Since I am a local test, you need a domain name mapping tool, change the tool very simple to use, if they have a domain name you can use your own domain name (domain name must own the record) if not you can enter your own domain name prefix in the first input box inside! Micro-channel authorization must login port 80, and then click either the background map!

Tools Download: point I downloaded
Here is how to configure the domain name, the domain name needs to complete the configuration after a MP_verify_xK4DtJdHxlgIHIju.txt into the project root directory

/**
  * 配置微信文件
  */
 @GetMapping(value = "/MP_verify_xK4DtJdHxlgIHIju.txt")
 @ResponseBody
 public String config() {
     return "xK4DtJdHxlgIHIju121";
 };

Specific configuration domain view the following connection:

@GetMapping(value = "/wxLogin")
    public String get() {
        String url = wx_token_url + "appid=" + wx_appid + "&redirect_uri=" + wx_redirect_url + "&response_type=code&scope=snsapi_userinfo&state=123#wechat_redi";
        return "redirect:" + url;
