Java (server side)-Integrated UnionPay payment, including code

Baidu UnionPay pay, basic in the spray UnionPay code rotten, or to take the official code posted up, are not careful to say the integration process, the use is not very much here to record my integration process, I hope to help everyone Official DemoIt is said that the UnionPay code has no specifications and the documents are rotten. But others very attentively, provided the demo, a little modification can be directly run. If you do not want to see this step, skip directly, but the demo still has to be downloaded ., we want to use the inside code demo download address: https://open.unionpay.com/ajweb/index, help center > Download > Gateway payment > Gateway Payment Leveling Technology Development PackageImport Eclipse, copy the certificate inside the src/assets/test environment certificate to E:/certs, (the latest version is 4 files, regardless of that version, the files are copied, and so will be modified on the line) modify Acp_ Sdk.properties, change the following to the address of the file just copied
Acpsdk.signcert.path=e:/certs/acp_test_sign.pfx
Acpsdk.encryptcert.path=e:/certs/acp_test_enc.cer

Launch, publish to Tomcat, browser run LOCALHOST:8080/ACPSAMPLE_B2C initiate request, try more, be familiar with logic Start Integration Payment ProcessFront end request own server, own server request UnionPay, set the URL of a background notification, get the TN front end to take TN payment front-end payment completed, the Bank of the Federation tune you set the URL, and give you the corresponding parameters in the background according to the parameters of UnionPay, verify the signature, according to the corresponding business logic to judge add gold coins Copy the SDK package in the demo to your project

Config,unionpaycontroller,unionpayservice I wrote it myself, config is Com.unionpay.acp.demo under the Demobase get TN

The front end of the user ID, product ID passed over
Code as follows, to be modified where the TODO is written

Front end take the TN payment, slightly the interface of the UnionPay callback

Reference Com.unionpay.acp.demo.BackRcvResponse here
here is the pit : UnionPay tune your interface, 1. Must be extranet, 2. If you return to the status code is 200, it does not continue to tune, if not 200, he will continue to tune your interface, which is where I have thrown anomalies, and some places to return directly to the reason
