Dozer: String to date mapping

By specifying the date-format at the field level, we can convert string to date and vice versa.

 

Example

<field>
	<a>manufacturingDate</a>
	<b date-format="MM/dd/yyyy HH:mm:ss:SS">dateString</b>
</field>

 

Find the below working application.

 

Product1.java

package com.sample.app.model;

import java.util.Date;

public class Product1 {

	private Date manufacturingDate;

	public Date getManufacturingDate() {
		return manufacturingDate;
	}

	public void setManufacturingDate(Date manufacturingDate) {
		this.manufacturingDate = manufacturingDate;
	}

	@Override
	public String toString() {
		return "Product1 [manufacturingDate=" + manufacturingDate + "]";
	}

}

 

Product2.java

package com.sample.app.model;

public class Product2 {
	private String dateString;

	public String getDateString() {
		return dateString;
	}

	public void setDateString(String dateString) {
		this.dateString = dateString;
	}

	@Override
	public String toString() {
		return "Product2 [dateString=" + dateString + "]";
	}

}

 

date_to_string.xml

<?xml version="1.0" encoding="UTF-8"?>
<mappings xmlns="http://dozer.sourceforge.net"

	<mapping>
		<class-a>com.sample.app.model.Product1</class-a>
		<class-b>com.sample.app.model.Product2</class-b>

		<field>
			<a>manufacturingDate</a>
			<b date-format="MM/dd/yyyy HH:mm:ss:SS">dateString</b>
		</field>

	</mapping>

</mappings>

 

DateToString.java

package com.sample.app;

import java.io.IOException;
import java.util.Arrays;
import java.util.Date;

import org.dozer.DozerBeanMapper;

import com.sample.app.model.Product1;
import com.sample.app.model.Product2;

public class DateToString {

	public static void main(String[] args) throws IOException {

		DozerBeanMapper mapper = new DozerBeanMapper();
		mapper.setMappingFiles(Arrays.asList("date_to_string.xml"));

		Product1 product1 = new Product1();
		product1.setManufacturingDate(new Date());

		Product2 product2 = mapper.map(product1, Product2.class);
		Product1 product1ConvertedBack = mapper.map(product2, Product1.class);

		System.out.println(product1);
		System.out.println(product2);
		System.out.println(product1ConvertedBack);

	}

}

 

Output

Product1 [manufacturingDate=Sun Feb 06 19:30:15 IST 2022]
Product2 [dateString=02/06/2022 19:30:15:636]
Product1 [manufacturingDate=Sun Feb 06 19:30:15 IST 2022]
