How to convert java.util.Map To Java Bean?

Java Bean Components Java 

Following example shows how to populate a Java Bean fields from java.util.Map.

Example

package com.logicbig.example;

public class Person {
    private String name;
    private int age;
    private String address;

    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 getAddress() {
        return address;
    }

    public void setAddress(String address) {
        this.address = address;
    }

    @Override
    public String toString() {
        return "Person{" +
                "name='" + name + '\'' +
                ", age=" + age +
                ", address='" + address + '\'' +
                '}';
    }
}

package com.logicbig.example;

import java.lang.reflect.Field;
import java.util.HashMap;
import java.util.Map;

public class MapToBeanUtil {

    public static void main(String[] args) {
        Map<String, Object> map = new HashMap<>();
        map.put("name", "Tina");
        map.put("age", 30);
        map.put("address", "101 Sun Street, Yellow Town");
        Person person = toBean(map, Person.class);
        System.out.println(person);
    }

    public static <T> T toBean(Map<String, Object> beanPropMap, Class<T> type) {
        try {
            T beanInstance = type.getConstructor().newInstance();
            for (Object k : beanPropMap.keySet()) {
                String key = (String) k;
                Object value = beanPropMap.get(k);
                if (value != null) {
                    try {
                        Field field = type.getDeclaredField(key);
                        field.setAccessible(true);
                        field.set(beanInstance, value);
                        field.setAccessible(false);
                    } catch (Exception e) {
                        e.printStackTrace();

                    }
                }
            }
            return beanInstance;
        } catch (Exception e) {
            e.printStackTrace();
        }
        return null;
    }
}

Person{name='Tina', age=30, address='101 Sun Street, Yellow Town'}
