我正在使用Spring Boot 2，Spring Data REST，Spring HATEOAS，Spring JPA，Hibernate。 在上次更改之前，我的项目运行良好，在该处添加了新的EntityManager。
这是开始课程：
@SpringBootApplication(exclude = {DataSourceAutoConfiguration.class, DataSourceTransactionManagerAutoConfiguration.class,
HibernateJpaAutoConfiguration.class})
@EnableAsync
@ComponentScan(basePackages = {"cloud.myapp", "management"})
public class OptixServerApplication {
public static void main(String[] args) {
SpringApplication.run(ServerApplication.class, args);
}
}
这是第一个entityManager：
@Configuration
@Profile("prod")
@EnableJpaRepositories(
basePackages = "cloud.myapp.server.repositories",
entityManagerFactoryRef = "entityManagerFactory",
transactionManagerRef = "transactionManager"
)
public class HibernateConfig {
@Autowired
private Environment env;
@Autowired
private LocalValidatorFactoryBean validator;
@Primary
@Bean(name = "entityManagerFactory")
public LocalContainerEntityManagerFactoryBean entityManagerFactory(MultiTenantConnectionProvider multiTenantConnectionProviderImpl,
CurrentTenantIdentifierResolver currentTenantIdentifierResolverImpl) throws InstantiationException, IllegalAccessException,
ClassNotFoundException, IllegalArgumentException, InvocationTargetException, NoSuchMethodException, SecurityException {
Map<String, Object> properties = new HashMap<>();
properties.put(org.hibernate.cfg.Environment.MULTI_TENANT, MultiTenancyStrategy.DATABASE);
properties.put(org.hibernate.cfg.Environment.MULTI_TENANT_CONNECTION_PROVIDER, multiTenantConnectionProviderImpl);
properties.put(org.hibernate.cfg.Environment.MULTI_TENANT_IDENTIFIER_RESOLVER, currentTenantIdentifierResolverImpl);
LocalContainerEntityManagerFactoryBean em = new LocalContainerEntityManagerFactoryBean();
em.setPersistenceUnitName("myapp.U");
em.setDataSource(dataSource());
em.setPackagesToScan("cloud.myapp.server");
em.setJpaPropertyMap(properties);
HibernateJpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
em.setJpaVendorAdapter(vendorAdapter);
properties = new HashMap<>();
properties.put("hibernate.hbm2ddl.auto", env.getProperty("hibernate.hbm2ddl.auto"));
properties.put("hibernate.generate_statistics", env.getProperty("hibernate.generate_statistics"));
properties.put("hibernate.dialect", env.getProperty("hibernate.dialect"));
properties.put("hibernate.dialect.storage_engine", env.getProperty("hibernate.dialect.storage_engine"));
properties.put("hibernate.show_sql", env.getProperty("hibernate.show_sql"));
properties.put("hibernate.implicit_naming_strategy", env.getProperty("hibernate.implicit_naming_strategy"));
properties.put("hibernate.jdbc.fetch_size", env.getProperty("hibernate.jdbc.fetch_size"));
properties.put("hibernate.jdbc.batch_size", env.getProperty("hibernate.jdbc.batch_size"));
properties.put("hibernate.max_fetch_depth", env.getProperty("hibernate.max_fetch_depth"));
properties.put("hibernate.cache.use_second_level_cache", env.getProperty("hibernate.cache.use_second_level_cache"));
properties.put("hibernate.jdbc.time_zone", env.getProperty("hibernate.jdbc.time_zone"));
properties.put("hibernate.globally_quoted_identifiers", env.getProperty("hibernate.globally_quoted_identifiers"));
properties.put("hibernate.globally_quoted_identifiers_skip_column_definitions",
env.getProperty("hibernate.globally_quoted_identifiers_skip_column_definitions"));
// Interceptor for Agents
// properties.put("hibernate.session_factory.interceptor", agentInterceptor());
// properties.put("hibernate.session_factory.interceptor", hibernateInterceptor());
em.setJpaPropertyMap(properties);
em.afterPropertiesSet();
return em;
}
@Primary
@Bean
public DataSource dataSource() throws InstantiationException, IllegalAccessException, ClassNotFoundException, IllegalArgumentException,
InvocationTargetException, NoSuchMethodException, SecurityException {
