Basic

```
@Target({METHOD,FIELD})
@Retention(RUNTIME)
public @interface Basic
```
The simplest type of mapping of a persistent field or property to a single database column.
The Basic annotation may be applied to a property or instance variable whose type is any one of the following:
- a Java primitive type, or wrapper of a primitive type,
- String,
- BigInteger or BigDecimal,
- LocalDate, LocalTime, LocalDateTime, OffsetTime, OffsetDateTime, Instant, or Year
- Date or Calendar,
- java.sql.Date, java.sql.Time, or java.sql.Timestamp,
- byte[] or Byte[], char[] or Character[],
- a Java enum type, or
- any other serializable type.
The use of the Basic annotation is optional for persistent fields and properties of these types. If the Basic annotation is not specified for such a field or property, the default values of the Basic annotation apply.
The database column mapped by the persistent field or property may be specified using the Column annotation.

```
FetchType fetch
```
    (Optional) Whether the value of the field or property should be lazily loaded or must be eagerly fetched.
    
    The EAGER strategy is a requirement on the persistence provider runtime that the associated entity must be eagerly fetched.
    The LAZY strategy is a hint to the persistence provider runtime.
    
    If not specified, defaults to EAGER.
    Default:
    
    jakarta.persistence.FetchType.EAGER
- - optional
```
boolean optional
```
    (Optional) Specifies whether the value of the field or property may be null.
    This is a hint and is disregarded for primitive types; it may be used in schema generation to infer that the mapped column is not null.
    If not specified, defaults to true.
    
    Default:
    
    true
