ArangoDB - BigDecimal

Simple example

@Data
@Document("product")
@Accessors(chain = true)
public class Product {
    @Id
    private String id;
    private BigDecimal cost;
}

ArangoDB configuration:

@Override
public Builder arango() {
    final Builder builder = new Builder();
    arangoDbConfig.getHosts().forEach(host -> builder.host(host.getHost(), host.getPort()));
    return builder
            .user(arangoDbConfig.getUser())
            .password(arangoDbConfig.getPassword())
            .registerModule(new VPackJdk8Module());
}

Reading document generate exception:

Invocation of init method failed; nested exception is org.springframework.data.mapping.model.MappingInstantiationException: Failed to instantiate java.math.BigDecimal using constructor NO_CONSTRUCTOR with arguments

Dependency:

  1. SpingBoot 1.5.9
  2. Arangodb-spring-data 1.0.1
  3. Velocypack-module-jdk8 1.0.2

Ok, just forget BigDecimal is mapped to HashMap. Creating queries (biggerThan/lessThan) will be bizarre. I change the data type to Double.

You need to define JsonSerializer and JsonDeserializer for class which contains BigDecimal, because ArangoDB do not have support for that type of data. Check this arango serializer documentation: link
