找不到元素'ehcache'的声明

标签： java spring ehcache

我正在我的网络应用程序中实现url缓存。运行时我在ehcache.xml文件中有错误。我正在使用spring 2.5 jar文件。

ehcache.xml中

<?xml version="1.0" encoding="UTF-8"?>

<ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:noNamespaceSchemaLocation="ehcache.xsd" updateCheck="false"
    monitoring="autodetect" dynamicConfig="true" maxBytesLocalOnHeap="2m"
    maxBytesLocalOffHeap="2m" maxBytesLocalDisk="2m">


    <defaultCache eternal="false" maxElementsInMemory="1000"
        overflowToDisk="false" diskPersistent="false" timeToIdleSeconds="0"
        timeToLiveSeconds="600" memoryStoreEvictionPolicy="LRU" />

    <cache name="videoItemsCache" eternal="false"
        maxElementsInMemory="1000" timeToIdleSeconds="1200" timeToLiveSeconds="1200"
        overflowToDisk="false" diskPersistent="false"
        memoryStoreEvictionPolicy="LRU" />

</ehcache>

错误是：

请任何人帮助我。

的xsi：noNamespaceSchemaLocation =＆＃34; ehcache.xsd＆＃34;

此位置必须是绝对路径

像这样：... Location =＆＃34; classpath：/yourPathInProject/ehcache.xml"

在此之前，您需要从http://www.ehcache.org/ehcache.xsd下载ehcache.xml 并把它放在你的道路上。 对不起，我的英语很差。

尝试这样的事情，这是我在项目中使用的

<强>的applicationContext.xml 

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:aop="http://www.springframework.org/schema/aop"
       xmlns:ehcache="http://www.springmodules.org/schema/ehcache"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
       http://www.springmodules.org/schema/ehcache http://www.springmodules.org/schema/cache/springmodules-ehcache.xsd
       http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd">

    <ehcache:config configLocation="classpath:ehcache.xml" />

    <ehcache:proxy id="saleDAO" refId="saleDAOTarget">
        <ehcache:caching cacheName="saleCache" methodName="findAll"/>
        <ehcache:flushing cacheNames="saleCache" methodName="saveSaleRecord" when="after"/>
    </ehcache:proxy>

    <bean id="saleDAOTarget" class="byteco.de.spring.SaleDAOImpl">
        <property name="namedParameterJdbcTemplate" ref="jdbcTemplate"></property>
    </bean>

    <bean id="datasource" class="org.apache.commons.dbcp.BasicDataSource">
        <property name="driverClassName" value="com.mysql.jdbc.Driver"/>
        <property name="username" value="root"/>
        <property name="password" value="password"/>
        <property name="initialSize" value="5"/>
        <property name="url" value="jdbc:mysql://localhost:3306/demo"/>
    </bean>

    <bean id="jdbcTemplate" class="org.springframework.jdbc.core.namedparam.NamedParameterJdbcTemplate">
        <constructor-arg type="javax.sql.DataSource" ref="datasource"/>
    </bean>
</beans>

<强> ehcache.xml中 

<ehcache>
    <defaultCache
            maxElementsInMemory="500" eternal="true" overflowToDisk="false" memoryStoreEvictionPolicy="LFU"/>
    <cache name="contactCache" maxElementsInMemory="500" eternal="true" overflowToDisk="false"
           memoryStoreEvictionPolicy="LFU"/>
</ehcache>

对于ehcache 3.x，您可以参考以下ehcache.xml模板：

    <config
    xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance'
    xmlns='http://www.ehcache.org/v3'
    xsi:schemaLocation="
        http://www.ehcache.org/v3 http://www.ehcache.org/schema/ehcache-core-3.0.xsd">

  <cache alias="ready-cache">
    <key-type>java.lang.Long</key-type>
    <value-type>com.pany.domain.Product</value-type>
    <loader-writer>
      <class>com.pany.ehcache.integration.ProductCacheLoaderWriter</class>
    </loader-writer>
    <heap unit="entries">100</heap>
  </cache>

</config>

基本上，根据上面的xsd声明更新对ehcache的xsd的引用。 有关如何为ehcache 3.x使用不同的XML选项的更多详细信息，请参阅ehcache documentation for JSR
