--------------------

## 一、项目模块构建 ##

*  hospital-manage ：医院接口模拟端 (已开发，直接使用)
 *  yygh-parent ：根目录，管理子模块：
    
     *  common ：公共模块父节点
        
         *  common-util ：工具类模块，所有模块都可以依赖于它
         *  rabbit-util ：RabbitMQ 业务封装
         *  service-util ：service 服务的工具包，包含 service 服务的公共配置类，所有 service 模块依赖于它
 *  server-gateway：服务网关
 *  model：实体类模块
 *  service：API 接口服务父节点
    
     *  service-hosp：医院 API 接口服务
     *  service-cmn：公共 API 接口服务
     *  service-user：用户 API 接口服务
     *  service-order：订单 API 接口服务
     *  service-oss：文件 API 接口服务
     *  service-sms：短信 API 接口服务
     *  service-task：定时任务服务
     *  service-statistics：统计 API 接口服务
 *  service-client：Feign 服务调用父节点
    
     *  service-cmn-client：公共 API 接口
     *  service-hosp-client：医院 API 接口
     *  service-order-client：订单 API 接口
     *  service-user：用户 API 接口

## 二、导入 SQL 文件 ##

## 三、构建父工程 yygh-parent ##

父工程目录我们已经通过 git 引入

## 四、搭建 common 模块 ##

*  common：公共模块父节点
    
     *  common-util：工具类模块，所有模块都可以依赖于它
     *  service-util：service 服务的工具包，包含 service 服务的公共配置类，所有 service 模块依赖于它

### 1. 搭建父模块 ###

点击 yygh-parent，选择 New–>Module ，操作如下

![在这里插入图片描述][2d4e0617e80f4b5f99d0b2dd3e6afe7e.png]

完成，删除 src 目录，结构如下

![在这里插入图片描述][c0f5ce91907e4b6fb28cd19aad23c6ab.png]

修改配置 pom.xml

### 2. 搭建 common-util 模块 ###

点击 common，选择 New –> Module，操作如下

![在这里插入图片描述][65dee5b7361a42469bf99891ad7e5f4d.png]  
完成，结构如下

![在这里插入图片描述][e92fe4a6326b405882764138044d593f.png]  
修改配置 pom.xml

添加工具类

![在这里插入图片描述][bf4fd06ab51a4b50b2c86a086252b56a.png]

<table> 
 <thead> 
  <tr> 
   <th>工具类</th> 
   <th>说明</th> 
  </tr> 
 </thead> 
 <tbody> 
  <tr> 
   <td>YyghException</td> 
   <td>自定义全局异常</td> 
  </tr> 
  <tr> 
   <td>Result API</td> 
   <td>统一返回结果封装类</td> 
  </tr> 
  <tr> 
   <td>ResultCodeEnum</td> 
   <td>API统一返回结果状态信息</td> 
  </tr> 
  <tr> 
   <td>BeanUtils</td> 
   <td>实体bean copy工具类</td> 
  </tr> 
  <tr> 
   <td>MD5</td> 
   <td>MD5加密工具类</td> 
  </tr> 
 </tbody> 
</table>

### 3. 搭建 service-util 模块 ###

搭建过程同 common-util，如图  
![在这里插入图片描述][768e9b9b3bf041908181230e34cd9b5d.png]

修改配置 pom.xml

添加 service-util 公共类

![在这里插入图片描述][cdb9f20bc44244a69aa14af430ea2a89.png]

<table> 
 <thead> 
  <tr> 
   <th>配置类</th> 
   <th>说明</th> 
  </tr> 
 </thead> 
 <tbody> 
  <tr> 
   <td>MybatisPlusConfig</td> 
   <td>MybatisPlus配置类</td> 
  </tr> 
  <tr> 
   <td>CommonMetaObjectHandler</td> 
   <td>Mybatis plus Handler配置类</td> 
  </tr> 
 </tbody> 
</table>

package com.fancy.yygh.common.config;
    
    
    import com.baomidou.mybatisplus.extension.plugins.OptimisticLockerInterceptor;
    import com.baomidou.mybatisplus.extension.plugins.PaginationInterceptor;
    import org.mybatis.spring.annotation.MapperScan;
    import org.springframework.context.annotation.Bean;
    import org.springframework.context.annotation.Configuration;
    import org.springframework.transaction.annotation.EnableTransactionManagement;
    
    /**
     * MybatisPlus配置类
     */
    @EnableTransactionManagement //事务处理
    @Configuration
    @MapperScan("com.atguigu.yygh.*.mapper")
    public class MybatisPlusConfig {
        
    
        /**
         * 分页插件
         */
        @Bean
        public PaginationInterceptor paginationInterceptor() {
        
            PaginationInterceptor paginationInterceptor = new PaginationInterceptor();
    // paginationInterceptor.setLimit(你的最大单页限制数量，默认 500 条，小于 0 如 -1 不受限制);
            return paginationInterceptor;
        }
    
        /**
         * 乐观锁配置
         */
        @Bean
        public OptimisticLockerInterceptor optimisticLockerInterceptor() {
        
            return new OptimisticLockerInterceptor();
        }
    }

package com.fancy.yygh.common.handler;
    
    import com.baomidou.mybatisplus.core.handlers.MetaObjectHandler;
    import org.apache.ibatis.reflection.MetaObject;
    import org.springframework.stereotype.Component;
    
    import java.util.Date;
    
    /**
     * Mybatis plus Handler配置类
     */
    @Component
    public class CommonMetaObjectHandler implements MetaObjectHandler {
        
    
        @Override
        public void insertFill(MetaObject metaObject) {
        
            this.setFieldValByName("createTime", new Date(), metaObject);
            this.setFieldValByName("updateTime", new Date(), metaObject);
        }
        @Override
        public void updateFill(MetaObject metaObject) {
        
            this.setFieldValByName("updateTime", new Date(), metaObject);
        }
    }

## 五、搭建 model 模块 ##

搭建过程同 common

**修改 pom.xml**

### 引入实体类 ###

将实体类都引入进来，后续不再单独引入，实体类没有业务逻辑，提前引入，方便后续开发。

## 六、搭建 service 模块 ##

*  service ：service 模块父节点
    
     *  service-user ：会员服务模块
     *  …

**修改配置 pom.xml**
