Test procedure:

1. Person. java:

import java.util.List;

/**
 * Created by Administrator on 2017/5/6.
 */
public class Person {
    private int id;
    private String name;
    private List<Address> addresses;

    public int getId() {
        return id;
    }

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

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public List<Address> getAddresses() {
        return addresses;
    }

    public void setAddresses(List<Address> addresses) {
        this.addresses = addresses;
    }

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

2、Address.java:

Public class Address {
Private String name;

Public String getName (){
Return name;
}

Public void setName (String name ){
This. name = name;
}

@ Override
Public String toString (){
Return "Address {" +
"Name = '" + name +' \ ''+
'}';
}
}

3. Main Function

JsonConfig config = new JsonConfig ();
Config. setRootClass (Person. class );

Map <String, Class <?> ClassMap = new HashMap <String, Class <?> ();
ClassMap. put ("addresses", Address. class );
Config. setClassMap (classMap );

PropertyNameProcessor lowerCasePropertyNameProcessor = new PropertyNameProcessor (){
@ Override
Public String processPropertyName (Class aClass, String s ){
Return s. substring (0, 1). toLowerCase () + s. substring (1 );
}
};

Config. registerJavaPropertyNameProcessor (Person. class, lowerCasePropertyNameProcessor );
Config. registerJavaPropertyNameProcessor (Address. class, lowerCasePropertyNameProcessor );

// Convert uppercase to lowercase beans
String jsonString = "{\" Id \ ": 3, \" Name \ ": \" xiaoming \ ", \" Addresses \ ": [{\" Name \": \ "xian \"}]} ";
JSONObject jsonObject = JSONObject. fromObject (jsonString );
Person person = (Person) JSONObject. toBean (jsonObject, config );
System. out. println (person );

4. Running result
Person {id = 3, name = 'xiaoming', addresses = [Address {name = 'xian '}]}
