1.1. Introduction to the course content

This course is based on the theory and project-driven, which is suitable for the students or developers of the initial contact message receiving and sending, assembly parsing and transaction distribution. From the message specification of reading, demand refinement, to the implementation of the framework, so that the easy-to-digest explanation. The content or technology involved is: using JAXB to transform XML with JavaBean, spring3.x, Springmvc, hibernate3.x, Apache HttpClient 3.x, junit4.x, custom annotation + Java Reflection Technology completes message identification and forwarding, platform exception encapsulation and business flow records, etc.

1.2. Project Introduction

The program used by the mobile payment platform providers in response to China UnionPay Unified release of the interface message specification requirements, built between its own business platform and the UnionPay public service platform between the project. It covers hundreds of messages, from authentication, SE registration to application download, and deletion. For the sake of clarity of teaching, the simulation of some representative messages is verified.
