Spring-Data-MongoDB 연동

1. MongoDB 사용자 권한 설정하기

 

첫번재 cmd 창 - mongod 접속

 

 

두 번째 cmd창 띄운 후 - mongo 접속

 

 

두 번째 cmd 창에 계정 만들기

# 참고 : 밑에 소스코드 예제는 user : "admin" , pwd : "admin" , db: test 이다 

 

 

 

2. spring project 만들기

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

3. MongoDB에 데이터 들어갔는지 확인하기

 

- cmd 창 권한 변경하기

첫번째 cmd창 나갔다가(ctrl + c) -> mongod.exe -auth 입력

- 두번째 cmd창 나갔다가 -> mongo 입력

- use admin   // admin 계정 사용하기

  db.auth("userName","pwd");  // userName: 사용자 , pwd: 비밀번호 

  use test // test : DB 이름

  db.person.find(); // person : collection

소스코드
