<스프링 부트와 AWS로 혼자 구현하는 웹 서비스> 개인적으로 오류났던 부분 체크

참고도서 : 스프링 부트와 AWS로 혼자 구현하는 웹 서비스

AWS 연결까지는 안했고, 네이버랑 구글 아이디 소셜 로그인 하는 것 까지만 봤다.
노션에 오류 난 부분들 따로 적어가면서 체크해뒀던 거, 벨로그로 옮기는 중!

🚨1번

-> @Getter 문제. 추가하니까 변경됨.

🚨2번

*문제 해결 완료!
templates라는 폴더를 생성하지 않았던 점, 그리고 mustahce 확장자가 아닌 html으로 진행해서 그런 것이였음.

🚨3번

This application has no explicit mapping for /error, so you are seeing this as a fallback.

There was an unexpected error (type=Not Found, status=404).

No message available

→ 오타 발견해서 fix 완, 그런데 글등록 누르면 또 에러 뜸, 이것도 오타 문제인가?

🚨4번

문제 해결 → IndexController에 연결이 안되어있었음.

Bean이 없다는 것 = 패키지명 오류 (설정된 패키지가 없다는 것) → application properties 쪽으로 들어가니까 오타 있었음

🚨7번
IntelliJ finished with non-zero exit value 1 오류 수정

IntelliJ IDEA - preferences - Build,Execution,Deployment - Build Tools - Gradle - Build and run → build and run using을 Gradle default에서 IntelliJ IDEA로 변경하면 됨.

눈으로 확인하는 거 귀찮아서 아주 간단하게 코딩해서 알아봄

#include <iostream>
using namespace std;

int main()
{
    string str1;
    string str2;
    
    while(true){
        
        cout<<"1:"<<endl;
        cin>>str1;
        
        cout<<"2:"<<endl;
        cin>>str2;
        
        if(str1==str2){
            cout<<"ok"<<endl;
        }else{
            for(int i=0;i<str1.length();i++){
                if(str1[i]!=str2[i]){
                    cout<<str1[i]<<endl;
                    break;
                }
            }
        }
    }
}

구글 로그인만 설정했을 때는 되던 것이 네이버까지 설정하니까 안됨
