java - Bundle 正在等待命名空间处理程序 [http ://camel. apache.org/schema/blueprint]

Question

我写了一个简单的 apache camel 项目，最终将部署在 FUSE 容器中。现在，我只是想让一个基本的单元测试正常工作。我正在使用示例 here作为起点。

我已经编写了有效的单元测试，但是当我包含一个蓝图文件时，我在测试输出中得到以下条目:

Bundle TestMainRoute 正在等待命名空间处理程序 [http://camel.apache.org/schema/blueprint]


测试失败并显示以下堆栈跟踪:

我的 xml 非常简单:

<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>

代码如下:

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. 列表项

}

注意验证路由被我的主 Camel 上下文引用:

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");
}

我有其他单元测试和日志记录表明这部分工作正常。

我有同样的错误，但另一个设置然后@mdarwin，所以我也想与你分享我的解决方案。

我用 camel-archetype-blueprint 开始了一个项目，所以我的命名空间如下所示:

blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0"
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   xmlns:cm="http://aries.apache.org/blueprint/xmlns/blueprint-cm/v1.1.0"
   xsi:schemaLocation="
     http://www.osgi.org/xmlns/blueprint/v1.0.0 https://www.osgi.org/xmlns/blueprint/v1.0.0/blueprint.xsd
     http://camel.apache.org/schema/blueprint http://camel.apache.org/schema/blueprint/camel-blueprint.xsd
     http://aries.apache.org/blueprint/xmlns/blueprint-cm/v1.1.0 http://aries.apache.org/schemas/blueprint-cm/blueprint-cm-1.1.0.xsd">

一开始它是一个非常简单的蓝图，带有一个定时器和一个文件端点，所以这里的实现并不重要。我将我的包部署到 Karaf为此，我安装了 aries-blueprint 功能。

我错过了，我感到很惭愧，是安装camel ， 也。为此，我必须添加 repo 并安装它，你可以阅读 here :

feature:repo-add camel
feature:install camel

现在命名空间处理程序就在那里。

我认为这是显而易见的，但还是花了几分钟才弄明白。
