Mule ESB Primer, the simplest Hello instance

This is one of the simplest examples of mule ESB entry, with Flow, endpoint, transformer,component these components, which are also the simplest to configure.

Scene:

1. Enter http://localhost:9090/hello-mule?name=oliver&age=20 in the browser address bar to return "Hello Oliver,your age is 10".

1. Enter HTTP://LOCALHOST:9090/LOVE-MULE?NAME=OLIVER&AGE=20 in the browser's address bar to return "Love Oliver,your-is 10".
