java.lang.NoSuchFieldError : DEFAULT_INCOMPATIBLE_IMPROVEMENTS

Question

请任何人告诉我如何解决此错误，

我正在使用 spring-webmvc.3.2.17 和 freemarker.2.3.16

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'freemarkerConfig' defined in ServletContext resource [/WEB-INF/applicationContext.xml]: Invocation of init method failed; nested exception is java.lang.NoSuchFieldError: DEFAULT_INCOMPATIBLE_IMPROVEMENTS

这是我的 bean

<bean id="freemarkerConfig"
    class="org.springframework.web.servlet.view.freemarker.FreeMarkerConfigurer">
    <property name="templateLoaderPath" value="/" />
    <property name="defaultEncoding" value="UTF-8" />
    <property name="freemarkerSettings">
        <props>
            <prop key="date_format">dd MMM yyyy</prop>
            <prop key="datetime_format">yyyy-MM-dd HH:mm:ss</prop>
            <prop key="number_format">########</prop>
        </props>
    </property>
</bean>

spring-webmvc.3.2.17 需要 freemarker:2.3.20 或更高版本。
