* Upgrade to 2.2.1-RC (#9741) * 补充处理所有 tenantId * 补充处理 tenantId * 处理tenantid，内部类引用的变量不能被修改，换个变量名 * 新增支持：nacos 默认的 tenant/namespaceId 为空字符串，自 nacos 2.2.0 版本起开始支持多数据源插件，为空的 ID 会在 oracle 数据库适配中出现问题 ( where tenantid = '' )，本次修改对以往程序不产生影响。 * 固定填充的ID为public，完全自定义没有太大意义，目的是在保证默认id不为空，可选填充，不配置默认照旧 * fix bug * 将通用的SQL提取到Mapper接口中，这样能很大的降低不同数据库需要重写的SQL的量，同时避免了大量的重复代码问题。 * 将原来sql中固定写死的 tenant_id = '' 修改为 tenant_id = NamespaceUtil.getNamespaceDefaultId() 。暂时没深究为什么不用问号动参而是固定写死。 * 方法提取到 mapper 接口中，顺便解决了多余 paramList 定义的（虽然这个方法好像已经弃用） * 方法迁移到接口默认实现中 * 恢复 publci id 默认值为空值 ""，等以后决策好使用默认值为 "public" 时，再设置 NAMESPACE_PUBLIC_ID_DEFAULT="public" 即可。 * 回滚 Controller 层对 tenant_id 的处理，另起PR讨论和修改。 * code style * 变量名称和注释未通过 checkStyle 检查，按规范调整。 * nacos check style 修改，无代码变动 * fix code * fix checkstyle * fix checkstyle 去除多余的 return * fix pmd * fix test unit bug * 因为将sql提取到 mapper 接口中，一些不影响sql语句运行的sql，有空格等差异，出现了test用例差异问题，逐个处理。比如（where a =? 和 where a= ?） Co-authored-by: 杨翊 SionYang <xiweng.yy@alibaba-inc.com> |

Nacos: Dynamic Naming and Configuration Service
What does it do
Nacos (official site: nacos.io) is an easy-to-use platform designed for dynamic service discovery and configuration and service management. It helps you to build cloud native applications and microservices platform easily.
Service is a first-class citizen in Nacos. Nacos supports almost all type of services，for example，Dubbo/gRPC service, Spring Cloud RESTFul service or Kubernetes service.
Nacos provides four major functions.
-
Service Discovery and Service Health Check
Nacos makes it simple for services to register themselves and to discover other services via a DNS or HTTP interface. Nacos also provides real-time health checks of services to prevent sending requests to unhealthy hosts or service instances.
-
Dynamic Configuration Management
Dynamic Configuration Service allows you to manage configurations of all services in a centralized and dynamic manner across all environments. Nacos eliminates the need to redeploy applications and services when configurations are updated, which makes configuration changes more efficient and agile.
-
Dynamic DNS Service
Nacos supports weighted routing, making it easier for you to implement mid-tier load balancing, flexible routing policies, flow control, and simple DNS resolution services in the production environment within your data center. It helps you to implement DNS-based service discovery easily and prevent applications from coupling to vendor-specific service discovery APIs.
-
Service and MetaData Management
Nacos provides an easy-to-use service dashboard to help you manage your services metadata, configuration, kubernetes DNS, service health and metrics statistics.
Quick Start
It is super easy to get started with your first project.
Deploying Nacos on cloud
You can deploy Nacos on cloud, which is the easiest and most convenient way to start Nacos.
Use the following Nacos deployment guide to see more information and deploy a stable and out-of-the-box Nacos server.
Start by the provided startup package
Step 1: Download the binary package
You can download the package from the latest stable release.
Take release nacos-server-1.0.0.zip for example:
unzip nacos-server-1.0.0.zip
cd nacos/bin
Step 2: Start Server
On the Linux/Unix/Mac platform, run the following command to start server with standalone mode:
sh startup.sh -m standalone
On the Windows platform, run the following command to start server with standalone mode. Alternatively, you can also double-click the startup.cmd to run NacosServer.
startup.cmd -m standalone
