springboot的demo，测试的时候报datasource的url错误，求帮忙！！
新建的springboot项目，测试的时候始终报datasource的url不正确，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
找过好多方法都不行，实在搞不明白哪里有问题，求各位帮忙看看！
这是pom.xml
程序代码：<properties>
<java.version>1.8</java.version>
<thymeleaf.version>3.0.11.RELEASE</thymeleaf.version>
<thymeleaf-layout-dialect.version>2.3.0</thymeleaf-layout-dialect.version>
<maven-jar-plugin.version>3.1.1</maven-jar-plugin.version>
</properties>

</dependency>
<!-- 测试工具启动器 -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
</dependency>
</dependencies>这是applicationContext.properties
程序代码：spring.datasource.driver-class-name = com.mysql.cj.jdbc.Driver spring.datasource.url = jdbc:mysql://localhost:3306/jpa_study?characterEncoding=utf-8&useSSL=false&serverTimezone=UTC spring.datasource.username = root spring.datasource.password = 123456 spring.datasource.type = com.alibaba.druid.pool.DruidDataSource spring.jpa.hibernate.ddl-auto = update spring.jpa.show-sql =true
mysql-connector-java-8.0.18.jar
这是respository
public interface UsersRepository extends JpaRepository<Users, Integer> {
}这是JUnit测试
程序代码：@RunWith(SpringJUnit4ClassRunner.class)
@SpringBootTest(classes=App.class)
public class UsersRepositoryTest {
@Autowired
private UsersRepository usersRepository;
@Test
public void testSave(){
Users users = new Users("张三", 22, "北京武汉");
this.usersRepository.save(users);
}
}然后启动测试，始终报这个错
程序代码：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).
