Silver Networking off Payment, refund Java implementation

    It lasted two weeks and finally paid the refund for the UnionPay. Because no one to guide, went a lot of detours, bloggers here posted the relevant code, hoping to help like me, no one to guide the small partners.

Pay for UnionPay 1: Payment, refund process.

2: Pay the relevant preparation to the official website to download the SDK, the official website related address will be at the end of this article to provide download the official website of the test configuration file acp_sdk.properties, test related certificates Acp_test_enc.cer,acp_test_ SIGN.PFX, modify acp_sdk.properties after placed under Classpath, if you want to use production environment, the relevant certificate file has four, the configuration file also has corresponding production environment certificate. If the payment is successful after the jump page, you need to prepare the relevant page, if the Java code concatenation string, you need to prepare the relevant Java class, used to dynamically produce HTML pages. 3: Payment, refund related code
