Sommer
provides a convenient utility for building JSON strings from Java objects. The package ships with Jackson as a transitive dependency, so you don’t need to explicitly include it in your project.
Sommer
package allows you to:
- Convert Java objects into JSON strings.
- Use either compact or pretty-printed JSON formats.
To use Sommer
in your project, add the following dependency to your Maven pom.xml
:
<dependency>
<groupId>com.yourorg.sommer</groupId>
<artifactId>sommer</artifactId>
<version>1.0.0</version>
</dependency>
If you are using Gradle, add this to your build.gradle
:
implementation 'com.yourorg.sommer:sommer:1.0.0'
Note: The Jackson library is included as a transitive dependency, so no additional configuration is needed for JSON processing.
Here is an example demonstrating how to use the Sommer
package:
import com.yourorg.sommer.Sommer;
import java.util.List;
import java.util.Arrays;
public class Main {
public static void main(String[] args) {
try {
// Step 1: Create a list of objects to be converted to JSON
List<Object> sampleData = Arrays.asList(
"John Doe",
42,
true,
new String[]{"Java", "Spring"}
);
// Step 2: Use the Sommer.JSONBuilder to build a Sommer instance
Sommer sommer = new Sommer.JSONBuilder()
.addData(sampleData) // Add data to the builder
.parseToJSON() // Convert data to JSON string
.build(); // Build the Sommer instance
// Step 3: Access the JSON string from the Sommer instance
System.out.println("Pretty-Printed JSON:");
System.out.println(sommer.getData());
} catch (Exception e) {
e.printStackTrace();
}
}
}
Using the sample data from the example:
Pretty-Printed JSON:
[
"John Doe",
42,
true,
[
"Java",
"Spring"
]
]
- If the data cannot be converted to JSON (e.g., invalid input), the method
parseToJSON
will throw aJsonProcessingException
. Ensure you handle this exception.
This package can be extended to:
- Write JSON output directly to files or streams.
- Support additional data formats like XML or YAML.
- Add validation logic for input data.
The Sommer
package simplifies JSON serialization while providing flexibility through the builder pattern. Get started with clean, pretty-printed JSON output in just a few lines of code!
