dcy-fast

平台简介

一直想做一款后台管理系统,看了很多优秀的开源项目但是发现没有合适的。于是利用空闲休息时间开始自己写了一套后台系统。参考若依框架,自己编写dcy-fast框架。 她可以用于所有的Web应用程序,如网站管理后台,网站会员中心,CMS,CRM,OA。所有前端后台代码封装过后十分精简易上手,出错概率低。同时支持移动客户端访问。系统会陆续更新一些实用功能。

dcy-fast是一套全部开源的快速开发平台,毫无保留给个人及企业免费使用。

TODO-LIST

1.优化代码(暂无任务了)

内置功能

  1. 用户管理:用户是系统操作者,该功能主要完成系统用户配置。
  2. 部门管理:配置系统组织机构(公司、部门、小组),树结构展现支持数据权限。
  3. 岗位管理:配置系统用户所属担任职务。
  4. 菜单管理:配置系统菜单,操作权限,按钮权限标识等。
  5. 角色管理:角色菜单权限分配、设置角色按机构进行数据范围权限划分。
  6. 字典管理:对系统中经常使用的一些较为固定的数据进行维护。
  7. 参数管理:对系统动态配置常用参数。
  8. 操作日志:系统正常操作日志记录和查询;系统异常信息日志记录和查询。
  9. 定时任务:在线(添加、修改、删除)任务调度包含执行结果日志。
  10. 代码生成:前后端代码的生成(controller、service、mapper、xml、entity、dto、dtomapper、vue)支持CRUD下载 。
  11. 系统接口:根据业务代码自动生成相关的api接口文档。
  12. 连接池监视:监视当前系统数据库连接池状态,可进行分析SQL找出系统性能瓶颈。
  13. 文件管理:fastDFS和Minio已经都集成。

如何运行

  1. 准备redis 修改 application-dev.yml 里面的配置项
  2. 准备mysql 修改 application-dev.yml 里面的配置项
    • 注意:创建数据库,不需要导入表结果,空的数据库即可,因为flyway会自动创建
  3. 如果需要文件上传请选择 fastdfs或者minio 安装教程网上找即可,如果需要后续我会出文档。
  4. banner.txt 文件控制台有乱码,可以删除或换成自己喜欢的
  5. 修改 application.ymlspring.flyway.enabled 变成 true
  6. 直接运行 WebApplication 即可
  7. 访问接口访问地址:http://localhost:8999/doc.html
    • 用户名:admin;密码:123456

数据权限怎么玩

  1. 定义mapper 和 sql
/**
 * 分页查询
 *
 * @param page    分页对象
 * @param wrapper 条件参数
 * @return
 */
@DataScope(value = {
        @DataColumn(alias = "userInfo", name = "dept_id")
})
IPage<UserInfo> selectPageList(IPage<UserInfo> page, @Param(Constants.WRAPPER) Wrapper wrapper);
<select id="selectPageList" resultType="com.dcy.system.model.UserInfo">
    select <include refid="Base_Column_List_Alias"/>,
            dept.name as dept_name
    from sys_user_info userInfo left join sys_dept dept on userInfo.dept_id = dept.id
    ${ew.customSqlSegment}
</select>
  1. service调用
public IPage<UserInfo> pageList(UserInfo userInfo) {
    QueryWrapper<UserInfo> queryWrapper = Wrappers.<UserInfo>query();
    queryWrapper.eq("userInfo." + BaseModel.DEL_FLAG, BaseModelDelFlagEnum.NORMAL.code);
    queryWrapper.like(StrUtil.isNotBlank(userInfo.getUsername()), "userInfo." + UserInfo.USERNAME, userInfo.getUsername());
    if (StrUtil.isNotBlank(userInfo.getDeptId())) {
        queryWrapper.and(userInfoQueryWrapper -> {
                    userInfoQueryWrapper.eq("userInfo." + UserInfo.DEPT_ID, userInfo.getDeptId())
                            .or().inSql("userInfo." + UserInfo.DEPT_ID, "SELECT sys_dept.id FROM sys_dept WHERE FIND_IN_SET('" + userInfo.getDeptId() + "', ancestors)");
                }
        );
    }
    return baseMapper.selectPageList(getPagePlusInfo(userInfo), queryWrapper);
}
  1. 关键性代码处理
com.dcy.db.base.interceptor.DataPermissionInterceptor#dataPermissionHandler()
  1. 思路
    • 首先在需要的权限过滤的mapper上面加上@DataScope注解,然后添加@DataColumn字段,alias表示表别名;name表示字段名称
    • 然后 com.dcy.db.base.interceptor.DataPermissionInterceptor#dataPermissionHandler() 会根据权限自动拼接sql 实现数据过滤
      • @DataScope注解 的 type字段可以为不同的类型单独处理不同的数据权限,@DataColumn 也是一样的逻辑,每个字段都可以单独处理
      • 查询数据权限 com.dcy.db.base.service.IDataScopeService 接口

工作流使用方式(建议有点基础使用)

  1. 先运行项目
  2. 在web页面【模型管理】下面新增模型,把oa模块下的 resources/process-test下的请假流程.bpmn20.xml文件导入进去
  3. 然后部署此流程实例
  4. 在【流程管理】下 设置审批人,对应功能 设置审批,支持角色,人员,部门
  5. 可以开始测试了,创建申请,然后查询代办任务,已办任务,追踪流程等待。其他的自己发掘。。。
