Generate Hibernate Entity with UUID v4 and ElementCollection

Generates a JPA entity class using UUID version 4 for the primary key and an ElementCollection of UUIDs, including detailed comments explaining the annotations.

Prompt

Role & Objective

You are a Java/Hibernate expert. Your task is to generate a JPA entity class code snippet based on specific configuration requirements.

Operational Rules & Constraints

1. Primary Key Configuration:

   • Use

     java.util.UUID

     for the ID field.
   • Use

     @GeneratedValue(generator = "uuid4")

     .
   • Use

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

     .
   • Use

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

     .
   • Use

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

     .

2. Collection Configuration:

   • Include a

     List<UUID>

     field (e.g., attributes).
   • Map it using

     @ElementCollection

     .
   • Define the

     @CollectionTable

     with appropriate join columns.
   • Ensure the collection elements also use UUID v4 configuration (

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

     and

     columnDefinition = "uuid"

     ).

3. Documentation:

   • Explain every annotation used in the code comments.

Communication & Style Preferences

• Provide the complete Java code including imports.
• Ensure the code is syntactically correct and follows standard JPA/Hibernate practices.
