Spring Boot：为什么我不能连接到两个不同的数据库？
[英]Spring Boot: Why can't I connect to two different databases?
问题描述
我正在使用此代码在线建模代码： https : //github.com/snicoll-demos/demo-multi-entity-managers
这是我的控制台输出：

这是我的应用程序文件：
@SpringBootApplication//(exclude = HibernateJpaAutoConfiguration.class)
//@EnableJpaRepositories(basePackageClasses = {LoadMethodRepository.class /*, TBL_GroupRepository.class*/})
//@EntityScan(basePackageClasses = {LoadMethodDO.class /*, TBL_GroupDO.class*/})
//@EnableCaching
public class Application {
private static final Logger log = LoggerFactory.getLogger(Application.class);
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
@Bean
public CommandLineRunner demo(LoadMethodRepository lm_repo /*, LMClientRepository lmc_repo */) {
return (args) -> {
System.out.println("*********Media ID**************");
System.out.println(lm_repo.findOne("4948460").getMediaId());
System.out.println("*********Media ID**************");
};
}
这是我的数据库之一的配置文件：
@Configuration
@EnableJpaRepositories(entityManagerFactoryRef = "lmEntityManagerFactory",
transactionManagerRef = "lmTransactionManager",
basePackageClasses = {EventsWithCommentsDO.class, LMClientDO.class, LoadMethodDO.class})
@EnableTransactionManagement
class LM_Config {
@Bean
@Primary
@ConfigurationProperties(prefix="spring.datasource")
public DataSource lmDataSource() {
return DataSourceBuilder.create().build();
}
@Bean
@Primary
LocalContainerEntityManagerFactoryBean lmEntityManagerFactory(final EntityManagerFactoryBuilder builder) {
return builder.dataSource(lmDataSource())
.packages("lmDataObjects")
.persistenceUnit("lmPersistenceUnit")
.build();
}
@Bean
@Primary
PlatformTransactionManager lmTransactionManager( @Qualifier("lmEntityManagerFactory") final EntityManagerFactory factory ) {
return new JpaTransactionManager(factory);
}
}
这是我用于其他数据库的配置文件：
@Configuration
@EnableJpaRepositories(entityManagerFactoryRef = "mtsEntityManagerFactory",
transactionManagerRef = "mtsTransactionManager",
basePackages = "database.mts.dataobjects")
public class MTS_Config {
@Bean
@ConfigurationProperties(prefix="spring.mtsDatasource")
public DataSource mtsDataSource() {
return DataSourceBuilder.create().build();
}
@Bean
LocalContainerEntityManagerFactoryBean mtsEntityManagerFactory(final EntityManagerFactoryBuilder builder) {
return builder.dataSource(mtsDataSource())
.packages("mtsDataObjects")
.persistenceUnit("mtsPersistentUnit")
.build();
}
@Bean
PlatformTransactionManager mtsTransactionManager( @Qualifier("mtsEntityManagerFactory") final EntityManagerFactory factory ) {
return new JpaTransactionManager(factory);
}
}
这是我的属性文件：
spring.jpa.generate-ddl=true
spring.jpa.hibernate.naming-strategy=org.hibernate.cfg.DefaultNamingStrategy
spring.datasource.username=xxxxdev
spring.datasource.password=xxxx
spring.datasource.url=jdbc:sqlserver://scherwqvsqlaod:1433;database=dbMOBClientTemp;integratedSecurity=false;
spring.datasource.testOnBorrow=true
spring.datasource.validationQuery=SELECT 1
spring.datasource.driverClassName=com.microsoft.sqlserver.jdbc.SQLServerDriver
#spring.jpa.database=dbMOBClientTemp
spring.jpa.show-sql=true
spring.jpa.hibernate.dialect=org.hibernate.dialect.SQLServer2012Dialect
spring.mtsDatasource.username=xxxx
spring.mtsDatasource.password=xxxx
spring.mtsDatasource.url=jdbc:sqlserver://SCHQVSQERLCON2:1433;database=dbMTS;integratedSecurity=false;
spring.mtsDatasource.testOnBorrow=true
spring.mtsDatasource.validationQuery=SELECT 1
spring.mtsDatasource.driverClassName=com.microsoft.sqlserver.jdbc.SQLServerDriver
hibernate.dialect=org.hibernate.dialect.SQLServer2012Dialect
hibernate.show_sql=true
hibernate.format_sql=true
hibernate.default_schema=dbo
hibernate.packagesToScan=src.repositories.LMClientRepository.java
我的数据对象文件只是POJO DO，我有实体，表，列和ID批注。 我的加载方法存储库文件如下所示
public interface LoadMethodRepository extends CrudRepository<LoadMethodDO, String>{
}
我的项目结构使我在最顶层具有application.java文件。 每个DO，回购和配置文件都在下面-类似于上面链接的项目。

我看到的问题是：
找不到类型为[database.loadmethod.repositories.LoadMethodRepository]的合格Bean
我认为您的应用程序的配置不匹配。 请尝试通过在Application.class中添加以下注释来配置Spring设置，以在哪里搜索存储库：
@ComponentScan(basePackageClasses = DataConfig.class)
您还需要创建相应的配置文件DataConfig ：
@Configuration
@EnableAutoConfiguration
@ComponentScan({"database.loadmethod.repositories"})
@Import({LM_Config.class, MTS_Config.class})
public class DataConfig {
}
希望这会有所帮助。
