我想在Spring Boot中使用两个数据库。代码如下：
第一个db config
@Configuration
@EnableAutoConfiguration
@EnableJpaRepositories(
basePackages = {"net.elyland.pipe.repositories.router"},
entityManagerFactoryRef = "routerEntityManagerFactory",
transactionManagerRef = "routerTransactionManager")
@EnableTransactionManagement
@PropertySource("classpath:application.properties")
@ComponentScan(basePackages = {"net.elyland.pipe.domain.router"})
public class RouterRepositoryConfiguration {
@Bean(name = "routerDataSource")
@ConfigurationProperties(prefix = "router.datasource")
public DataSource routerDataSource() {
return DataSourceBuilder
.create()
.build();
}
@PersistenceContext(unitName = "routerPU")
@Bean(name = "routerEntityManagerFactory")
public LocalContainerEntityManagerFactoryBean routerEntityManagerFactory(EntityManagerFactoryBuilder builder, @Qualifier("routerDataSource")DataSource routerDataSource) {
return builder
.dataSource(routerDataSource)
.properties(hibernateProperties())
.packages(Ip.class, Net.class, Provider.class, QueueRule.class, QueueType.class,RemoteIp.class,Subnet.class,TrafficQueue.class)
.persistenceUnit("routerPU")
.build();
}
@Bean(name = "routerTransactionManager")
public PlatformTransactionManager mysqlTransactionManager(@Qualifier("routerEntityManagerFactory") EntityManagerFactory entityManagerFactory) {
return new JpaTransactionManager(entityManagerFactory);
}
private Map hibernateProperties() {
Resource resource = new ClassPathResource("routerHibernate.properties");
try {
Properties properties = PropertiesLoaderUtils.loadProperties(resource);
return properties.entrySet().stream()
.collect(Collectors.toMap(
e -> e.getKey().toString(),
e -> e.getValue())
);
} catch (IOException e) {
return new HashMap();
}
}
}
第二个db config：
@Configuration
@EnableAutoConfiguration
@EnableJpaRepositories(
basePackageClasses = {SshUser.class, User.class, Role.class},
basePackages = {"net.elyland.pipe.domain.admin"},
entityManagerFactoryRef = "adminEntityManager" ,
transactionManagerRef = "adminTransactionManager"
)
@EnableTransactionManagement
@PropertySource({ "classpath:application.properties" })
public class AdminRepositoryConfiguration {
@Primary
@Bean(name = "adminDataSource")
@ConfigurationProperties(prefix = "admin.datasource")
public DataSource adminDataSource() {
System.out.println("Create datasource Admin");
return DataSourceBuilder
.create()
.build();
}
@Primary
@Bean(name = "adminEntityManager")
public LocalContainerEntityManagerFactoryBean adminEntityManager(EntityManagerFactoryBuilder builder, @Qualifier("adminDataSource") DataSource adminDataSource) {
return builder
.dataSource(adminDataSource)
.properties(hibernateProperties())
.packages(User.class, LocalIp.class, CommandLog.class, PipeSize.class, Role.class,Rule.class,Server.class,SshUser.class)
.persistenceUnit("adminPU")
.build();
}
@Primary
@Bean(name = "adminTransactionManager")
public PlatformTransactionManager adminTransactionManager(@Qualifier("adminEntityManager") EntityManagerFactory entityManagerFactory) {
return new JpaTransactionManager(entityManagerFactory);
}
private Map hibernateProperties() {
Resource resource = new ClassPathResource("hibernate.properties");
try {
Properties properties = PropertiesLoaderUtils.loadProperties(resource);
return properties.entrySet().stream()
.collect(Collectors.toMap(
e -> e.getKey().toString(),
e -> e.getValue())
);
} catch (IOException e) {
return new HashMap();
}
}
}
存储库1：
@Repository
@Transactional("adminTransactionManager")
public interface SshUserRepository extends JpaRepository<SshUser, Integer> {
SshUser findByUsername(String username);
}
存储库2：
@Repository
@Transactional("routerTransactionManager")
public interface SubnetRepository extends JpaRepository<Subnet, Integer> {
public Subnet findByAddress(Integer address);
public Subnet findByMask(Integer mask);
}
属性文件：
admin.datasource.url= jdbc:mysql://192.168.10.3:3306/pipe?autoReconnect=true&useSSL=false
admin.datasource.username=user
admin.datasource.password=pass
admin.datasource.driverClassName=com.mysql.jdbc.Driver
router.datasource.url= jdbc:mysql://192.168.10.3:3306/router?autoReconnect=true&useSSL=false
router.datasource.username=user
router.datasource.password=pass
router.datasource.driverClassName=com.mysql.jdbc.Driver
hibernate.properties：
#spring.jpa.show-sql = true
