github项目地址：https://github.com/H-Designer/SpringBoot
上一节总结的是：国际化语言的设定、拦截器设定https://www.cnblogs.com/zhaochunhui/p/11331976.html
这一节要总结的是：员工列表、多个页面的项目布局的提取
##7.员工页面的信息展示（跳转） 在dashboard.html界面： <!DOCTYPE html> <!-- saved from url=(0052)http://getbootstrap.com/docs/4.0/examples/dashboard/ --> <html lang="en" xmlns:th="http://www.thymeleaf.org"> <head>

EmployeeDao employeeDao; //查询所有的员工信息,返回到员工列表页面 @GetMapping("/emps") public String list(Model model){ Collection<Employee> employee = employeeDao.getAll(); //放在请求域中 model.addAttribute("emps",employee); //thymeleaf会自动进行拼接 //classpath:/tempaltes/xxx.html return "emp/list"; } } 然后根据return "emp/list";跳转到emp/list的html文件下，进行访问
##8.不同html文件相同内容的提取（例如表头和列表项相同，进行提取相同信息）： 头部以及左部的内容的提取 如果在多个界面之间用到多个相同的布局模块，然后就可以将这些提取为一个common.html页面进行存储，然后在每个界面进行相同模块的引用 可以在commons.bar.html进行模块的提取： <!DOCTYPE html> <html lang="en"

下一节要总结的是：页面列表选项的高亮设置、员工信息的添加页面设定（https://www.cnblogs.com/zhaochunhui/p/11332048.html）
