启动类
  • 该加载的配置文件都加载上，没什么好说的；
package com.debug.mooc.dubbo.two.server;

import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
//import org.springframework.boot.context.web.SpringBootServletInitializer; //1.x版本

import org.springframework.boot.web.servlet.support.SpringBootServletInitializer; //2.x版本

import org.springframework.context.annotation.ImportResource;

@SpringBootApplication
@ImportResource(value = {"classpath:spring/spring-jdbc.xml","classpath:spring/spring-dubbo.xml"})
@MapperScan(basePackages = "com.debug.mooc.dubbo.two.model.mapper")
public class BootMoreApplication extends SpringBootServletInitializer {

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
        return builder.sources(BootMoreApplication.class);
    }

    public static void main(String[] args) throws Exception {
        SpringApplication.run(BootMoreApplication.class, args);
    }

}
RPC 调用
  • 注入 IDubboItemService，这是服务提供者 dubboOne 的子模块 api 中暴露出来的接口；spring/spring-dubbo.xml 中将它置入 IOC 容器，id 为 dubboItemService，这才使得 @Autowired 得以成功；
  • 对消费者提供者 dubboOne 服务的调用，和调用本地方法是一样的；
package com.debug.mooc.dubbo.two.server.controller;

import com.debug.mooc.dubbo.one.api.response.BaseResponse;
import com.debug.mooc.dubbo.one.api.service.IDubboItemService;
import com.google.common.collect.Maps;

@RestController
public class ItemController {

    private static final Logger log= LoggerFactory.getLogger(ItemController.class);

    private static final String prefix = "item";

    @Autowired
    private IDubboItemService dubboItemService;

        //TODO:调用服务提供方dubboOne提供的列表查询功能
        try {
