SpringMVC项目如何全局格式化日期格式

Answer 1

spring的RequestMappingHandlerAdapter中的messageConverters就能够全局格式化日期格式

1. 配置spring-servlet
- 引入请求映射器
org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter
- 加入消息转化器
messageConverters
- 引入Json转化器
org.springframework.http.converter.json.MappingJackson2HttpMessageConverter
- 实现对象转化器
objectMapper
- 日期转换格式定义
dateFormat
2. 代码
<bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter">
<property name="webBindingInitializer">
<bean class="com.suixingpay.common.web.WebBindingInitializer">
<property name="conversionService">
<bean class="org.springframework.format.support.FormattingConversionServiceFactoryBean"></bean>
</property>
</bean>
</property>
<property name="messageConverters">
