Optional and continuing

 So, some thing I've bothered myself with.

We have a common idiom where we do something like:

var result = doSometThing();

if(result == null) {

  return handleEmptyCase();

}

// continue logic with result

 

 

With Optional, that has changed, somewhat...

var result = doSometThing();

if(result.isEmpty()) {

  return handleEmptyCase();

}

var actualResult = result.get();

// continue logic with actualResult

 

But this is... messy.

 

We could go functional on it:

 

return doSomeThing()

  .map(result -> doWithActualResult(result))

  .orElse( () -> return handleEmptyCase();)
 

But this isn't it either.
We now have the else clause handling our special exit, which is not what we prefer, we prefer to exit early. 

So, sometimes an optional is... not as nice... 

 

Something interesting is:

Spring's conditional annotation with properties

Spring has a nice @Conditional annotation, to have the option to have beans be available in the context depending a specific condition (Of course, this can also be realized by using @Configuration objects, but that's a different post). Ideally, we'd have the option to have a condition evaluate to true or false depending on a property. Sadly, Spring does not support that out of the box. Googling and looking around gives a partial solution, but the complete one here, so we won't forget: /** * Components annotated with ConditionalOnProperty will be registered in the spring context depending on the value of a * property defined in the propertiesBeanName properties Bean. */ @Target({ ElementType.TYPE, ElementType.METHOD }) @Retention(RetentionPolicy.RUNTIME) @Conditional(OnPropertyCondition.class) public @interface ConditionalOnProperty { /** * The name of the property. If not found, it will evaluate to false. */ String value(); /** * if the p...

Using spring's @transactional to only roll back when you really want to

In spring you can use the @Transactional annotation to marcate public methods as transactions. Any exception thrown in such an exception causes a rollback... Any exception? No, spring only does so on runtime exceptions. Checked exceptions are allowed and do not result in a rollback. And even then, you can allow some transactions to rollback, or not, with the proper properties for the transactions. For examle, @Transactional(rollbackFor="MyCheckedException.class") will rollback for a specific checked exception, and similarly, you can use @Transactional(noRollbackFor="MyUncheckedException.class") for unchecked exceptions. Of course, you might want to make it a little simpler on yourself. This article on stackoverflow shows us a different way: we can use our own transaction handler by overriding spring's. Let's have a sample interface which defines whether an exception should perform a rollback: interface ConfigurableRollback shouldRollbackOnE...

On SSL certificate generation

 So, more stuff I always forget... how to properly generate SSL certs. Well, easiest is with openssl (of course) Something like: openssl req -new -newkey rsa:2048 -nodes  -sha256 -subj "/C=NL/ST=Utrecht/L=Utrecht/O=Cooperatieve Rabobank U.A./OU=RASS Groep ICT/CN=my-common-name.host.nl" -keyout somename-prod.key -out somename-prod.csr   That can get you a certificate sign request (csr) and the appropriate key.   Of course, you want to then import those keys into a keystore. The trick to doing that is to convert it to a pkcs12 format where it can have the certificate and the key combined.   openssl pkcs12 -export -inkey somename-prod.key -in somename-prod.rabobank.nl.crt -out somename-prod.p12  Note that the crt is the signed certificate, acquired through getting the csr generated above approved..   This p12 file you can import using something like KeyStore Explorer.   After that, you can also append the root certificates of the original cert, to en...
