java-json-toolkit
The json-toolkit repository contains the code to the following libraries:
json-toolkit-text: basic library for conversion between textual representations and special Java classesjson-toolkit-java(available soon)
json-toolkit-text
The json-toolkit-text library can be used to convert textual representations of JSON values into Java objects and to convert those Java objects into textual representations. The conversion into the textual version can use a configurable formatter to create texts that are more easy to read by humans.
Installation
To use the library in your projects, you have to create the dependency to the library.
Gradle:
dependencies {
implementation 'de.d-coding:json-toolkit-text:1.0.2'
}
Maven:
<dependency>
<groupId>de.d-coding</groupId>
<artifactId>json-toolkit-text</artifactId>
<version>1.0.2</version>
</dependency>
Usage
Sample usage code snippets.
Parsing JSON texts:
String jsonText = "{\"foo\":{}}";
JSONLLParser parser = new JSONLLParser();
JSONValue jsonValue = parser.parse(stringValue);
or
JSONObject object = JSON.decode("{\"foo\":{}}");
or
JSONArray array = JSON.decode("[1, 2, null, 3]");
Manipulating JSON values:
JSONValue jsonValue = new JSONObject();
jsonValue.put("foo", "bar");
or
JSONValue jsonValue = JSON.decode("{\"foo\":{}}");
JSONObject object = (JSONObject)jsonValue.get("foo");
object.put("bar", 42);
or
JSONValue jsonValue = JSON.decode("{\"foo\":{}}");
jsonValue.<JSONObject>getAs("foo").put("bar", 42);
Convert to unformatted text:
JSONValue jsonValue = new JSONObject();
jsonValue.put("foo", "bar");
String text = jsonValue.toString();
Convert to formatted text:
JSONValue jsonValue = new JSONObject();
jsonValue.put("foo", "bar");
JSONFormatter formatter = new JSONFormatter();
String text = formatter.toString(jsonValue);
or
JSONValue jsonValue = new JSONObject();
jsonValue.put("foo", "bar");
JSON.encode(jsonValue);
Convert to formatted text with indention of 3 spaces:
JSONValue jsonValue = new JSONObject();
jsonValue.put("foo", "bar");
JSONFormatter formatter = new JSONFormatter();
JSONFormatterSettings settings = formatter.getSettings();
settings.setIndentionString(" ");
String text = formatter.toString(jsonValue);
