Spring-boot Integrated Dubbo:spring-boot-dubbo-starter

Why do you write this gadget?

If you have used Spring-boot to provide Dubbo services, I believe there are a lot of "uncomfortable" places in use. Since spring boot is used, there is no XML configuration where annotations can be used, which is spring-boot-style. A joke, really means that spring-boot is suitable for some simple, independent services, a large system is not suitable for the use of spring-boot to develop. On the contrary, Spring-boot is suitable for simple service construction. Most of the methods on the Web use XML configuration, using @import annotations to introduce XML configuration.

How to use

1. For the consumer or provider of the service, use the Dubbo built-in annotation @service or @reference to declare
2. Configure the relevant parameters of Dubbo in Application.properties/yml, for example, the following is a simple consumer configuration

   dubbo:application:     name:lizo-Consumer registry:     Address:zookeeper://  localhost:12181

3. Use @enabledubbo (basepackages = "xxx.xxx.xxx") on the configuration class to turn on automatic configuration of Dubbo

After the above 3 steps, you can complete the configuration of the Dubbo, is not very spring-bootstyle

Dubbo-filter

Dubbo has many extensions, where filter is used to compare one more. But it's not convenient to use. It would be nice if you could simply declare a bean just like the spring boot definition of Spring MVC filter. Well, that's actually it.

    @Bean    providerfilter providerfilter () {        returnnew  providerfilter ();    }     Static class extends Abstractdubboproviderfiltersupport {        public Result Invoke ( invoker<?> Invoker , invocation invocation) {            System.out.println ("Providerfilter");             return Invoker.invoke (invocation);        }    }

More customized requirements, you can use Dubbo's @activate annotations to customize the filter, so you can

@Bean customfilter customfilter () {return NewCustomfilter (); } @Activate (Group=Constants.provider)Static classCustomfilterextendsAbstractdubbofiltersupport { PublicResult Invoke (invoker<?> Invoker, invocation invocation)throwsrpcexception {System.out.println ("ProviderFilter2"); returnInvoker.invoke (invocation); }         PublicFilter getdefaultextension () {return  This; }    }
