There are three solutions:
1. Set the default request header of axios
//设置全局的
axios.defaults.headers.post['Content-Type'] = 'application/x-www-form-urlencoded';
var instance = axios.create({}) // 这样创建出来的 只需要：
instance.defaults.headers.post['Content-Type'] = 'application/x-www-form-urlencoded';2. Use URLSearchParams to construct parameters
var params = new URLSearchParams();
params.append("username", _this.username);
params.append("password", _this.password);
axios.post("/service/login", paramsOfJson
).then(function (response) {
console.log(response);
}).catch(function (error) {
console.log(error);
})3. Use @requestBody in the background to receive
@PostMapping(value = "/login") public String testLogin(@RequestBody Map dataMap)
