am i using correct class(ehcache) in application context...?

Answer 1

You used "pwId" as a cache name in your annotation. So you have to define a cache region named "pwId", rather than "editProgram".
Your cache region definition in ehcache.xml should look like this:
<cache name="pwId"
maxElementsInMemory="1000"
eternal="true"
overflowToDisk="false"
memoryStoreEvictionPolicy="LFU" />

Answer 2

try
#Cacheable("pwId")
if your xml config is:
<cache name="pwId"
maxElementsInMemory="1000"
eternal="true"
overflowToDisk="false"
memoryStoreEvictionPolicy="LFU" />

Answer 3

Try
#Cacheable(key = "#a0", value = { "pwId" })
instead
#Cacheable(key = "#pwId", value = { "pwId" })
