package com.yq.springboot01.controller;

@Controller
@RequestMapping("/freemarker")
public class RoleController {
@RequestMapping("/list")
public ModelAndView list(){
System.out.println("这是list");
ModelAndView mv = new ModelAndView();
mv.setViewName("list");
mv.addObject("name","张三");
mv.addObject("sex","gay");
List<Role> list=new ArrayList<>();
list.add(new Role("1","主管"));
list.add(new Role("2","会计"));
list.add(new Role("3","库管"));
mv.addObject("roles",list);
return mv;
}
}
注意点：
1、application.yml中可以配置模板存放位置的根路径、以及静态资源文件存放位置的根路径
2、${springMacroRequestContext.contextPath}：SpringBoot中获取项目名
3、不推荐使用全局变量。即便它们属于不同的命名空间， 全局变量也被所有模板共享，因为它们是被 import进来的。
4、freemarker模板也可以像jsp那样设置根路径
