Hibernate stores blob and CLOB types of data into a database

I chose byte[] [email protected]

Just start using the Java.sql.Blob, will upload the picture GetBytes () after the Hibernate.getlobcreator (Hibernatesessionfactory.getsession ()). Createblob (New byte[] (Pic.getbytes ()));

To get the BLOB type.

You can actually get the BLOB type (Oracle. BLOB), but it needs to be obtained by means of the Resultset.getblob () of the result set obtained by the original data source and statement.

Because using hibernatetemplate or HQL statements, you don't know how to get blobs easily.

In fact, the simplest way is to define the instance variable as a blob, but you need to convert the upload file to a blob, because this type is OJDBC, and the form submission does not convert it to the corresponding JavaBean, which is difficult. BLOB solution
