springboot中$取值报错

springboot项目从数据库中取数据，html动态获取值，但是html页面中$取值一致报红，即下html页面中${info_list}里面的info_list

这种问题处在什么地方？

html页面

                            <li th:each="info = ${info_list}">
                                <div >< th:src="@{${info.url}" alt="emptyimg" /></div>
                                <div>
                                    <h6 th:text="${info.title}"></h6>
                                    <p th:text="${info.profile}"></p>
                                    <span " th:text="${info.location}"> </span>
                            </li>

controller代码

    @RequestMapping("/toindex")
    public String toIndex(Model model) {
        List<Information> info_list = informationDao.queryInfo();
        model.addAttribute("info_list", info_list);
        return "index";
    }

dao代码

@Mapper
public interface InformationDao {
    List<Information> queryInfo();
}

mapper.xml

<select id="queryInfo" resultMap="InformationMap">
        select
        title,profile,location
        from information
        where id = 'index'
    </select>

你的改成这样

                            <li th:each="info:${info_list}">
                                <div >< th:src="@{${info.url}" alt="emptyimg" /></div>
                                <div>
                                    <h6 th:text="${info.title}"></h6>
                                    <p th:text="${info.profile}"></p>
                                    <span " th:text="${info.location}"> </span>
                            </li>

遍历列表这样写


<!DOCTYPE html>
<html lang="en" xmlns:th="http://www.thymeleaf.org">
<head>
    <meta charset="UTF-8">
    <title>循环遍历Array数组</title>
</head>
<body>
    <h1>循环遍历Array数组(使用方法和list一样)</h1>
    <div th:each="user:${users}">
        <span th:text="${userStat.index}"></span>
        <span th:text="${userStat.count}"></span>
        <span th:text="${user.id}"></span>
        <span th:text="${user.name}"></span>
        <span th:text="${user.phone}"></span>
        <span th:text="${user.address}"></span>
    </div>
</body>
</html>
