基于SpringBoot中activeMq的JmsTemplate的实例

基于SpringBoot中activeMq的JmsTemplate的实例

SpringBoot 中使用activeMq的步骤：

1、pom中引入jar包：

org.springframework.boot

spring-boot-starter-web

spring-boot-starter-activemq

org.apache.activemq

activemq-pool

2、spring boot配置文件中配置activeMq

spring.activemq.broker-url=tcp://localhost:61616

spring.activemq.user=admin

spring.activemq.password=admin

spring.activemq.in-memory=true

spring.activemq.pool.enabled=false

3、Application 中添加对应的bean生成规则

package com.telligen.ascertain;

import org.apache.activemq.ActiveMQConnectionFactory;

import org.springframework.boot.SpringApplication;

import org.springframework.boot.autoconfigure.SpringBootApplication;

import org.springframework.context.annotation.Bean;

import org.springframework.jms.core.JmsMessagingTemplate;

import org.springframework.jms.core.JmsTemplate;

import javax.jms.ConnectionFactory;

@SpringBootApplication

public class ApproveApplication {

public static void main(String[] args) {

SpringApplication.run(ApproveApplication.class, args);

}

@Bean

public ConnectionFactory connectionFactory(){

System.out.println("aaaaaaaaaaaaaaaaaaaaaa");

ActiveMQConnectionFactory connectionFactory = new ActiveMQConnectionFactory();

connectionFactory.setBrokerURL("tcp://localhost:61616");

connectionFactory.setUserName("admin");

connectionFactory.setPassword("admin");

return connectionFactory;

}

@Bean

public JmsTemplate genJmsTemplate(){

System.out.println("aaaaaaaaaaaaaaaaaaaaaabbbbbbbbb");

return new JmsTemplate(connectionFactory());

}

@Bean

public JmsMessagingTemplate jmsMessageTemplate(){

System.out.println("ccccccccccccc");

return new JmsMessagingTemplate(connectionFactory());

}

}

4、发送消息

package com.telligen.ascertain.approve.common.util-work;

import org.apache.log4j.Logger;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.context.annotation.Scope;

import org.springframework.jms.core.JmsMessagingTemplate;

import org.springframework.stereotype.Component;

@Component

@Scope("singleton")

public class ActiveMqUtil {

private Logger logger = Logger.getLogger(ActiveMqUtil.class);

@Autowired

private JmsMessagingTemplate jmsMessagingTemplate;

public void sendMsg(String destinationName ,String message){

logger.info("发送 消息到消息队列");

jmsMessagingTemplate.convertAndSend(destinationName,message);

}

}

遇到的问题：

jmsMessagingTemplate 注入不成功，spring初始化错误，异常如下，只要按照步骤三就可以了：

Springboot整合activemq时报jmsMessagingTemplate未加载错误

错误现象

Bean method ‘jmsMessagingTemplate' in ‘JmsAutoConfiguration.MessagingTemplateConfiguration' not loaded because Ancestor org.springframework.boot.autoconfigure.jms.JmsAutoConfiguration did not match

网上解决方案

网上最多的方案是：application.properties中配置项的行尾有空格。检查没有，排除了这种可能。

第二种解决方案是：按如下方式将配置spring.activemq.pool.enabled改为false

spring.activemq.pool.enabled=false

启动springboot是不报错了，但是要发的消息也没进队列。至于为什么就不报错了，还没搞明白。如有高人请指点一二。

解决方案

查看Ahttp://ctiveMQConnectionFactoryConfiguration类,自动配置发现需要引入下面这个依赖：

org.messaginghub

pooled-jms

1.0.3

将依赖引入pom，再启动springboot，搞定！
