Load Json content into a POJO class.

This library is meant to be used as a dependency for a project built on a Java EE Application Server.

Getting Started

These instructions will get you a copy of the project up and running on your local machine for development and testing purposes. See package for notes on how to package the project and use it as dependency.

Dev Prerequisites

Maven
Java 9 JDK
Git

Installing

A step by step series of examples that tell you how to get a development env running

git clone https://github.com/pabloame/loadjsonfile.git

Running the tests

You can run unit test with the following command:

mvn test

mvn package

A jar file will be generated in target folder, you can add it as dependency to your project.

In case you want to install it into you local maven repository use:

mvn install

and then add it as:

<dependency>
 <groupId>com.pam.loadjsonfile</groupId>
 <artifactId>loadjsonfile</artifactId>
 <version>1.0-SNAPSHOT</version>

Use cases

Loading a json file

It loads a java class MyDummyClass annotated with @LoadJsonFile with content from a json file with same class name.

Example

@Singleton
@LoadJsonFile
public static class MyDummyClass {
    private String name;
    private int age;
    private boolean active;

    public String getName() {
        return name;
    }

    public int getAge() {
        return age;
    }

    public boolean isActive() {
        return active;
    }
}

it will be created with the information stored in MyDummyClass.json file

{
  "name": "Name",
  "age": "29",
  "active": false
}

Loading a json file with different name

In case your json file is named differently to your java class you can specify the name in the annotation.

Example

@Singleton
@LoadJsonFile(fileName = "config.json")
public static class MyDummyClass {
    private String name;
    private int age;
    private boolean active;

    public String getName() {
        return name;
    }

    public int getAge() {
        return age;
    }

    public boolean isActive() {
        return active;
    }
}

and it will be created with the information stored in config.json

{
  "name": "Name",
  "age": "29",
  "active": false
}
