Question

在Java项目中，我使用的是Sprig Boot 1.5.3.RELEASE。它连接两个数据库，即 MongoDB和Microsoft SQLServer 。当我使用 spring-boot：run 目标运行它时，它运行正常。但是，当我尝试使用 package 目标运行它时，测试用例会报告以下错误，尽管这些测试用例未连接到SQL Server数据库：

Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'org.springframework.boot.orm.jpa.EntityManagerFactoryBuilder' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {}

MediationTest.java（包含生成错误的测试用例的Java类）

@RunWith(SpringRunner.class)
@DataMongoTest(excludeAutoConfiguration = EmbeddedMongoAutoConfiguration.class)
@SpringBootTest(classes = { Application.class })
public class MediationTest {

    @Autowired
    private SwiftFormat swiftFormat;

MsqlDbConfig.java

@Configuration
@EnableTransactionManagement
@EnableJpaRepositories(entityManagerFactoryRef = "msqlEntityManagerFactory", transactionManagerRef = "msqlTransactionManager", basePackages = { "com.msql.data" })
public class MsqlDbConfig {

    @Bean(name = "msqlDataSource")
    @ConfigurationProperties(prefix = "msql.datasource")
    public DataSource dataSource() {
        return DataSourceBuilder.create().build();
    }

    @Bean(name = "msqlEntityManagerFactory")
    public LocalContainerEntityManagerFactoryBean msqlEntityManagerFactory(
            EntityManagerFactoryBuilder builder,
            @Qualifier("msqlDataSource") DataSource dataSource) {
        return builder.dataSource(dataSource)
                .packages("com.utils.msql.info")
                .persistenceUnit("msql").build();
    }

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

spring-boot：run 目标由spring-boot-maven-plugin项目中包含的Mojo定义。你可以在这里找到它。 https://github.com/spring-projects/spring-boot/blob/8e3baf3130220a331d540cb07e1aca263b721b38/spring-boot-tools/spring-boot-maven-plugin/src/main/java/org/springframework/boot/maven/RunMojo.java

Form2.Onclose范围设置为“测试”。这将包括类路径上每个阶段的依赖关系。看看这里的规范。 https://maven.apache.org/developers/mojo-api-specification.html

Maven提供的包目标不会在类路径中包含这些额外的依赖项，我相信这是导致问题的原因。

Spring Boot提供了一个 repackage 目标，该目标应该用于构建可执行的spring-boot应用程序。

然而，要获得更多关键点。我认为，如果您更新测试以排除其他类，则可能会解决您的问题。

requiresDependencyResolution

没有'org.springframework.boot.orm.jpa.EntityManagerFactoryBuilder'类型的限定bean
