GsonUtility is a Java library providing a generic implementation of https://github.com/google/gson to convert Java Objects into JSON or JSON strings to an equivalent Java Object.
This generic implementation already works out-of-the-box. You only need to specify your desired object type. Check example classes in utility to get a quick start.
- Provide a generic abstract class to handle conversion for you
- Provide subclasses for different object types to simplify conversion with a
write()andread()method - Custom subclasses can be extended from the abstract base class to support custom objects
- ArrayList<T>
- HashMap<K,V>
- Object
Read JSON and convert to ArrayList:
ReadWriteArrayList<TestClass> readWriteObject = new ReadWriteArrayList<>();
readWriteObject.setLocation(System.getProperty("user.dir") + "/tests/arraylist.json");
ArrayList<TestClass> testObject = readWriteObject.read();
System.out.println(testObject);
Write ArrayList to JSON:
ReadWriteArrayList<TestClass> readWriteObject = new ReadWriteArrayList<>();
readWriteObject.setLocation(System.getProperty("user.dir") + "/tests/arraylist.json");
ArrayList<TestClass> testObject = new ArrayList<>();
testObject.add(new TestClass(1, "john"));
testObject.add(new TestClass(2, "doe"));
readWriteObject.write(testObject);
Implemented another object type? Feel free to contribute it.
