Spring: Using builder pattern to create a bean

Question

I use ektorp to connect to CouchDB.

The way to build an ektorp HttpClient instance is to use builder pattern:

HttpClient httpClient = n         


        

Answer 1

While FactoryBean is cleaner there is a more quick-n-dirty method, using SpEL.

This is how I've just configured the Neo4j driver:

As you can see from the factory method's 3rd parameter, you can invoke a builder and its methods as a SpEL expression, with the nuance that classes have to be specified via their FQN. But that avoids you to write an entire boilerplate FactoryBean.
