@Bean
 @ConditionalOnMissingBean(value=com.google.common.eventbus.EventBus.class)
public com.google.common.eventbus.EventBus asyncEventBus()

注入一个guava异步消息总线

使用该异步消息总线的示例如下：

 @Component
 public class DemoEventBus {
        @Resource
        private EventBus asyncEventBus;
 
        @PostConstruct
        public void init() {
                asyncEventBus.register(this);
        }
 }
 
 

发送消息

 asyncEventBus.post("需要发送的数据");
 

接收消息

 @Subscribe
 public void recieve(Object data) {
        // 注意guava是根据入参的数据类型进行接收的
        // 发送的数据可以被多个接收者同时接收
 }
 

Returns:

guava异步消息总线

@PostConstruct
public void checkConfig()
