SpringMVC 设置全局DateTime json返回格式

对部份返回DateTime的项目，只需要在指定属性上添加@JsonSerialize 使用自定义的json转换格式便可自定义返回DateTime格式

<!-- 采取SpringMVC自带的JSON转换工具，支持@ResponseBody注解 --> <bean class=" org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter"> <property name="messageConverters"> <list> <ref bean="mappingJacksonHttpMessageConverter" /> </list> </property> </bean> <!-- 避免IE履行AJAX时,返回JSON出现下载文件 --> <bean id="mappingJacksonHttpMessageConverter" class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter"> <property name="supportedMediaTypes"> <list> <value>application/json;charset=UTF⑻</value> <value>text/html;charset=UTF⑻</value> </list> </property> <property name="objectMapper"> <bean class="com.cml.mvc.framework.converter.DateTimeConverter"></bean> </property> </bean>
