/**
 * 
 * Maps any given Java object on a JSON column type that is managed via {@link java.sql.PreparedStatement#setBlob(int, Blob)} at JDBC Driver level.
 * 
 * 
 * If you are using Oracle, you can use this {@link JsonBlobType} to map a {@code BLOB} column type storing JSON.
 * 
 * 
 * For more details about how to use it, check out this article on vladmihalcea.com.
 * 
 * 
 * If you want to use a more portable Hibernate Type that can work on Oracle, SQL Server, PostgreSQL, MySQL, or H2 without any configuration changes, then you should use the {@link JsonType} instead.
