SpringBoot整合FreeMarker

简介

SpringBoot建议我们使用模板引擎，不建议使用JSP。 模板引擎：可以实现动态页面静态化 常见的模板引擎技术有：velocity、Thymeleaf、Freemarker

示例 第一步：创建Maven项目，添加如下依赖

    org.springframework.boot
    spring-boot-starter-web


    org.springframework.boot
    spring-boot-starter-freemarker

第二步：修改application.yml：

spring:
  freemarker:
    suffix: .ftl

第三步：在resources/templates目录下创建模板文件fm.ftl：

• fm.ftl

Freemarker页面
${name}  ---   ${age}

• demo.ftl

${k}

    ${item}


${array[1]}

${dept}
${dept.dname}


${list[2]}

    ${item}



${deptList[1].dname}

   ${dept_index} ${dept.dname}




    ${k} ${map[k]}  ${map[k].deptno} 

第四步：创建Controller：

@Controller
public class TestController {

    @RequestMapping("/fun")
    public String fun(Model model){
        model.addAttribute("name","zhangsan");
        model.addAttribute("age",18);
        return "fm";
    }
    @RequestMapping("/fun1")
    public ModelAndView fun1(ModelAndView mav){
        mav.setViewName("demo");
        mav.addObject("k","asdf");

        mav.addObject("array",new int[]{11,22,33,44});

        mav.addObject("dept",new Dept(10,"sales","newYork"));
        List list = Arrays.asList("aa","bb","cc");
        mav.addObject("list",list);

        List deptList =  Arrays.asList(new Dept(10, "sales", "beijing"),
                new Dept(10, "research", "guangzhou"),
                new Dept(10, "account", "hangzhou"),
                new Dept(10, "operation", "shanghai"));
        mav.addObject("deptList",deptList);

        Map map  = new HashMap();
        map.put("aa", new Dept(10, "sales", "beijing"));
        map.put("bb",new Dept(20, "research", "guangzhou"));
        map.put("cc",new Dept(30, "account", "hangzhou"));
        map.put("dd",new Dept(40, "operation", "shanghai"));

        mav.addObject("map",map);

        System.out.println("****");
        return mav;
    }
}

结果：
