WxJava

WxJava is a Java SDK for WeChat backend development. Separate modules cover official accounts, mini programs, payment, enterprise WeChat, the open platform, and video accounts and shops.

The README starts with a table that maps a business scenario to a module. WeChat official account development points to MP with the artifact weixin-java-mp. Mini programs map to MiniApp and weixin-java-miniapp, payment to Pay and weixin-java-pay, enterprise WeChat to CP, the open platform to Open, and video accounts or shops to Channel. For mobile apps, a note clarifies that client integration still uses the official iOS and Android SDKs, while this project stays on the server side.

The README is blunt that this is an SDK toolkit, not a web implementation, and recommends pulling it in with Maven or Gradle. Multi-module projects are pointed at a BOM called wx-java-bom, available from version 4.8.3.B, to keep versions in one place. Compilation relies on Lombok, so the docs suggest learning that first. The minimum JDK is 8, with older JDK 7 users directed to WxJava 3.8.0 and earlier.

Formal versions come out roughly every six months, with quick timestamp-based builds after each code change. When a formal version is released, the develop branch merges into release and versions take the X.X.0 shape, while test versions carry a B suffix. The README points at 4.8.0 as the latest formal release and links per-module version lookups.

The development wiki holds a FAQ that beginners are told to read before opening issues. Javadoc is hosted online for modules including weixin-java-miniapp, weixin-java-pay, weixin-java-mp, weixin-java-common, weixin-java-cp, and weixin-java-open. The project also notes a GitCode 2024 award for top ten open source communities, and there are QQ, WeChat, and DingTalk groups with a code of conduct that asks people to search before asking.
