java - Spring Rest JSON 日期格式

Question

我知道，这里有很多来自 Spring MVC 客户端的 JSON 日期格式的示例，但在我的例子中，除了一个具有复合契约的特定情况之外，一切正常。

问题在于，在 curObj 的客户端 JSON 响应端，以字符串格式接收到日期 currencyOpenedDate，同时depObj.subdivisionClosedDate 日期中的时间以时间戳格式指定。 您可以在问题底部找到答复屏幕。

问题是如何接收时间戳格式的curObj.currencyOpenedDate？

Spring 配置

<context:component-scan base-package="ru.iteco.kursval.server.rest"/>
<context:annotation-config/>
<!-- Configures the @Controller programming model -->
<bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter">
    <property name="messageConverters">
        <list>
            <bean class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter"/>
        </list>
    </property>
</bean>
<!-- Total customization - see below for explanation. -->
<bean id="contentNegotiationManager" class="org.springframework.web.accept.ContentNegotiationManagerFactoryBean">
    <property name="favorPathExtension" value="false"/>
    <property name="favorParameter" value="true"/>
    <property name="parameterName" value="mediaType"/>
    <property name="ignoreAcceptHeader" value="true"/>
    <property name="useJaf" value="false"/>
    <property name="defaultContentType" value="application/json"/>

    <property name="mediaTypes">
        <map>
            <entry key="json" value="application/json"/>
            <entry key="xml" value="application/xml"/>
        </map>
    </property>
</bean>

<mvc:interceptors>
    <mvc:interceptor>
        <mvc:mapping path="/**"/>
        <bean:bean class="ru.iteco.kursval.server.rest.config.ApiInterceptor" autowire="constructor">
        </bean:bean>
    </mvc:interceptor>
</mvc:interceptors>

<!-- Make this available across all of Spring MVC -->
<mvc:annotation-driven content-negotiation-manager="contentNegotiationManager"/>

复合

public class RegionalBankBlockCurrencyDto implements Serializable {
    //.....
    private Long curId;
    /*----> here */ private CurrencyDto curObj;
    private Long depId;
    private SubdivisionDto depObj;

    // .... getters and setters

}

货币对象

public class CurrencyDto implements Serializable {

    private Date currencyOpenedDate;
    private Date currencyClosedDate;

    public Date getCurrencyOpenedDate() {
        return currencyOpenedDate;
    }

    public void setCurrencyOpenedDate(Date currencyOpenedDate) {
        this.currencyOpenedDate = currencyOpenedDate;
    }

    public Date getCurrencyClosedDate() {
        return currencyClosedDate;
    }

    public void setCurrencyClosedDate(Date currencyClosedDate) {
        this.currencyClosedDate = currencyClosedDate;
    }

}

货币和分割 DTO 很简单，没有任何注释，两种情况下的日期属性初始化如下所示:

    Date openDate = null;

    if (currency.getOpenDate() != null) {
        openDate = new Date(currency.getOpenDate().getTime());
    }

Answer 1

按如下方式配置您的对象映射器；

@Autowired
private ObjectMapper objectMapper;

objectMapper.configure(SerializationConfig.Feature.WRITE_DATES_AS_TIMESTAMPS, true);
