我想将 spring boot v2.1.9 升级到 2.2.0。但是升级后我得到了一些例外，它说 spring fox 使用的是旧版本的 spring-plugin-core。
有没有其他替代解决方案，或者我需要放弃 springfox 插件吗？

APPLICATION FAILED TO START

Description:
An attempt was made to call a method that does not exist. The attempt was made from the following location:
springfox.documentation.spring.web.plugins.DocumentationPluginsManager.createContextBuilder(DocumentationPluginsManager.java:152)
The following method did not exist:
org.springframework.plugin.core.PluginRegistry.getPluginFor(Ljava/lang/Object;Lorg/springframework/plugin/core/Plugin;)Lorg/springframework/plugin/core/Plugin;
The method's class, org.springframework.plugin.core.PluginRegistry, is available from the following locations:
jar:file:/C:/Users/regosa/.m2/repository/org/springframework/plugin/spring-plugin-core/2.0.0.RELEASE/spring-plugin-core-2.0.0.RELEASE.jar!/org/springframework/plugin/core/PluginRegistry.class
It was loaded from the following location:
file:/C:/Users/regosa/.m2/repository/org/springframework/plugin/spring-plugin-core/2.0.0.RELEASE/spring-plugin-core-2.0.0.RELEASE.jar
Action:
Correct the classpath of your application so that it contains a single, …Map<XMLGregorianCalendar, String> SortedByTimeForJourney = new HashMap<XMLGregorianCalendar, String>();
我必须按键（XMLGregorianCalendar）对其进行排序。我试过了
SortedByTimeForJourney.entrySet().stream().sorted(Map.Entry.<XMLGregorianCalendar, String>comparingByKey()).collect(Collectors.toMap(Map.Entry::getKey, Map.Entry::getValue, (e1, e2) -> e2, LinkedHashMap::new));
但它显示类型参数'javax.xml.datatype.XMLGregorianCalendar'的边界不完整；应该实现'java.lang.Comparable'
我也尝试通过将其保存在LinkedHashMap中并使用Collections.util方法来执行此操作，但是无法执行。
有人请帮助我。
