为什么运行springboot demo时，提示404

fishinhouse commented 7 years ago

输出的日志信息： o.s.w.s.m.m.a.HttpEntityMethodProcessor : Written [{timestamp=Fri Mar 03 04:27:07 CST 2017, status=404, error=Not Found, message=No message available, path=/wechat/portal}] as "application/json;charset=UTF-8" using [org.springframework.http.converter.json.MappingJackson2HttpMessageConverter@53605dd] o.s.web.servlet.DispatcherServlet : Null ModelAndView returned to DispatcherServlet with name 'dispatcherServlet': assuming HandlerAdapter completed request handling o.s.web.servlet.DispatcherServlet : Successfully completed request

Controller代码：

@RestController
@RequestMapping("/wechat/portal")
public class WechatController {
private final Logger logger = LoggerFactory.getLogger(this.getClass());

@Autowired
private WxMpService wxService;

@Autowired
private WxMpMessageRouter router;

@ResponseBody
@RequestMapping(method=RequestMethod.GET,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) {

    this.logger.info("\n接收到来自微信服务器的认证消息：[{}, {}, {}, {}]", signature,
        timestamp, nonce, echostr);

    if (StringUtils.isAnyBlank(signature, timestamp, nonce, echostr)) {
        throw new IllegalArgumentException("请求参数非法，请核实!");
    }

    if (this.wxService.checkSignature(timestamp, nonce, signature)) {
        return echostr;
    }

    return "非法请求";
}

运行就报404？不可能吧，只能是你访问了某个错误的地址才导致的吧，请正确描述下你的操作过程吧

网上也有类似404问题： http://www.imooc.com/qadetail/150764

binarywang commented 7 years ago

从你发出来的内容看不出来什么。首先你没理解404的含义，是指没找到对应的请求路径，你先跑下本demo后，试图理解后，再看看你自己的程序到底哪儿出了问题。

fishinhouse commented 7 years ago

问题找到了，自己添加的Controller和启动自动加载的一些组件目录都要在“com.github.binarywang.demo.wechat”这个包下面，不然可以正常启动，调用时会出现404问题。
