Spring Data自动装配多个数据源失败
[英]Spring Data autowiring multiple datasources fails
问题描述
I have been hacking away at trying to get multiple mysql datasources into a Spring jpa application for what seems like forever. 
我一直在努力尝试将多个mysql数据源永久地添加到Spring jpa应用程序中。 I have yet to find a good, working example online. 我尚未在网上找到一个很好的工作示例。 Below are excerpts from an extremely stripped down app I'm making just to see if it is even possible in a vacuum to be able to autowire and query repositories for more than one MySQL db. 下面是我正在精简的一个应用程序的摘录，我只是想看看是否有可能在多个数据库中自动装配和查询存储库。 No matter what annotations I sub in or out nothing changes, I always get the same error: 无论我加入或退出什么注释都没有变化，我总是会遇到相同的错误：
Error creating bean with name 'application': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: com.download.integration.repository.primary.PrimaryRepository com.download.Application.PrimaryRepository; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [com.download.integration.repository.primary.PrimaryRepository] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}
Here is my setup. 这是我的设置。 Primary and Secondary beans and repos are in their own packages per the advice of several previously answered items. 根据几个先前回答的项目的建议，主要和次要bean和回购协议在各自的包装中。
first config: 第一个配置：
@Configuration
@EnableTransactionManagement
@EnableJpaRepositories(
entityManagerFactoryRef = "primaryEntityManagerFactory",
transactionManagerRef = "primaryTransactionManager",
basePackages = { "com.download.integration.repositories.primary" })
public class PrimaryConfig{
@Bean
public JpaVendorAdapter jpaVendorAdapter() {
HibernateJpaVendorAdapter adaptor = new HibernateJpaVendorAdapter();
adaptor.setShowSql(false);
adaptor.setGenerateDdl(false);
adaptor.setDatabase(Database.MYSQL);
return adaptor;
}
@Primary
@Bean(name = "primaryDataSource")
public DataSource primaryDataSource() {
BasicDataSource ds = new BasicDataSource();
ds.setDriverClassName("com.mysql.jdbc.Driver");
ds.setUrl("jdbc:mysql://127.0.0.1:3306/primarydb");
ds.setUsername("user");
ds.setPassword("password");
return ds;
}
@Bean(name = "primaryEntityManager")
public EntityManager primaryEntityManager() {
return primaryEntityManagerFactory().createEntityManager();
}
@Bean(name = "primaryEntityManagerFactory")
public EntityManagerFactory primaryEntityManagerFactory() {
LocalContainerEntityManagerFactoryBean lef = new LocalContainerEntityManagerFactoryBean();
lef.setDataSource(primaryDataSource());
lef.setJpaVendorAdapter(jpaVendorAdapter());
lef.setPackagesToScan("com.download.domain.primary");
lef.setPersistenceUnitName("primaryPersistenceUnit");
lef.afterPropertiesSet();
return lef.getObject();
}
@Bean(name = "primaryTransactionManager")
public PlatformTransactionManager primaryTransactionManager() {
return new JpaTransactionManager(primaryEntityManagerFactory());
}
}
secondary config: 辅助配置：
@Configuration
@EnableTransactionManagement
@EnableJpaRepositories(
entityManagerFactoryRef = "secondaryEntityManagerFactory",
transactionManagerRef = "secondaryTransactionManager",
basePackages = { "com.download.integration.repositories.secondary" })
public class SecondaryConfig{
@Bean
public JpaVendorAdapter jpaVendorAdapter() {
HibernateJpaVendorAdapter adaptor = new HibernateJpaVendorAdapter();
adaptor.setShowSql(false);
adaptor.setGenerateDdl(false);
adaptor.setDatabase(Database.MYSQL);
return adaptor;
}
@Bean(name = "secondaryDataSource")
public DataSource secondaryDataSource() {
BasicDataSource ds = new BasicDataSource();
ds.setDriverClassName("com.mysql.jdbc.Driver");
ds.setUrl("jdbc:mysql://127.0.0.1:3306/secondarydb");
ds.setUsername("user");
ds.setPassword("password");
return ds;
}
@Bean(name = "secondaryEntityManager")
public EntityManager secondaryEntityManager() {
return secondaryEntityManagerFactory().createEntityManager();
}
@Bean(name = "secondaryEntityManagerFactory")
public EntityManagerFactory secondaryEntityManagerFactory() {
LocalContainerEntityManagerFactoryBean lef = new LocalContainerEntityManagerFactoryBean();
lef.setDataSource(secondaryDataSource());
lef.setJpaVendorAdapter(jpaVendorAdapter());
lef.setPackagesToScan("com.download.domain.secondary");
lef.setPersistenceUnitName("secondaryPersistenceUnit");
lef.afterPropertiesSet();
return lef.getObject();
}
@Bean(name = "secondaryTransactionManager")
public PlatformTransactionManager secondaryTransactionManager() {
return new JpaTransactionManager(secondaryEntityManagerFactory());
}
}
primary datasource model: 主要数据源模型：
@Entity
public class Primary {
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private Integer id;
private String word;
private Double weight;
private Date updated;
private String sources;
...constructors, getters, setters ...构造函数，getters，setters
secondary datasource model: 辅助数据源模型：
@Entity
public class Secondary {
@Id
private String uuid;
private String name;
private Double weight;
...constructors, getters, setters ...构造函数，getters，setters
And repositories (I have experiments with adding @Repository and seen no change) 和存储库（我进行了添加@Repository的实验，发现没有变化）
public interface PrimaryRepository extends CrudRepository<Primary, Integer> {
}
public interface SecondaryRepository extends CrudRepository<Secondary, Integer> {
}
finally, the main class: 最后，主要课程：
@ComponentScan("com.download")
@EnableAutoConfiguration(exclude = { DataSourceTransactionManagerAutoConfiguration.class, DataSourceAutoConfiguration.class, HibernateJpaAutoConfiguration.class })
@Import({PrimaryConfig.class, SecondaryConfig.class})
public class Application implements CommandLineRunner{
@Autowired
PrimaryRepository primaryrepository;
@Autowired
SecondaryRepository secondaryrepository;
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
@Override
public void run(String... args) throws Exception {
search();
}
public void search(){
primaryrepository.findAll();
secondaryrepository.findAll();
}
}
Adding full stack trace per request: 为每个请求添加完整的堆栈跟踪：

You can remove @Import and put @EnableAutoConfiguration without exclude field for simplicity. 您可以删除@Import并把@EnableAutoConfiguration不exclude现场的简单性。 Also, try adding @Configuration to your main class. 另外，尝试将@Configuration添加到您的主类。
EDIT: 编辑：
I've created a project with your classes and made if work after following changes: 我用您的课程创建了一个项目，并在进行以下更改后使其工作：

primaryrepository.findAll();
secondaryrepository.findAll();

My code exhibited the same issue, where it was ignoring secondary databases in a multiple database configuration and aways using the one annotated as primary. 我的代码也遇到了同样的问题，即它忽略了多数据库配置中的辅助数据库，而没有使用注释为主要数据库的辅助数据库。 Found the problem cause by having @EnableJpaRepositories in one of controllers. 通过在一个控制器中具有@EnableJpaRepositories发现了问题原因。 After I removed the annotation, everything started working as expected. 删除注释后，一切都按预期开始工作。
