Json schema to Java entity class

I am a java client developer. We have a requirement of generating java entity class from json schema. Although Json schema to pojo is possible through multiple libraries ( https://www.jsonschema2pojo.org/ ), our requirement is from Json schema to JPA entity class.

Can we use dynamic proxy to generate this

Json:

{

  "properties" : {
    "id" : {
      "type" : "string"
    },
    "lock" : {
      "type" : "string"
    },
    "version" : {
      "type" : "integer"
    }
  }
}

Java entity class

package com.testclient;

import java.util.Objects;

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.Id;
import javax.persistence.Table;
import javax.persistence.Transient;
import javax.persistence.Version;



@Entity
@Table(name = "DUMMYMODEL")
public class DummyModel implements Model<String> {
    @Id
    private String id;

    @Version
    private Long version;

    @JsonIgnore
    @Transient
    private String lock;

    public DummyModel() {
    }

    public DummyModel(String id) {
        this.id = id;
    }

    @Override
    public String getId() {
        return id;
    }

    @Override
    public Long getVersion() {
        return version;
    }

    @Override
    public String getLock() {
        return lock;
    }

    @Override
    public void setVersion(Long version) {
        this.version = version;
    }

    @Override
    public void setLock(String lock) {
        this.lock = lock;
    }

  
    @Override
    public String toString() {
        return "DummyModel [id=" + id + ", version=" + version + ", lock=" + lock + "]";
    }
}

Am aware of https://www.jsonschema2pojo.org/ which generates pojo.
