Spring Boot ActiveMQ如何設(shè)置訪問密碼
Apache ActiveMQ是Apache出品,是最流行的,能力很強的開源消息總線。默認情況下,程序連接ActiveMQ是不需要密碼的,為了安裝起見,需要設(shè)置密碼,提高安全性。本文分享如何設(shè)置訪問ActiveMQ的賬號密碼。
小編使用的ActiveMQ版本是apache-activemq-5.15.13。
一、設(shè)置控制臺管理密碼
ActiveMQ使用的是jetty服務(wù)器,找到 ActiveMQ安裝目錄下的\conf\jetty.xml文件:
<bean id="adminSecurityConstraint" class="org.eclipse.jetty.util.security.Constraint"> <property name="name" value="BASIC" /> <property name="roles" value="admin" /> <!-- set authenticate=false to disable login --> <property name="authenticate" value="true" /> </bean>
注意:authenticate的屬性默認為"true",登錄管理界面時需要輸入賬戶和密碼;如果是“false”,需要改為"true"。
修改管理界面登錄時的用戶名和密碼,在conf/jetty-realm.properties文件中添加用戶

配置信息按順序解釋,分別是:用戶名、密碼、角色名
二、消息生產(chǎn)者和消費者密碼認證
在\conf\activemq.xml中broker 標簽最后添加生產(chǎn)者和消費者密碼認證信息:
<!-- destroy the spring context on shutdown to stop jetty -->
<shutdownHooks>
<bean xmlns="http://www.springframework.org/schema/beans" class="org.apache.activemq.hooks.SpringContextHook" />
</shutdownHooks>
<!-- add plugins -->
<plugins>
<simpleAuthenticationPlugin>
<users>
<authenticationUser username="${activemq.username}" password="${activemq.password}" groups="users,admins"/>
</users>
</simpleAuthenticationPlugin>
</plugins>
</broker>
activemq.username和activemq.password的值在文件credentials.properties中配置,見如下步驟。
設(shè)置用戶名密碼,文件在\conf\credentials.properties

三、Java端配置用戶名密碼
驗證代碼是在《【Spring Boot】ActiveMQ 發(fā)布/訂閱消息模式介紹》的基礎(chǔ)上做重構(gòu),除了新增類ActiveMQConfig之外,修改部分均用紅色字體標注。配置application.properties連接信息:
## URL of the ActiveMQ broker. Auto-generated by default. For instance `tcp://localhost:61616` # failover:(tcp://localhost:61616,tcp://localhost:61617) # tcp://localhost:61616 spring.activemq.broker-url=tcp://localhost:61616 spring.activemq.in-memory=true spring.activemq.pool.enabled=false #默認值false,表示point to point(點到點)模式,true時代表發(fā)布訂閱模式,需要手動開啟 spring.jms.pub-sub-domain=true spring.activemq.user=wiener spring.activemq.password=wiener1237
在項目中配置 ActiveMQ連接屬性,新增ActiveMQConfig類:
import org.apache.activemq.ActiveMQConnectionFactory;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.jms.config.DefaultJmsListenerContainerFactory;
import org.springframework.jms.config.JmsListenerContainerFactory;
/**
* 配置 ActiveMQ
*
* @author east7
* @date 2020/6/23 11:27
*/
@Configuration
public class ActiveMQConfig {
@Value("${spring.activemq.user}")
private String usrName;
@Value("${spring.activemq.password}")
private String password;
@Value("${spring.activemq.broker-url}")
private String brokerUrl;
@Bean
public ActiveMQConnectionFactory connectionFactory() {
System.out.println("password =========== " + password);
return new ActiveMQConnectionFactory(usrName, password, brokerUrl);
}
/**
* 設(shè)置點對點模式,和下面的發(fā)布訂閱模式二選一即可
* @param connectionFactory
* @return
*/
@Bean
public JmsListenerContainerFactory<?> jmsListenerContainerQueue(ActiveMQConnectionFactory connectionFactory){
DefaultJmsListenerContainerFactory bean = new DefaultJmsListenerContainerFactory();
bean.setConnectionFactory(connectionFactory);
return bean;
}
@Bean
public JmsListenerContainerFactory<?> jmsListenerContainerTopic(ActiveMQConnectionFactory connectionFactory){
//設(shè)置為發(fā)布訂閱模式, 默認情況下使用生產(chǎn)消費者方式
DefaultJmsListenerContainerFactory bean = new DefaultJmsListenerContainerFactory();
bean.setPubSubDomain(true);
bean.setConnectionFactory(connectionFactory);
return bean;
}
}
bean.setPubSubDomain(true)配置會覆蓋properties文件中spring.jms.pub-sub-domain的屬性值,故可以在properties不設(shè)置spring.jms.pub-sub-domain屬性。另外,這種配置方式可以在系統(tǒng)中同時使用點對點和發(fā)布/訂閱兩種消息模式。修改訂閱者:
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.jms.annotation.JmsListener;
import org.springframework.stereotype.Component;
import javax.jms.JMSException;
/**
* 消費者
*/
@Component
public class Subscriber1 {
private static Logger logger = LoggerFactory.getLogger(Subscriber1.class);
/**
* 訂閱 topicListener1,僅僅加入containerFactory即可
*
* @param text
* @throws JMSException
*/
@JmsListener(destination = "topicListener1", containerFactory = "jmsListenerContainerTopic")
public void subscriber(String text) {
logger.info("Subscriber1 收到的報文:{}", text);
}
}
containerFactory 的值 "jmsListenerContainerTopic" 會自動匹配到ActiveMQConfig中的函數(shù)JmsListenerContainerFactory<?> jmsListenerContainerTopic(ActiveMQConnectionFactory connectionFactory)。 Subscriber2同樣修改即可,代碼省略。如果containerFactory 的值設(shè)置為jmsListenerContainerQueue,則開啟了點到點消息模式。
測試函數(shù)還可以使用topicTest()。下面提供一個新的測試途徑——在controller中測試。新增方法
@Autowired
private Publisher publisher;
@GetMapping("/sendTopicMsg")
public String sendTopicMsg(String msg) {
// 指定消息發(fā)送的目的地及內(nèi)容
Destination destination = new ActiveMQTopic("topicListener2");
for (int i = 0; i < 8; i++) {
publisher.publish(destination, msg + i);
}
return msg + " 發(fā)送完畢";
}
執(zhí)行結(jié)果省略。
