For java.sql.Types.BLOB, I use the builder.value(Object object) method in XContentBuilder, with a byte array as parameter.
For java.sql.Types.CLOB/NCLOB, I use just a string as returned by JDBC in Clob.getSubString There are DBs which store blobs as java.sql.Types.BINARY, and this can be passed as string or byte array to XContentBuilder (default is byte array). Here, it is a NVARCHAR column of MS SQL, which is alway returned by JDBC as string by the getNString() method.
