Guava not returning cached object - memcached

Question

I am using Guava cache but for some reason my CacheBuilder is not returning already cached object, it always goes for expensive call. I am using this as follows;
EDIT
LoadingCache<ProfileDetails, OutAuthProfile> profileCache;
private void init(int maxCacheSize) {
// Check if we have it in our cache
profileCache = CacheBuilder.newBuilder().maximumSize(maxCacheSize) // maximum
// 100
// records
// can
// be
// cached
.build(new CacheLoader<ProfileDetails, OutAuthProfile>() { // build
// the
// cacheloader
#Override
public OutAuthProfile load(ProfileDetails profileDetails) throws Exception {
// make the expensive call
return getFilterAndSelectFromT24(profileDetails);
}
});
}
/**
* Get the AuthProfile for a provided InAuthProfile. This method will use cache, if not found in cache
* it will call T24 to retrieve the information and store for the next run
* #param profileDetails
* #return
*/
public OutAuthProfile getAuthProfileForSearchDb(ProfileDetails profileDetails) {
try {
return profileCache.get(profileDetails);
} catch (ExecutionException ee) {
ResponseDetails responseDetails = new ResponseDetails();
responseDetails.addError(new Response("EB.SMS-SERVICE-ERROR", CFConstants.RESPONSE_TYPE_FATAL_ERROR, ee
.getMessage(), null));
return new OutAuthProfile(null, null, responseDetails);
}
}
I am calling this as follows;
ProfileDetails profileDetails = T24AuthHelper.getProfile(userName, companyName, t24EntityName);
OutAuthProfile outProfile = authHelper.getAuthProfileForSearchDb(profileDetails);
Following is a basic implementation I am using for equals() and hasCode() in my ProfileDetails object;
public static ProfileDetails getProfile(String userName, String companyName, String t24EntityName) {
return new ProfileDetails(userName, companyName, t24EntityName) {
/**
*
*/
private static final long serialVersionUID = 1L;
#Override
public boolean equals(Object obj) {
if (obj == null || !(obj instanceof ProfileDetails)) {
return false;
}
ProfileDetails other = (ProfileDetails) obj;
return this.getProfileName() == other.getProfileName() &&
this.getCompany() == other.getCompany() &&
this.getResourceName() == other.getResourceName();
}
#Override
public int hashCode() {
int hashCode = 0;
if (getProfileName()!= null)
hashCode += getProfileName().hashCode();
if (getCompany() != null)
hashCode += getCompany().hashCode();
if (getResourceName() != null)
hashCode += getResourceName().hashCode();
return hashCode;
}
};
}
Tests from guava-testlib;
#Test
public void testProfileEqualsImpl() {
ProfileDetails profile11 = T24AuthHelper.getProfile("Name1", "Company1", "Entity1");
ProfileDetails profile12 = T24AuthHelper.getProfile("Name1", "Company1", "Entity1");
ProfileDetails profile21 = T24AuthHelper.getProfile("Name2", "Company2", "Entity2");
ProfileDetails profile22 = T24AuthHelper.getProfile("Name2", "Company2", "Entity2");
EqualsTester eqTester = new EqualsTester()
.addEqualityGroup(profile11, profile12)
.addEqualityGroup(profile21, profile22);
eqTester.testEquals();
}
