Bundle正在等待命名空間處理程序[http://camel.apache.org/schema/blueprint]

Question

我寫了一個簡單的apache camel項目，最終將其部署在FUSE容器中。目前，我只是試圖獲得基本的單元測試工作。我以示例here爲起點。

我已經寫單元測試它的工作，但是當我有一個藍圖文件，我得到測試輸出輸入以下內容：

Bundle TestMainRoute is waiting for namespace handlers [http://camel.apache.org/schema/blueprint]

並導致測試失敗與以下堆棧跟蹤：

我的XML是非常簡單的：

<blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0"> 
    <routeContext id="validationRoute" xmlns="http://camel.apache.org/schema/blueprint" > 

    <route id="validation"> 
     <from uri="direct:validation" /> 
     <log message="validating..." /> 
    </route> 
</routeContext> 

由於是代碼：

public class RouteTest extends CamelBlueprintTestSupport { 

    @Test 
    public void testValidationRoute() throws Exception { 
    DefaultExchange r1 = new DefaultExchange(context); 
    r1.getIn().setBody(""); 
    Exchange response1 = template.send("direct:validation", r1); 
    } 

    protected String getBlueprintDescriptor() { 
    return "OSGI-INF/blueprint/blueprint.xml"; 

1. 列表項

} }

NB驗證路由是由我的主要駱駝的上下文中引用：

public class IntegrationFramework extends RouteBuilder { 

public void configure() { 

    from("netty-http:http://localhost:8457/broker/router.jsp").convertBodyTo(String.class) 
    .log("http router "+simple("${body}").getText()) 
    .to("direct:validation"); 
} 

我有其他的單元測試和記錄，表明這部分工作。

Answer 1

原來，routeContext只存在於xml dsl的上下文中，並且不能從Java DSL引用。這在我看來是一個錯誤，因爲它限制了混合xml和java配置的靈活性。

通過將routeContext更改爲camelContext，解決了這個問題。

也看到這個問題：Camel: importing routeContext into an external camelContext
