XJC (JAX-B Compiler) Plugin for generating Guava like toString,equals and hashCode-methods from xml schema

xjc-guava-plugin

Fell in love with Guavas Objects.toStringHelper(), .hashCode() and .equals()? Tired of writing StringBuilders for JAX-WS wsgen generated Beans? This XJC Compiler plugin comes to the rescue and creates yummie standards methods for your JAX-B/WS Beans - with a taste of Guava.

Profit!

Example

This plugin generates guava standard methods for toString, hashCode and equals:

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "thunderbolt", propOrder = {
    "intensity"
})
public class Thunderbolt {

    protected Double intensity;

    public Double getIntensity() {
        return intensity;
    }

    public void setIntensity(Double value) {
        this.intensity = value;
    }

    @Override
    public String toString() {
        return Objects.toStringHelper(this).add("intensity", intensity).toString();
    }

    @Override
    public int hashCode() {
        return Objects.hashCode(intensity);
    }

    @Override
    public boolean equals(Object other) {
        if (this == other) {
            return true;
        }
        if (other == null) {
            return false;
        }
        final Thunderbolt o = ((Thunderbolt) other);
        if (o == null) {
            return false;
        }
        return Objects.equal(intensity, o.intensity);
    }
}

Usage

In contract first scenarios webservice clients models are often generated with jaxws.wsgen or cxf-codegen-plugin
