additionalProperties java.util.Map is not generated by default when embedding this library and extending DefaultGenerationConfig

[shivamsharma]

Json file is :

 {
        "type" : "object",
        "additionalProperties" : {
            "type" : "number"
        }
}

the code generated is :

package com.cognitree;

import javax.annotation.Generated;
import com.fasterxml.jackson.annotation.JsonInclude;
import org.apache.commons.lang.builder.ToStringBuilder;

@JsonInclude(JsonInclude.Include.NON_NULL)
@Generated("org.jsonschema2pojo")
public class Device {


    @Override
    public String toString() {
        return ToStringBuilder.reflectionToString(this);
    }

}

But expected is :

 public class MyObject {

        private java.util.Map<String, Double> additionalProperties = new java.util.HashMap<String, Double>();

        @org.codehaus.jackson.annotate.JsonAnyGetter
        public java.util.Map<String, Double> getAdditionalProperties() {
            return this.additionalProperties;
        }

        @org.codehaus.jackson.annotate.JsonAnySetter
        public void setAdditionalProperties(String name, Double value) {
            this.additionalProperties.put(name, value);
        }

    }

as per documentation https://github.com/joelittlejohn/jsonschema2pojo/wiki/Reference#additionalproperties

you need to explicitly enable this feature:

RuleFactory ruleFactory = new RuleFactory();
ruleFactory.setGenerationConfig(new DefaultGenerationConfig(){
    @Override
    public boolean isIncludeAdditionalProperties(){
        return true;
    }
});
SchemaMapper schemaMapper = new SchemaMapper(ruleFactory, new SchemaGenerator());

by default this is disabled

You need to remove additionalproperties from your json schema and by default it will include this in your generated class.

@brentryan I have tried removing "additionalProperties" from json but it was not working....

does your plugin configuration look like this? What version are you using?

<plugin>
                <groupId>org.jsonschema2pojo</groupId>
                <artifactId>jsonschema2pojo-maven-plugin</artifactId>

@shivamsharma You don't mention how you're using jsonschema2pojo, either via Maven, Ant, Gradle or embedded in your project. I'm going to assume though that you're using this embedded in your project (using the API directly) because I've just noticed the following bug:

jsonschema2pojo/jsonschema2pojo-core/src/main/java/org/jsonschema2pojo/DefaultGenerationConfig.java

Line 230 in 9202d97

return false;

This should be returning true by default but it is returning false in the v0.4.14. You can work around this using the method that @santhosh-tekuri mentions above, but I'll fix this now.

[shivamsharma]

I tried using both by maven & embedding code. Yeah I am using the code suggested by @santhosh-tekuri. Hope you will fix the bug as soon as possible.
