el表达式获取session值的代码

el表达式获取session值的代码是什么？这个问题就由星辉小编来为大家解答。

<script type="text/javascript">
    var usernameC = ${sessionScope.SESSION_USER_PROFILE.accountId};
    var caseId = "${caseId}";
    var taskId = "${taskId}";
    var uuid = "${uuid}";
</script>

后台控制层代码：

    @GetMapping(value = {URI_FILE_CASE_PANEL_AUDI, URI_FILE_CASE_PANEL_AUDI_HTM})
    public ModelAndView indexFile(@RequestParam(value = "caseId", required = false) Long caseId,
                                  @RequestParam(value = "taskId", required = false) String taskId,
                                  @RequestParam(value = "uuid", required = false) String uuid) {
        LOGGER.info("enter file case audit panel,caseId:{},taskId:{}", caseId, taskId);
        ModelMap map = new ModelMap();
        map.put("caseId", caseId);
        map.put("taskId", taskId);
        map.put("uuid", uuid);
        return new ModelAndView(FWD_FILE_CASE_PANEL_FILE_CASE, map);
    }
