Jackson: Get TOML from Java object

Step 1: Get an instance of TomlMapper.

TomlMapper mapper = new TomlMapper();

 

Step 2: Serialize java object to string using writeValueAsString method.

String toml = mapper.writeValueAsString(emp);

 

Find the below working application.

 

Employee.java

 

package com.sample.app.dto;

public class Employee {
	private int id;

	private String firstName;

	private String lastName;

	public int getId() {
		return id;
	}

	public void setId(int id) {
		this.id = id;
	}

	public String getFirstName() {
		return firstName;
	}

	public void setFirstName(String firstName) {
		this.firstName = firstName;
	}

	public String getLastName() {
		return lastName;
	}

	public void setLastName(String lastName) {
		this.lastName = lastName;
	}

}

ObjectToToml.java

package com.sample.app;

import java.io.IOException;

import com.fasterxml.jackson.dataformat.toml.TomlMapper;
import com.sample.app.dto.Employee;

public class ObjectToToml {

	public static void main(String[] args) throws IOException {
		TomlMapper mapper = new TomlMapper();
		
		Employee emp = new Employee();
		emp.setId(1);
		emp.setFirstName("Rama Devi");
		emp.setLastName("G");
		
		String toml = mapper.writeValueAsString(emp);
		System.out.println(toml);
		
	}

}

Output

id = 1
firstName = 'Rama Devi'
lastName = 'G'
