echache3 XML解析问题

Question

出于某种原因，我无法将expiry元素添加到ehcache3配置xml中。没有expiry元素的 ，它工作正常。

<config xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance' 
    xmlns='http://www.ehcache.org/v3' 
    xmlns:jsr107='http://www.ehcache.org/v3/jsr107'> 

    <service> 
    <jsr107:defaults> 
     <jsr107:cache name="people" template="heap-cache"/> 
    </jsr107:defaults> 
    </service> 

    <cache-template name="heap-cache"> 
    <listeners> 
     <listener> 
      <class>org.terracotta.ehcache.EventLogger</class> 
      <event-firing-mode>ASYNCHRONOUS</event-firing-mode> 
      <event-ordering-mode>UNORDERED</event-ordering-mode> 
      <events-to-fire-on>CREATED</events-to-fire-on> 
      <events-to-fire-on>UPDATED</events-to-fire-on> 
      <events-to-fire-on>EXPIRED</events-to-fire-on> 
      <events-to-fire-on>REMOVED</events-to-fire-on> 
      <events-to-fire-on>EVICTED</events-to-fire-on> 
     </listener> 
    </listeners> 
    <expiry> 
     <ttl unit="seconds">10</ttl> 
    </expiry> 
    <resources> 
     <heap unit="entries">2000</heap> 
     <offheap unit="MB">100</offheap> <!-- unit of measure is case sensitive! --> 
    </resources> 
    </cache-template> 
</config> 

的错误信息是：

org.xml.sax.SAXParseException: cvc-complex-type.2.4.a: Invalid content was found starting with element 'expiry'. One of '{"http://www.ehcache.org/v3":heap, "http://www.ehcache.org/v3":resources, "http://www.ehcache.org/v3":heap-store-settings, "http://www.ehcache.org/v3":disk-store-settings, "http://www.ehcache.org/v3":service-configuration}' is expected. 

但看着这个XSD： http://www.ehcache.org/schema/ehcache-core.xsd 我看不出有什么毛病的标签，任何人有任何想法？

Answer 1

的Ehcache 3严格执行XSD，所以cache或cache-template内的元素必须以下列顺序：

1. key-type
2. value-type
3. expiry
4. eviction-advisor
5. loader-writer
6. listeners
7. resources OR heap
8. 更多...

与所有元素是可选的除上浆（地方7），其是在一个cache-template虽然可选的。

您必须添加xsi:schemaLocation和listeners配置后expiry

您的Ehcache配置的正确形式低于：
