SpringBoot Camel SendBody（）路由未发送

长孙雅志
2023-03-14

我正在尝试创建一个SpringBoot Camel应用程序（用于测试）。我已经配置了SpringBoot和camel-spring。它似乎在工作，但在将数据发送到activemq（通过SendBody）时却失败了。

ApplicationContext.xml

<?xml version="1.0" encoding="UTF-8"?>

<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">

<bean id="activemq" class="org.apache.activemq.camel.component.ActiveMQComponent">
    <property name="configuration" ref="jmsConfig"/>
</bean>

<bean id="jmsConnectionFactory" class="org.apache.activemq.ActiveMQConnectionFactory">
    <property name="brokerURL" value="failover:(tcp://localhost:61616)"/>
    <property name="useAsyncSend" value="true"/>
    <property name="watchTopicAdvisories" value="false"/>
</bean>

<bean id="pooledConnectionFactory" class="org.apache.activemq.pool.PooledConnectionFactory"
      init-method="start" destroy-method="stop">
    <property name="maxConnections" value="8" />
    <property name="connectionFactory" ref="jmsConnectionFactory" />
</bean>

<bean id="jmsTemplate" class="org.springframework.jms.core.JmsTemplate">
    <property name="connectionFactory" ref="pooledConnectionFactory" />
</bean>

<camelContext id="camelContext" xmlns="http://camel.apache.org/schema/spring" allowUseOriginalMessage="false">
    <jmxAgent id="agent" disabled="true"/>

    <route>
        <from uri="direct:a" />
        <to uri="activemq:queue:ingest.Queue" />
    </route>
</camelContext>

它在template.sendBody（）处失败的主应用程序

package com.sis.klaver;

import org.apache.camel.CamelContext;
import org.apache.camel.ProducerTemplate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.ApplicationContext;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;

@SpringBootApplication
public class MainApp {

public static void main(String[] args) {
    SpringApplication.run(MainApp.class, args);
}

@Autowired
private CamelContext camelContext;

@Bean
public String DoThis(ApplicationContext ctx) {
    ProducerTemplate template = camelContext.createProducerTemplate();
    template.sendBody("direct:a", "blah blah blah");

    return "one";
}
}

有人知道它为什么不起作用吗？对于我读过的文件来说，它应该能起作用。

直接路由：A未启动添加@importresource如下所示

@SpringBootApplication
@ImportResource("classpath:applicationContext.xml")
public class MainApp {

更新

如果可以的话，请删除@bean和parameter，并通过另一种方式调用DoThis，因为我认为xml导入要晚于带注释的config完成，并且DoThis中的发送者试图在使用者激活之前发送。

//@Bean
public String DoThis() {

template.sendBody("direct:a?block=true", "blah blah blah");

block:default=false，Camel 2.11.1:如果向没有活动使用者的直接endpoint发送消息，那么我们可以告诉生产者阻止并等待使用者活动。
