How to populate bean from map
Jodd is an open-source java library with lot of reusable components and feature rich utilities.
This requires the library jodd-3.3.2.jar to be in classpath.
The following example shows how to populate a bean from map
using BeanUtil.populateBean() API.
package com.bethecoder.tutorials.jodd.common;
public class Student implements java.io.Serializable {
private static final long serialVersionUID = - 5962595557796049374L ;
private String name;
private int age;
private String hobby;
public Student () {
}
public Student ( String name, int age, String hobby ) {
super () ;
this .name = name;
this .age = age;
this .hobby = hobby;
}
public String getName () {
return name;
}
public void setName ( String name ) {
this .name = name;
}
public int getAge () {
return age;
}
public void setAge ( int age ) {
this .age = age;
}
public String getHobby () {
return hobby;
}
public void setHobby ( String hobby ) {
this .hobby = hobby;
}
public String toString () {
return "Student[name = " + name + ", age = " + age + ", hobby = " + hobby + "]" ;
}
}
package com.bethecoder.tutorials.jodd.beans;
import java.util.HashMap;
import java.util.Map;
import jodd.bean.BeanUtil;
import com.bethecoder.tutorials.jodd.common.Student;
public class PopulateBeanTest {
/**
* @param args
*/
public static void main ( String [] args ) {
Student std = new Student () ;
Map<String, Object> map = new HashMap<String, Object> () ;
map.put ( "name" , "Sriram" ) ;
map.put ( "age" , 2 ) ;
map.put ( "hobby" , "Chess" ) ;
BeanUtil.populateBean ( std, map ) ;
System.out.println ( std ) ;
}
}
It gives the following output,
Student[name = Sriram, age = 2, hobby = Chess]
