在Thymeleaf模板中为Out Date而不是日期/时间

当我在

Thymeleaf

模板中输出生日时，它会打印日期/时间：

1962-04-18 00:00:00.0

如何仅输出日期

这是我目前得到的：

pom.xml

org.springframework.boot
弹簧启动装置
org.thymeleaf
百里香
3.0.11.1发布
org.thymeleaf
百里香
3.0.11.1发布
org.thymeleaf.extras
thymeleaf-extras-Java8时间
3.0.4.1发布

Thymeleaf模板：

User.java中的变量

@DateTimeFormat（pattern=“yyyy-MM-dd”）
@列（name=“出生日期”）
私人生日；

当我尝试查看页面时，我得到：

Whitelabel Error Page

This application has no explicit mapping for /error, so you are seeing this as a fallback.

这将添加与标准方言中类似的#temporals对象，允许从Thymeleaf模板格式化和创建时态对象

为了测试新类和旧类的处理，创建以下变量并将其作为模型对象添加到控制器类：

model.addAttribute("standardDate", new Date());
model.addAttribute("localDateTime", LocalDateTime.now());
model.addAttribute("localDate", LocalDate.now());
model.addAttribute("timestamp", Instant.now());

谢谢我试过了，但得到了这个

，原因是：org.thymeleaf.exceptions.TemplateProcessingException:Exception评估SpringEL表达式：“#temporals.format（tempUser.birthDate，'dd/MM/yyyyy'）”（模板：“用户/列表用户”-第43行，第9列）

请注意，我最初使用

日期

时，我应该使用

本地日期。
