Java 如何在Apache Camel中测试多个RouteBuilder

我想在单个单元测试中测试多个camel-RouteBuilder 我所拥有的：

更改状态的自定义camel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RouteBuilder：第一个将消息从“direct:start”路由到“direct:endroute1”，第二个从“direct:endroute1”拾取消息，并将消息路由到某个地方“mock:endroute2”

为单个管线生成器编写单元测试非常简单：

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");
           }
     };
 }
}

---

我真正想做的是以某种方式覆盖

CamelTestSupport.createRouteBuilder

，它将测试从

direct:start

到

mock:endroute2

的整个消息处理链。因此，

state.getState（）

应该是10

您可以使用

context.addRoutes（RouteBuilder）

API将多个RouteBuilder添加到上下文中

有关示例，请参见此单元测试：

您可以使用一个RouteBuilder替换多个其他RouteBuilder的路由。

尝试重写方法：

protected RouteBuilder[] createRouteBuilders() {...}

来自CamelTestSupport。它从2.17版开始提供

protected RouteBuilder[] createRouteBuilders() {...}
