zuihou-admin-cloud SaaS型微服务快速开发平台

AUR GitHub stars star GitHub forks fork

简介

基于SpringCloud(Hoxton.SR7) + SpringBoot(2.2.9.RELEASE) 的 SaaS型微服务快速开发平台,具备用户管理、资源权限管理、网关统一鉴权、Xss防跨站攻击、自动代码生成、多存储系统、分布式事务、分布式定时任务等多个模块,支持多业务系统并行开发, 支持多服务并行开发,可以作为后端服务的开发脚手架。代码简洁,架构清晰,非常适合学习使用。核心技术采用Nacos、Fegin、Ribbon、Zuul、Hystrix、JWT Token、Mybatis、SpringBoot、Seata、Nacos、Sentinel、 RabbitMQ、FastDFS等主要框架和中间件。

希望能努力打造一套从 SaaS基础框架 - 分布式微服务架构 - 持续集成 - 系统监测 的解决方案。本项目旨在实现基础能力,不涉及具体业务。

分支介绍

  1. master 分支为最新的稳定版本,每次提交都会升级一个版本号
  2. dev 分支为作者的开发分支,作者开发的最新功能会实时提交上来,喜欢尝鲜的可以切换为dev。 但可能有报错、漏提等,对项目不是很熟的朋友千万别尝试。
  3. tag 每个固定的版本都会打一个tag方便后续切换任意版本。

模式介绍

本项目可以通过配置,轻松切换项目的 租户模式

租户模式 描述 优点 缺点
NONE(非租户模式) 没有租户 简单、适合独立系统 缺少租户系统的优点
COLUMN(字段模式) 租户共用一个数据库,在业务表中增加字段来区分 简单、不复杂、开发无感知 数据隔离性差、安全性差、数据备份和恢复困难、
SCHEMA(独立schema) 每个租户独立一个 数据库(schema),执行sql时,动态在表名前增加schema 简单、开发无感知、数据隔离性好 配置文件中必须配置数据库的root账号、不支持复杂sql和 sql嵌套自定义函数
DATASOURCE(独立数据源) 每个租户独立一个 数据库(数据源),执行代码时,动态切换数据源 可独立部署数据库,数据隔离性好、扩展性高、故障影响小 相对复杂、开发需要注意切换数据源时的事务问题、需要较多的数据库
模式\描述 表中有无租户字段 实体类中有无租户字段 分布式事务 有几个数据库
NONE 支持 zuihou_defaults

zuihou-admin-cloud 演示地址 (服务器没法备案,只能加上端口~~~)

项目 演示地址 管理员账号 普通账号
租户后台 http://tangyh.top:10000/zuihou-ui/ zuihou/zuihou test/zuiou
开发&运营后台 http://tangyh.top:180/zuihou-admin-ui/ demoAdmin/zuihou

演示环境中内置租户没有写入权限,若要在演示环境测试增删改,请到开发&运营后台自行创建租户后测试

租户后台 和 开发&运营后台 2者之间的关系是什么?
A公司 使用这套SaaS脚手架二次开发了一个OA或者商城, B和C公司想使用A公司开发的这套系统,但土豪公司B有钱想要个性化功能,C公司是个穷逼,不愿意多花钱
于是,A公司就在 zuihou-admin-ui(开发&运营后台) 上新建了 租户B 和租户C, 并各自新建了账号b1和账号c1, 分别给B公司和C公司 试用,
B公司和C公司分别拿着账号, 在 zuihou-ui(租户后台) 上试用, 试用很满意,但土豪B公司先要定制功能, 就跟A公司签了一个500W的定制大单,并要求独立部署在他们自己的服务器 
穷逼C公司没钱, 就花了20W使用A公司部署的云环境, 服务器和数据等都存在A公司的云服务器上。

功能点介绍:

  1. 服务注册&发现与调用:

    基于Nacos来实现的服务注册与发现,使用使用Feign来实现服务互调, 可以做到使用HTTP请求远程调用时能与调用本地方法一样的编码体验,开发者完全感知不到这是远程方法,更感知不到这是个HTTP请求。

  2. 服务鉴权:

    通过JWT的方式来加强服务之间调度的权限验证,保证内部服务的安全性。

  3. 负载均衡:

