添加依赖项后出现 UnsatisfiedDependencyException

Question

您好，我在路径中添加了依赖项和 ojdbc，但仍然收到 UnsatisfiesDependencyexception。

依赖关系

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-data-jpa</artifactId>
    </dependency>
        <dependency>
        <groupId> oracle </groupId>
        <artifactId>ojdbc6</artifactId>
        <version>11.2.0</version>
        <scope>system</scope>
        <systemPath>${project.basedir}/src/main/resources/ojdbc6.jar</systemPath>
    </dependency>

我把ojdbc6.jar放在src/main/resources中

界面ADAO

public interface ADao{
 A membershipFromxUsernameActive( String xUsername);
}

接口 ARepo

public interface ARepository extends Repository{

 @Query(value="SELECT m FROM A m where lower(m.x) = lower(:key) AND m.y='ACT'",nativeQuery=true)
    A fetchADetails(@Param("key") String key);

}

错误 即使我搜索了许多网站，也给出了解决方案，但我没有为我工作。

Answer 1

似乎在启动 spring boot 之前必须先启用数据源缓存，尝试在您的配置中添加这些属性
