The #this and #root variables Functions Bean references Ternary Operator (If-Then-Else) The Elvis Operator Safe Navigation operator Collection Selection Collection Projection Expression templating Classes the bean by calling its constructor reflectively, somewhat equivalent to Java code using the new operator. To specify the actual class containing the static factory method that will be invoked to create the Spring container’s role in regard to a prototype-scoped bean is a replacement for the Java new operator. All lifecycle management past that point must be handled by the client. (For details on the lifecycle

Extensions allow to add custom operators to Flow • Collect operations are suspending functions • map operator supports asynchronous operation (no need for flatMap) since it takes a suspending function parameter reactive.executeAndAwait class PersonRepository(private val operator: TransactionalOperator) { suspend fun initDatabase() = operator.executeAndAwait { insertPerson1() insertPerson2() transactional class PersonRepository(private val operator: TransactionalOperator) { fun updatePeople() = findPeople().map(::updatePerson).transactional(operator) private fun findPeople(): Flow

Nacos-k8s 项目包含了三种类型的部署方式, 原生部署、Helm 部署、以及利用 Operator 开发的 Nacos-Operator 部署, 本文演示如何通过 Operator 方式把 Nacos 集群在 Kubernetes 部署起 来。 Operator 相较于前两种方式的优势：  通过 operator 快速构建 nacos 集群，指定简单的 cr.yaml 文件，既可以实现各种类型的 clone https://github.com/nacos-group/nacos-k8s.git 2. 进入 operator 目录, 直接使用 helm 方式安装 operator helm install nacos-operator ./chart/nacos-operator 3. 查看集群部署例子 cat config/samples/nacos_cluster.yaml apiVersion: 完成上述操作, 就可以快速的创建⼀个完整的 Nacos 集群了,更多例子以及参数可以参考: https://github.com/nacos-group/nacos-k8s/blob/master/operator Nacos 生态 < 148 Nacos 服务网格⽣态 背景 在传统的基于虚拟机的部署方式中，运维人员需要手动上传应用程序压缩包到虚拟机上，经过解压、 安装和运行等⼀系列操作之后才
