3使用
@RestController
@RequestMapping("/mq")
public classMqRabbitController {
@Autowired
privateRabbitMqSenderrabbitMqSender;
@RequestMapping("/mq/send/{gameType:^.*$}/{appid:^\\d$}")
@ResponseBody
publicObject send(@PathVariableString gameType,@PathVariableString appid){
rabbitMqSender.send(JSONObject.toJSONString(wxPayRequest), 0);
}
}
