Red Hat Fuse Quickstart 应用程序 "Content Based Router - Java DSL" 未创建 "work" 文件夹

Question

问题

Red Hat Fuse Quickstart 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"）时，永远不会创建 "work" 文件夹。

这里是 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”确实工作（即，它使用 blueprint.xml 文件来定义路线，而不是 Java 代码）。

我正在使用 "Red Hat Developer Studio" 中的 "quickstart" 模板。

即File-->New-->Fuse Integration Project-->[create project name]-->选择"Standalone"平台，选择"Karaf/Fuse on Karaf"-->在"Beginner"下选择"Content Based Router - Java DSL" --> 完成 --> 等等

已构建并热部署。 Java DSL 快速启动项目启动并运行s - 但是，它没有创建父 "work" 文件夹（更不用说其他子文件夹）了。

模板项目 and/or 配置中可能缺少什么？

我想知道：Java DSL 是否会被 Spring DSL and/or 蓝图 DSL 所取代？（我曾将 Java DSL 与旧的 Jboss Fuse 6.3 一起使用并且喜欢它）。

值得一提的是pom.xml:

jdk1.8.0_121

C:\apache-maven-3.6.0

Using Quickstart projects are referred to in Red Hat Fuse Tooling User Guide - PDF

Answer 1

检查 C:\ 的文件夹权限并使用如下所述的 uri：

从("file://C:/AAAInput/?autoCreate=true&noop=true")

Answer 2

看起来你的路线根本没有开始。尝试使用直接引用来路由构建器而不是像这样的包扫描：

<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" />

Answer 3

我执行了以下步骤以使其与 Fuse 运行时一起工作：

创建一个新的 Fuse 集成项目 - Standalone，Karaf / Fuse on Karaf，CBR - Java DSL
新建文件夹和文件“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>

在 Red Hat Developer Studio

Servers

因为该文件位于我们 JAR 中的 OSGI-INF/blueprint 目录中，所以它会在安装包后立即自动激活。这是可能的，因为 Red Hat Fuse 将 Apache Karaf 与 Blueprint 部署器结合使用 - 请参阅 Deploying into Apache Karaf - OSGi Services

无论如何，提供的模板应该开箱即用。因此，我向 Fuse Tooling 的开发人员提出了一个问题 - https://issues.jboss.org/browse/FUSETOOLS-3178
