데이터 소스의 스프링 부트 자동 구성

데이터 소스의 스프링 부트 자동 구성

Hibernate 5와 Postgres 9로 Spring Boot 앱을 만들려고 합니다.다음 오류가 발생하였습니다.

Parameter 0 of constructor in org.springframework.boot.autoconfigure.orm.jpa.HibernateJpaAutoConfiguration required a bean of type 'javax.sql.DataSource' that could not be found.
    - Bean method 'dataSource' not loaded because @ConditionalOnProperty (spring.datasource.jndi-name) did not find property 'jndi-name'
    - Bean method 'dataSource' not loaded because @ConditionalOnBean (types: org.springframework.boot.jta.XADataSourceWrapper; SearchStrategy: all) did not find any beans

단, spring.datasource를 추가하였습니다.* 속성:

spring.datasource.url=jdbc:postgresql://localhost:5432/postgres
spring.datasource.username=postgres
spring.datasource.password=root

좋은 생각 있어요?대부분의 튜토리얼에서는 이 모든 것이 매우 표준적이고 매우 심플합니다만, 조금 부족한 부분이 있는 것 같습니다.

클래스 경로에서 여러 클래스(대부분 풀 관련)가 누락되었습니다.가장 쉬운 해결책은 스프링 부트 스타터를 JPA에 사용하는 것입니다.이거는 다음과 같습니다.

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

이렇게 하면 다음과 같은 종속성이 모두 스타터의 일부이므로 제거할 수 있습니다.

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-context</artifactId>
    <version>${spring.version}</version>
</dependency>
<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-tx</artifactId>
    <version>${spring.version}</version>
</dependency>
<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-orm</artifactId>
    <version>${spring.version}</version>
</dependency>
<dependency>
    <groupId>org.springframework.data</groupId>
    <artifactId>spring-data-jpa</artifactId>
    <version>${spring.data.version}</version>
</dependency>

<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-core</artifactId>
    <version>${hibernate.version}</version>
</dependency>

대체 솔루션은 클래스 경로에 풀 공급자를 수동으로 추가하는 것입니다. spring-boot-starter-data-jpa의 기본값은 tomcat-jdbc(Spring boot 2.x의 경우 Hikari)이지만 설명서에 나와 있는 원하는 연결 풀 공급자를 사용할 수 있습니다.

위의 솔루션은 효과가 있을 수 있지만, 위의 Weblogic 11g 솔루션에서는 도움이 되지 않습니다.따라서 이 문제를 안고 있는 모든 사람이 이 솔루션을 사용할 수 있도록 이 솔루션을 첨부합니다.

솔루션:

컴포넌트 스캔 클래스 패스에 Data Source bean 구성을 추가하면 다음과 같은 weblogic 10.3.6(11g)과 같은 서블릿 2.5에서 이 설정이 수정됩니다.

@Configuration
public class DBConfig{

       @Bean
       public DataSource dataSource(){
          DriverManagerDataSource dataSource = new DriverManagerDataSource();
          dataSource.setDriverClassName("oracle.jdbc.driver.OracleDriver");
          dataSource.setUrl("your url");
          dataSource.setUsername( "username" );
          dataSource.setPassword( "password" );
          return dataSource;
       }

}
