基于SpringBoot中activeMq的JmsTemplate的實(shí)例

更新時(shí)間：2021年07月31日 09:51:50 作者：xiaoluo5238

這篇文章主要介紹了基于SpringBoot中activeMq的JmsTemplate的實(shí)例問(wèn)題，具有很好的參考價(jià)值，希望對(duì)大家有所幫助。如有錯(cuò)誤或未考慮完全的地方，望不吝賜教

SpringBoot 中使用activeMq的步驟：

1、pom中引入jar包：

  <dependency>
   <groupId>org.springframework.boot</groupId>
   <artifactId>spring-boot-starter-web</artifactId>
  </dependency>
  <dependency>
   <groupId>org.springframework.boot</groupId>
   <artifactId>spring-boot-starter-activemq</artifactId>
  </dependency>
  <dependency>
  <groupId>org.apache.activemq</groupId>
  <artifactId>activemq-pool</artifactId>
  <!-- <version>5.7.0</version> -->
  </dependency>

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 中添加對(duì)應(yīng)的bean生成規(guī)則

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、發(fā)送消息

package com.telligen.ascertain.approve.common.util.network;
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("發(fā)送 消息到消息隊(duì)列");
        jmsMessagingTemplate.convertAndSend(destinationName,message);
    }
}

遇到的問(wèn)題：

jmsMessagingTemplate 注入不成功，spring初始化錯(cuò)誤，異常如下，只要按照步驟三就可以了：

Springboot整合activemq時(shí)報(bào)jmsMessagingTemplate未加載錯(cuò)誤

錯(cuò)誤現(xiàn)象

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

網(wǎng)上解決方案

網(wǎng)上最多的方案是：application.properties中配置項(xiàng)的行尾有空格。檢查沒(méi)有，排除了這種可能。

第二種解決方案是：按如下方式將配置spring.activemq.pool.enabled改為false

spring.activemq.pool.enabled=false

啟動(dòng)springboot是不報(bào)錯(cuò)了，但是要發(fā)的消息也沒(méi)進(jìn)隊(duì)列。至于為什么就不報(bào)錯(cuò)了，還沒(méi)搞明白。如有高人請(qǐng)指點(diǎn)一二。

解決方案

查看ActiveMQConnectionFactoryConfiguration類,自動(dòng)配置發(fā)現(xiàn)需要引入下面這個(gè)依賴：

 <dependency> 
        <groupId>org.messaginghub</groupId>
        <artifactId>pooled-jms</artifactId>
        <version>1.0.3</version>
 </dependency>

將依賴引入pom，再啟動(dòng)springboot，搞定！

以上為個(gè)人經(jīng)驗(yàn)，希望能給大家一個(gè)參考，也希望大家多多支持腳本之家。
