作者: 匆匆岁月 | 来源:发表于2019-11-12 13:46 被阅读0次

    学习目标:

    • 理解SaaS的基本概念
    • 了解SAAS-HRM的基本需求和开发方式掌握Power Designer的用例图
    • 完成SAAS-HRM父模块及公共模块的环境搭建完成企业微服务中企业CRUD功能

    1. 初识SaaS

    1.1 云服务的三种模式

    1.1.1 IaaS(基础设备即服务)

    IaaS(Infrastructure as a Service),即基础设施即服务。提供给消费者的服务是对所有计算机基础设施的利用,包括处理CPU、内存、存储、网络和其他基本的计算资源,用户能够部署和运行任意软件,包括操作系统和应用程序。消费者不管理或控制任何云计算基础设施,但能控制操作系统的选择、存储空间、部署的应用,也有可能获得有限制的网络组建(例如路由器、防火墙、负载均衡器等)的控制。

    1.1.2 PaaS(平台即服务)

    Paas(Platform as a Service),即平台及服务。提供给消费者的服务是把客户端采用的开发语言和工具(例如java、python、.net等)开发的或收购的应用程序部署到供应商的云计算基础设施上去。客户不需要管理或控制底层的云基础设施,包括网络、服务器、操作系统、存储等,但客户端能控制部署的应用程序,也可能控制运行程序的托管环境配置。

    1.1.3 SaaS(软件即服务)

    SaaS(Software as a Service),即软件即服务。提供给消费者完整的软件解决方案,你可以从软件服务商处以租用或购买等方式获取软件应用,组织用户即可通过Internet连接到该应用(通常使用Web浏览器)。所有基础结构、中间件、应用软件和应用数据都位于服务器提供商的数据中心内。服务商负责管理硬件和软件,并根据适当的服务协议确保应用和数据的可用性和安全性。SaaS让组织能够通过最低前期成本的应用快速建成投产。

    1.1.4区别和联系

    1.2 SaaS的概述

    1.2.1 Saas详解

    SaaS(Software-as-a-service)的意思是软件即服务。简单说就是在线系统模式,即软件服务商提供的软件在线服务。

    1.2.2 应用领域与行业前景

    SaaS软件就适用对象而言,可以划分为针对个人的与针对企业的
    面向个人的SaaS产品:在线文档,账务管理,文件管理,日程计划、照片管理、联系人管理,等等云类型的服务
    而面向企业的SaaS产品主要包括:CRM(客户关系管理)、ERP(企业资源计划管理)、线上视频或者与群组通话会议、HRM(人力资源管理)、OA(办公系统)、外勤管理、财务管理、审批管理等。


    1.2.3 Saas与传统软件对比

    • 降低企业成本:按需购买,即租即用,无需关注软件的开发维护。
    • 软件更新迭代快速:和传统软件相比,由于saas部署在云端,使得软件的更新迭代速度加快
    • 支持远程办公:将数据存储到云后,用户即可通过任何连接到 Internet 的计算机或移动设备访问其信息

    2. SaaS-HRM 需求分析

    2.1 什么是SaaS-HRM

    SaaS-HRM是基于saas模式的人力资源管理系统。他不同于传统的人力资源软件应用,使用者只需打开浏览器即可管理上百人的薪酬、绩效、社保、入职离职。

    2.2 原型分析法

    原型分析的理念是指在获取一组基本需求之后,快速地构造出一个能够反映用户需求的初始系统原型。让用户看到 未来系统的概貌,以 便判断哪些功能是符合要求的,哪些方面还需要改进,然后不断地对这些需求进一步补充、细化和修改。依次类推,反复进行,直到用户满意为止并由此开发出完整 的系统。
    简单的说,原型分析法就是在最短的时间内,以最直观的方式获取用户最真实的需求

