JPA中核心類型（String、Integer等）集合的映射

public class SingleChoiceField {
	private Long id;
	private Set<String> provideValues;

	@Id
	@GeneratedValue
	public Long getId() {
		return id;
	}

	public void setId(Long id) {
		this.id = id;
	}

	@CollectionOfElements
	@JoinTable(name = "SingleChoiceFieldProvideValue", joinColumns = @JoinColumn(name = "fieldId"))
	public Set<String> getProvideValues() {
		return provideValues;
	}

	public void setProvideValues(Set<String> provideValues) {
		this.provideValues = provideValues;
	}
}
