需要跨域的Controller继承这个类，就可以实现跨域了。

前端实现

//全局变量
Vue.prototype.baseUrl = "http://IP地址:81/";

//封装axios
const instance = axios.create({
  baseURL: Vue.prototype.baseUrl,
  timeout: 10000,
  withCredentials: true,//跨域
  headers: {
    "Content-Type": "application/x-www-form-urlencoded"
  }//跨域
});

Vue.prototype.axios = instance;

  var rh = new Object();
      rh.ReqId = "ls123";
      rh.Salt = "sssseee";
      var rb = new Object();
      rb.CatId = "00001";

      this.axios({
        method: "post",
        url: "zdm/AppApi/Search/CategoryList",
        data: {
          ReqHead: rh,
          ReqBody: rb
        }
      })
        .then(function(response) {
          _this.msg = response;
        })
        .catch(function(error) {
          console.log(error);
        });
