【Spring Boot】ActiveMQ 设置访问密码
小編覺得挺不錯的,現在分享給大家,幫大家做個參考.
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，需要設置密碼，提高安全性。本文分享如何設置訪問ActiveMQ的賬號密碼。
小編使用的ActiveMQ版本是apache-activemq-5.15.13。
一、設置控制臺管理密碼
ActiveMQ使用的是jetty服務器，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

## --------------------------------------------------------------------------- # Defines users that can access the web (console, demo, etc.)
# username: password [,rolename ...]
# admin: admin, admin
# user: user, user
wiener: wiener1237, admin
配置信息按順序解釋，分別是：用戶名、密碼、角色名
二、消息生產者和消費者密碼認證
在\conf\activemq.xml中broker 標簽最后添加生產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。
設置用戶名密碼，文件在\conf\credentials.properties

## --------------------------------------------------------------------------- # Defines credentials that will be used by components (like web console) to access the broker # activemq.username=system
# activemq.password=manager
# guest.password=password activemq.username=wiener
activemq.password=wiener1237
guest.password=password
三、Java端配置用戶名密碼
驗證代碼是在《【Spring Boot】ActiveMQ 發布/訂閱消息模式介紹》的基礎上做重構，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);
} /**
* 設置點對點模式，和下面的發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){
//設置為發布訂閱模式, 默認情況下使用生產消費者方式
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不設置spring.jms.pub-sub-domain屬性。另外，這種配置方式可以在系統中同時使用點對點和發布/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JmsListenerContainerFactory<?> jmsListenerContainerTopic(ActiveMQConnectionFactory connectionFactory)。 Subscriber2同樣修改即可，代碼省略。如果containerFactory 的值設置為jmsListenerContainerQueue，則開啟了點到點消息模式。
測試函數還可以使用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) {
// 指定消息發送的目的地及內容
Destination destination = new ActiveMQTopic("topicListener2");
for (int i = 0; i < 8; i++) {
publisher.publish(destination, msg + i);
}
return msg + " 發送完畢";
}
執行結果省略。
