Java development of micro-channel public number

The text as a reply to explain the case was related to Java development micro-channel public number.

First, there must be a personal micro-channel public number

Limited number of individual micro-channel public authority related to the interface, but for personal study and experience enough, as shown:

 

 Then enter the micro-channel public background, click the basic configuration in accordance with the following operation (click enabled, to a setting request url to their background):

 

 

Setting server URL, a token, a message encryption key (this can be automatically generated using):

 

 

Server URL is critical, I'm here to set up my own domain name http://www.youcongtech.com/wx-api.

The wx-api is behind the corresponding interfaces (for example, I send a keyword, the corresponding return information).
token can set more complex.

 The above demonstrates the effect of micro-channel public number from the person, and long-term stable operation without any problems

The complete code

The complete code has been put my personal GitHub repository, address: https://github.com/developers-youcong/blog-springcloud-pro/tree/master/blog-wx-client

This is one of the sub-project, the main function of micro-channel public platform.

In view of the open source project my personal primary maintenance were not disclosed, there are a lot of private information and so on, so will be one of the public micro-channel number of the module extracted into my new open source project blog-springcloud-pro (for this project is currently under development).

Public micro-channel number of the module substantially put his token, appid, appsecret and deployed to the basic line available. Have any questions, you can leave a message.