hibernate.dialect=org.hibernate.dialect.MySQL5Dialect
hibernate.hbm2ddl.auto=create-drop
一开始我有这个错误：
***************************
APPLICATION FAILED TO START

请在任一数据源配置中的bean上使用@Primary批注，它将起作用。
示例：
@Configuration
@EnableAutoConfiguration
@EnableJpaRepositories(
basePackages = {"net.elyland.pipe.repositories.router"},
entityManagerFactoryRef = "routerEntityManagerFactory",
transactionManagerRef = "routerTransactionManager")
@EnableTransactionManagement
@PropertySource("classpath:application.properties")
@ComponentScan(basePackages = {"net.elyland.pipe.domain.router"})
public class RouterRepositoryConfiguration {
@Primary
@Bean(name = "routerDataSource")
@ConfigurationProperties(prefix = "router.datasource")
public DataSource routerDataSource() {
return DataSourceBuilder
.create()
.build();
}
@Primary
@PersistenceContext(unitName = "routerPU")
@Bean(name = "routerEntityManagerFactory")
public LocalContainerEntityManagerFactoryBean routerEntityManagerFactory(EntityManagerFactoryBuilder builder, @Qualifier("routerDataSource")DataSource routerDataSource) {
return builder
.dataSource(routerDataSource)
.properties(hibernateProperties())
.packages(Ip.class, Net.class, Provider.class, QueueRule.class, QueueType.class,RemoteIp.class,Subnet.class,TrafficQueue.class)
.persistenceUnit("routerPU")
.build();
}
@Primary
@Bean(name = "routerTransactionManager")
public PlatformTransactionManager mysqlTransactionManager(@Qualifier("routerEntityManagerFactory") EntityManagerFactory entityManagerFactory) {
return new JpaTransactionManager(entityManagerFactory);
}
private Map hibernateProperties() {
Resource resource = new ClassPathResource("routerHibernate.properties");
try {
Properties properties = PropertiesLoaderUtils.loadProperties(resource);
return properties.entrySet().stream()
.collect(Collectors.toMap(
e -> e.getKey().toString(),
e -> e.getValue())
);
} catch (IOException e) {
return new HashMap();
}
}
}

在spring-boot中具有多个数据源时，请为每个数据源使用单独的类，以使代码易于阅读并避免此类错误（考虑在配置中定义一个名为'entityManagerFactory'的bean。）< / p>
如果应用程序中有单个数据源，则Spring Boot会为其创建一个默认的entityManagerFactory bean。但是，在拥有多个数据源时，我们需要为每个数据源显式定义entityManagerFactory和transactionManager。
例如，您必须在应用程序ds1和ds2中使用两个数据源，创建如下所示的bean：
ds1的Bean
@Configuration
@Import(SomePrimaryConfig.class)
@EnableJpaRepositories(
basePackages = "com.ds1.repos",
entityManagerFactoryRef = "ds1EMF",
transactionManagerRef = "ds1TM")
public class DataSource1 {
@Bean
@ConfigurationProperties("ds1.datasource")
public DataSource ds1DataSource() {
DataSourceBuilder<?> dataSourceBuilder = DataSourceBuilder.create();
// other datasource details to set
return dataSourceBuilder.build();
}
@Bean
LocalContainerEntityManagerFactoryBean ds1EMF(DataSource ds1DataSource) {
LocalContainerEntityManagerFactoryBean entityManagerFactoryBean = new LocalContainerEntityManagerFactoryBean();
entityManagerFactoryBean.setDataSource(ds1DataSource);
entityManagerFactoryBean.setPackagesToScan("com.ds1.models");
//entityManagerFactoryBean.setJpaProperties(jpaProperties);
return entityManagerFactoryBean;
}
@Bean
JpaTransactionManager ds1TM(EntityManagerFactory ds1EMF) {
JpaTransactionManager transactionManager = new JpaTransactionManager();
transactionManager.setEntityManagerFactory(ds1EMF);
return transactionManager;
}
}
ds2的Bean
@Configuration
@Import(SomePrimaryConfig.class)
@EnableJpaRepositories(
basePackages = "com.ds2.repos",
entityManagerFactoryRef = "ds2EMF",
transactionManagerRef = "ds2TM")
public class DataSource2 {
@Bean
@ConfigurationProperties("ds2.datasource")
public DataSource ds1DataSource() {
DataSourceBuilder<?> dataSourceBuilder = DataSourceBuilder.create();
// other datasource details to set
return dataSourceBuilder.build();
}
@Bean
LocalContainerEntityManagerFactoryBean ds2EMF(DataSource ds2DataSource) {
LocalContainerEntityManagerFactoryBean entityManagerFactoryBean = new LocalContainerEntityManagerFactoryBean();
entityManagerFactoryBean.setDataSource(ds2DataSource);
entityManagerFactoryBean.setPackagesToScan("com.ds2.models");
//entityManagerFactoryBean.setJpaProperties(jpaProperties);
return entityManagerFactoryBean;
}
@Bean
JpaTransactionManager ds2TM(EntityManagerFactory ds2EMF) {
JpaTransactionManager transactionManager = new JpaTransactionManager();
transactionManager.setEntityManagerFactory(ds2EMF);
return transactionManager;
}
}
