[Spring-Boot] 실행시 dataSource 해결방법

Spring boot 실행시 아래와 같은 에러가 나왔다.

2020-12-08 23:12:31.312 ERROR 256300 --- [ main] o.s.b.d.LoggingFailureAnalysisReporter :

***************************
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 (no profiles are currently active).

 

 

반응형

 

 

아래와 같이 jdbc dependency를 추가한 상태에서 dataSource를 설정해주지 않아서 발생한 것이었음.

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-jdbc</artifactId>
</dependency>

 

db구축이 되어있지 않다면 위 dependency를 제거하고,

db구축이 되어있다면 아래와 같이 application.properties에 DB 설정 정보를 추가하면 해결된다.

spring.datasource.driver-class-name=oracle.jdbc.OracleDriver spring.datasource.url=jdbc:oracle:thin:@localhost:1521/xe spring.datasource.username=admin spring.datasource.password=1234
