Question

我在对象数组内传递日期参数作为请求参数，同时使用"gatherOnce"对我的spring容器进行rest调用。

代码如下：

RestTemplate

当请求到达我的服务器时，我收到的日期已久。如何获取日期作为日期？为什么会持续这么长时间？

下面是我的dispatcher-servlet.xml

HttpEntity<SimplePipeServiceRequest> request = new HttpEntity<>(new Object[]{new Date(), 1}, headers);
response = template.postForEntity(uri1, request, String.class);

以及以下是我在进行其余调用的地方的dispatcher-servlet.xml

<context:component-scan base-package="com.altra.aligne.controller"></context:component-scan>

<mvc:annotation-driven conversion-service="conversionService">
    <mvc:message-converters register-defaults="true">
        <bean class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
            <property name="objectMapper">
                <bean class="com.altra.middleware.spring.CustomObjectMapper"></bean>
            </property>
        </bean>
    </mvc:message-converters>
</mvc:annotation-driven>

<!-- RequestMappingHandlerMapping.setUseSuffixPatternMatch(boolean useSuffixPatternMatch) = Whether to use suffix pattern match (".*") 
when matching patterns to requests. -->
<bean class="com.altra.middleware.spring.ControllerBeanPostProcessor" />

<bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver" />

<bean id="conversionService" class="org.springframework.context.support.ConversionServiceFactoryBean">
  <property name="converters">
    <list>
        <bean class="com.altra.middleware.spring.GenericDTOConverter"/>
        <bean class="com.altra.middleware.spring.StringToDateConverter"/>
    </list>
  </property>
</bean>

任何人都可以解释将日期转换为长日期的位置和方式，如果我想避免将日期转换为长日期，以及是否可以从长日期再次获得相等的日期？

我不了解杰克逊在Spring中的实际工作方式。

        all by itself, it will handle requests it should not handle, e.g. encoding strings.  So we need to add the

        <!--<bean class="org.springframework.http.converter.xml.MarshallingHttpMessageConverter"/>-->
    </mvc:message-converters>
</mvc:annotation-driven>

不过，执行 post 后，两个序列化程序都不会被调用。

谢谢！

您需要自定义ObjectMapper：

ObjectMapper mapper = new ObjectMapper();
mapper.setDateFormat(DateFormat.getDateInstance());
mapper.setTimeZone(TimeZone.getTimeZone("UTC"));

但是，如果可以的话，使用Java 8 Time软件包会更安全。
