今天在访问Thymeleaf模板页面时，出现了下面的错误
Whitelabel Error Page
This application has no explicit mapping for /error, so you are seeing this as a fallback.

There was an unexpected error (type=Internal Server Error, status=500).
An error happened during template parsing (template: "class path resource [templates/list.html]" - line 13, col 4)
查看控制台日志并没有报错，再找到报错代码：
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:th="http://www.thymeleaf.org">
<head>
<meta charset="UTF-8">
<title th:text="${title}">Title</title>
</head>
<body>
<h1 th:text="${desc}">Hello Word!</h1>
<h2>-----------------------------</h2>
<p th:each="user:${users}"
th:text="${user.id}"
th:text="${user.userName}"
th:text="${user.date}">
</p>
</body>
在看看User类的属性
@Entity
@Table(name = "user")
public class User {
@Id
@GeneratedValue
private Long id;
private String userName;
@DateTimeFormat(pattern = "yyyy-MM-dd HH:mm:ss")
private Date date;
这才发现错误原因：Users类的属性id,userName,date时私有属性，不能直接调用
解决办法：
调用get方法获取属性"
<p th:each="user:${users}"
th:text="${user.getId()}"
th:text="${user.getUserName()}"
th:text="${user.getDate()}">
</p>
