Micronaut Euro Rates Library

September 3, 2020

Tags: #micronaut

I have published a Micronaut Java library to consume the Euro foreign exchange reference rates XML feed published by the European Central bank.

The library has a transitive dependency to Micronaut Jackson XML and because of that it is able to create a Micronaut Declarative HTTP Client to consume an XML payload such as:

<gesmes:Envelope xmlns:gesmes="http://www.gesmes.org/xml/2002-08-01" xmlns="http://www.ecb.int/vocabulary/2002-08-01/eurofxref">
<gesmes:subject>Reference rates</gesmes:subject>
<gesmes:Sender>
<gesmes:name>European Central Bank</gesmes:name>
</gesmes:Sender>
<Cube>

</Cube>
</Cube>
</gesmes:Envelope>

and bind it to a JavaBean:

EuroRatesApi api = ...
GesmesEnvelope envelope = api.currentReferenceRates().blockingGet()
