Can load config form other place?

How to use a existed ehcacheManager?

    <bean id="ehcacheManager"
        class="org.springframework.cache.ehcache.EhCacheManagerFactoryBean">
        <property name="configLocation" value="classpath:my-ehcache.xml" />
    </bean>

new ehcache version :
// https://mvnrepository.com/artifact/net.sf.ehcache/ehcache-core
compile group: 'net.sf.ehcache', name: 'ehcache-core', version: '2.6.11'

在ehcache.xml配置了默认的缓存信息，时间300s

在mapper.xml配置过期时间3s，测试结果，还是300s有效果

使用springboot 框架

No need to lock accesses to cache. EhCache provides locking by default.

Hello,
Is this library is supported with ehcache v3.x, don't found the information on web page : http://www.mybatis.org/ehcache-cache/

Best regards

MyBatis version 3.2.0
in putObject param value is ArrayList and you don't check if is it empty and write to cache, when next time call getObject it returns empty list but in database row has already
and another forks with cache the same situation
example:
SqlSession sqlSession = sqlSessionFactory.openSession();
....
try{
Types t=typesMapper.getTypeByName("cool");
if(t==null){
typesMapper.create('cool');
}
}
finally{
sqlSession .close();
}
//put to cache empty list
......
openSession();
Types t=typesMapper.getTypeByName("cool");//get from cache empty list but object was created

Hi anybody,

I want to integrate ehcache into spring, mybatis, but I did't find any useful materials on mybatis site. Does anyone have experience on this?

Best Regard!

@emacarron Lack of a better way to contact you! I've had an open pull request which has evolved over the last few months and follows all the others I've been doing. hazelcast-cache. Can you take a look at it?

I am disheartened to see that downloading the jar is too slow in China!I can't wait for it,and I am going to mad!!! It remains the status :

First I want to thank you for that library, seamless integration to ehcache.

As the documentation suggest we can use EhBlockingCache, I tried to use since I have use case where I have concurrent write to same entry.
Except it fails for every request with NPE.

Looking a the code, it seems that

this.cache

is never initialized in EhBlockingCache

I'm revisiting the use of mybatis/ehcache-cache in a web application. I have setup a few MyBatis mappers to use org.mybatis.caches.ehcache.EhcacheCache and I have them configured via a central ehcache.xml file with individual cache managers () configured for each mapper.

Using a profiler and viewing MBeans for net.sf.ehcache, I can see the mappers being setup according to my configuration, what I don't see is a respect for the maxBytesLocalDisk setting I provide. In other words, as I query my website, and run the disk usage command on my file system, looking at the mybatis cache path, the disk usage seems to grow without limit.

I've tried both setting a global maxBytesLocal disk as well as a maxBytesLocalDisk at an individual cache manager level. Below is my latest setup.

Snippet from mapper.xml file:

<mapper namespace="org.cbioportal.persistence.mybatis.SampleMapper"> <cache readOnly="true" type="org.mybatis.caches.ehcache.EhcacheCache"/>
...
</mapper>

Snippet from ehcache.xml:

<ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="ehcache.xsd" updateCheck="false" monitoring="autodetect" maxBytesLocalDisk="${mybatis.cache.maxBytesLocalDisk}" dynamicConfig="true" name="myapp-ehcache">

<cache name="org.cbioportal.persistence.mybatis.SampleMapper" statistics="${mybatis.cache.statistics}" maxEntriesLocalHeap="${mybatis.cache.SampleMapper.entrysize}">
<persistence strategy="localTempSwap"/>
</cache>
</ehcache>

For testing I currently have mybatis.cache.maxBytesLocalDisk set to 10M, but I'm already at 145M after a few queries:
du -sh ~/local/apache-tomcat/ehcache/org%002ecbioportal%002epersistence%002emybatis%002e%0053ample%004dapper.data
145M /Users/grossb1/local/apache-tomcat/ehcache/org%002ecbioportal%002epersistence%002emybatis%002e%0053ample%004dapper.data

This latest configuration sets a global maxBytesLocalDisk (within ehcache element), but I've tried to set them at the mapper/cache manager level (within cache element) with the same result.

Any ideas what I'm doing wrong?

Thanks for your time and attention to this matter - and thanks for the library, very useful in my application!

Is there anyway to integrate the Ehcache monitor within the mapper XML file? The only documentation I find on setting up the monitor is through a separate ehcache.xml. If thats the case, can you have an ehcache.xml file to specify the monitor settings and have cache elements defined in the mapper xml files simultaneously?

Thanks!
