mongoose2pojo

Converts MongooseJS schemas to POJO (Plain Old Java Object)

Example usage

my@comp:~$ mkdir schemas && cd schemas
# COPY SCHEMA FILES TO THE ~/schemas DIRECTORY
my@comp:~/schemas$ npm install mongoose
my@comp:~/schemas$ sudo npm install mongoose2pojo -g
my@comp:~/schemas$ mongoose2pojo *.js

mongoose2pojo expects that your schema files are nodejs modules exposing Schema object to module.exports.

Using as command line executable

my@comp:~/code/schemas$ mongoose2pojo image-schema.js
Created POJO file. Size: 1797	 /home/my/schemas/ImagePojo.java

File image-schema.js.

var Schema = require("mongoose").Schema;

module.exports = new Schema({
  ref:  { type: Schema.ObjectId, ref: 'Asset', index: true },
  time: { type: Date, index: true },
  type: String
}, { collection: 'myimage' });

File ImagePojo.java gets created:

import java.util.Date;
import java.util.UUID;
import java.util.Map;

public class Myimage{
	private UUID ref;
	private Date time;
	private String type;
	private UUID id;

	public UUID getRef() {
		return this.ref;
	}
	public void setRef(UUID ref) {
		this.ref = ref;
	}
	public Date getTime() {
		return this.time;
	}
	public void setTime(Date time) {
		this.time = time;
	}
	public String getType() {
		return this.type;
	}
	public void setType(String type) {
		this.type = type;
	}
	public UUID getId() {
		return this.id;
	}
	public void setId(UUID id) {
		this.id = id;
	}
}

Using as library

var Schema = require("mongoose").Schema;
var m2p = require("mongoose2pojo");
var converter = m2p({
  className: "User"
});
var javaCodeString = converter.parse({
  name: String,
  login: { type: String, required: true },
  registeredBy: { type: Schema.ObjectId, ref: 'User', index: true }
});

The resulting javaCodeString is:

import java.util.Date;
import java.util.UUID;
import java.util.Map;

public class User{
	private String name;
	private String login;
	private UUID registeredBy;
	private UUID id;

	public String getName() {
		return this.name;
	}
	public void setName(String name) {
		this.name = name;
	}
	public String getLogin() {
		return this.login;
	}
	public void setLogin(String login) {
		this.login = login;
	}
	public UUID getRegisteredBy() {
		return this.registeredBy;
	}
	public void setRegisteredBy(UUID registeredBy) {
		this.registeredBy = registeredBy;
	}
	public UUID getId() {
		return this.id;
	}
	public void setId(UUID id) {
		this.id = id;
	}
}

Alternatively you can generate POJO text from js schema file. No files will be created.

var contents = m2p().parseFile(fileName);

Or you can generate POJO file from js schema file. A file ImagePojo.java will be created right next to the existing schema file.

m2p.convertFile("image-schema.js");
