1、环境准备
操作系统：win10
开发工具：IntelliJ IDEA
数据库：MySQL
底层工具：dubbo admin（没有也完全可以） + zookeeper
框架：springMVC+mybatis
工程：maven
2、工程搭建后的结构图
开始搭建前，先看一下搭建好后的结构
其中：tea-api模块：接口和实体类的信息，也是暴露给服务调用者的模块
tea-service模块下的2个子模块：basic-service和biz-server，是服务提供者，basic是提供数据库层的服务，biz提供其他的，比如redis 的调用等，示例中，只是写了一段输出
tea-web模块下的crm-web模块，是服务调用者，对外展示的通道（crm嘛，当然就能想到后台管理系统了）
3、搭建前的准备
3.1、安装zookeeper
3.1.1、下载zookeeper
直接官网下载：https://www.apache.org/dyn/closer.cgi/zookeeper/
3.1.2：修改zk 的配置文件
下载并且解压后，进入zk 的conf目录，将zoo_sample.cfg文件复制并命名为zoo.cfg，修改其中的配置：
如图中标红的，一个是zk 的节点存放目录，clientPort是zk 的端口
3.1.3：启动zk服务
改完后，保存，进入bin目录，执行zkServer.cmd文件，启动zk服务
3.2：其他的准备
安装maven和idea，这些部分就不一一介绍了，度娘一下就好
4、搭建环境
4.1、新建project
idea和eclipse 的不同点其中一个就是project+module，idea下新建project需要新打开窗口(一个窗口=一个项目），但是project下面可以new module
因为是一个总的父类工程，所以这个下面，核心的就是一个pom文件，如下

4.2、新建模块api
api模块下开发实体类和接口，这也是对服务消费者直接暴露，因为这个对外只是提供jar包，直接展示个模块的结构好了
4.3、新建服务提供者模块
这个模块下面暂时提供了两个模块：basic和biz，分别对应数据库服务和其他(还没想好具体放哪些服务)
4.3.1、搭建basic服务者模块
basicService下面，写接口的实现类；mapper写的是mybatis的dao层接口，resources下面的conf存放配置文件，mapper文件下存放的mybatis的映射文件，META-INF/spring下面存放的就是spring和dubbo的xml配置文件

