这次要说的是springboot整合activemq，对于消息队列小伙伴们有怎样的理解呢?下面来看看springboot如何集成activemq吧。
首先创建一个springboot项目，结构如下：
Pom文件
<?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.zhisheng</groupId> <artifactId>activemq</artifactId> <version>0.0.1-SNAPSHOT</version> <packaging>jar</packaging> <name>activemq</name> <description>Demo project for Spring Boot ActiveMQ</description> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>1.5.9.RELEASE</version> <relativePath/> <!-- lookup parent from repository --> </parent> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding> <java.version>1.8</java.version> </properties> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-activemq</artifactId> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> </plugins> </build> </project>
application.properties配置文件
spring.activemq.broker - url = tcp: //localhost:61616 spring.activemq.user = admin spring.activemq.password = admin
发送消息类
package com.zhisheng.activemq.client;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.jms.core.JmsTemplate;
import org.springframework.stereotype.Component;
@Component
public class ActiveMQClient
{
@Autowired
private JmsTemplate jmsTemplate;
public void send(String message)
{
jmsTemplate.convertAndSend("zhisheng", message);
}
}消息接收类
package com.zhisheng.activemq.server;
import org.springframework.jms.annotation.JmsListener;
import org.springframework.stereotype.Component;
@Component
public class ActiveMQServer
{
@JmsListener(destination = "zhisheng")
public void receive(String message)
{
System.out.println("收到的 message 是：" + message);
}
}PS：这个队列是不需要我们提前定义好的，它和 RabbitMQ 不一样，它会在我们需要的时候动态的创建。
下面可以开始运行
package com.zhisheng.activemq;
import com.zhisheng.activemq.client.ActiveMQClient;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.util.StopWatch;
import javax.annotation.PostConstruct;
@SpringBootApplication
public class ActivemqApplication
{
@Autowired
ActiveMQClient client;
@PostConstruct
public void init()
{
StopWatch stopWatch = new StopWatch();
stopWatch.start();
for (int i = 0; i < 10000; i++)
{
client.send("发送消息----zhisheng-----");
}
stopWatch.stop();
System.out.println("发送消息耗时: " + stopWatch.getTotalTimeMillis());
}
public static void main(String[] args)
{
SpringApplication.run(ActivemqApplication.class, args);
}
}这样就全部集成成功了。
以上就是关于springboot整合activemq的所有内容，经历了这么多，相信对于java项目中常见问题你已经有了自己独特的解决方法，还想了解更多的话，就来关注我们吧。
