Java 在对象列表中迭代的Thymeleaf显示为空

Java 在对象列表中迭代的Thymeleaf显示为空,java,html,spring-mvc,jsp,thymeleaf,Java,Html,Spring Mvc,Jsp,Thymeleaf,我试图使用SpringMVC遍历通过ModelMap传递的对象。但是,在浏览器上测试时,文本显示为空白。例如: test.jsp: <!DOCTYPE html> <html> <body> Hello ${test} <tr th:each="user,iterStat : ${testList}"> <td th:text="${user.id}" /> <td th:text="${user.name}

我试图使用SpringMVC遍历通过ModelMap传递的对象。但是,在浏览器上测试时,文本显示为空白。例如:

test.jsp:

<!DOCTYPE html>
<html>
<body>
Hello ${test}  

<tr th:each="user,iterStat : ${testList}">
    <td th:text="${user.id}" />
    <td th:text="${user.name}" />
</tr>
</body>
</html>

这里有什么问题?

您的模板名是
.jsp
,但您似乎在使用Thymeleaf(这是我的建议)。也许你想把它命名为
.html
?@chrylis啊,是的。我真是太愚蠢了。文件名应为.html。决定从JSP移植到Thymeleaf,但没有重命名文件。
@GetMapping("/test")
