Question

问题：

Red Hat Fuse快速入门应用程序“ 基于内容的路由器-Java DSL ”模板不起作用... -即，在构建，运行和部署（到“ Red Hat Fuse 7.1”）中时，永远不会创建“ work”文件夹。

这是Java代码...

package com.mycompany.camel;

import org.apache.camel.builder.RouteBuilder;

public class CamelRoute extends RouteBuilder {

    @Override
    public void configure() throws Exception {

        from("file:work/cbr/input")  //<== "work" folder not created...
            .log("Receiving order ${file:name}")
            .choice()
                .when().xpath("//order/customer/country[text() = 'UK']")
                    .log("Sending order ${file:name} to the UK")
                    .to("file:work/cbr/output/uk")
                .when().xpath("//order/customer/country[text() = 'US']")
                    .log("Sending order ${file:name} to the US")
                    .to("file:work/cbr/output/us")
                .otherwise()
                    .log("Sending order ${file:name} to another country")
                    .to("file:work/cbr/output/others")
            .log("Done processing ${file:name}");
    }

}

请注意，<<>基于内容的路由器-蓝图DSL ” 可以正常工作（即，它使用blueprint.xml文件定义路由，而不是Java代码）。< / p>

我正在使用“ Red Hat Developer Studio”中的“ quickstart”模板...

即

文件->新建->保险丝集成项目-> [创建项目名称]->选择“独立”平台，选择“卡拉夫/卡拉夫保险丝”->在“初学者”下选择“基于内容”路由器-Java DSL“->完成->等等.....

构建和热部署... Java DSL快速启动项目启动并运行-但是，它在创建父“工作”文件夹（几乎没有其他子文件夹）之前就停止了。...

关于模板项目和/或配置可能缺少什么的任何提示或指针吗？

奇思妙想：Java DSL是否在支持Spring DSL和/或Blueprint DSL方面走得那么远？...
（我曾将Java DSL与旧的Jboss Fuse 6.3一起使用，并且喜欢它...-希望再次使用它）

感谢您的帮助！：-）

Answer 1

我执行了以下步骤以使其能够与Fuse运行时一起使用：

创建一个新的保险丝集成项目-独立，Karaf / Karaf上的保险丝，CBR-Java DSL
创建一个新文件夹和文件“ src / main / resources / OSGI-INF / blueprint / blueprint.xml
blueprint.xml文件内容：

<?xml version="1.0" encoding="UTF-8"?> <blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 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"> <bean class="com.mycompany.camel.CamelRoute" id="myRouteBuilder"/> <camelContext id="cbr-example-context" xmlns="http://camel.apache.org/schema/blueprint"> <routeBuilder ref="myRouteBuilder"/> </camelContext> </blueprint>

通过Red Hat Developer Studio中的服务器视图部署项目

由于该文件位于我们JAR内的OSGI-INF / blueprint目录中，因此一旦安装了该软件包，它将自动将其激活。这是可能的，因为Red Hat Fuse将Apache Karaf与Blueprint部署程序结合使用-请参见Deploying into Apache Karaf - OSGi Services

无论如何，提供的模板应该是开箱即用的。因此，我为保险丝工具的开发人员提出了一个问题-https://issues.jboss.org/browse/FUSETOOLS-3178

Answer 2

检查C：\的文件夹权限，并如下所述使用uri：

from（“ file：// C：/ AAAInput /？autoCreate = true＆noop = true”）

Answer 3

好像您的路线根本没有开始。尝试使用直接引用来路由生成器，而不是像这样进行程序包扫描：

<camel:camelContext id="aaa.bbb.ccc.jar" xmlns="http://camel.apache.org/schema/blueprint">
    <camel:routeBuilder ref="routeBuilder"/>
</camel:camelContext>
<bean id="routeBuilder" class="aaa.bbb.ccc.jar.CamelRoute" />

Red Hat Fuse快速入门应用程序“基于内容的路由器-Java DSL”无法工作...-即，“ work”文件夹未创建...出了什么问题？
