SpringBoot 整合Mybatis 和Dubbo

最近编写了一部分SpringBoot的代码，想整理一个基于SpringBoot 的RPC 远程服务调用框架。

第一步：整合SpringBoot和Mybatis,具体参考:https://blog.csdn.net/zhouzhiwengang/article/details/81677256

第二步：整合SpringBoot 和Dubbo.

1、pom.xml 加载dubbo 依赖的jar 文件。

 <!-- Spring Boot Dubbo 依赖 -->
        <dependency>
            <groupId>org.apache.zookeeper</groupId>
            <artifactId>zookeeper</artifactId>
            <version>3.4.8</version>
        </dependency>
        <dependency>
            <groupId>com.101tec</groupId>
            <artifactId>zkclient</artifactId>
            <version>0.7</version>
        </dependency>
        <dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>dubbo</artifactId>
            <version>2.8.4</version>
            <exclusions>
                <exclusion>
                    <groupId>org.springframework</groupId>
                    <artifactId>spring</artifactId>
                </exclusion>
            </exclusions>
        </dependency>

2、框架的层次结构如下图所示:

各模块功能分区简单说明下：

api:定义service 接口和实体对象定义。

dao:定义mapper 接口和映射文件关系绑定。

service:service 接口实现，基于mapp接口和映射文件。

web:主要业务逻辑实现层。

3、实现远程接口接口声明和实现。

api层：

package com.zzg.api;

import com.zzg.pojo.User;

public interface UserService {
    int deleteByPrimaryKey(Long id);

    int insert(User record);

    int insertSelective(User record);

    User selectByPrimaryKey(Long id);

    int updateByPrimaryKeySelective(User record);

    int updateByPrimaryKey(User record);
}

service层：

/**
 * Copyright (C), 2015-2018, 周氏集团有限公司
 * FileName: UserServiceImpl
 * Author:   Administrator
 * Date:     2018/8/16 1:58
 * Description: 用户Service
 * History:
 * <author>          <time>          <version>          <desc>
 * 作者姓名           修改时间           版本号              描述
 */
package com.zzg.service.impl;

import com.zzg.api.UserService;
import com.zzg.dao.UserMapper;
import com.zzg.pojo.User;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
import org.springframework.stereotype.Service;

import javax.annotation.Resource;

/**
 * 〈一句话功能简述〉<br> 
 * 〈用户Service〉
 *
 * @author Administrator
 * @create 2018/8/16
 * @since 1.0.0
 */
@Service
public class UserServiceImpl implements UserService {
    @Resource
    private UserMapper mapper;

    @Override
    public int deleteByPrimaryKey(Long id) {
        return mapper.deleteByPrimaryKey(id);
    }

    @Override
    public int insert(User record) {
        return mapper.insert(record);
    }

    @Override
    public int insertSelective(User record) {
        return mapper.insertSelective(record);
    }

    @Override
    public User selectByPrimaryKey(Long id) {
        return mapper.selectByPrimaryKey(id);
    }

    @Override
    public int updateByPrimaryKeySelective(User record) {
        return 0;
    }

    @Override
    public int updateByPrimaryKey(User record) {
        return mapper.updateByPrimaryKey(record);
    }
}

service 服务启动：扫描dao 和加载provider.xml文件

/**

 * FileName: EmsServiceApplication
 * Author:   Administrator
 * Date:     2018/8/16 1:33

 * 作者姓名           修改时间           版本号              描述
 */
package com.zzg.service;

import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ImportResource;

/**

 */
@SpringBootApplication
@MapperScan("com.zzg.dao")
@ImportResource("classpath:provider.xml")
public class EmsServiceApplication {
    public static void main(String[] args) {
        SpringApplication.run(EmsServiceApplication.class, args);
        System.out.println("============= SpringBoot Ems Service Start Success =============");
    }
}

    <!-- 暴露dubbo服务的方式二 -->
    <!-- 使用xml配置方式申明暴露一个接口服务，在程序启动的时候会自动注册到zookeeper。
         等同于在类上打@service注解，打了注解就必须要用annotation指定启动扫描路径，使用这种方式，就不需要指定annotation了-->

    <!-- 用户服务接口 -->
    <dubbo:service interface="com.zzg.api.UserService" ref="userService" />

    <bean id="userService" class="com.zzg.service.impl.UserServiceImpl"/>
</beans>
