Question

我有一个基本的SpringBoot 2.1.5.RELEASE应用程序。使用Spring Initializer，JPA，嵌入式Tomcat，Thymeleaf模板引擎并将其打包为可执行JAR文件。我正在为开发人员使用内存数据库，也为测试使用了mySQL

   <dependency>
            <groupId>com.h2database</groupId>
            <artifactId>h2</artifactId>
        </dependency>

        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
            <scope>runtime</scope>
        </dependency>

但是当我在测试（MySQL）上运行测试时，最后出现此错误：

由于我使用的是Spring配置文件，因此我对每个配置使用不同的属性：

@Configuration
@Profile("dev")
@EnableJpaRepositories(basePackages = "com.calzada.backend.persistence.repositories")
@EntityScan(basePackages = "com.calzada.backend.persistence.domain.backend")
@EnableTransactionManagement
@EnableCaching
@PropertySource("file:///${user.home}/bonanza/application-dev.properties")
@PropertySource("file:///${user.home}/bonanza/application-common.properties")
public class DevelopmentConfig {


    @Bean
    public ServletRegistrationBean<WebServlet> h2ConsoleServletRegistration() {
        ServletRegistrationBean<WebServlet> bean = new ServletRegistrationBean<WebServlet>(new WebServlet());
        bean.addUrlMappings("/console/*");
        return bean;
    }

}

这是我的pom.xml文件：

Answer 1

您应该查看application.property，必须有两个application.property。一个用于测试配置，一个用于测试。确保手动创建两个数据源，一个用于使用h2的数据源，一个用于mysql。

创建名称为“ inMemoryDatabaseShutdownExecutor”的bean时出错：