final SimpleDriverDataSource dataSource = new SimpleDriverDataSource();
dataSource.setDriver(((Driver) Class.forName(env.getProperty("primary.datasource.driver-class-name")).getDeclaredConstructor()
.newInstance(null)));
dataSource.setUrl(env.getProperty("primary.datasource.url"));
dataSource.setUsername(env.getProperty("primary.datasource.username"));
dataSource.setPassword(env.getProperty("primary.datasource.password"));
return dataSource;
}
@Primary
@Bean
public PlatformTransactionManager transactionManager(MultiTenantConnectionProvider multiTenantConnectionProviderImpl,
CurrentTenantIdentifierResolver currentTenantIdentifierResolverImpl) throws InstantiationException, IllegalAccessException,
ClassNotFoundException, IllegalArgumentException, InvocationTargetException, NoSuchMethodException, SecurityException {
JpaTransactionManager transactionManager = new JpaTransactionManager();
transactionManager.setEntityManagerFactory(
entityManagerFactory(multiTenantConnectionProviderImpl, currentTenantIdentifierResolverImpl).getObject());
return transactionManager;
}
}
这是另外一个：
@Configuration
@PropertySource({"classpath:management.properties"})
@EnableJpaRepositories(
basePackages = "cloud.management.server.repositories",
entityManagerFactoryRef = "managementEntityManager",
transactionManagerRef = "managementTransactionManager"
)
@Log4j2
public class ManagementDBConfig {
@Autowired
private Environment env;
@Bean(name = "managementEntityManager")
public LocalContainerEntityManagerFactoryBean managementEntityManager() {
LocalContainerEntityManagerFactoryBean em = new LocalContainerEntityManagerFactoryBean();
em.setDataSource(managementDataSource());
em.setPackagesToScan("cloud.management.server.model");
HibernateJpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
em.setJpaVendorAdapter(vendorAdapter);
HashMap<String, Object> properties = new HashMap<>();
properties.put("hibernate.hbm2ddl.auto", env.getProperty("management.jpa.hibernate.ddl-auto"));
properties.put("hibernate.dialect", env.getProperty("management.jpa.properties.hibernate.dialect"));
properties.put("hibernate.show_sql", env.getProperty("management.jpa.hibernate.show_sql"));
properties.put("hibernate.jdbc.fetch_size", env.getProperty("management.jpa.hibernate.jdbc.fetch_size"));
properties.put("hibernate.jdbc.batch_size", env.getProperty("management.jpa.hibernate.jdbc.batch_size"));
properties.put("hibernate.max_fetch_depth", env.getProperty("management.jpa.hibernate.max_fetch_depth"));
properties.put("hibernate.cache.use_second_level_cache", env.getProperty("management.jpa.hibernate.cache.use_second_level_cache"));
properties.put("hibernate.jdbc.time_zone", env.getProperty("management.jpa.hibernate.jdbc.time_zone"));
properties.put("hibernate.globally_quoted_identifiers", env.getProperty("management.jpa.hibernate.globally_quoted_identifiers"));
properties.put("hibernate.globally_quoted_identifiers_skip_column_definitions", env.getProperty("management.jpa.hibernate.globally_quoted_identifiers_skip_column_definitions"));
em.setJpaPropertyMap(properties);
return em;
}
@Bean
public DataSource managementDataSource() {
return createDataSource();
}
@Bean
public PlatformTransactionManager managementTransactionManager() {
JpaTransactionManager transactionManager = new JpaTransactionManager();
transactionManager.setEntityManagerFactory(managementEntityManager().getObject());
return transactionManager;
}
private DataSource createDataSource() {
HikariConfig hikari = new HikariConfig();
hikari.setJdbcUrl(env.getProperty("management.datasource.url"));
hikari.setUsername(env.getProperty("management.datasource.username"));
hikari.setPassword(env.getProperty("management.datasource.password"));
// MySQL optimizations, see
