Manage My Money Server - MyBatis

Manage My Money is a simple application to record and analyze your income and expenses. It demonstrates best practices in developing applications using Java, REST and MyBatis. Its functionality is the same as that of the JavaScript version. There is also an AngularJS based front-end here.

Domain Model

Requirements

• Java SE 8 (JDK)
• Maven version 3.x
• PostgreSQL and postgresql93-devel (development header files and libraries)

Quick Start

• Create a Postgres database called manage-my-money

• Download the following files that will be used to initialize the database

  • create-schema.sql
  • load-data.sql

• Change directory to the location where you downloaded the files and initialize the database:

    $ psql manage-my-money
    manage-my-money=# \i create-schema.sql
    manage-my-money=# \i load-data.sql
  

• Open a terminal (command line) window

• Clone this repo

• Make sure that src/main/resources/mybatis-config.xml has the correct database parameters

Run the application locally:

$ mvn spring-boot:run

To verify that the application is working correctly, point your browser to http://localhost:8080/accounts - you should see a response with a list of accounts in JSON format.

Folder Structure

manage-my-money-mybatis/src/main/java/org/archfirst/mmm
    /adapter
    /application
    /domain
    /persisence

The source folders arrange the application into logical layers as suggested by the Hexagonal Architecture (a.k.a. the Onion Architecture):

• The adapter layer adapts interactions from the external world to the application layer. This layer contains the REST adapter that converts incoming HTTP messages to a format acceptable by the application layer.

• The application layer coordinates high-level activities such as creation of the domain objects and asking them to perform tasks requested by the external world.

• The domain layer encapsulate the state and behavior of the business domain. It consists of entities and value objects. See this article for a detailed description of the domain layer.

• The persistence layer is responsible for storing and retrieving the domain objects using the persistence library called MyBatis.
