Mysql 在hibernate注释中设置srid

我想为点添加索引,但mysql向我发出警告:
查询优化器不会使用列“point”上的空间索引,因为该列没有SRID属性。考虑向列中添加SRID属性。
如何将srid属性添加到带注释的点,以及如何将空间索引添加到带注释的点。使用列定义进行尝试。使用Hibernate 5.4.2和MySQL 8.0进行测试
@Entity
public class GeometryEntity {
@Id
@GeneratedValue
private Long id;
// only allow geometries with SRID 4326 and not null (be able to create spatial indexes)
@Column(nullable = false, columnDefinition = "GEOMETRY SRID 4326")
private Geometry geometry;
private void setId(final Long id) {
this.id = id;
}
public Long getId() {
return id;
}
public void setGeometry(final Geometry geometry) {
this.geometry = geometry;
}
public Geometry getGeometry() {
return geometry;
}
}
