使用@DateTimeFormat 注解有两种做法,如上面代码所示。 示例说明: 第一种是按照ISO国际标准的日期时间格式解析参数中的日期时间的,具体格式为此枚举变量: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 /** * Common ISO date time format patterns. ...
```java public class User { @DateTimeFormat(pattern = "yyyy-MM-dd")private Date birthday;// ...} ```在上述代码中，`birthday`属性上使用了`@DateTimeFormat(pattern = "yyyy-MM-dd")`注解，指明了日期时间的格式为"yyyy-MM-dd"。这样，在接受用户请求时，Spring就会根据这个格式将请求参数转换成`...
