I'm sorry, but I'm not quite sure what you're asking. Are you looking for a tutorial on how to send messages through a Java-based WeChat public account, along with the source code? If so, I can certainly help you with that.To get started, you'll need to have a WeChat public account set up and registered as a developer. Once you have that, you can use the WeChat API to send messages to your subscribers.There are a few different libraries and frameworks you can use to interact with the WeChat API in Java, such as Weixin Java Tools and WeChat Java SDK. Depending on which one you choose, the implementation details may vary slightly, but the basic steps will be the same:
1. Authenticate with the WeChat API using your app ID and app secret.
2. Create a message object with the content you want to send.
3. Send the message to your subscribers using the appropriate API endpoint.
I hope this helps get you started! If you have any more specific questions or need further guidance, feel free to ask.
