dubbo设置自定义路由

1.新建路由工厂

import org.apache.dubbo.common.URL;
import org.apache.dubbo.common.extension.Activate;
import org.apache.dubbo.rpc.cluster.Router;
import org.apache.dubbo.rpc.cluster.RouterFactory;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

/**

 */
@Activate(order = 1)
public class EnvRouterFactory implements RouterFactory {

    private static final Logger LOGGER = LoggerFactory.getLogger(EnvRouterFactory.class);

    @Override
    public Router getRouter(URL url) {
        LOGGER.info("启动dubbo特性环境路由");
        return new EnvRouter();
    }
}

2. 新建路由

public class EnvRouter extends AbstractRouter {

    private static final Logger LOGGER = LoggerFactory.getLogger(EnvRouter.class);

    public EnvRouter() {
        this.priority = Integer.MAX_VALUE + 2;
    }

    @Override
    public <T> List<Invoker<T>> route(List<Invoker<T>> invokers, URL url, Invocation invocation)
            throws RpcException {
      //TODO 逻辑处理
        return invokers;
    }
}

3.在/resrouces/META-INF/dubbo/目录新建org.apache.dubbo.rpc.cluster.RouterFactory配置文件

envRouterFactory=com.weimai.envrouter.dubbo.router.EnvRouterFactory
