parsing ehcache.xml not working in grails

[he...@raumo.de]

1. What version of Ehcache you are currently using;
2. Paste the configuration for the Cache/CacheManager you have an issue with;
3. Add any name and version of other library or framework you use Ehcache with (e.g. Hibernate);
4. Providing JDK and OS versions maybe useful as well.

1: cache-ehcache:3.0.0.M1

2: application.yml: 

grails:

    cache:

        ehcache:

            ehcacheXmlLocation: 'ehcacheCustom.xml'

            lockTimeout: 200

ehcacheCustom.xml:

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

<ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="ehcache.xsd" updateCheck="false">

     Default Cache Configuration, with name 'default'

    <defaultCache maxElementsInMemory="50" eternal="false"

                  overflowToDisk="false" memoryStoreEvictionPolicy="LFU" />

    <cache name="employeeCache" maxElementsInMemory="50" eternal="false"

           overflowToDisk="false" memoryStoreEvictionPolicy="LFU" />

</ehcache>

thanks for any suggestions

[Alex Snaps]

Hey Heiko,

To your question, it looks like you're trying to use an ehcache 2.x XML file there... but you're using 3.0.0.m1. This won't work. 

Hence the `Cannot find the declaration of element 'ehcache'.`

See http://www.ehcache.org/documentation/3.5/xml.html

Also, I'd use a newer version, or at least a stable one...

Hey Alex,

thanks for the fast reply. Well i guess there is no newer version of eh-cache for grails 3 out there (as u can see here: https://repo.grails.org/grails/core/org/grails/plugins/cache-ehcache/). Is an example ehcache.xml for version 3.0.0.M1 out there? these xml documentations are confusing me :/

[Henri Tremblay]

Have a look here: http://www.ehcache.org/documentation/3.5/xml.html

However, note that 3.0.0.m1 is pretty old. And beta.

Try 3.5. Hopefully it will work with grails. And we would like to know if it doesn't.

Henri

Hello,

There is a confusion around versions here. 3.0.0.M1 is the version of the Grails plugin.

It internally uses Ehcache 3.3.1.

And so while you should be able to upgrade to Ehcache 3.5, the most important thing is what Alex said first: have a look at the 3.x documentation as XML format is totally different.

Regards,

Louis

I tried 3.5.0. after dependency updates there was en error on start up:

2018-07-04 17:45:37.743  WARN --- [           main] ationConfigEmbeddedWebApplicationContext : Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'grailsApplicationPostProcessor' defined in api2.Application: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [grails.boot.config.GrailsApplicationPostProcessor]: Factory method 'grailsApplicationPostProcessor' threw exception; nested exception is java.lang.NoClassDefFoundError: grails/plugin/cache/ehcache/EhcacheConfiguration

so i guess there is a reason why the 3 year old 3.0.0.M1 is the "newest" ehcache version for grails. i don't know how other grails developers handle this

to the xml-file: i will create one these days and let u know if it worked with 3.0.0M1

Heiko

[he...@raumo.de]

thx, i will look at it these days

grails/plugin/cache/ehcache/EhcacheConfiguration is not Ehcache code. It is the grails plugin code. So it means the cache-ehcache is not in your classpath.

sooo, base on http://www.ehcache.org/documentation/3.5/xml.html i got somethin like this:

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

<config

xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance'

xmlns='http://www.ehcache.org/v3'

xsi:schemaLocation="ehcache-core.xsd">

    <cache alias="test">    

    </cache>

</config>

of course it wont work because its a pretty slim xml with no configuration (how for example do i configure TimeToLive?) This documentation says nothing about it and other important configurations. Is there a documentation in more detail out there? I couldn't find all the stuff i need in this documentation. Also an example xml with example cache nodes for different scenarios would be very helpful

Greetings

Heiko

It’s all in the doc and for a complete description, see the XSD itself:

http://www.ehcache.org/documentation/3.5/xsds.html

 Plus the doc links to an example here:

http://www.ehcache.org/documentation/3.5/examples.html#xml-with-107-extension

`expiry` controls that.

Thx Alex & Henri,

my bad. u just read the link "XML Configuration" but obviously all other links belong to xml configuration aswell. no my caches work fine with primitive datatypes. I guess thats because of the default serialziers. For a custom pojo i need to write my own serialzier? 
. 

[Louis Jacomet]

That's correct - have a look at http://www.ehcache.org/documentation/3.5/serializers-copiers.html for the concepts and what's needed depending on your cache topology.

Louis
