First Example
Creating an admin page with Erupt is extremely simple — a single Java class is all you need:
java
package xyz.erupt.example.model;
import org.hibernate.annotations.GenericGenerator;
import xyz.erupt.annotation.Erupt;
import xyz.erupt.annotation.EruptField;
import xyz.erupt.annotation.sub_field.Edit;
import xyz.erupt.annotation.sub_field.View;
import javax.persistence.*;
// @Erupt goes on the class, @EruptField goes on each field. The rest are standard JPA annotations.
@Erupt(name = "Simple Example")
@Table(name = "demo_simple")
@Entity
public class Simple {
// Primary key
@Id
@GeneratedValue(generator = "generator")
@GenericGenerator(name = "generator", strategy = "native")
@Column(name = "id")
@EruptField
private Long id; // No need to redeclare id if you extend BaseModel
// Text input
@EruptField(
views = @View(title = "Text"),
edit = @Edit(title = "Text")
)
private String input;
// Numeric input
@EruptField(
views = @View(title = "Number"),
edit = @Edit(title = "Number")
)
private Integer number = 100; // default value 100
// Boolean switch
@EruptField(
views = @View(title = "Boolean"),
edit = @Edit(title = "Boolean")
)
private Boolean bool;
// Date picker
@EruptField(
views = @View(title = "Date"),
edit = @Edit(title = "Date")
)
private Date date;
}After starting the project, simply bind the class to a menu. Steps:
How to bind: log in, go to System Management → Menu Management, click Add, set the menu type to Table, the type value to Simple, save and refresh — the menu is now accessible.
The database schema and column comments are generated automatically:

Erupt supports more than 23 categories of components for flexible configuration.
In real-world development, only the @Erupt and @EruptField annotations are required to get started.
