9.10 Extending the Spider


So far, the Spider meets the needs the


original
client. We have provided all of the necessary functionality in a
simple, efficient package. The user interfaces are nicely decoupled
from the business logic, meaning we can extend the application into
multiple other interface areas. Since we have designed the
application with the idea of extensibility through transparency, we
ought to be able to add other services fairly easily.

In the next chapter, we're going to see how easy it
is to repurpose the spider for use in a different context.
We'll replace the existing search functionality in
the jPetStore sample application with the Simple
Spider. This process demonstrates how following the principlels laid
out in this book make it easy to reuse your code and make it work in
new contexts. We'll layer our standalone application
into a Spring framework with minimal changes to the original code.
