Example with declarative management of transactions for Spring Tx or Java EE

[cardil]

Spring Tx and Java EE implements declarative management of transactions via aspects and interceptors respectively.

Spring:

@Transactional
public String getUserName(int userId) {
  // [..]
}

There should be example here on how to implement an aspect or interceptor that manages transaction on method level, and how to integrate is with rxjava-jdbc, without explicitly invoking methods like dependOn()

Sounds interesting, can you provide an example of what the rxjava-jdbc api would look like with that approach?
