这篇文章主要介绍“怎么用springboot+thymeleaf+mybatis实现甘特图”，在日常操作中，相信很多人在怎么用springboot+thymeleaf+mybatis实现甘特图问题上存在疑惑，小编查阅了各式资料，整理出简单好用的操作方法，希望对大家解答”怎么用springboot+thymeleaf+mybatis实现甘特图”的疑惑有所帮助！接下来，请跟着小编一起来学习吧！
首先我们要明白：这个甘特图需要哪些动态数据。
（1）需要：ID，tName，number，计划开始时间，开始时间，计划结束时间，结束时间，项目负责人，参与人，知情人ID，计划时长（可以计算得出的，不必在数据库中）；前置任务；项目进度，该任务属于哪个任务
（2）然后利用easycode插件生成实体类，映射类，服务类，ontCroller等
(3)利用bootstrap框架做出甘特图的样式，写好JS。

"0" + (date.getMonth() + 1) : (date.getMonth() + 1); var day = date.getDate() <= 9 ? "0" + date.getDate() : date .getDate(); return year + "/" + month + "/" + day; }</script></html>(4)在Controller层中利用Http请求传参
@RequestMapping(value = "/gantee",method = RequestMethod.GET) public String gantee(Model model) throws JSONException { Renwu renwu = renwuService.queryById(new Integer("1")); Map jsonData = new HashMap(); List<Map> jsonArray = new ArrayList<>(); Map jsonObject = new HashMap(); Integer id = renwu.getProjectid(); Integer pid = renwu.getPid(); String projectName = renwu.getProjectname(); String projectCode = renwu.getProjectcode(); SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy/MM/dd"); Date planStartDate = renwu.getPlanstartat(); Date planEndDate = renwu.getPlanendat(); Date startDate = renwu.getStartat(); Date endDate = renwu.getEndat(); String planStartStr = dateFormat.format(planStartDate); String planEndStr = dateFormat.format(planEndDate); String startStr = dateFormat.format(startDate); String endStr = dateFormat.format(endDate); String persent = renwu.getPersent(); String resps = renwu.getResps(); String actors = renwu.getActors(); String insiders = renwu.getInsiders(); Integer dur = renwu.getDur(); Integer before = renwu.getBefore(); jsonObject.put("id",id); jsonObject.put("pid",pid); jsonObject.put("projectName",projectName); jsonObject.put("projectCode",projectCode); jsonObject.put("planStartAt",planStartStr); jsonObject.put("planEndAt",planEndStr); jsonObject.put("startAt",startStr); jsonObject.put("endAt",endStr); jsonObject.put("persent",persent); jsonObject.put("resps",resps); jsonObject.put("actors",actors); jsonObject.put("insiders",insiders); jsonObject.put("dur",dur); jsonObject.put("before",new Object[]{before}); jsonArray.add(jsonObject); jsonData.put("data",jsonArray); model.addAttribute("lyhGanttuData",jsonData); return "ganttu"; }（5）直接启动SpringBoot项目即可。
这个是Springboot项目，自然也是可以转到SpringCloud的子项目中。
注意：HTML并不是我原创没我只是在其基础上改了一下JS。在这个开放的时代，我觉得大家应该把学到的东西开放出来，不管多好或是很差。
