Spring Boot：無法確定數據庫類型 NONE 的嵌入式數據庫驅動程序類

Question

我有一個 SpringBoot 應用程序。 具有這些依賴項：

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

    <!-- https://mvnrepository.com/artifact/com.zaxxer/HikariCP -->
    <dependency>
        <groupId>com.zaxxer</groupId>
        <artifactId>HikariCP</artifactId>
    </dependency>

      <!-- Logging dependencies -->
    <dependency>
        <groupId>ch.qos.logback</groupId>
        <artifactId>logback-classic</artifactId>
    </dependency>    

    <!-- https://mvnrepository.com/artifact/com.github.noraui/ojdbc7 -->
    <dependency>
        <groupId>com.github.noraui</groupId>
        <artifactId>ojdbc7</artifactId>
        <version>12.1.0.2</version>
    </dependency> 

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

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-test</artifactId>
        <scope>test</scope>
    </dependency>
</dependencies>

但是當我運行應用程序時。 我收到此錯誤：

2017-10-23 15:09:01.095 ERROR 95375 --- [           main] o.s.test.context.TestContextManager      : Caught exception while allowing TestExecutionListener [org.springframework.boot.test.autoconfigure.SpringBootDependencyInjectionTestExecutionListener@15c43bd9] to prepare test instance [com.traxxeo.interfaces.TelefonicaInterfacesApplicationTests@72057ecf]

If you want an embedded database please put a supported one on the classpath. If you have database settings to be loaded from a particular profile you may need to active it (the profiles "prod" are currently active).

我不知道它來自哪里，因為我沒有任何訪問數據庫的類，而且我只有 1 個測試類：

@RunWith(SpringRunner.class)
@SpringBootTest
public class TelefonicaInterfacesApplicationTests {

    @Test
    public void contextLoads() {
    }

}

我收到了這個錯誤，因為我將數據庫依賴項放在 pom.xml 文件中，然后我才能毫無問題地運行它，並且它工作正常

Answer 1

我認為將以下代碼添加到 spring-config.xml 可能會解決該問題：

<bean id="dataSource"
        class="org.springframework.jdbc.datasource.DriverManagerDataSource">
        <property name="driverClassName" value="${DbDriverName}" />
        <property name="url" value="${DbUrl}" />
        <property name="username" value="${DbUsername}" />
        <property name="password" value="${DbPassword}" />
    </bean>

Answer 2

如果您的 Spring Boot 請求不處理任何數據庫連接，例如應用程序目的只是使用服務，則有一個名為 enable auto configuration 的注釋，您可以通過它提到要排除的瘦列表。

例如：@EnableAutoConfiguration(exclude = {DataSourceAutoConfiguration.class})
