与springboot整合的三种方式

前期准备

创建两个springboot工程，分别为服务提供者和服务消费者，再创建一个maven project 的公共API

公共API

bean

package com.atguigu.gmall.bean;

import java.io.Serializable;

public class UserAddress implements Serializable {

    private Integer id;
    private String userAddress;
    private String userId;
    private String consignee;
    private String phoneNum;
    private String isDefault;

    public UserAddress() {
        super();
    }

    public UserAddress(Integer id, String userAddress, String userId, String consignee, String phoneNum, String isDefault) {
        this.id = id;
        this.userAddress = userAddress;
        this.userId = userId;
        this.consignee = consignee;
        this.phoneNum = phoneNum;
        this.isDefault = isDefault;
    }

    public Integer getId() {
        return id;
    }

    public void setId(Integer id) {
        this.id = id;
    }

    public String getUserAddress() {
        return userAddress;
    }

    public void setUserAddress(String userAddress) {
        this.userAddress = userAddress;
    }

    public String getUserId() {
        return userId;
    }

    public void setUserId(String userId) {
        this.userId = userId;
    }

    public String getConsignee() {
        return consignee;
    }

    public void setConsignee(String consignee) {
        this.consignee = consignee;
    }

    public String getPhoneNum() {
        return phoneNum;
    }

    public void setPhoneNum(String phoneNum) {
        this.phoneNum = phoneNum;
    }

    public String getIsDefault() {
        return isDefault;
    }

    public void setIsDefault(String isDefault) {
        this.isDefault = isDefault;
    }
}

service

package com.atguigu.gmall.service;

import com.atguigu.gmall.bean.UserAddress;

import java.util.List;

public interface OrderService {
    public List<UserAddress> initOrder(String userId);
}

package com.atguigu.gmall.service;


import com.atguigu.gmall.bean.UserAddress;

import java.util.List;

public interface UserService {
    public List<UserAddress> getUserAddressList(String userId);
}

服务提供者

service 实现

package com.atguigu.gmall.impl;

import com.alibaba.dubbo.config.annotation.Service;
import com.atguigu.gmall.bean.UserAddress;
import com.atguigu.gmall.service.UserService;
import org.springframework.stereotype.Component;

import java.util.Arrays;
import java.util.List;
@Service
@Component
public class UserServiceImpl implements UserService {
    public List<UserAddress> getUserAddressList(String userId) {
        UserAddress address1 = new UserAddress(1,"beijingshichangping","1", "lilaoshi","0536-0877651","yes");
        UserAddress address2 = new UserAddress(2, "shenzhenshi", "1", "wanglaoshi", "0536-0671118", "no");
        return Arrays.asList(address1, address2);
    }
}

        return addressList;
    }
}

三种整合方式

（1）导入dubbo-starter,在application.properties中配置属性，使用@Service【暴露服务】，使用@Reference 【引用服务】，只能配置接口层级

　　实现方式就是前期准备中的demo.

（2）保留dubbo xml 配置，通过@ImportResource 引入配置，可以配置方法级别

      保留 provider.xml ,使用@ImportResource 导入。示例：

　　

package com.atguigu.gmall;

import org.apache.dubbo.config.spring.context.annotation.EnableDubbo;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ImportResource;

//@EnableDubbo
@ImportResource(locations = "classpath:provider")
@SpringBootApplication
public class BootUserServiceProviderApplication {

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

}

然后注释application.properties 中的属性配置。

　　

（3）使用注解API的方式

　　API 配置类示例

package com.atguigu.gmall.config;

import com.atguigu.gmall.service.UserService;
import org.apache.dubbo.config.*;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

import java.util.ArrayList;
import java.util.List;

@Configuration
public class MyDubboConfig {

    @Bean
    public ApplicationConfig applicationConfig(){
        ApplicationConfig applicationConfig = new ApplicationConfig();
        applicationConfig.setName("boot-user-service-provider");
        return applicationConfig;
    }

    @Bean
    public RegistryConfig registryConfig(){
        RegistryConfig registryConfig = new RegistryConfig();
        registryConfig.setProtocol("zookeeper");
        registryConfig.setAddress("127.0.0.1:2181");
        return registryConfig;
    }

    @Bean
    public ProtocolConfig protocolConfig(){
        ProtocolConfig protocolConfig = new ProtocolConfig();
        protocolConfig.setName("dubbo");
        protocolConfig.setPort(20880);
        return protocolConfig;
    }

    @Bean
    public ServiceConfig<UserService> userServiceServiceConfig(UserService userService){
        ServiceConfig<UserService> userServiceServiceConfig = new ServiceConfig<>();
        userServiceServiceConfig.setInterface(UserService.class);
        userServiceServiceConfig.setRef(userService);
        userServiceServiceConfig.setVersion("1.0.0");

        MethodConfig methodConfig = new MethodConfig();
        methodConfig.setName("getUserAddressList");
        methodConfig.setTimeout(1000);
        List<MethodConfig> list = new ArrayList<>();
        list.add(methodConfig);
        userServiceServiceConfig.setMethods(list);

        return userServiceServiceConfig;
    }
}

　　启动类

　　

package com.atguigu.gmall;

import org.apache.dubbo.config.spring.context.annotation.DubboComponentScan;
import org.apache.dubbo.config.spring.context.annotation.EnableDubbo;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ImportResource;

//@EnableDubbo
//@ImportResource(locations = "classpath:provider")
@DubboComponentScan("com.atguigu.gmall")
@SpringBootApplication
public class BootUserServiceProviderApplication {

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

}
