CacheManager convert error
I use shiro in my web site. My web is SpringMVC+SPring+mybaits.
shiro works well. I don't use cache and there are lots of connection between
web and db. In server console windwo, I find lots of information such as
"2013-10-15 13:43:14,585 INFO [org.apache.shiro.realm.AuthorizingRealm] -
<No cache or cacheManager properties have been
set. Authorization cache cannot be obtained.>".
Then I decide to use cache now. In ApplicationContext.xml, I add followed
sentence:
<bean id="cacheManager"
class="org.apache.shiro.cache.ehcache.EhCacheManager" scope="singleton" /
Then the web counldn't be deployed well. It shows error:
BeanPostProcessor before instantiat
ion of bean failed; nested exception is
org.springframework.beans.factory.BeanCreationException: Error creating bean
wit
h name

lang.IllegalStateException: Cannot convert value of type
[org.apache.shiro.cache.ehcache.EhCacheManager] to required typ
e [net.sf.ehcache.CacheManager] for property 'cacheManager': no matching
editors or conversion strategy found.
What is wrong ? I use shiro-all-1.2.2.jar and ehcache-core-2.6.6.jar.

I am having the exact same problem. It's been a real mystery to me for an embarrassingly long time.
Like you, I can get Shiro to work flawlessly during the normal course of development, but the cache management warnings in the logs compel me to do what you've done here, and I get the exact same error.
I have had no luck figuring out what I'm doing wrong here.

I change the bean id , then It is ok now.
but after I config the followed information, the new error appear.
<bean id="securityManager"
class="org.apache.shiro.web.mgt.DefaultWebSecurityManager">
<property name="realm" ref="myRealm" />
<property name="cacheManager" ref="shirocacheManager" />
</bean>
the error is :
Property 'cacheManager' threw exception; nested exception is org.apache.shiro.cache.CacheException:
net.sf.ehcache.CacheException: Another CacheManager with sam e name 'shiroehcache1' already exists in the same VM.
in ehcache-shiro.xml ,I set the information:
<ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="http://ehcache.org/ehcache.xsd"
name="shiroehcache1">
I only set "shiroehcache1" indeed. what is wrong?

Can you elaborate on what you changed? What did you change in the web.xml that made this work for you?

Finally I find the reason which cause the issue "nested exception is
org.apache.shiro.cache.CacheException: net.sf.ehcache.CacheException:
Another CacheManager with sam e name 'shiroehcache1' already exists in the same VM".
In the web.xml, the xml is invoked twice in either web Context and sping dispatch servlet context.
I changed the web.xml. And cache works well now.
