deprecated.
