配置 Dubbo

修改 application.yml 配置文件

dubbo:
  application:
    id: gaming-server-web-admin
    name: gaming-server-web-admin
  registry:
    id: zookeeper
    address: zookeeper://192.168.75.132:2181?backup=192.168.75.132:2182,192.168.75.132:2183
  scan:
    base-packages: com.ooqiu.gaming.server.web.admin.controller

完整的 application.yml

使用 @Reference 注解注入服务提供者

package com.ooqiu.gaming.server.web.admin.controller;

import com.alibaba.dubbo.config.annotation.Reference;
import com.ooqiu.gaming.server.domain.Channel;
import com.ooqiu.gaming.server.service.admin.api.ChannelService;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import java.util.List;

@RestController
public class ChannelController {
    @Reference(version = "1.0.0")
    private ChannelService channelService;

    @RequestMapping(value = "hi")
    public String list() {
        List<Channel> channels = channelService.selectAll();
        System.out.println(channels);
        return "Hi";
    }
}
