如何将numeric(13，3)[]数据库列映射到Hibernate实体字段？

@Column(name = "column_name")
@Type(type = "numeric-array", parameters = {
    @Parameter(name = "precision", value = "13"),
    @Parameter(name = "scale", value = "3")
})
private BigDecimal[] columnName;

public class NumericArrayUserType implements UserType {

    // 省略其他方法

    @Override
    public int[] sqlTypes() {
        return new int[] { Types.ARRAY };
    }

    @Override
    public Class returnedClass() {
        return BigDecimal[].class;
    }

    @Override
    public Object nullSafeGet(ResultSet rs, String[] names, SessionImplementor session, Object owner) throws SQLException {
        Array array = rs.getArray(names[0]);
        if (array != null) {
            BigDecimal[] values = (BigDecimal[]) array.getArray();
            return values;
        }
        return null;
    }

    @Override
    public void nullSafeSet(PreparedStatement st, Object value, int index, SessionImplementor session) throws SQLException {
        if (value != null) {
            BigDecimal[] values = (BigDecimal[]) value;
            Array array = session.connection().createArrayOf("numeric", values);
            st.setArray(index, array);
        } else {
            st.setNull(index, Types.ARRAY);
        }
    }
}
