프로젝트 빌드 중 Tomcat 오류 'Failed to configure a DataSource: 'url' attribute is not specified and no embedded datasource could be configured. '

❌ error!!

  • 상황 : jenkins로 프로젝트 구성 후, 첫 빌드를 시작.
    - Tomcat까지 실행에 성공하였다. 그러나 그 후 Deplying 과정에서 에러가 자꾸 났다.
  • 에러메시지
Tomcat started.

Build step 'Deploy war/ear to a container' marked build as failure
Finished: FAILURE
  • 서치 해 본 결과, 해당 단계에서 tomcat 비밀번호를 틀렸다든가 하는 사례들이 몇몇 있었다. 하지만 나의 경우에는 다른 것들은 다 틀림이 없이 구성을 해놓았었다.

파악

  1. Tomcat log 파일을 뒤져보았다.
# log 파일 경로로 이동
cd /usr/local/tomcat9/logs

# 파일 열기 (이름이 다를 수 있으므로 ls로 확인하고 열자)
vi catalina.out
  1. 문제 상황 확인
***************************
APPLICATION FAILED TO START
***************************

Description:

Failed to configure a DataSource: 'url' attribute is not specified and no embedded datasource could be configured.

Reason: Failed to determine a suitable driver class


Action:

Consider the following:
        If you want an embedded database (H2, HSQL or Derby), please put it on the classpath.
        If you have database settings to be loaded from a particular profile you may need to activate it (the profiles aws are currently active).
       
        ...
        (후략)
        ...
  • 위와 같은 메시지가 기록되어있다. DB와 연결이 안되었다는 뜻이며, url부터 지정해주어야 한다.
  1. 원인 보안탓에 DB 정보를 github에 올라가지 않게 막아두고, 별도의 properties에 옮겨놓았는데.. 깜빡 잊고 서버에 추가를 안했었다🥹 이게 원인이었다니 허무하다..!

해결

  1. 프로젝트 경로로 이동
# 현재 위치 파악
pwd

# 프로젝트 경로로 이동
# 위의 오류 메시지에 기록되어 있음.
cd /opc/var/lib/jenkins/workspace
  1. properties 파일 위치로 이동

  2. application.properties 파일 생성

sudo vi aplication-oci.properties

# DB 정보 입력 (mySql)
spring.datasource.url=jdbc:mysql://127.0.0.1:3306/{스키마}?autoReconnect=true spring.datasource.username={DB ID}
spring.datasource.password={DB Pw}
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
