Question

我试图使用Spring Boot 2.0.1来测试我的存储库层，但是当我运行测试类时，Spring尝试不从测试包中实例化Config类。

这是测试代码：

TestConfig.class

@Configuration
@Import(value = {TestDatabaseConfig.class})
@Profile("local")
public class TestConfig {

}

TestDatabaseConfig.class

@Configuration
@EnableTransactionManagement
@EnableJpaRepositories(
        entityManagerFactoryRef = "logEntityManagerFactory",
        transactionManagerRef = "logTransactionManager",
        basePackages = { "it.xxx.yyy.repository.log" })
@EntityScan(basePackages = {"it.xxx.yyy.model.log", "it.xxx.yyy.common"})
@Profile("local")
public class TestDatabaseConfig {

@Bean("logDataSourceProperties")
public DataSourceProperties logDataSourceProperties() {
    return new DataSourceProperties();
}


@Bean(name = "logDataSource")
public DataSource dataSource(@Qualifier("logDataSourceProperties") DataSourceProperties properties) {
    return new EmbeddedDatabaseBuilder()
            .setType(EmbeddedDatabaseType.H2)
            .addScript("classpath:schema.sql")
            .build();
}

@Bean(name = "logEntityManagerFactory")
public LocalContainerEntityManagerFactoryBean logEntityManagerFactory(EntityManagerFactoryBuilder builder,
                                                                      @Qualifier("logDataSource") DataSource logDataSource) {
    return builder.dataSource(logDataSource)
            .packages("it.xxx.model.log")
            .persistenceUnit("log")
            .build();
}

@Bean(name = "logTransactionManager")
public PlatformTransactionManager logTransactionManager(@Qualifier("logEntityManagerFactory")EntityManagerFactory logEntityManagerFactory) {
    return new JpaTransactionManager(logEntityManagerFactory);
}

}

运行此类时

@RunWith(SpringRunner.class)
@SpringBootTest
@ActiveProfiles("local")
public class LogRepositoryTest {

    @Autowired
    private ResultLogRepository resultLogRepository;

    @Test
    public void init(){
    }
}

它说：

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'kafkaProducer': Injection of autowired dependencies failed; nested exception is java.lang.IllegalArgumentException: Could not resolve placeholder 'kafka.topic.operation' in value "${kafka.topic.operation}"
[...]
Caused by: java.lang.IllegalArgumentException: Could not resolve placeholder 'kafka.topic.operation' in value "${kafka.topic.operation}"

但是我不明白为什么它会从我的主程序包（上面带有@Configuration注释）中调出我的KafkaProducer.class。

在您的LogRepositoryTest测试类中，您应该指出应该考虑的替代测试配置类，在您的情况下，我认为应该是TestConfig。

从Spring Boot documentation：

如果您熟悉Spring Test Framework，则可能习惯于使用@ContextConfiguration(classes=…)来指定要加载哪个Spring @Configuration。另外，您可能经常在测试中使用嵌套的@Configuration类。

因此用LogRepositoryTest注释@ContextConfiguration(classes = {TestConfig.class})

@RunWith(SpringRunner.class)
@SpringBootTest
@ActiveProfiles("local")
@ContextConfiguration(classes = {TestConfig.class})
public class LogRepositoryTest {

    @Autowired
    private ResultLogRepository resultLogRepository;

    @Test
    public void init(){
    }
}

更新

还使用以下注释您的配置类：

@EnableAutoConfiguration

类似：

@Configuration
@EnableAutoConfiguration
@EnableTransactionManagement
@EnableJpaRepositories(
        entityManagerFactoryRef = "logEntityManagerFactory",
        transactionManagerRef = "logTransactionManager",
        basePackages = { "it.xxx.yyy.repository.log" })
@EntityScan(basePackages = {"it.xxx.yyy.model.log", "it.xxx.yyy.common"})
@Profile("local")
public class TestDatabaseConfig {
//...
}

更新2

对于错误：

由以下原因引起：org.springframework.beans.factory.NoUniqueBeanDefinitionException：没有类型为'org.springframework.boot.autoconfigure.jdbc.DataSourceProperties'的合格Bean：预期为单个匹配的Bean，但发现2：logDataSourceProperties，spring.datasource- org.springframework.boot.autoconfigure.jdbc.DataSourceProperties

完全删除该方法：

@Bean("logDataSourceProperties")
public DataSourceProperties logDataSourceProperties() {
    return new DataSourceProperties();
}

并更改您的：

@Bean(name = "logDataSource")
public DataSource dataSource(@Qualifier("logDataSourceProperties") DataSourceProperties properties) {
 // ...
}

至：

@Bean(name = "logDataSource")
public DataSource dataSource(DataSourceProperties properties) {
 // ...
}
