基于项目的任务显示，最直观的就是甘特图显示，所以今天就说甘特图的显示

经过选择，最终选择dhtmlx-gantt组件，使用最新的8.0.3版本，当然这个组件就是一些高级功能需要付费。

1、后端代码

获取项目任务相关信息如下：

@Overridepublic Result<?> taskGantt(Map<String, Object> mmap) {String projectId = MapUtils.getString(mmap, "projectId");List<Map> listStagesGantt = taskStagesMapper.selectTaskStagesGanttByProjectId(projectId);List<Map> listTasksGantt = baseMapper.selectTaskGanttByProjectId(projectId);if (!CollectionUtils.isEmpty(listStagesGantt)) {if (!CollectionUtils.isEmpty(listTasksGantt)) {for (Map stagesmap : listStagesGantt) {for (Map tasksmap : listTasksGantt) {if (ObjectUtils.isEmpty(tasksmap.get("parent"))) {tasksmap.replace("parent", stagesmap.get("id"));}}}Map<String, Object> tasksmap = new HashMap<String, Object>();listStagesGantt.addAll(listTasksGantt);tasksmap.put("data", listStagesGantt);return Result.OK(tasksmap);} else {Map<String, Object> tasksmap = new HashMap<String, Object>();tasksmap.put("data", listStagesGantt);return Result.OK(tasksmap);}} else {return Result.error("获取不到数据");}}

其中用到的两个sql如下，注意下面对日期做了格式转换：

 @Select("select id,name as text,null assign_to,null as start_date,null as end_date,sort,null parent from tw_task_stages where project_id = #{projectId} order by sort" )List<Map> selectTaskStagesGanttByProjectId(@Param("projectId") String  projectId);@Select("select id,name as text,assign_to,DATE_FORMAT(begin_time,'%d-%m-%Y') as start_date,DATE_FORMAT(end_time,'%d-%m-%Y') as end_date, id_num as sort, pid as parent from tw_task where project_id = #{projectId} order by sort")List<Map> selectTaskGanttByProjectId(@Param("projectId") String  projectId);

2、前端代码
