1. 环境准备
2.导入项目
3. guns 开发

本文档以较老版本guns-v3.0.1 为例

1. 环境准备

以实际为准

2.导入项目

打开项目
修改为本机JDK
添加maven 【提前配置好maven环境】
guns-parent 下的pom.xml文件右击，找到Add as maven
利用sql文件，导入到数据库中
自定义修改端口【本机设置的8080】
数据库设置【根据实际情况进行修改】
启动项目
出错最多原因【mysql驱动版本】

Error creating bean with name 'sqlSessionFactory' defined in class path resource [com/baomidou/mybatisplus/spring/boot/starter/MybatisPlusAutoConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.apache.ibatis.session.SqlSessionFactory]: Factory method 'sqlSessionFactory' threw exception; nested exception is com.baomidou.mybatisplus.exceptions.MybatisPlusException: Error: GlobalConfigUtils setMetaData Fail !  Cause:java.sql.SQLException: Unknown system variable 'tx_isolation'

根据本机数据库版本修改maven中sql驱动版本即可，本机修改版本为8.0及以上版本可正常运行

3. guns 开发

3.1 准备数据库表

CREATE TABLE `my_order` (
  `id` int NOT NULL AUTO_INCREMENT COMMENT '主键id',
  `user` varchar(255) DEFAULT NULL COMMENT '下单人名称',
  `place` varchar(255) DEFAULT NULL COMMENT '地点',
  `goods` varchar(255) DEFAULT NULL COMMENT '商品名称',
  `createtime` datetime DEFAULT NULL COMMENT '下单时间',
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=3 DEFAULT CHARSET=utf8mb3

自定义添加一些数据

3.2 mybatis-plus 代码生成

修改为本机项目目录
修改为本机数据库设置
设置单独生成my_order表【不加生成所有表】
运行后删除TTT文件夹【本项目无用】
自动生成业务代码

生成文件

3.3 菜单设置和全限配置

重新加载后可显示页面

3.4 修改前端js文件

3.5 显示列表订单业务代码编写

package com.stylefeng.guns.modular.order.controller;

import com.baomidou.mybatisplus.mapper.EntityWrapper;
import com.baomidou.mybatisplus.mapper.Wrapper;
import com.stylefeng.guns.common.persistence.dao.MyOrderMapper;
import com.stylefeng.guns.common.persistence.model.MyOrder;
import com.stylefeng.guns.core.base.controller.BaseController;
import com.stylefeng.guns.core.util.ToolUtil;
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 org.springframework.ui.Model;
import org.springframework.web.bind.annotation.PathVariable;

import java.util.List;

/**
 * 订单业务控制器
 *
 * @author fengshuonan
 * @Date 2022-02-20 10:39:02
 */
@Controller
@RequestMapping("/order")
public class OrderController extends BaseController {

    private String PREFIX = "/order/order/";

    @Autowired
    private MyOrderMapper myOrderMapper;

   
    /**
     * 获取订单业务列表
     */
    @RequestMapping(value = "/list")
    @ResponseBody
    public Object list(String condition) {
            //查询全部
            List<MyOrder> myOrders = myOrderMapper.selectList(null);
            return myOrders;
     
    }
}

3.7 显示列表订单管理-----搜索功能

package com.stylefeng.guns.modular.order.controller;

import com.baomidou.mybatisplus.mapper.EntityWrapper;
import com.baomidou.mybatisplus.mapper.Wrapper;
import com.stylefeng.guns.common.persistence.dao.MyOrderMapper;
import com.stylefeng.guns.common.persistence.model.MyOrder;
import com.stylefeng.guns.core.base.controller.BaseController;
import com.stylefeng.guns.core.util.ToolUtil;
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 org.springframework.ui.Model;
import org.springframework.web.bind.annotation.PathVariable;

import java.util.List;

/**
 * 订单业务控制器
 *
 * @author fengshuonan
 * @Date 2022-02-20 10:39:02
 */
@Controller
@RequestMapping("/order")
public class OrderController extends BaseController {

    private String PREFIX = "/order/order/";

    @Autowired
    private MyOrderMapper myOrderMapper;
    

    /**
     * 获取订单业务列表
     */
    @RequestMapping(value = "/list")
    @ResponseBody
    public Object list(String condition) {
        if (ToolUtil.isNotEmpty(condition)){
//            搜索
            EntityWrapper<MyOrder> objectEntityWrapper = new EntityWrapper<>();
            Wrapper<MyOrder> goods = objectEntityWrapper.like("goods", "%" + condition + "%");
            List<MyOrder> myOrders = myOrderMapper.selectList(goods);
            return myOrders;
        }else {
            //查询全部
            List<MyOrder> myOrders = myOrderMapper.selectList(null);
            return myOrders;
        }
    }

}

3.8 新增订单业务

后端

    /**
     * 新增订单业务
     */
    @RequestMapping(value = "/add")
    @ResponseBody
    public Object add(MyOrder myOrder) {
        if (myOrder != null){
            myOrder.setCreatetime(new Date());
        }
        Integer insert = myOrderMapper.insert(myOrder);
        return super.SUCCESS_TIP;
    }

前端
修改js

添加菜单

添加角色
