在后台获取Jmesa中被选中的行（check=true）-优快云博客

本文介绍了一种通过HTTP请求从数据库中批量删除研究案例的方法。使用了jmesa组件进行表格状态管理，并通过WorksheetState获取待删除记录。针对每条记录，通过其唯一标识解析并构造对应的实体对象，最后调用服务层接口完成删除操作。


/**
	 * To remove a AssayReturntypes 
	 * 
	 * @param request HttpServletRequest
	 * @param response HttpServletResponse
	 */
	@RequestMapping
	public void removeStudys(HttpServletRequest request, HttpServletResponse response) {

		WebContext webContext = new HttpServletRequestWebContext(request);
		WorksheetState state = new SessionWorksheetState("studysTable", webContext);
		Worksheet worksheet = state.retrieveWorksheet();
		Collection<WorksheetRow> rows = worksheet.getRows();
		List<Study> studys = new ArrayList<Study>();
		StringBuffer buffer = new StringBuffer();

		for (WorksheetRow row : rows) {
			String idStr = row.getUniqueProperty().getValue();
			Study study = new Study();
			if(!StringUtils.isEmpty(idStr) && StringUtils.isNumeric(idStr)) {
				study.setId(Integer.parseInt(idStr));
				studys.add(study);
			}
			buffer.append(idStr);
		}

		if (!studyService.removeStudy(studys)) {
			MessageUtils.outputJSONResult(buffer.toString(), response);
		}
	}
