Example that shows how to use QueryDSL with Neo4j.

Person.java

package com.github.timmystorms.querydsl.entity;

import com.mysema.query.annotations.QueryEntity;

@QueryEntity
public final class Person {

    private Long id;
    
    private String firstName;
    
    private String lastName;
    
    public Person() {
        
    }
    
    public Person(final String firstName, final String lastName) {
        this.firstName = firstName;
        this.lastName = lastName;
    }

    public Long getId() {
        return id;
    }

    public void setId(Long id) {
        this.id = id;
    }

    public String getFirstName() {
        return firstName;
    }

    public void setFirstName(String firstName) {
        this.firstName = firstName;
    }

    public String getLastName() {
        return lastName;
    }

    public void setLastName(String lastName) {
        this.lastName = lastName;
    }
    
}

PersonTest.java

package com.github.timmystorms.querydsl.entity;

import static org.junit.Assert.assertEquals;
import static org.neo4j.cypherdsl.CypherQuery.node;
import static org.neo4j.cypherdsl.CypherQuery.nodesById;
import static org.neo4j.cypherdsl.CypherQuery.start;
import static org.neo4j.cypherdsl.querydsl.CypherQueryDSL.toBooleanExpression;

import org.junit.Test;

public class PersonTest {

    @Test
    public void queryFirstName() {
        final QPerson person = QPerson.person;
        final String query = "CYPHER 1.8 START person=node(1) WHERE person.firstName=\"P\" RETURN (person)";
        assertEquals(
                query,
                start(nodesById("person", 1)).where(toBooleanExpression(person.firstName.eq("P"))).returns(
                        node("person")).toString());
    }

}

If you want to make Querydsl and Neo4j also work from Eclipse builds you need to follow the tutorial at http://blog.mysema.com/2010/10/using-querydsl-in-eclipse.html but include the querydsl-apt-X.X.X-general-one-jar.jar instead of or together with the JPA one.
