spring boot - get java.lang.ArrayStoreException on Springboot and ehcache -

i have method calls webservice , same input arguments, want result cached. so, here did far: main class:

import org.springframework.boot.autoconfigure.springbootapplication; import org.springframework.boot.context.web.springbootservletinitializer; import org.springframework.cache.cachemanager; import org.springframework.cache.annotation.enablecaching; import org.springframework.cache.ehcache.ehcachecachemanager; import org.springframework.cache.ehcache.ehcachemanagerfactorybean; import org.springframework.context.annotation.bean; import org.springframework.context.annotation.componentscan; import org.springframework.core.io.classpathresource;  @enablecaching @componentscan @springbootapplication public class accserver extends springbootservletinitializer {     @bean    public cachemanager cachemanager() {       return new ehcachecachemanager(ehcachecachemanager().getobject());    }     @bean    public ehcachemanagerfactorybean ehcachecachemanager() {       ehcachemanagerfactorybean cmfb = new ehcachemanagerfactorybean();       cmfb.setconfiglocation(new classpathresource("ehcache.xml"));       cmfb.setshared(true);       return cmfb;    }  } 

method cache:

import java.util.list;  import org.springframework.cache.annotation.cacheable; import org.springframework.stereotype.service;  @service public class someclass implements isomeclass {     @override    @cacheable("acc")    public list<integer> trs() {       return websrv.trs();    }  } 

ehcache.xml

<?xml version="1.0" encoding="utf-8"?> <ehcache xmlns:xsi="http://www.w3.org/2001/xmlschema-instance" xsi:nonamespaceschemalocation="http://ehcache.org/ehcache.xsd" updatecheck="false">     <diskstore path="java.io.tmpdir" />     <cache name="acc" maxelementsinmemory="100" eternal="false" timetoidleseconds="120" timetoliveseconds="120" overflowtodisk="true" maxelementsondisk="10000000" diskpersistent="false" diskexpirythreadintervalseconds="120" memorystoreevictionpolicy="lru" /> </ehcache> 

and get:

i use @cacheable("acc") annotation method should cached result. answers appreciated.

the issue @cacheable trs() method (of @service someclass class) not returning list<integer> object because of getting sun.reflect.annotation.typenotpresentexceptionproxy exception.

you need ensure trs() returning list<integer> object.
