JWS Object Relational Mapping

Introduction

When it came to using an ORM Lib in java I used ORMLite before. It worked quite well, but I didn't like the query builder.

Another thing was that I wanted to have control over the JDBC Wrapper to have a simple way of implementing an auto-reconnect function, if it gets disconnected for some reason.

I finally decided to make an own ORM that fits my needs and here it is.

Documentation

You can find the current docs on our website. This is a work-in-progress project though so it's not yet complete.

Example usage

Model

@Dates@SoftDeleteclassUserextendsModel {
@Columnintid;
@ColumnStringname;
@ColumnTimestampcreatedAt;
@ColumnTimestampupdatedAt;
@ColumnTimestampdeletedAt;
}

Usage

//Create connection, initialize reposSQLsql = newMySQL("localhost",3306,"mydb","myuser","changeme1234");
ORMConfigconfig = newORMConfig().setDefaultSize(255); //optionalRepo<User> repo = ORM.register(User.class, sql, config);
//Create the table if it doesn't exist (optional)repo.migrate();
//Print all usernamesfor(Useruser : Repo.get(User.class).all()){
System.out.println(user.name);
}

Maven

Dependency

<dependency>

Driver

You also need to add the driver you want to use. JavaWebStack ORM comes with a wrapper for com.mysql.jdbc.Driver, but you can also create an own wrapper implementing the interface SQL.
