Исключение: org.hibernate.AnnotationException: для сущности не указан идентификатор: jpa.tenants.DataSourceConfig

Question

Ниже приведена ссылка, чтобы понять «https://medium.com/swlh/multi-tenancy-implementation-using-spring-boot-hibernate-6a8e3ecb251a» учебник

package jpa.tenants;
import java.util.HashMap;
import java.util.Map;

import javax.annotation.PostConstruct;
import javax.sql.DataSource;

import org.hibernate.engine.jdbc.connections.spi.AbstractDataSourceBasedMultiTenantConnectionProviderImpl;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.ApplicationContext;
import org.springframework.stereotype.Component;

@SuppressWarnings("serial")
@Component
public class DataSourceBasedMultiTenantConnectionProviderImpl extends AbstractDataSourceBasedMultiTenantConnectionProviderImpl {
    @Autowired
    private DataSource defaultDS;

    @Autowired
    private ApplicationContext context;

    private Map<String, DataSource> map = new HashMap<>();

    boolean init = false;

    private String DEFAULT_TENANT_ID="1";

    @PostConstruct
    public void load() {
        map.put(DEFAULT_TENANT_ID, defaultDS);
    }

    @Override
    protected DataSource selectAnyDataSource() {
        return map.get(DEFAULT_TENANT_ID);
    }

    @Override
    protected DataSource selectDataSource(String tenantIdentifier) {
        if (!init) {
            init = true;
            TenantDataSource tenantDataSource = context.getBean(TenantDataSource.class);
            map.putAll(tenantDataSource.getAll());
        }
        return map.get(tenantIdentifier) != null ? map.get(tenantIdentifier) : map.get(DEFAULT_TENANT_ID);
    }
}

В результате ниже исключение:

Answer 1

Аннотация Id в классе DataSourceConfig импортирована из неправильной упаковки:

import org.springframework.data.annotation.Id;

Это должно быть

import javax.persistence.Id;
