【转】SpringBoot学习笔记(7) SpringBoot整合Dubbo(使用yml配置)

http://blog.csdn.net/a67474506/article/details/61640548

 

Dubbo是什么东西我这里就不详细介绍了,自己可以去谷歌

 

SpringBoot整合Dubbo的话我们首先要先对Dubbo的启动这块了解一哈

 

dubbo源码分析:http://blog.csdn.net/flashflight/article/details/44318447

 

Dubbo会注册各种解析器,因为我们这边不会在使用XML配置了,所以主要关注的地方就是这块

 

通过BeanDefinitionParser解析,然后注册到Ioc容器中,而这里我们通过SpringBoot的自动配置,读取yml配置生成SpringBean

 

基本上我们只有用到 registry,provider, protocol ,application这些

然后暴漏服务和引用服务 通过annotationBean这个东东


 

因为使用了yml或者properties的方式来配置dubbo,所以我们还需要dubbo的AnnotionBean类,来扫描指定包下面的类.

 

这里集成dubbo的时候和前面集成其他东西的是差不多的,不过在使用了AnnotionBean类的时候,因为AnnotionBean类实现了BeanFactoryPostProcessor接口.


 

这里还有一篇资料:

http://blog.csdn.net/u011686226/article/details/53841227

刚开始不知道的时候日志里面提示是这样的

[html] view plain copy
 
  1. @Bean method DubboAutoConfiguration.annotationBean is non-static and returns an object assignable to Spring's BeanFactoryPostProcessor interface.   
  2. This will result in a failure to process annotations such as @Autowired, @Resource and @PostConstruct within the method's declaring @Configuration class.  
  3.  Add the 'static' modifier to this method to avoid these container lifecycle issues; see @Bean javadoc for complete details.  


 

解决了这个问题之后,下面的就可以直接按照原先的步骤来搞

项目结构

 

分别启动dubbo-provider 和 dubbo-consume

我们可以再zookeeper的client里面看到相关信息

这个是服务提供者的信息

 

这个是服务消费者的信息

 

这个是访问结果
