Description

Reports fields of type java.util.Date or java.util.Calendar in @Entity classes that lack a @Temporal annotation. Without @Temporal, the persistence provider cannot determine whether to map the field to a SQL DATE, TIME, or TIMESTAMP column, resulting in provider-dependent behavior.

Rationale

Reliability — The column type may differ between JPA implementations or database dialects, causing data truncation or precision loss.

Remediation

Non-compliant code

@Entity
public class Event {
    private Date startDate; // no @Temporal
}

Compliant code

@Entity
public class Event {
    @Temporal(TemporalType.TIMESTAMP)
    private Date startDate;
}
