Question

我需要使用Camel ActiveMQ进行一些自定义。这样我就可以读取数据并将其推送到队列中。我有一个xml文件。项目构建没问题。执行程序时，我收到xml错误。

代码

public static void main(String[] args) {
        ClassPathXmlApplicationContext app = new ClassPathXmlApplicationContext(
                "config/my.xml");
        System.out.println("reading done");
    }

my.xml

<?xml version="1.0"?>

Answer 1

尝试删除无关的命名空间作为起点。

将您的beans标记更改为

<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="
          http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
          http://camel.apache.org/schema/spring http://camel.apache.org/schema/spring/camel-spring.xsd">

Answer 2

再次详细说明@ user940782的评论，以免错过答案。

我使用嵌入式Activemq来部署基于Camel的应用程序。我的Activemq v5.10.1使用Camel v2.13.1 我的骆驼应用程序使用的是v2.16.0

根据评论，我将应用程序中的Camel版本更改为2.13.1 问题得到了解决。

使用Camel ActiveMQ时出现xml错误
