1, environment configuration
Micro-service architecture using SpringCloud technology stack technology, including:
distributed configuration center: SpringCloudConfig Version: 2.0.1
Service Discovery and Registration Center: Eureka Version: 1.4.3
inter-service load balancing: OpenFeign Version: 2.0.1
fuse mechanism: hystrix version: 1.3.1
here we must note: when using SpringBoot and SpringCloud there is a version matching relation:
| Spring Boot | Spring Cloud |
|---|---|
| 1.2.x | Angel version |
| 1.3.x | Brixton Version |
| 1.4.x stripes | Camden version |
| 1.5.x | Dalston version, Edgware version |
| 2.0.x | Finchley version |
My father then used in the project is version 2.0.0 of springboot, and Finchley version of springcloud.
2, Alipay Interface Application (sandbox environment)
Here declare it: Alipay actual environment requires businesses operating license verification, so here I personally just use the sandbox environment.
Refer to this blog specific process: how the next micro-architecture integrated service Alipay payment service interface (VI) Alipay Interface (sandbox environment) application
3, the project to build
Since these modules are a small a project, set up process is relatively complex, written in the articles in the crowded, so we divided the articles.
Micro services using maven build.
The directory structure follows
the parent project: blog packaged form pom
remaining sub-projects, all packaged into a jar package. (Of course, if you want to use an external tomcat clustered configuration, that is, consumers need to be inside my blog-security packaged into war package)
(1) Set up the configuration center config
Refer to this blog specific process: how the next micro-architecture integrated service Alipay payment service interface (b) the use SpringCloudConfig to build distribution center
(2) build a service registry eureka
Refer to this blog specific process: how the next micro-architecture integrated service Alipay payment service interface (three) combined distribution center structures eureka service registry
(3) Add Alipay api-related entity classes
Here are some of the main parameters of the request to package alipay, parameters and return values.
AlipayBizParameters all the necessary parameters are uploaded to the package when the transmission request. (In addition to the configuration parameters)
AlipayNotifyUrlParameters all the parameters are returned to the asynchronous package.
Specific parameters description can be found in Alipay's official website:
Upload parameters: https://docs.open.alipay.com/api_1/alipay.trade.precreate/
asynchronous return values: https://docs.open.alipay.com/ 270/105 902 /
