java - 无法使用 DateTimeFormat 注释让 Spring MVC 解析日期时间

Question

我想在休息服务中使用路径参数作为完整的 ISO 时间戳。

http://domain:8080/ctx/someObj/2000-10-31 01:30:00.000-05:00

我之前打开了 mvc:annotation driven，但后来将其关闭，因此我可以在 DefaultAnnotationHandlerMapping 上将“useDefaultSuffixPattern”设置为 false。

Controller 代码

@RequestMapping(value = "/lwc/{userMidnightTime}", method = RequestMethod.GET)
@ResponseBody
public List<ProgramSnippetView> getLiveWebcastsWithin24HoursOfTime(@PathVariable(value = "userMidnightTime") @DateTimeFormat(iso= DATE_TIME) Date userMidnightTime) {
    Calendar cal = new GregorianCalendar();
    cal.setTime(userMidnightTime);
    cal.add(Calendar.HOUR, 24);
    Date endTime = cal.getTime();
    return programService.getLiveWebcastSnippetsWithProductionDateInRange(userMidnightTime, endTime);
}

我收到以下错误。我可以看到框架最终使用正确的字符串调用已弃用的 Date.parse() 方法，而不是使用 joda time 来完成工作。

112977 [http-apr-8080-exec-7] DEBUG org.springframework.beans.BeanUtils - No property       editor [java.util.DateEditor] found for type java.util.Date according to 'Editor' suffix convention
117225 [http-apr-8080-exec-7] DEBUG org.springframework.beans.TypeConverterDelegate - Construction via String failed for type [java.util.Date]
org.springframework.beans.BeanInstantiationException: Could not instantiate bean class [java.util.Date]: Constructor threw exception; nested exception is     java.lang.IllegalArgumentException

我希望 joda 解析完整的 ISO 日期，如 org.springframework.format.annotation.DateTimeFormat.java 注释文件中指定的那样:

/** 
     * The most common ISO DateTime Format <code>yyyy-MM-dd'T'hh:mm:ss.SSSZ</code> e.g. 2000-10-31 01:30:00.000-05:00.
     * The default if no annotation value is specified.
     */
    DATE_TIME,  .....

应用上下文配置

我看到的一个可能的问题是您没有向 handlerAdapter 注册 conversionService，您可以这样做:

<bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
    <property name="webBindingInitializer">
        <bean class="org.springframework.web.bind.support.ConfigurableWebBindingInitializer">
            <property name="conversionService" ref="conversionService"/>
            <property name="validator" ref="validator"/>
        </bean>
    </property>
