一、创建his-medicine模块

            0) 在创建好的若依后端项目中创建一个maven模块his-medicine

         1）his模块的整合步骤

                ①）his的依赖

                这个是若依项目所有系统模块都需要添加的依赖，domain和controller继承的类就在这里面。

 <!-- 通用工具-->
        <dependency>
            <groupId>com.ruoyi</groupId>
            <artifactId>ruoyi-common</artifactId>
        </dependency>

                ②）安装his模块

               ③）  在ruoyi-admin模块中引入his模块

                        实质上在项目运行时，实际运行的是ruoyi-admin项目，所有其他模块的文件最终都放到此模块下。

          2）实现his的思路

                          his医院信息管理系统的业务对象包括生产厂家、供应商、药品、订单、订单详情等等，要想完成一个his，首先需要把所有的业务对象的增删改查基础代码写出来，单表的增删改查过程可以直接使用代码生成器，但是代码生成器有时候前端会漏写，后端有可能包路径不对，可以尝试自己手动写一个系统对象，熟悉若依的系统框架到底是怎么运行的；

                           然后再考虑复杂的业务场景。

                

二、生产厂家系统：

        1）数据库sql建表语句

drop table if exists his_medicine_factory
CREATE TABLE `his_medicine_factory` (
  `factory_id` bigint(20) NOT NULL AUTO_INCREMENT COMMENT '厂家ID',
  `factory_name` varchar(100) DEFAULT NULL COMMENT '厂家名称',
  `factory_code` varchar(50) NOT NULL COMMENT '厂家编码',
  `factory_person` varchar(50) NOT NULL COMMENT '厂家联系人',
  `factory_phone` char(11) DEFAULT '00' COMMENT '联系方式',
  `factory_keyword` varchar(50) DEFAULT '' COMMENT '厂家关键字',
  `factory_address` varchar(100) DEFAULT '' COMMENT '厂家地址',
  `status` char(1) DEFAULT '0' COMMENT '（0正常 1 禁用）',
  `create_by` varchar(64) DEFAULT '' COMMENT '创建者',
  `create_time` datetime DEFAULT NULL COMMENT '创建时间',
  `update_by` varchar(64) DEFAULT '' COMMENT '更新者',
  `update_time` datetime DEFAULT NULL COMMENT '更新时间',
  `remark` varchar(500) DEFAULT NULL COMMENT '备注',
  PRIMARY KEY (`factory_id`)
	
) ENGINE=InnoDB AUTO_INCREMENT=101 DEFAULT CHARSET=utf8 COMMENT='生产厂家信息表';

        2）单表增删改查的实现

                        写一个生产厂家的管理系统可以对照写好的部门系统SysPost格式，从后端到前端不管是代码的格式还是界面elementplus标签 岗位系统是比较好的参考例子。

                〇)domain

                        通过若依写好的岗位管理系统发现所有实体类都继承了BaseEntity

                        BaseEntity主要用来存放一些公共的属性值，对应的也就是数据库中表中的公共字段

                        那根据数据库创建的实体类MedicineFactory也继承BaseEntity

package com.ruoyi.domain;

import com.ruoyi.common.core.domain.BaseEntity;
import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;
import org.springframework.format.annotation.DateTimeFormat;

import java.sql.Date;

/**
 * @author rk
 * @description: TODO
 * @date 2024/8/28 19:08
 */
@Data
@NoArgsConstructor
@AllArgsConstructor
public class MedicineFactory extends BaseEntity {
    private Long factoryId;
    private String factoryName;
    private String factoryCode;
    private String factoryPerson;
    private String factoryPhone;

    private String factoryKeyword;

    private String factoryAddress;
    private String status;
    private String createBy;
    private Date createTime;
    private String updateBy;
    private Date updateTime;
    private String remake;

    @DateTimeFormat(pattern = "yyyy-MM-dd")
    private Date startTime;
    @DateTimeFormat(pattern = "yyyy-MM-dd" )
    private Date endTime;
}

                ①mapper    没有影响 ，照写

    List<MedicineFactory> selectFactoryList(MedicineFactory medicineFactory);

    int updateFactory(MedicineFactory medicineFactory);

    int addFactory(MedicineFactory medicineFactory);

    int deleteFactoryById(Long  id);

    MedicineFactory selectFactoryById(Long id);
}

                ②service  没有影响 ，照写

    }
}

                ③controller

                        controller类的代码放在ruoyi-admin目录下；

                        需要继承BaseController ；

                        每个单元方法上添加检验权限标识符的注解@PreAuthorize

package com.ruoyi.web.controller.medicine;

import com.ruoyi.common.annotation.Log;
import com.ruoyi.common.core.controller.BaseController;
import com.ruoyi.common.core.domain.AjaxResult;
import com.ruoyi.common.core.page.TableDataInfo;
import com.ruoyi.common.enums.BusinessType;
import com.ruoyi.domain.MedicineFactory;
import com.ruoyi.service.IHisMedicineFactory;
import com.ruoyi.system.domain.SysPost;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.security.access.prepost.PreAuthorize;
import org.springframework.validation.annotation.Validated;
import org.springframework.web.bind.annotation.*;

import java.util.List;

/**
 * @author rk
 * @description: TODO
 * @date 2024/8/28 20:34
 */
@RestController
@RequestMapping("medicine/factory")
public class MedicineController extends BaseController {
    @Autowired
    private IHisMedicineFactory hisMedicineFactory;

    /**
     *
     */
    @PreAuthorize("@ss.hasPermi('medicine:factory:list')")
    @GetMapping("/list")
    public TableDataInfo list(MedicineFactory medicineFactory)
    {
        startPage();
        List<MedicineFactory> list = hisMedicineFactory.selectFactoryList(medicineFactory);
        return getDataTable(list);
    }

    /**
     * 根据岗位编号获取详细信息
     */
    @PreAuthorize("@ss.hasPermi('medicine:factory:list')")
    @GetMapping(value = "/list/{id}")
    public AjaxResult getInfo(@PathVariable Long id)
    {
        return success(hisMedicineFactory.selectFactoryById(id));
    }



    @PreAuthorize("@ss.hasPermi('medicine:factory:add')")
    @PostMapping
    public AjaxResult add(@Validated @RequestBody MedicineFactory medicineFactory)
    {
        medicineFactory.setCreateBy(getUsername());
        return toAjax(hisMedicineFactory.addFactory(medicineFactory));
    }

    /**
     * 修改岗位
     */
    @PreAuthorize("@ss.hasPermi('medicine:factory:edit')")
    @PutMapping
    public AjaxResult edit(@Validated @RequestBody MedicineFactory medicineFactory)
    {
        medicineFactory.setUpdateBy(getUsername());
        return toAjax(hisMedicineFactory.updateFactory(medicineFactory));
    }

    /**
     * 删除岗位
     */
    @PreAuthorize("@ss.hasPermi('medicine:factory:remove')")
    @DeleteMapping("/{id}")
    public AjaxResult remove(@PathVariable Long id)
    {
        return toAjax(hisMedicineFactory.deleteFactoryById(id));
    }



}

        3）对应的前端界面

                        〇）界面效果

                        ①）登录若依管理系统手动添加对应的路由地址和url

                       ②） 前端代码

                                界面的elementplus标签和script内语法可以参照岗位系统的前端界面post.vue代码。
