我有这个配置能够连接到compose.io rabbitmq服务
public class MinimumClass<T extends Comparable<T>> {
public T minElement(MySet<T> mySet) {
return Collections.min(mySet.getSet());
}
}
然而，在运行程序时，我在这一行中收到错误
package com.gandalf.configuration;
import org.springframework.amqp.rabbit.connection.CachingConnectionFactory;
import org.springframework.amqp.rabbit.connection.ConnectionFactory;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.amqp.rabbit.config.SimpleRabbitListenerContainerFactory;
import org.springframework.amqp.rabbit.listener.SimpleMessageListenerContainer;
import org.springframework.amqp.rabbit.listener.adapter.MessageListenerAdapter;
import org.springframework.amqp.rabbit.core.RabbitTemplate;
import org.springframework.amqp.rabbit.core.RabbitAdmin;
import org.springframework.amqp.core.AmqpAdmin;
import org.springframework.amqp.core.Queue;
import org.springframework.amqp.rabbit.connection.RabbitConnectionFactoryBean;
@Configuration
public class SpringAmqpConfiguration {
@Bean
public ConnectionFactory connectionFactory() {
CachingConnectionFactory connectionFactory = new CachingConnectionFactory();
connectionFactory.setAddresses("portal274-33.***,....");
connectionFactory.setUsername("amqpuser");
connectionFactory.setPassword("muggledone");
connectionFactory.setUseSsl(true);
return connectionFactory;
}
@Bean
public SimpleRabbitListenerContainerFactory rabbitListenerContainerFactory() {
SimpleRabbitListenerContainerFactory factory = new SimpleRabbitListenerContainerFactory();
factory.setConnectionFactory(connectionFactory());
factory.setConcurrentConsumers(3);
//If you want a fixed number of consumers, omit the max.
factory.setMaxConcurrentConsumers(10);
return factory;
}
@Bean
public RabbitTemplate rabbitTemplate() {
RabbitTemplate template = new RabbitTemplate(connectionFactory());
return template;
}
}
这是我得到的错误
connectionFactory.setUseSsl(true);为什么找不到 Compilation failure
/SpringAmqpConfiguration.java:[24,26] cannot find symbol
[ERROR] symbol: method setUseSsl(boolean)
[ERROR] location: variable connectionFactory of type org.springframework.amqp.rabbit.connection.CachingConnectionFactory
？
答案 0 :(得分：1)
useSsl上没有属性CachingConnectionFactory;基础useSslProtocol上 一个com.rabbitmq.client.ConnectionFactory属性。
使用connectionFactory.getRabbitConnectionFactory().useSslProtocol()。
