A Java ORM based on jLoquent, inspired by Laravel Eloquent.

bjLoquent is actually not so different of jLoquent. You should check the JUnit test file to see how it works. But here is a quick example.
Firstly, in order to use it you have to create a Configuration class, just like this.
Configuration.java
package com.yourpackage;
import org.bjloquent.DBConfig;
import org.bjloquent.DatabaseType;
public class Configuration implements DBConfig {
@Override
public DatabaseType getDatabaseType() {
return DatabaseType.MYSQL;
}
@Override
public String getHostName() {
return "databaseHostname";
}
@Override
public String getPortNumber() {
return "databasePort";
}
@Override
public String getDatabaseName() {
return "databaseName";
}
@Override
public String getUsername() {
return "databaseUsername";
}
@Override
public String getPassword() {
return "yourPassword";
}
}Next to that, you should have created some models. I actually don't know how works migrations on jLoquent, and if they works (that is planned for later). Every model has to be named in cingular, bjLoquent will name it in plurial in the database.
To make a model, you have to define a primary key. But if the primary key is an integer called id, you don't have to specify it name. Here is an example:
User.java
package com.yourpackage;
import org.bjloquent.Model;
import java.sql.Timestamp;
public class User extends Model {
private int id;
private String name;
private String email;
private String password;
private Timestamp joinedDate;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public Timestamp getJoinedDate() {
return joinedDate;
}
public void setJoinedDate(Timestamp joinedDate) {
this.joinedDate = joinedDate;
}
}Conversely, if your primary key is not called id, you will need to specify it just like in the model below.
Player.java (with string UUID)
package com.yourpackage;
import org.bjloquent.Model;
import java.sql.Timestamp;
public class Player extends Model {
private String uuid;
private String name;
private Timestamp joinedDate;
private int score;
public Player() {
// We specify
super.primaryKey = "uuid";
}
public String getUuid() {
return uuid;
}
public void setUuid(String uuid) {
this.uuid = uuid;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public Timestamp getJoinedDate() {
return joinedDate;
}
public void setJoinedDate(Timestamp joinedDate) {
this.joinedDate = joinedDate;
}
public int getScore() {
return score;
}
public void setScore(int score) {
this.score = score;
}
}And here is an example of Main:
Main.java
package com.yourpackage;
import org.bjloquent.Connector;
import org.bjloquent.DBConfig;
import java.util.Random;
public class Main {
public static void main(String[] args) {
Connector connector = Connector.getInstance();
DBConfig config = new Configuration();
connector.setDBConfig(config);
connector.open();
User user = new User();
user.setName("John Doe");
user.setEmail("[email protected]");
user.setPassword("123456");
user.setJoinedDate(new java.sql.Timestamp(System.currentTimeMillis()));
user.create();
System.out.println("ID: " + user.getId());
user.setName("Modified John Doe");
user.save();
Player player = new Player();
String uuid = "";
for (int i = 0; i < 4; i++) {
uuid += String.valueOf((new Random().nextInt(10)));
}
player.setUuid(uuid);
player.setName("John Doe");
player.setJoinedDate(new java.sql.Timestamp(System.currentTimeMillis()));
player.setScore(100);
System.out.println("UUID: " + player.getUuid());
player.create();
player.setScore(200);
player.setName("Modified John Doe");
player.save();
connector.close();
}
}
