springboot中前端$取值出错

Question

springboot项目从数据库中取数据，html动态获取值，即数据库中有几条数据前端展示几条数据
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“ 报红
项目可以运行，但是进不去index
报错如下：

Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed; nested exception is org.thymeleaf.exceptions.TemplateInputException: An error happened during template parsing (template: "class path resource [templates/index.html]")] with root cause

日志上显示的就是前端页面的问题

Could not parse as expression: "@{${info.url}" (template: "index" - line 182, col 92)

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,id
        from information
        where id = '1'
    </select>

你好，是thymeleaf的循环语法使用错误：

thymeleaf正确的循环使用方法如下：
