为了迎合Spring的所有配置方式，增加了无XML配置实现，在此不对两种方式的优劣做比较，请根据项目的使用习惯做出合理选择。
实现Spring的JavaConfig配置方式，使用 Main.main(args) (需传参javaconfig设置使用JavaConfigContainer) 启动时可直接扫描 dubbo.spring.javaconfig包下的所有的Spring配置类
使用示例在dubbo-demo/dubbo-demo-consumer模块中，相关配置方式参考 注解配置
dubbo-demo-consumer/../DubboDemoConsumerConfig 等同于 dubbo-demo-consumer/../dubbo-demo-consumer.xmldubbo-demo-consumer/../DubboDemoActionConfig 等同于 dubbo-demo-consumer/../dubbo-demo-action.xmldubbo-demo-consumer/../DemoJavaConfigAction 等同于 dubbo-demo-consumer/../DemoActiondubbo-demo-consumer/../DemoJavaConfigConsumer 以JavaConfig方式启动示例程序将XML配置方式转换为JavaConfig配置，demo中未涉及到的配置类，请参照 API配置 实现
@Configuration public class DubboDemoConsumerConfig { public static final String APPLICATION_NAME = "consumer-of-helloworld-app"; public static final String REGISTRY_ADDRESS = "zookeeper://127.0.0.1:2181"; public static final String ANNOTATION_PACKAGE = "com.alibaba.dubbo.demo.consumer"; @Bean public ApplicationConfig applicationConfig() { ApplicationConfig applicationConfig = new ApplicationConfig(); applicationConfig.setName(APPLICATION_NAME); return applicationConfig; } @Bean public RegistryConfig registryConfig() { RegistryConfig registryConfig = new RegistryConfig(); registryConfig.setAddress(REGISTRY_ADDRESS); return registryConfig; } @Bean public AnnotationBean annotationBean() { AnnotationBean annotationBean = new AnnotationBean(); annotationBean.setPackage(ANNOTATION_PACKAGE); return annotationBean; } }