    将服务保留的rest进行代理和网关控制,除了平常经常使用的node.js、nginx外,Spring Cloud系列的zuul和ribbon,可以帮我们进行正常的网关管控和负载均衡。其中扩展和借鉴国外项目的扩展基于JWT的Zuul限流插件,方面进行限流。

  4. 熔断机制:

    因为采取了服务的分布,为了避免服务之间的调用“雪崩”,采用了Hystrix的作为熔断器,避免了服务之间的“雪崩”。

  5. 监控:

    利用Spring Boot Admin 来监控各个独立Service的运行状态;利用turbine来实时查看接口的运行状态和调用频率;通过Zipkin来查看各个服务之间的调用链等。

  6. 链路调用监控:

    利用Zipkin实现微服务的全链路性能监控, 从整体维度到局部维度展示各项指标,将跨应用的所有调用链性能信息集中展现,可方便度量整体和局部性能,并且方便找到故障产生的源头,生产上可极大缩短故障排除时间。有了它,我们能做到:

    请求链路追踪,故障快速定位:可以通过调用链结合业务日志快速定位错误信息。 可视化:各个阶段耗时,进行性能分析。 依赖优化:各个调用环节的可用性、梳理服务依赖关系以及优化。 数据分析,优化链路:可以得到用户的行为路径,汇总分析应用在很多业务场景。

  7. 数据权限

    利用基于Mybatis的DataScopeInterceptor拦截器实现了简单的数据权限

  8. SaaS(多租户)的无感解决方案

    使用Mybatis拦截器实现对所有SQL的拦截,修改默认的Schema,从而实现多租户数据隔离的目的。 并且支持可插拔。

  9. 二级缓存

    采用J2Cache操作缓存,第一级缓存使用内存(Caffeine),第二级缓存使用 Redis。 由于大量的缓存读取会导致 L2 的网络成为整个系统的瓶颈,因此 L1 的目标是降低对 L2 的读取次数。 该缓存框架主要用于集群环境中。单机也可使用,用于避免应用重启导致的缓存冷启动后对后端业务的冲击。

  10. 优雅的Bean转换

    采用Dozer组件来对 DTO、DO、PO等对象的优化转换

  11. 前后端统一表单验证

    严谨的表单验证通常需要 前端+后端同时验证, 但传统的项目,均只能前后端各做一次检验, 后期规则变更,又得前后端同时修改。 故在hibernate-validator的基础上封装了zuihou-validator-starter起步依赖,提供一个通用接口,可以获取需要校验表单的规则,然后前端使用后端返回的规则, 以后若规则改变,只需要后端修改即可。

  12. 防跨站脚本攻击(XSS)

    • 通过过滤器对所有请求中的 表单参数 进行过滤
    • 通过Json反序列化器实现对所有 application/json 类型的参数 进行过滤
  13. 当前登录用户信息注入器

    • 通过注解实现用户身份注入
  14. 在线API

    由于原生swagger-ui某些功能支持不够友好,故采用了国内开源的swagger-bootstrap-ui,并制作了stater,方便springboot用户使用。

  15. 代码生成器

    基于Mybatis-plus-generator自定义了一套代码生成器, 通过配置数据库字段的注释,自动生成枚举类、数据字典注解、SaveDTO、UpdateDTO、表单验证规则注解、Swagger注解等。

  16. 定时任务调度器

    基于xxl-jobs进行了功能增强。(如:指定时间发送任务、执行器和调度器合并项目、多数据源)

  17. 大文件/断点/分片续传

    前端采用webupload.js、后端采用NIO实现了大文件断点分片续传,启动Eureka、Zuul、File服务后,直接打开docs/chunkUploadDemo/demo.html即可进行测试。 经测试,本地限制堆栈最大内存128M启动File服务,5分钟内能成功上传4.6G+的大文件,正式服耗时则会受到用户带宽和服务器带宽的影响,时间比较长。

  18. 分布式事务

    集成了阿里的分布式事务中间件:seata,以 高效 并且对业务 0侵入 的方式,解决 微服务 场景下面临的分布式事务问题。

  19. 跨表、跨库、跨服务的关联数据自动注入器

    用于解决跨表、跨库、跨服务分页数据的属性或单个对象的属性 回显关联数据之痛, 支持对静态数据属性(数据字典)、动态主键数据进行自动注入。

  20. 灰度发布

    为了解决频繁的服务更新上线,版本回退,快速迭代,公司内部协同开发,本项目采用修改ribbon的负载均衡策略来实现来灰度发布。
