Question

我有一个Spring Boot应用程序，并且在应用程序和之前的JUNIT测试中运行良好。

我最近开始使用JDBCTemplate和DataSource，所有测试都无法启动。

stacktrace的主要问题是，一旦尝试自动装配数据源或jdbc模板，它似乎无法找到数据源属性

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'directoryLoader': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: org.springframework.jdbc.core.JdbcTemplate com.millerhare.winfsapi.fsloader.DirectoryLoader.jdbcTemplate; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration$JdbcTemplateConfiguration': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private javax.sql.DataSource org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration$JdbcTemplateConfiguration.dataSource; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'dataSource' defined in class path resource [org/springframework/boot/autoconfigure/jdbc/DataSourceAutoConfiguration$NonEmbeddedConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [javax.sql.DataSource]: Factory method 'dataSource' threw exception; nested exception is org.springframework.boot.autoconfigure.jdbc.DataSourceProperties$DataSourceBeanCreationException: Cannot determine embedded database driver class for database type NONE. 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 (no profiles are currently active).

这是Autowire类

@Component
public class DirectoryLoader {


@Autowired
JdbcTemplate jdbcTemplate;

@Autowired
DataSource ds;

但是在应用程序和测试的application.properties中，所有数据源属性都已设置

spring.datasource.url=jdbc\:oracle\:thin\:@xxxx
spring.datasource.username=xxxx
spring.datasource.driver-class-name=oracle.jdbc.OracleDriver

我已经尝试更改其他属性，例如server.port，这些属性已被选中，因此很明显找到了application.properties文件。

我测试的原始配置是

 @RunWith(SpringJUnit4ClassRunner.class)
 @SpringApplicationConfiguration(classes = WinFsapiApplication.class)
 @WebIntegrationTest

我也尝试通过@TestPropertiesSource设置属性，但这也找不到它们。我错过了什么？

Answer 1

为什么数据源URL中有反斜杠？字符串应为spring.datasource.url=jdbc:oracle:thin:@xxxxx。我相信你有一个\的事实导致驱动程序的自动检测（指定URL应该足以检测驱动程序类，你不需要指定它）。

Answer 2

我遇到了类似的问题，春季启动应用程序运行良好，我可以从Postman测试它，但Junits失败了。将application.properties添加到src / test / resources为我解决了它。我知道spring boot应该从src / main / resources中获取它，但即使我要求它在我的配置文件中使用@PropertySource（“classpath：application.properties”）专门查找它也不行。
