Maven

Tod Commons Jackson is available on Maven Central. To use it, put this in the dependencies section of your pom.xml:

    <dependency>
        <groupId>eu.trentorise.opendata</groupId>
        <artifactId>tod-commons-jackson</artifactId>
        <version>1.1.0</version>
    </dependency>

In case updates are available, version numbers follows semantic versioning rules.

Using Jackson Module

Tod Commons Jackson allows serializing and deserializing Dict and LocalizedString in Jackson 2.x by installing the TodCommonsModule in a Jackson ObjectMapper. Also, some basic utility to work with Jackson is provided in the Jacksonizer class.

You can register TodCommonsModule in your own Jackson ObjectMapper:

    ObjectMapper om = new ObjectMapper();
    om.registerModule(new GuavaModule());
    om.registerModule(new TodCommonsModule());

    String json = om.writeValueAsString(LocalizedString.of(Locale.ITALIAN, "ciao"));
    LocalizedString reconstructedLocalizedString = om.readValue(json, LocalizedString.class);

Notice we have also registered the necessary Guava (for immutable collections) and Tod Commons modules (for Dict and LocalizedString).

To register everything in one command just write:

    ObjectMapper om = new ObjectMapper();
    TodCommonsModule.registerModulesInto(om);

Simple usage example

    ObjectMapper om = new ObjectMapper();
    TodCommonsModule.registerModulesInto(om);

    String json = om.writeValueAsString(LocalizedString.of(Locale.ITALIAN, "ciao"));
    LocalizedString reconstructedLocalizedString = om.readValue(json, LocalizedString.class);

Logging

Tod Commons Jackson uses native Java logging system (JUL). If you also use JUL in your application and want to see Tod commons jackson logs, you can take inspiration from tod-commons test logging properties. If you have an application which uses SLF4J logging system, you can route logging with JUL to SLF4J bridge, just remember to programmatically install it first.
