Rest-API support for Java 8 Time module (java.time)

Support
#1

Hi!

We have created services to be open for the rest API. Many of these services have methods that take in java.time objects, primarly LocalDate, I have tried to implement this in the following way:

Interface

public interface MyService {
    String NAME = "app_MyService";
    void method(LocalDate date);
}

Implementation

@Service(MyService.NAME)
public class MyServiceBean implements MyService {

    public void method(LocalDate date) {
    ...
    }
}

rest-services.xml

<service name="app_MyService">
    <method name="method">
        <param name="date" />
    </method>
</service>

When I try to call this service with payload:

{
     "date": "2020-10-01"
}

It doesn’t work. I get a 400 back with message Invalid parameter value for date.

The logs show a com.google.gson.JsonSyntaxException: java.lang.IllegalStateException: Expected BEGIN_OBJECT but was STRING at line 1 column 1 path $

I have also tried to specify the param name in rest-services.xml with:

<param name="date"  type="java.time.LocalDate" />

But still no success.

If I simply change java.time.LocalDate to java.util.Date everything works as expected. Is Java 8 Time Module supported in the rest-api addon?

Hello @bartekspitza!

Java 8 Date/Time API isn’t currently supported in the rest-api addon requests.
I’ve created an issue for this improvement.
