当activemq连接丢失时，Spring Context关闭骆驼路由 [英] Spring Context shutting down camel routes when activemq connection is lost

问题描述

我有一个使用 spring-boot、Apache Camel 和 active MQ 的应用程序.骆驼路由是 activeMQ 队列轮询路由.

I have an application using spring-boot, Apache Camel and active MQ. The camel routes are activeMQ queue polling routes.

这是骆驼上下文.xml

This is the camel-context.xml

<?xml version="1.0" encoding="UTF-8"?>
<!-- Configures the Camel Context-->

Spring Boot 类

Spring boot class

package com.fileSupport.app;

import org.springframework.boot.SpringApplication;

public final class FileSupportMain {

    public static void main(final String[] args) {
        SpringApplication app = new SpringApplication(FileArchiveSpringBootApplication.class);
        app.setWebEnvironment(false);
        app.run(args);
    }

    private FileSupportMain() {
    }
}

Spring Boot 主类

Spring boot main class

package com.fileSupport.app;

import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.context.properties.EnableConfigurationProperties;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.ImportResource;

@ImportResource({"classpath:/META-INF/spring/camel-context.xml"})
@EnableConfigurationProperties

@SpringBootApplication
public  class FileSupportSpringBootApplication {
}



package com.fileSupport.app.routes;
import org.apache.camel.Exchange;
import org.apache.camel.LoggingLevel;
import org.apache.camel.builder.RouteBuilder;
import org.apache.camel.component.jackson.JacksonDataFormat;
import org.apache.camel.model.dataformat.JsonLibrary;
import org.springframework.stereotype.Component;

骆驼路线:

/**
 * ActiveMQ queue is watched by
 * this route which then performs content based
 * routing on the messages using XPath.
 */

@Component
public final class ConsumeActiveMQmessages extends RouteBuilder {

    @Override
    public void configure() throws Exception {


         from("activemq:queue:" + Variables.RECEIVE_QUEUE1)
             .routeId("queueRoute")

             .log(LoggingLevel.INFO, "Body: $simple{body}")
             .to("activemq:queue:" + Variables.RECEIVE_QUEUE2);

         from("activemq:queue:" + Variables.RECEIVE_QUEUE2)
         .to("direct:callback");

         from("direct:callback")

         .log(LoggingLevel.INFO, "body: $simple{body}")

         .end();

    }
}

推荐答案

如果你没有使用 spring-boot-starter-web 你应该打开 Camel 运行控制器选项.

If you are not using spring-boot-starter-web you should turn on the Camel run controller option.

查看该选项的文档:https://github.com/apache/camel/blob/master/components/camel-spring-boot/src/main/java/org/apache/camel/spring/boot/CamelConfigurationProperties.java#L124

您只需使用普通的 Spring Boot 配置样式进行配置即可.

You just configure this using normal spring boot configuration style.
