java spring boot- freemarker 配置 yml使用流程

1、pom.xml 加入maven 依赖

<!-- 引入 freemarker 模板依赖 -->
<dependency>
   <groupId>org.springframework.boot</groupId>
   <artifactId>spring-boot-starter-freemarker</artifactId>
</dependency>

2、执行更新

3、在application.yml 中添加 feemarker 配置

spring:
  freemarker:
    allow-request-override: false
    cache: true
    check-template-location: true
    charset: UTF-8
    suffix: .html
    templateEncoding: UTF-8
    templateLoaderPath: classpath:/templates/
    content-type: text/html
    expose-request-attributes: false
    expose-session-attributes: false
    expose-spring-macro-helpers: false
4、控制器代码

@GetMapping(value = "/my")
    public ModelAndView my(ModelMap modelMap){
        ModelAndView mv = new ModelAndView("pay");
        modelMap.addAttribute("name","pengxingjiang");
        mv.addObject("address","四川-宜宾");
        HashMap<String,String> userInfo = new HashMap<>();
        userInfo.put("name","111");
        userInfo.put("tel","18888888888");
        mv.addObject("userInfo",userInfo);
        return mv;
}


5、视图文件代码

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
    ${name}
    ${address}
========
  ${userInfo.name}
  ${userInfo.tel}
</body>
</html>

6、list 循环的使用

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
    <#list list as item>
        <p>${item.name}-${item.tel}</p>
    </#list>
</body>
</html>

@GetMapping(value = "/my")
    public ModelAndView my(ModelMap modelMap){
        ModelAndView mv = new ModelAndView("pay");
        HashMap<String,String> userInfo = new HashMap<>();
        userInfo.put("name","我的名字");
        userInfo.put("tel","18288888888");
        mv.addObject("userInfo",userInfo);
        List<HashMap> list = new ArrayList<>();
        list.add(userInfo);
        list.add(userInfo);
        list.add(userInfo);
        list.add(userInfo);
        mv.addObject("list",list);
        return mv;
}
