解決報錯DEFAULT_INCOMPATIBLE_IMPROVEMENTS

freemarker整合springMVC報錯如下：
警告: Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'freemarkerConfig' defined in class path resource [springmvc.xml]: Invocation of init method failed; nested exception is java.lang.NoSuchFieldError: DEFAULT_INCOMPATIBLE_IMPROVEMENTS

解決方式，把原有的freemarker版本換成最新版；
