SpringBoot +LayUI+thymeleaf 实现一个功能（三) 新增

前端
dept.html


后端
dao层

package com.flo.dao;

import com.flo.po.Dept;
import org.springframework.stereotype.Component;

import java.util.List;
@Component("deptDao")
public interface IDeptDao {
    
    
    /**
     * 查询部门信息
     */
    List<Dept> findAll();

    void addDept(Dept dept);
}

mapper(新增部分)

<insert id="addDept" parameterType="com.flo.po.Dept">
        insert  into dept(parent_id,name,type,sort,status,create_time)
        values (#{parentId},#{name},#{type},#{sort},#{status},#{createTime})
    </insert>

Service 接口

void addDept(Dept dept);

接口实现层

@Override
    public void addDept(Dept dept) {
    
    
         iDeptDao.addDept(dept);
    }

封装后端类

网络状态常量类

package com.flo.util;

/**
 * 常量类
 */
public class Constants {
    
    

    public final static int OK_CODE = 200;
    public final static int FAIL_CODE = 400;
    public final static int OTHER_FAIL_CODE = 333;    // 其它错误
    public final static String OK_MSG = "请求成功";
    public final static String FAIL_MSG = "请求失败";
    public final static int STATUS_0 = 0;   // 可用状态
    public final static int STATUS_1 = 1;   // 禁用状态

    public final static String CACHE_NAME = "KACache";

}

}

控制层

//跳转接口
@RequestMapping("addDept")
    public String addDept(Integer type, Integer parentId, Model model){
    
    
        model.addAttribute("type",type+1);
        model.addAttribute("parentId",parentId);
        return "pages/addDept";
    }
    
//添加接口
@RequestMapping("dept/addDeptSubmit")
    @ResponseBody
    public R addDept(Dept dept){
    
    
        dept.setCreateTime(new Date());
        deptService.addDept(dept);
        return R.ok();
    }
