As a Java engineer, one of the most repetitive tasks is writing boilerplate DAO and domain classes — especially when you’re not using heavy frameworks like Spring or Hibernate.
That’s why I built Appaveli CLI— a lightweight, Dart-powered command-line tool designed to automate the creation of Java DAO and domain classes. It’s clean, fast, and perfect for developers who want full control over their backend architecture without sacrificing productivity.
✨ What Is Appaveli CLI?
Appaveli CLI is a developer tool I engineered, crafted for solo developers, startups, or lean teams who don’t want to over-engineer their backend.
With a single command, Appaveli CLI scaffolds fully-structured Java domain and DAO classes that follow clean code principles and work with basic JDBC.
No Spring. No Hibernate. No magic. Just code you can trust and control.
💡 Why I Built It
I wanted a way to rapidly generate backend code that could plug directly into my custom lightweight Java framework, without the bloat of external libraries.
I also wanted to avoid writing the same getters, setters, and JDBC statements over and over, and over, again.
⚙️ How It Works
Once installed, you can use the CLI like this:
Generate a Java domain class
`java -jar target/appaveli-cli-jar-with-dependencies.jar generate-domain \
- entity User \
- package com.example.domain \
- fields "id:int,username:String,email:String,active:boolean"`
Generate a matching DAO class with JDBC CRUD
java -jar target/appaveli-cli-jar-with-dependencies.jar generate-dao \
- entity User \
- package com.example.dao
It will create files:
🧠 What Gets Generated
User Domain:
package com.example.domain;
public class User {
private int id;
private String username;
private String email;
private boolean active;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
public boolean getActive() {
return active;
}
public void setActive(boolean active) {
this.active = active;
}
@Override
public String toString() {
return "User{" +
"id='" + id + '\'' +
"username='" + username + '\'' +
"email='" + email + '\'' +
"active='" + active + '\'' + '}';
}
}
UserDao:
package com.example.dao;
import java.util.List;
import tech.appavelitech.domain.User;
public interface UserDao {
void save(User entity);
User findById(int id);
List<User> findAll();
void update(User entity);
void delete(int id);
}
UserDaoImpl:
package com.example.dao;
import java.util.*;
import tech.appavelitech.domain.User;
public class UserDaoImpl implements UserDao {
@Override
public void save(User entity) {
// TODO: Implement
}
@Override
public User findById(int id) {
// TODO: Implement
return null;
}
@Override
public List<User> findAll() {
// TODO: Implement
return new ArrayList<>();
}
@Override
public void update(User entity) {
// TODO: Implement
}
@Override
public void delete(int id) {
// TODO: Implement
}
}
