如何在 SpringBoot 应用程序测试上下文中使用来自测试 application.yml 的 spring 数据源设置的参数实例化 groovy.sql.Sql？

Question

我有一个 SpringBoot maven 项目，它有一个存储库相关的 jar 子模块，它存储了与数据库相关的执行，存储库类和 JdbcTemplate 等

我想用 Spock 测试数据库 Groovy。

这是我的pom.xml:

...

这是来自 test/resources 的 application.yml:

spring: datasource: platform: sqlserver driver-class-name: com.microsoft.sqlserver.jdbc.SQLServerDriver url: jdbc:sqlserver://localhost;databaseName=mydatabase;integratedSecurity=true server: address: 127.0.0.1 port: 9000

这是 main/java/mypackage 中的 应用程序配置：

@Configuration @ComponentScan @EnableAutoConfiguration public class RepositoryConfig { }

这是 groovy 测试规范 应该设置 groovy.sql.Sql:

@SpringBootTest(classes = RepositoryConfig.class, webEnvironment = WebEnvironment.MOCK) @Configuration @EnableConfigurationProperties @Transactional class BaseSpringBootTestSpec extends Specification { String url String username String password String driverClassName protected groovy.sql.Sql sql def setup() { sql = groovy.sql.Sql.newInstance(url, username, password, driverClassName) } def cleanup() { sql.close() } }

但在这里我得到 NullPointerException，因为属性都是空的（url、driverClassName 等）。而且我不知道如何从文本上下文中的 yml 属性中获取它们。

有什么想法吗？谢谢。

您永远不会告诉 Spring 实际注入这些值。在您的字段中添加 @Value 注释应该可以解决您的问题。例如：

@Value("#{spring.datasource.url}")
String url
