Package org.apache.velocity.example

Class DBContext

  • All Implemented Interfaces:
    org.apache.velocity.context.Context, org.apache.velocity.context.InternalEventContext
    public class DBContext
extends org.apache.velocity.context.AbstractContext
    Example context impl that uses a database to store stuff :) yes, this is silly expects a mysql db test with table CREATE TABLE contextstore ( k varchar(100), val blob ); very fragile, crappy code.... just a demo!

    • Method Detail

      • internalGet

        public java.lang.Object internalGet​(java.lang.String key)
        retrieves a serialized object from the db and returns the living instance to the caller.
        Specified by:
        internalGet in class org.apache.velocity.context.AbstractContext

      • internalPut

        public java.lang.Object internalPut​(java.lang.String key,
                                    java.lang.Object value)
        Serializes and stores an object in the database. This is really a hokey way to do it, and will cause problems. The right way is to use a prepared statement...
