使用Spring Boot 与Dubbo集成,这里我之前尝试了使用注解的方式,简单的使用注解注册服务其实是没有问题的,但是当你涉及到使用注解的时候在服务里面引用事务,注入其他对象的时候,会有一些问题。于是我就果断放弃了注解了,使用的是XML,这里可能介绍的是Dubbo,但是如果使用Dubbox的话,基本上是兼容的。接下来,将说说使用XML的方式与Spring Boot在一起开发。
1.创建工程在pom.xml中加入依赖
创建工程名为:
(1)springboot-dubbo-provide
(2)springboot-dubbo-api
(3)springboot-dubbo-consume
springboot-dubbo-api工程主要是放一些service接口,用于提供给消费者使用 。springboot-dubbo-provide工程用于提供服务。 springboot-dubbo-consume工程为消费者。在springboot-dubbo-provide工程中打开pom.xml加入以下依赖,完整代码如下:

注意:这里我发布的example服务是示例,具体的根据实际修改

#应用名称 dubbo.application.name=example-consume #注册中心类型 dubbo.registry.protocol=zookeeper #注册中心地址 dubbo.registry.address=127.0.0.1:2181 |
到这里基本上就已经可以了,不过测试类的代码我就不贴上来了。只要在API中定义接口实现即可。使用Spring Boot 与Dubbo集成的时候,需要注意的是,不要使用Spring Boot提供的devtools热启动,因为devtools提供了两个ClassLoader,加载策略问题导致出现错误,无法启动。如果开发中需要热加载,那么使用Spring 提供的springloaded。
