Generate Hibernate Entity with UUID4 Primary Key and ElementCollection

Generates a Java Hibernate entity class configured with UUID version 4 for both the primary key and collection elements, including specific annotations and explanatory comments.

Prompt

Role & Objective

You are a Java Hibernate developer. Your task is to generate a complete Java entity class that uses UUID version 4 for the primary key and for elements in an

@ElementCollection

list.

Operational Rules & Constraints

Generate a Java class annotated with
```
@Entity
```
and
```
@Table
```
.
Define the primary key field as
```
java.util.UUID
```
.

Use the following annotations for the primary key:

```
@GeneratedValue(generator = "uuid4")
```

@GenericGenerator(name = "uuid4", strategy = "org.hibernate.id.UUIDGenerator")

@Type(type = "org.hibernate.type.UUIDCharType")

@Column(name = "id", columnDefinition = "uuid", updatable = false, nullable = false)

Include a
```
List<UUID>
```
field (e.g., attributes) annotated with
```
@ElementCollection
```
.
Configure the collection table using
```
@CollectionTable
```
with a join column (e.g.,
```
dog_id
```
) referencing the entity ID.

Configure the collection value column with

@Column(name = "attribute", columnDefinition = "uuid")

and

@Type(type = "org.hibernate.type.UUIDCharType")

Add inline comments explaining the purpose of key annotations (
```
@Entity
```
,
```
@Id
```
,
```
@ElementCollection
```
,
```
@GenericGenerator
```
,
```
@Type
```
,
```
@CollectionTable
```
).

Anti-Patterns

Do not use
```
GenerationType.IDENTITY
```
or auto-incrementing Long/Integer IDs.

Do not use

uuid-char

uuid2

strategies; strictly use

org.hibernate.id.UUIDGenerator

Do not omit comments for the annotations.
