AdviceWith Page edited by Claus Ibsen Changes (3) ... {snippet:id=e1|lang=java|url="" h3. Using AdviceWithRouteBuilder *Available as of Camel 2.7* At current time you cannot alter the route by adding or changing exiting nodes in the route path. In the future we may want to introduce a special {{AdviceRouteBuilder}} which has special builder methods for altering the route etc. The {{AdviceWithRouteBuilder}} is a specialized {{RouteBuilder}} which has additional methods for advising routes. For example this allows you to manipulate the advised route, such as replacing a node with some other nodes. The {{AdviceWithRouteBuilder}} offers the following extra methods || Method || Description || | mockEndpoints | TODO: see | | mockEndpoints(pattern) | TODO: see | | adviceById(pattern) | Is used to select node(s) matching by id's. See below for pattern matching. | | adviceByToString(pattern) | Is used to select nodes(s) matching by their {{toString}} representation. See below for pattern matching. | The {{pattern}} option is used for matching. It uses the same rules as the [Intercept], which is applied in the following order: * match exact * match by wildcard * match by regular _expression_ For example to match exact you can use {{adviceBy("foo")}} which will match only the id in the route which has the value {{"foo"}}. The wildcard is when the pattern ends with a {{*}} char, such as: {{adviceBy("foo*")}} which will match any id's starting with {{"foo"}}, such as {{foo, foobar, foobie}} and so forth. The regular _expression_ is more advanced and allows you to match multiple ids, such as {{adviceBy("(foo|bar)")}} which will match both {{"foo"}} and {{"bar"}}. Full Content AdviceWith Available as of Camel 2.1 AdviceWith is used for testing Camel routes where you can advice an existing route before its being tested. What adviceWith allows is to changes some factors on the route before the test is being run. At current time you can advice an existing route by adding Intercept, Exception Clause etc. which then will apply for the route being advice. For example in the route below we intercept sending a message to the mock:foo endpoint and detour the message. public void testAdvised() throws Exception { // advice the first route using the inlined route builder context.getRouteDefinitions().get(0).adviceWith(context, new RouteBuilder() { @Override public void configure() throws Exception { // intercept sending to mock:foo and do something else interceptSendToEndpoint("mock:foo") .skipSendToOriginalEndpoint() .to("log:foo") .to("mock:advised"); } }); getMockEndpoint("mock:foo").expectedMessageCount(0); getMockEndpoint("mock:advised").expectedMessageCount(1); getMockEndpoint("mock:result").expectedMessageCount(1); template.sendBody("direct:start", "Hello World"); assertMockEndpointsSatisfied(); } Using AdviceWithRouteBuilder Available as of Camel 2.7 The AdviceWithRouteBuilder is a specialized RouteBuilder which has additional methods for advising routes.
