使用spring-boot正确设置多租户数据库配置的事务管理器

@Configuration
@EnableTransactionManagement
public class MultiTenantDataSourceConfig {

    // 配置第一个数据源
    @Bean
    @ConfigurationProperties(prefix = "spring.datasource.tenant1")
    public DataSource tenant1DataSource() {
        return DataSourceBuilder.create().build();
    }

    // 配置第二个数据源
    @Bean
    @ConfigurationProperties(prefix = "spring.datasource.tenant2")
    public DataSource tenant2DataSource() {
        return DataSourceBuilder.create().build();
    }

    // 创建多租户数据源路由
    @Bean
    public AbstractRoutingDataSource multiTenantDataSource() {
        Map<Object, Object> targetDataSources = new HashMap<>();
        targetDataSources.put("tenant1", tenant1DataSource());
        targetDataSources.put("tenant2", tenant2DataSource());

        MultiTenantDataSourceRouter dataSourceRouter = new MultiTenantDataSourceRouter();
        dataSourceRouter.setDefaultTargetDataSource(tenant1DataSource());
        dataSourceRouter.setTargetDataSources(targetDataSources);

        return dataSourceRouter;
    }

    // 配置事务管理器
    @Bean
    public PlatformTransactionManager transactionManager() {
        return new DataSourceTransactionManager(multiTenantDataSource());
    }
}