// https://github.com/brettwooldridge/HikariCP/wiki/MySQL-Configuration
String keyPrefix = "management.hikari.";
hikari.addDataSourceProperty("cachePrepStmts", env.getProperty(keyPrefix + "cachePrepStmts"));
hikari.addDataSourceProperty("prepStmtCacheSize", env.getProperty(keyPrefix + "prepStmtCacheSize"));
hikari.addDataSourceProperty("prepStmtCacheSqlLimit", env.getProperty(keyPrefix + "prepStmtCacheSqlLimit"));
hikari.addDataSourceProperty("useServerPrepStmts", env.getProperty(keyPrefix + "useServerPrepStmts"));
hikari.addDataSourceProperty("useLocalSessionState", env.getProperty(keyPrefix + "useLocalSessionState"));
hikari.addDataSourceProperty("rewriteBatchedStatements", env.getProperty(keyPrefix + "rewriteBatchedStatements"));
hikari.addDataSourceProperty("cacheResultSetMetadata", env.getProperty(keyPrefix + "cacheResultSetMetadata"));
hikari.addDataSourceProperty("cacheServerConfiguration", env.getProperty(keyPrefix + "cacheServerConfiguration"));
hikari.addDataSourceProperty("elideSetAutoCommits", env.getProperty(keyPrefix + "elideSetAutoCommits"));
hikari.addDataSourceProperty("maintainTimeStats", env.getProperty(keyPrefix + "maintainTimeStats"));
hikari.setMinimumIdle(Integer.valueOf(env.getProperty(keyPrefix + "minimumIdle")));
hikari.setMaximumPoolSize(Integer.valueOf(env.getProperty(keyPrefix + "maximumPoolSize")));
hikari.setIdleTimeout(Long.valueOf(env.getProperty(keyPrefix + "idleTimeout")));
String connectionPoolName = "JPAHikari_management";
hikari.setPoolName(connectionPoolName);
// mysql wait_timeout 600seconds
hikari.setMaxLifetime(Long.valueOf(env.getProperty(keyPrefix + "maxLifetime")));
hikari.setLeakDetectionThreshold(Long.valueOf(env.getProperty(keyPrefix + "leakDetectionThreshold")));
DataSource dataSource = new HikariDataSource(hikari);
return dataSource;
}
}
第一个entityManager必须处理多个租户，因此我实现了MultiTenantConnectionProvider：
@Component
@Log4j2
public class MultiTenantConnectionProviderImpl implements MultiTenantConnectionProvider {
private static final long serialVersionUID = 3193007611085791247L;
@Autowired
private ConnectionPoolManager connectionPoolManager;
@Override
public void releaseAnyConnection(Connection connection) throws SQLException {
connection.close();
}
@Override
public Connection getAnyConnection() throws SQLException {
return connectionPoolManager.getConnection(TenantContext.TENANT_DEFAULT);
}
@Override
public Connection getConnection(String tenantId) throws SQLException {
// log.info("getConnection " + tenantId);
Connection connection = connectionPoolManager.getConnection(tenantId);
return connection;
}
@Override
public void releaseConnection(String tenantId, Connection connection) throws SQLException {
log.info("releaseConnection " + tenantId);
connection.close();
}
@Override
public boolean supportsAggressiveRelease() {
return false;
}
@Override
public boolean isUnwrappableAs(Class unwrapType) {
return false;
}
@Override
public <T> T unwrap(Class<T> unwrapType) {
return null;
}
}
这是我的ConnectionPoolManager：
@Component
@Profile({"prod"})
@Log4j2
public class ConnectionPoolManagerImpl implements ConnectionPoolManager {
@Autowired
private DataSourceCache dataSourceCache;
@Autowired
private TenantDbCache tenantDbCache;
@Autowired
private DatabaseInstanceRepository databaseInstanceRepository;
@Autowired
private PasswordEncrypt passwordEncrypt;
@Autowired
private Environment env;
@Autowired
private DataSource primaryDataSource;
@Override
public Connection getConnection(@NotNull String tenantId) {
//use second DB repository, create(or reuse) a datasource and from that get the connection
}
}
启动项目时出现此异常：

我对消息有所了解，但看不到如何告诉Spring Data REST如何使用正确的entityManager。 任何提示将不胜感激。
=========编辑========
其他信息：从DatabaseInstanceRepository中删除ConnectionPoolManagerImpl的项目开始了。看来我无法在第一个数据库的MultiTenantConnectionProvider中使用第二个数据库的存储库。