<dubbo:protocol name="${dubbo.protocol.name}" port="${dubbo.protocol.port}" accepts="400" threads="500" threadpool="fixed" />
<!--操作sysUser的服务-->
<dubbo:service interface="com.cn.chuanyi.service.basic.sysUser.SysUserService" ref="sysUserServiceImpl"/>
</beans>
4.3.2、编码开始
首先，需要在basic模块下写数据库的dao层接口和对应的mapper文件
package com.cn.chuanyi.mapper.sysUser;
import com.cn.chuanyi.entity.basic.sysUser.SysUserEntity;
import java.util.List;
/**
* Created by guxuhua on 2018/7/31.
*/
public interface SysUserDao {
/**
* 查询系统中所有的sysuser
*
* */
List<SysUserEntity> getSysUsers() throws Exception;
}
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.cn.chuanyi.mapper.sysUser.SysUserDao">
<resultMap id="sysUserResultMap" type="com.cn.chuanyi.entity.basic.sysUser.SysUserEntity">
<result column="userId" property="userId"/>
<result column="username" property="userName"/>
<result column="passwd" property="passWord"/>
<result column="createdate" property="createDate"/>
</resultMap>
<select id="getSysUsers" resultMap="sysUserResultMap">
SELECT
T.userId,
T.username,
T.passwd,
T.createdate
FROM sys_user T
</select>
</mapper>
接着在api模块下，新写一个service接口：
package com.cn.chuanyi.service.basic.sysUser;
import com.cn.chuanyi.entity.basic.sysUser.SysUserEntity;
import java.util.List;
/**
* Created by guxuh on 2018/7/31.
*/
public interface SysUserService {
/**
* 查询sysuser信息
* SELECT * FROM sys_user;
*/
List<SysUserEntity> getSysUsers() throws Exception;
}
然后，在basic模块下，实现这个service 接口
package com.cn.chuanyi.basicService.sysUser;
import com.cn.chuanyi.entity.basic.sysUser.SysUserEntity;
import com.cn.chuanyi.mapper.sysUser.SysUserDao;
import com.cn.chuanyi.service.basic.sysUser.SysUserService;
import org.apache.log4j.Logger;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import java.util.List;
/**
* Created by guxuh on 2018/7/31.
*/
@Service
public class SysUserServiceImpl implements SysUserService {
/*log4j的输出*/
private static final Logger logger = Logger.getLogger(SysUserServiceImpl.class);
@Autowired
private SysUserDao sysUserDao;//操作数据库
/**
* 查询sysuser信息
* SELECT * FROM sys_user;
*/
@Override
public List<SysUserEntity> getSysUsers() throws Exception {
logger.debug(">>>>>查询所有的sys用户<<<<<");
return sysUserDao.getSysUsers();
}
}
最后配置在spring-context-dubbo.xml这个文件里头(配置对外提供服务的service)
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:dubbo="http://code.alibabatech.com/schema/dubbo"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
http://code.alibabatech.com/schema/dubbo http://code.alibabatech.com/schema/dubbo/dubbo.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">
<context:component-scan base-package="com.cn.chuanyi" />
<!--${dubbo.registry.address}-->
<dubbo:registry address="${dubbo.registry.address}"/>
<dubbo:protocol name="${dubbo.protocol.name}" port="${dubbo.protocol.port}" accepts="400" threads="500" threadpool="fixed" />
<!--操作sysUser的服务-->
<dubbo:service interface="com.cn.chuanyi.service.basic.sysUser.SysUserService" ref="sysUserServiceImpl"/>
</beans>
<dubbo:service interface="com.cn.chuanyi.service.basic.sysUser.SysUserService" ref="sysUserServiceImpl"/>，这部分，就是注册一个服务到dubbo，好了，basic这部分的服务提供者的代码和配置文件完成了，启动下看下
4.3.3：启动服务
前提：zk已经启动了
dubbo服务的启动可以使用dubbo提供的container进行启动，我这里就是用的container启动的，不过，对于通过container启动，需要注意：spring和dubbo对应的xml配置文件，必须放在META-INF/spring下面，
有兴趣的同学，可以读下dubbo的这块源码，
好了，接着，就是以main方法的形式启动服务提供者，如下结果，表示启动成功
启动的同时，zk 的cmd窗口也会有消息滑动。
4.4、新建服务消费者模块（crm模块）
结构如下图所示：
4.4.1、配置内容

最后，作为web工程，就必须使用web.xml了

4.4.2、编写测试用代码
package com.cn.chuanyi.view.sysUser;
import com.alibaba.fastjson.JSONObject;
import com.cn.chuanyi.entity.basic.sysUser.SysUserEntity;
import com.cn.chuanyi.service.basic.sysUser.SysUserService;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import java.util.List;
/**
* Created by guxuh on 2018/7/31.
* 操作系统管理员数据
*/
@Controller
@RequestMapping("/sysUser")
public class SysUserController {
/*log4j输出*/
protected Logger logger = LoggerFactory.getLogger(this.getClass());
/*注入待操作的服务*/
@Autowired
private SysUserService sysUserService;
/**
* 获取所有的sysuser
* */
@RequestMapping("getAllSysUsers")
@ResponseBody
public JSONObject getAllSysUsers() throws Exception{
JSONObject returnValues = new JSONObject();
logger.debug(">>>>>查询所有的sys用户<<<<<");
List<SysUserEntity> entities = sysUserService.getSysUsers();
if(null!=entities && !entities.isEmpty()){
returnValues.put("count",entities.size());
}else{
returnValues.put("count",0);
}
returnValues.put("sysUsers",entities);
return returnValues;
}
}
4.4.3、启动web应用
如图，就表示启动成功了
5、测试
直接浏览器输入：http://localhost:8181/crm/sysUser/getAllSysUsers
就可以看到获取到的数据了
如上，就是一个基础的dubbo环境的搭建，在应用搭建和启动的过程中出现的问题，很多场景下通过分析日志就可以解决，要是还是不行，还有万能的度娘。
