Spring Rest JSON日期格式

spring-restcontroller jackson java

Michael user5835524 · 技术社区 · 9 年前

我知道,这里有很多来自Spring MVC的客户端JSON日期格式的例子,但在我的例子中,除了一个使用复合合同的特定案例之外,一切都很好。

问题是,在客户端,JSON响应端 curObj 日期 currencyOpenedDate 收到 字符串格式 ,同时 depObj.subdivisionClosedDate 日期以时间戳格式指定。您可以在问题底部找到的回答屏幕。

curObj.currencyOpenedDate 时间戳格式?

<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"/>

混合成的

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;
    }

}

货币和细分DTO非常简单,没有任何注释和日期属性。这两种情况下的初始化如下:

    Date openDate = null;

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

按如下方式配置对象映射器;

@Autowired
private ObjectMapper objectMapper;

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