SpringBoot2.0之整合Dubbo

Dubbo支持协议

 Dubbo支持dubbo、rmi、hessian、http、webservice、thrift、redis等多种协议,但是Dubbo官网是推荐我们使用Dubbo协议的。

 

Spring Cloud 项目feign客户端 继承依赖方式实现重构项目

 

jar: 打成jar包

pom:依赖被被人继承的 公共依赖 字符模块

war:达成一个web项目 里面包含jar包、WEB-INF

 

toov5-dubbo-parent        pom

        toov5-public-api-service        pom    提供会员接口  jar类型   pom项目没有Java代码的哦

        toov5-api-member-service 

        toov5-api-member-service-impl  会员接口实现类(这个不是公开的) (点击parent创建的,需要引入 实现的interface )

   toov5-dubbo-order-web   jar(springboot)     订单项目 调用会员项目   ps:订单调用会员时候 引入公共接口  底层调用dubbo协议 帮助实现  *(dubbo原理  拿到类的class的地址信息,反射。)

 

 

parent引入共同依赖:

点击parent 创建 maven pom   :toov5-public-api-service (公共接口maven model)    点击 toov5-public-api-service  创建   toov5-api-member-service    jar  (写接口 interface) 

点击parent 创建 maven jar :  toov5-api-member-service-impl   并且 引入: toov5-api-member-service 的依赖 dependency

 

接口: 

package com.toov.api.member.service;

public interface MemberService {
   
    public String getUser();
    
}

实现类:

package com.toov.api.member.service.impl;

import com.alibaba.dubbo.config.annotation.Service;
import com.toov.api.member.service.MemberService;

@Service
public class MemberServiceImpl implements MemberService {

    public String getUser() {
        System.out.println("订单服务调用会员服务");
        return "订单服务调用会员服务成功";
    }
      
}

启动类:

package com.toov.api.member.service.impl;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

import com.alibaba.dubbo.config.spring.context.annotation.EnableDubbo;

@EnableDubbo
@SpringBootApplication
public class App {
  public static void main(String[] args) {
    SpringApplication.run(App.class, args);
}
}

yml:

server:
  port: 8080
dubbo:
  application:
    name: member
    #表示采用的dubbo协议
  protocol:
    name: dubbo
    #发布的端口号
    port: 20880 
  registry:
    address: zookeeper://192.168.91.5:2181

 

  

PS:如果需要写版本号的 springboot没有帮你整合  如果不需要写版本号  已经帮忙整合了

 

Dubbo发布时候 采用注解方式! 使用 @Service注解 进行发布服务

记得采用 Dubbo 而不是 spring 的注解!

区别:  spring 提供的 是注入到Spring容器中 dubbo是注册到注册中心去!

扫的实现类 注册到dubbo 注册中心中去

 

启动效果:

 

 点击parent 创建 toov5-dubbo-order-web  jar   然后引入接口依赖!

 

package toov5.order.controller;

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import com.alibaba.dubbo.config.annotation.Reference;
import com.toov.api.member.service.MemberService;

@RestController
public class OrderController {
    @Reference  //dubbo提供的  而不是@Autowired
    private MemberService memberService;
    @RequestMapping("/orde")
    public String orderToMember() {
        return memberService.getUser();
        
    }
    
}

启动类:

package toov5.order.controller;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

import com.alibaba.dubbo.config.spring.context.annotation.EnableDubbo;
@EnableDubbo
@SpringBootApplication
public class AppOrder {
  public static void main(String[] args) {
    SpringApplication.run(AppOrder.class, args);
}
}
 

yml

server:
  port: 8082    #tomcat端口号
###dubbo 注册服务名称
dubbo:
  application:
    name: order
  registry:
    address: zookeeper://192.168.91.5:2181
  consumer:  #调用服务的超时时间
    timeout: 5000 

 运行并且访问:

大家可以多启动几个 发布服务端口 然后 玩玩 就集群效果 我就不做展示了
