ExWechat是一个java编写的微信类库。 Maven项目3步整合微信。

1. 加入Repository。

<repository>
    <id>ExWechat-mvn-repo</id>
    <url>https://raw.github.com/ericxu131/ExWechat/mvn-repo/</url>
    <snapshots>
        <enabled>true</enabled>
        <updatePolicy>always</updatePolicy>
    </snapshots>
</repository>

2. 加入Rependency。

<dependency>
    <groupId>com.ericxu131</groupId>
    <artifactId>EXWechat</artifactId>
    <version>1.0-SNAPSHOT</version>
    <exclusions>
        <exclusion>
            <artifactId>javax.servlet-api</artifactId>
            <groupId>javax.servlet</groupId>
        </exclusion>
    </exclusions>
</dependency>

3. 新建一个Servlet继承WechatServlet来接收微信的信息。

import com.ericxu131.exwechat.WechatClient;
import com.ericxu131.exwechat.model.WechatUser;
import com.ericxu131.exwechat.model.event.ClickEvent;
import com.ericxu131.exwechat.model.message.Message;
import com.ericxu131.exwechat.model.message.TextMessage;
import com.ericxu131.exwechat.web.WechatServlet;
import javax.servlet.annotation.WebServlet;

/**
 *
 * @author eric
 */
@WebServlet(name = "MyWechatServlet", urlPatterns = {"/MyWechatServlet"})
public class MyWechatServlet extends WechatServlet {

    @Override
    protected String getToken() {
        return "这里填写token";
    }

    @Override
    protected Message onMessage(Message message) {
        //接收文本信息
        if (message instanceof TextMessage) {
            TextMessage textMessage = (TextMessage) message;
            if ("hi".equals(textMessage.getContent())) {
                //创建回复的信息
                TextMessage responseMessage = replyTextMessage(message);

                //创建一个Client来获取用户信息，这里要填写appid和secret
                WechatClient wechatClient = new WechatClient("appid", "secret");
                //获取用户信息
                WechatUser wechatUser = wechatClient.getUserInfo(message.getFromUserName());
                responseMessage.setContent(String.format("Hi:%s", wechatUser.getNickname()));
                return responseMessage;
            }
        }
        //接收自定义菜单点击事件
        if (message instanceof ClickEvent) {
            ClickEvent clickEvent = (ClickEvent) message;
            if ("V1001_XXX".equals(clickEvent.getEventKey())) {
                //处理逻辑写在这里
            }
        }
        return null;
    }

}
