springboot整合微信公众号

Spring Boot 可以很方便地与微信公众号进行整合。下面是一个 Spring Boot 整合微信公众号的简单步骤：

1.创建一个微信公众号并获取 AppID 和 AppSecret。

2.在 pom.xml 中添加以下依赖：

<dependency>
   <groupId>com.github.sd4324530</groupId>
   <artifactId>weixin-java-tools-spring-boot-starter</artifactId>
   <version>2.9.0</version>
</dependency>

3.在 application.properties 中配置 AppID 和 AppSecret：

wechat.appId=yourAppId
wechat.appSecret=yourAppSecret
wechat.token=yourToken
wechat.aesKey=yourAesKey

4.创建一个类来配置微信公众号：

@Configuration
public class WechatConfig {

   @Autowired
   private WechatProperties wechatProperties;

   @Bean
   public WxMpConfigStorage wxMpConfigStorage(){
       WxMpInMemoryConfigStorage configStorage = new WxMpInMemoryConfigStorage();
       configStorage.setAppId(wechatProperties.getAppId());
       configStorage.setSecret(wechatProperties.getAppSecret());
       configStorage.setToken(wechatProperties.getToken());
       configStorage.setAesKey(wechatProperties.getAesKey());
       return configStorage;
   }

   @Bean
   public WxMpService wxMpService(WxMpConfigStorage wxMpConfigStorage){
       WxMpService wxMpService = new WxMpServiceImpl();
       wxMpService.setWxMpConfigStorage(wxMpConfigStorage);
       return wxMpService;
   }

}

5.在 Controller 中处理微信公众号的消息：

@RestController
@RequestMapping("/wechat")
public class WechatController {

   @Autowired
   private WxMpService wxMpService;

   @GetMapping(produces = "text/plain;charset=utf-8")
   public String authGet(@RequestParam(name = "signature", required = false) String signature,
                         @RequestParam(name = "timestamp", required = false) String timestamp,
                         @RequestParam(name = "nonce", required = false) String nonce,
                         @RequestParam(name = "echostr", required = false) String echostr) {
       if (!wxMpService.checkSignature(timestamp, nonce, signature)) {
           return "非法请求";
       }
       return echostr;
   }

   @PostMapping(produces = "application/xml; charset=UTF-8")
   public String post(@RequestBody String requestBody,
                       @RequestParam("signature") String signature,
                       @RequestParam("timestamp") String timestamp,
                       @RequestParam("nonce") String nonce,
                       @RequestParam("openid") String openid,
                       @RequestParam(name = "encrypt_type", required = false) String encType,
                       @RequestParam(name = "msg_signature", required = false) String msgSignature) {
       if (!wxMpService.checkSignature(timestamp, nonce, signature)) {
           throw new IllegalArgumentException("非法请求，可能属于伪造的请求！");
       }

       WxMpXmlMessage wxMessage;
       if (encType == null) {
           wxMessage = WxMpXmlMessage.fromXml(requestBody);
       } else {
           wxMessage = WxMpXmlMessage.fromEncryptedXml(requestBody, wxMpService.getWxMpConfigStorage(), timestamp, nonce, msgSignature);
       }

       String content = "收到消息内容：" + wxMessage.getContent();
       WxMpXmlOutMessage outMessage = WxMpXmlOutMessage.TEXT().content(content).fromUser(wxMessage.getToUser())
               .toUser(wxMessage.getFromUser()).build();
       return outMessage.toXml();
   }

}

现在你就可以通过该 Controller 处理微信公众号的消息了。
