对于最新的稳定版本,请使用 Spring Framework 6.2.0spring-doc.cadn.net.cn

配置全局日期和时间格式

默认情况下,日期和时间字段未使用@DateTimeFormat从 strings 结合使用DateFormat.SHORT风格。如果您愿意,可以通过以下方式更改此设置 定义您自己的全局格式。spring-doc.cadn.net.cn

为此,请确保 Spring 不注册默认格式化程序。相反,请注册 格式化程序:spring-doc.cadn.net.cn

例如,以下 Java 配置注册了一个全局yyyyMMdd格式:spring-doc.cadn.net.cn

@Configuration
public class AppConfig {

	@Bean
	public FormattingConversionService conversionService() {

		// Use the DefaultFormattingConversionService but do not register defaults
		DefaultFormattingConversionService conversionService =
			new DefaultFormattingConversionService(false);

		// Ensure @NumberFormat is still supported
		conversionService.addFormatterForFieldAnnotation(
			new NumberFormatAnnotationFormatterFactory());

		// Register JSR-310 date conversion with a specific global format
		DateTimeFormatterRegistrar dateTimeRegistrar = new DateTimeFormatterRegistrar();
		dateTimeRegistrar.setDateFormatter(DateTimeFormatter.ofPattern("yyyyMMdd"));
		dateTimeRegistrar.registerFormatters(conversionService);

		// Register date conversion with a specific global format
		DateFormatterRegistrar dateRegistrar = new DateFormatterRegistrar();
		dateRegistrar.setFormatter(new DateFormatter("yyyyMMdd"));
		dateRegistrar.registerFormatters(conversionService);

		return conversionService;
	}
}

如果您更喜欢基于 XML 的配置,可以使用FormattingConversionServiceFactoryBean.以下示例显示了如何执行此作:spring-doc.cadn.net.cn

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="
		http://www.springframework.org/schema/beans
		https://www.springframework.org/schema/beans/spring-beans.xsd">

	<bean id="conversionService" class="org.springframework.format.support.FormattingConversionServiceFactoryBean">
		<property name="registerDefaultFormatters" value="false" />
		<property name="formatters">
			<set>
				<bean class="org.springframework.format.number.NumberFormatAnnotationFormatterFactory" />
			</set>
		</property>
		<property name="formatterRegistrars">
			<set>
				<bean class="org.springframework.format.datetime.standard.DateTimeFormatterRegistrar">
					<property name="dateFormatter">
						<bean class="org.springframework.format.datetime.standard.DateTimeFormatterFactoryBean">
							<property name="pattern" value="yyyyMMdd"/>
						</bean>
					</property>
				</bean>
			</set>
		</property>
	</bean>
</beans>

请注意,在 Web 中配置日期和时间格式时,还需要注意一些额外的注意事项 应用。请参阅 WebMVC 转换和格式化WebFlux 转换和格式化spring-doc.cadn.net.cn
