spring javaconfig container

[majinkai]

1. 模块描述

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 bubbo.spring.javaconfig 包下的所有的Spring配置类

2. 使用示例

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

2.1 代码解释

• dubbo-demo-consumer/../DubboDemoConsumerConfig 等同于 dubbo-demo-consumer/../dubbo-demo-consumer.xml
• dubbo-demo-consumer/../DubboDemoActionConfig 等同于 dubbo-demo-consumer/../dubbo-demo-action.xml
• dubbo-demo-consumer/../DemoJavaConfigAction 等同于 dubbo-demo-consumer/../DemoAction
• dubbo-demo-consumer/../DemoJavaConfigConsumer 以JavaConfig方式启动示例程序

2.2 示例演示

1. 运行dubbo-demo-provider/../DemoProvider
2. 运行dubbo-demo-consumer/../DemoJavaConfigConsumer
3. 查看console输出

3. 去xml化配置

将xml配置方式转换为Java类配置，未涉及到的配置，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;
    }
}
