如何在Apache Camel中测试多路由生成器

Question

我想在一个单元中测试多个camel RouteBuilder，我有：

更改状态的自定义骆驼处理器

public class MyProcessor implements Processor {
   MyState state;
   public MyProcessor(MyState state) {this.state = state;}

   @Override
   public void process(Exchange exchange) throws Exception {
   state.setState(state.getState() + 5);
   }}

两个简单的路由构建器：第一个路由消息从“direct：start”路由到“direct：endroute1”；第二个从“direct：endroute1”拾取消息并路由到“mock:endroute2”

public class MyRouteBuilder1 extends RouteBuilder {
    MyState state;
    public MyRouteBuilder1(MyState state) {this.state = state;}

    @Override
    public void configure() throws Exception {
        from("direct:start").process(new MyProcessor(state)).to("direct:endroute1");
    }}

public class MyRouteBuilder2 extends RouteBuilder {
    MyState state;
    public MyRouteBuilder2(MyState state) {this.state = state;}

    @Override
    public void configure() throws Exception {
        from("direct:endroute1").process(new MyProcessor(state)).to("mock:endroute2");
    }}

public class MyTest extends CamelTestSupport {
    MyState state = new MyStateImpl();

    @EndpointInject(uri = "mock:result")
    protected MockEndpoint resultEndpoint;

    @Test
    public void testSingleRoute() throws Exception {
        resultEndpoint.expectedMessageCount(1);
        template.sendBody("direct:start", new Object());
        assertTrue(state.getState() == 5);
        resultEndpoint.assertIsSatisfied();
    }

    @Override
    protected RouteBuilder createRouteBuilder() {
     return new MyRouteBuilder1(state) {
            public void configure() throws Exception{
               super.configure();
               from("direct:endroute1").to("mock:result");
           }
     };
 }
}

您可以使用context.addroutes(RouteBuilder)API将多个RouteBuilder添加到上下文中

有关示例,请参阅此单元测试：
