How to index a text field in Hibernate?

Question

MySQL

If we want to index a field (column) of a table using Hibernate, we write:

@Entity
@Table(name = "page", indexes = {@Index(columnList = "path", name = "path_indx")})
public class Page {
......
@Column(name = "path", columnDefinition = "TEXT", nullable = false)
@Type( type = "org.hibernate.type.TextType")
@NotNull
String path; код

but if the field is text, to index text fields (in MySQL) you must explicitly specify the length of the indexed prefix (the number of characters from the beginning of the record on which to build the index). Can't find syntax how to specify prefix length in Hibernate for text field.
