Hazelcast集成Spring，解析hazelcast定义出错

在Spring中定义Hazelcast配置：

 

<beans xmlns="http://www.springframework.org/schema/beans"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"
 xmlns:hz="http://www.hazelcast.com/schema/spring"
 xsi:schemaLocation="http://www.springframework.org/schema/beans
                http://www.springframework.org/schema/beans/spring-beans.xsd
                http://www.springframework.org/schema/context
                http://www.springframework.org/schema/context/spring-context.xsd
                http://www.hazelcast.com/schema/spring
                http://www.hazelcast.com/schema/spring/hazelcast-spring.xsd">

 <context:annotation-config />

 <hz:hazelcast id="instance">
  <hz:config>
   <hz:network port="5701" port-auto-increment="true">
    <hz:join>
     <hz:multicast enabled="true" 
      multicast-group="224.2.2.3" 
      multicast-port="54327" 
      multicast-time-to-live="32" 
      multicast-timeout-seconds="2" />
    </hz:join>
   </hz:network>
   
   <hz:group name="pushcoregroup" password="password" />
  
    
  </hz:config>
 </hz:hazelcast>

</beans>

 

 

启动时，程序报错：

Caused by: org.xml.sax.SAXParseException; lineNumber: 25; columnNumber: 57; cvc-complex-type.2.4.a: 发现了以元素 'hz:group' 开头的无效内容。应以 '{"http://www.hazelcast.com/schema/spring":partition-group, "http://www.hazelcast.com/schema/spring":executor-service, "http://www.hazelcast.com/schema/spring":queue, "http://www.hazelcast.com/schema/spring":map, "http://www.hazelcast.com/schema/spring":cache, "http://www.hazelcast.com/schema/spring":multimap, "http://www.hazelcast.com/schema/spring":list, "http://www.hazelcast.com/schema/spring":set, "http://www.hazelcast.com/schema/spring":topic, "http://www.hazelcast.com/schema/spring":jobtracker, "http://www.hazelcast.com/schema/spring":replicatedmap, "http://www.hazelcast.com/schema/spring":listeners, "http://www.hazelcast.com/schema/spring":serialization, "http://www.hazelcast.com/schema/spring":security, "http://www.hazelcast.com/schema/spring":member-attributes, "http://www.hazelcast.com/schema/spring":services}' 之一开头。

通过排查后，发现http://hazelcast.com/schema/spring/hazelcast-spring-3.4.xsd中定义了元素出现的顺序，

 

<xs:element name="config">
<xs:complexType>
<xs:complexContent>
<xs:extension base="hazelcast-bean">
<xs:sequence>
<xs:element name="spring-aware" type="spring-aware" minOccurs="0" maxOccurs="1"/>
<xs:element name="instance-name" type="xs:string" minOccurs="0" maxOccurs="1"/>
<xs:element name="group" type="group" minOccurs="0" maxOccurs="1"/>
<xs:element name="license-key" type="xs:string" minOccurs="0" maxOccurs="1"/>

其中xs:sequence指示器规定了各个元素出现的顺序，要求group出现在network的前面，于是，把配置改成这样：

<beans xmlns="http://www.springframework.org/schema/beans"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"
 xmlns:hz="http://www.hazelcast.com/schema/spring"
 xsi:schemaLocation="http://www.springframework.org/schema/beans
                http://www.springframework.org/schema/beans/spring-beans.xsd
                http://www.springframework.org/schema/context
                http://www.springframework.org/schema/context/spring-context.xsd
                http://www.hazelcast.com/schema/spring
                http://www.hazelcast.com/schema/spring/hazelcast-spring.xsd">

 <context:annotation-config />

 <hz:hazelcast id="instance">
  <hz:config>
   <hz:group name="pushcoregroup" password="password" />
  
   <hz:network port="5701" port-auto-increment="true">
    <hz:join>
     <hz:multicast enabled="true" 
      multicast-group="224.2.2.3" 
      multicast-port="54327" 
      multicast-time-to-live="32" 
      multicast-timeout-seconds="2" />
    </hz:join>
   </hz:network>
   
   
  
    
  </hz:config>
 </hz:hazelcast>

</beans>
