在java中覆盖内部方法之前执行外部方法 [英] outer method execute before override inside method in java

问题描述

目前正在尝试使用来自 response.body() 的 JSON 数据来设置 User u 对象(改造).但是，我无法做到这一点.loginOperation(email,psswd) 返回一个布尔值，表明是否成功登录.当我尝试执行此外部方法时，它会在覆盖方法 onResponse() 之前返回 check.

Currently trying to set User u object by using JSON data from response.body() (retrofit). However, I am not able to do that. loginOperation(email,psswd) returns a boolean value which states whether a successful logged-in or not. When I try to execute this outer method, it returns check before the overridden method onResponse().

有什么建议吗?提前致谢！

Is there any advice? Thanks in advance!

AuthenticationCheck 类 ----------

public class AuthenticationCheck {

RetrofitConnection rc = new RetrofitConnection();
Retrofit retrofit = rc.getRetrofit();
private static boolean check = false;
private static User u = new User();


synchronized public boolean loginOperation(String email, String password){

    LoginService loginService = retrofit.create(LoginService.class);
    Call<ResponseBody> call = loginService.loginWithCredentials(new 
LoginCredentials(email, password));
    call.enqueue(new Callback<ResponseBody>() {

        @Override
        synchronized public void onResponse(Call<ResponseBody> call, Response<ResponseBody> response) {

            if (response.isSuccessful()) {
                check=true;
                final JSONObject obj;
                try {
                    obj = new JSONObject(response.body().string());
                    final JSONObject userObj =  obj.getJSONObject("user");
                    u.setSurname(userObj.getString("surname"));
                    u.setPhone(userObj.getString("phonenumber"));
                    u.setUser_id(userObj.getInt("user_id"));
                    u.setName(userObj.getString("name"));
                    u.setEmail(userObj.getString("email"));

                } catch (JSONException e) {
                    e.printStackTrace();
                } catch (IOException e) {
                    e.printStackTrace();
                }

            }

        }

        @Override
        synchronized public void onFailure(Call<ResponseBody> call, Throwable t) {
            Log.e("FAIL","onFailure ");

        }
    });
return check;

}

public String getEmail() { return email; }

public String getName() { return name; }

public String getPasswd() { return password; }

public String getPhone() { return phone; }

public String getSurname() { return surname; }

public int getUser_id() { return user_id; }

public void setEmail(String email) {

}

public void setSurname(String surname) {
    this.surname = surname;
}

public void setUser_id(int user_id) { this.user_id = user_id; }

@Override
public String toString() {
    return "Post{" +
            "user_id='" + user_id + '\'' +
            ", name='" + name + '\'' +

推荐答案

使用 Rest Template 而不是你的调用，这将是一个被阻止的 http 调用，参见 这里的例子

Use Rest Template instead of your call, it will be a blocked http call, see examples here
