【中文标题】NoSuchBeanDefinitionException：PlatformTransactionManager 在 Spring Boot 2.0.0.M6 中运行 Junit 测试

【英文标题】：NoSuchBeanDefinitionException: PlatformTransactionManager running Junit Tests in Spring Boot 2.0.0.M6

【问题描述】：

我使用 Spring Initializer、嵌入式 Tomcat、Thymeleaf 模板引擎生成了一个 Spring Boot Web 应用程序，并将其打包为可执行 JAR 文件。 当我在正常模式下运行应用程序时，它似乎工作正常

使用的技术：

Spring Boot 2.0.0.M6，Java 8，maven，我没有使用 JPA，jdbcTemplate

我有这个 JUnit 测试：

@SpringBootTest
@ContextConfiguration(classes=PersistenceConfig.class)
@RunWith(SpringRunner.class)
public class JdbcMetricsRepositoryTests 

    @Autowired
    MetricsRepository jdbcMetricsRepository;

    @Test
    public void testGetAllDeviceEventsWithAlarm() throws DataAccessException, SQLException 

        //jdbcMetricsRepository.getIberiaDataTab1();

        assertNotNull (jdbcMetricsRepository.getIberiaDataTab1());
    

但是当我运行测试时，我得到了这个错误：

【问题讨论】：

PersistenceConfig 看起来像...？

你需要有一个@Bean 方法来返回一个PlatformTransactionManager 的实例。以baeldung.com/transaction-configuration-with-jpa-and-spring为例

但我没有使用 JPA

所以你没有在你的测试中使用自动配置，并且仍然期望 spring boot 自动配置一切。你为什么这么努力不使用 Spring Boot？

【参考方案1】：

由于您重新定义了数据源，您可以通过定义下面的 bean 来定义您的 PlatformTransactionManger

@Bean
public DataSourceTransactionManager transactionManager() 
    final DataSourceTransactionManager txManager = new DataSourceTransactionManager();
    txManager.setDataSource(dataSource);

    return txManager;

【讨论】：

但我没有使用 JPA

对于那些需要 DataSouce 但不介意使用 h2（嵌入式内存数据库）的人：JdbcDataSource dataSource = new JdbcDataSource(); dataSource.setURL("jdbc:h2:mem:test"); txManager.setDataSource(dataSource); 并添加到您的 pom.xml：<dependency> <groupId>com.h2database</groupId> <artifactId>h2</artifactId> <version>1.4.199</version> <scope>test</scope> </dependency>
