Infinispan缓存商店

Question

我想使用Infinispan缓存存储而不是LevelDb缓存存储。

下面是我的配置：

<infinispan
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   xsi:schemaLocation="urn:infinispan:config:6.0 http://www.infinispan.org/schemas/infinispan-config-6.0.xsd
                       urn:infinispan:config:jdbc:6.0 http://www.infinispan.org/schemas/infinispan-cachestore-jdbc-config-6.0.xsd"
   xmlns="urn:infinispan:config:6.0"
   xmlns:jdbc="urn:infinispan:config:jdbc:6.0" >
    <global>
        <globalJmxStatistics enabled="false" allowDuplicateDomains="true"/>
    </global>

    <!-- Define the cache loaders (i.e., cache stores). Passivation is false
     because we want *all* data to be persisted, not just what doesn't fit
     into memory. -->
    <persistence>
        <mixedKeyedJdbcStore fetchPersistentState="false" ignoreModifications="false" purgeOnStartup="false">
            <simpleConnection connectionUrl="jdbc:postgresql://localhost:5432/infinispan_binary_based" driverClass="org.postgresql.Driver" username="postgres" password="postgres"/>
            <stringKeyedTable prefix="ISPN_MIXED_STR_TABLE" createOnStart="true" dropOnExit="true">
                <idColumn name="ID_COLUMN" type="VARCHAR(255)" />
                <dataColumn name="DATA_COLUMN" type="BINARY" />
                <timestampColumn name="TIMESTAMP_COLUMN" type="BIGINT" />
            </stringKeyedTable>
            <binaryKeyedTable prefix="ISPN_MIXED_BINARY_TABLE" createOnStart="true" dropOnExit="true">
                <idColumn name="ID_COLUMN" type="VARCHAR(255)" />
                <dataColumn name="DATA_COLUMN" type="BINARY" />
                <timestampColumn name="TIMESTAMP_COLUMN" type="BIGINT" />
            </binaryKeyedTable>
        </mixedKeyedJdbcStore>
    </persistence>
</namedCache>

​

但我一直有个例外：

Message: Unexpected element '{urn:infinispan:config:jdbc:6.0}mixedKeyedJdbcStore'  
  at org.infinispan.configuration.parsing.ParserRegistry.parseElement(ParserRegistry.java:139) [infinispan-core-6.0.2.Final.jar:6.0.2.Final]  
  at org.infinispan.configuration.parsing.XMLExtendedStreamReaderImpl.handleAny(XMLExtendedStreamReaderImpl.java:37) [infinispan-core-6.0.2.Final.jar:6.0.2.Final]  
  at org.infinispan.configuration.parsing.Parser60.parsePersistence(Parser60.java:558) [infinispan-core-6.0.2.Final.jar:6.0.2.Final] 

我从依赖项中删除了leveldb缓存存储jar，并将其替换为jdbc缓存存储jar。

你能告诉我我错过了什么吗？请帮帮忙？

提前谢谢你。

您正在声明一个名为jdbc的命名空间，但不使用它。您需要在mixedKeyedJdbcStore中的所有标记前加上jdbc:，或者使用默认名称空间，如下所示：

<infinispan
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="urn:infinispan:config:6.0 http://www.infinispan.org/schemas/infinispan-config-6.0.xsd
                   urn:infinispan:config:jdbc:6.0 http://www.infinispan.org/schemas/infinispan-cachestore-jdbc-config-6.0.xsd"
    xmlns="urn:infinispan:config:6.0"
    xmlns:jdbc="urn:infinispan:config:jdbc:6.0" >
<global>
    <globalJmxStatistics enabled="false" allowDuplicateDomains="true"/>
</global>

<!-- Define the cache loaders (i.e., cache stores). Passivation is false
 because we want *all* data to be persisted, not just what doesn't fit
 into memory. -->
<namedCache name="testCache">
    <persistence>
        <mixedKeyedJdbcStore xmlns="urn:infinispan:config:jdbc:6.0" fetchPersistentState="false" ignoreModifications="false" purgeOnStartup="false">
            <simpleConnection connectionUrl="jdbc:postgresql://localhost:5432/infinispan_binary_based" driverClass="org.postgresql.Driver" username="postgres" password="postgres"/>
            <stringKeyedTable prefix="ISPN_MIXED_STR_TABLE" createOnStart="true" dropOnExit="true">
                <idColumn name="ID_COLUMN" type="VARCHAR(255)" />
                <dataColumn name="DATA_COLUMN" type="BINARY" />
                <timestampColumn name="TIMESTAMP_COLUMN" type="BIGINT" />
            </stringKeyedTable>
            <binaryKeyedTable prefix="ISPN_MIXED_BINARY_TABLE" createOnStart="true" dropOnExit="true">
                <idColumn name="ID_COLUMN" type="VARCHAR(255)" />
                <dataColumn name="DATA_COLUMN" type="BINARY" />
                <timestampColumn name="TIMESTAMP_COLUMN" type="BIGINT" />
            </binaryKeyedTable>
        </mixedKeyedJdbcStore>
    </persistence>
</namedCache>

您的配置也缺少了一个启动的namedCache标记，但我认为这是一个复制错误，否则错误消息将是不同的。
