1、模板包含
1.1、同一个页面
此处是模版
1.2、同一个页面带参数
...
1.3、模板定义与调用 在不同页面
定义模板 footer.html，示例如下：
© 2016 CodeApe.cn基于ID属性的模板
调用文件，示例如下：
基于DOM选择器的模板引用，调用格式：th:include="templatename::domselector"
templatename是要引入页面的路劲加上去掉后缀的名称，例如footer.html页面建立在/WEB-INF/templates/footer.html，所以templatename为footer;domselector就是dom选择器，即为th:fragment中的值，或是选择id
2、页面控制语法
1、IF语法
此处是使用spring security的前提下，判断当前用户使用拥有 admin权限。
2、日期格式、组件提取等
${#dates.format(date)}${#dates.arrayFormat(datesArray)}${#dates.listFormat(datesList)}${#dates.setFormat(datesSet)}${#dates.format(date, 'dd/MMM/yyyy HH:mm')}${#dates.arrayFormat(datesArray, 'dd/MMM/yyyy HH:mm')}${#dates.listFormat(datesList, 'dd/MMM/yyyy HH:mm')}${#dates.setFormat(datesSet, 'dd/MMM/yyyy HH:mm')}${#dates.day(date)}${#dates.month(date)}${#dates.monthName(date)}${#dates.monthNameShort(date)}${#dates.year(date)}${#dates.dayOfWeek(date)}${#dates.dayOfWeekName(date)}${#dates.dayOfWeekNameShort(date)}${#dates.hour(date)}${#dates.minute(date)}${#dates.second(date)}${#dates.millisecond(date)}${#dates.create(year,month,day)}${#dates.create(year,month,day,hour,minute)}${#dates.create(year,month,day,hour,minute,second)}${#dates.create(year,month,day,hour,minute,second,millisecond)}${#dates.createNow()}${#dates.createToday()} 3、日历
