错误消息如下:
There was an unexpected error (type=Internal Server Error, status=500). Exception parsing document: template="register", line 15 - column 3
如果我删除使用 th: 的表单，则它会正确显示页面。但通过表格我得到了错误。我在代码中看不到任何错误，希望有人能看一下。
注册.html:
<!DOCTYPE html>
<html lang="en" xmlns:th="http://www.thymeleaf.org">
<head>
<title>User Registration</title>
</head>
<body>
<h3>User Registration</h3>
<form action="#" th:action="@{/user/register}" th:object="${user}" method="post">

<input type="submit" value="Register">

用户.java:
package com.demo.spring.domain;
public class User {
String firstname;
String lastname;
String password;
public String getFirstname() {
return firstname;
}
public void setFirstname(String firstname) {
this.firstname = firstname;
}
public String getLastname() {
return lastname;
}
public void setLastname(String lastname) {
this.lastname = lastname;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
}
最佳答案
这是因为您错过了 <input> 的结束标记元素。
例如:使用这个
<input type="text" th:field="*{firstname}"/>
而不是
<input type="text" th:field="*{firstname}">
Thymeleaf只能处理有效的XML .它仅适用于格式良好的 XML，因此如果您想使用 HTML5模板模式您的 HTML 必须是格式良好的 XML。否则，您可以使用LEGACYHTML5模板