    2.3 UML的用例图

    2.3.1 UML统一建模语言

    Unified Modeling Language (UML)又称统一建模语言或标准建模语言,是始于1997年一个OMG标准,它是一个支持模型化和软件系统开发的图形化语言,为软件开发的所有阶段提供模型化和可视化支持,包括由需求分析到 规格,到构造和配置。 面向对象的分析与设计(OOA&D,OOAD)方法的发展在80年代末至90年代中出现了一个高潮,UML是这个高潮的产物。它不仅统一了Booch、Rumbaugh和Jacobson的表示方法,而且对其作了进一步的 发展,并最终统一为大众所接受的标准建模语言。UML中包含很多图形(用例图,类图,状态图等等),其中用例 图是最能体现系统结构的图形

    2.3.2用例图

    用例图(use case)主要用来描述用户与用例之间的关联关系。说明的是谁要使用系统,以及他们使用该系统可以做些什么。一个用例图包含了多个模型元素,如系统、参与者和用例,并且显示这些元素之间的各种关系,如泛 化、关联和依赖。它展示了一个外部用户能够观察到的系统功能模型图。


    3系统设计

    3.1开发方式

    SaaS-IHRM系统采用前后端分离的开发方式。


    后端给前端提供数据,前端负责HTML渲染(可以在服务器渲染,也可以在浏览器渲染)和用户交互。双方通过文档的形式规范接口内容

    3.2技术架构

    (1)前端技术栈
    以Node.js为核心的Vue.js前端技术生态架构
    (2)后端技术栈
    SpringBoot+SpringCloudAlibaba+SpringMVC+MyBatis

    3.3系统结构图

    执行文件启动 后,在地址栏输入http://localhost:801 即可访问API文档

    4 工程搭建

    4.1 前置知识点的说明

    Saas-HRM系统后端采用SpringBoot+SpringCloudAlibaba+SpringMVC+MyBatis
    Saas-HRM系统前端采用基于nodejs的vue框架完成编写使用element-ui组件库快速开发前端界面

    4.2 开发环境要求

    • JDK1.8
    • 数据库mysql 5.7
    • 开发工具 idea
    • maven版本3.3.9

    4.3 构建公共子模块

    (3)新建com.pyy.ihrm.common.utils.SnowflakeId,分布式ID生成器

    目前微服务架构盛行,在分布式系统中的操作中都会有一些全局性ID的需求,所以我们不能使用数据库本身的自增 功能来产生主键值,只能由程序来生成唯一的主键值。我们采用的是开源的twitter( 非官方中文惯称:推特.是国外的一个网站,是一个社交网络及微博客服务) 的snowflake (雪花)算法。


    各个段解析:

    分段 作用 说明
    1bit 保留(不用)
    41bit 时间戳,精确到毫秒 最多可以支持69年的跨度
    5bit 机器id 最多支持2的5次方(32)个节点
    5bit 业务编码 最多支持2的5次方(32)个节点
    12bit 毫秒内的计数器 每个节点每毫秒最多产生2的12次方(4096)个id

    默认情况下41bit的时间戳可以支持该算法使用到2082年,10bit的工作机器id可以支持1024台机器,序列号 支持1毫秒产生4096个自增序列id . SnowFlake的优点是,整体上按照时间自增排序,并且整个分布式系统内不会产生ID碰撞(由数据中心ID和机器ID作区分),并且效率较高,经测试,SnowFlake每秒能够产生26万ID 左右

    #分页插件配置
    pagehelper:
      helperDialect: mysql
      #分页合理化参数,默认值为false。当该参数设置为 true 时,pageNum<=0 时会查询第一页, pageNum>pages(超过总数时),会查询最后一页。默认false 时,直接根据参数进行查询
      reasonable: true
    
    #mybatis配置
    mybatis:
      type-aliases-package: com.pyy.ihrm.company.po
      mapper-locations: 'classpath:mappers/*.xml'
      configuration:
        map-underscore-to-camel-case: true
    

    (3)配置启动类

    package com.pyy.ihrm.company;
    
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    import org.springframework.context.annotation.EnableAspectJAutoProxy;
    import org.springframework.scheduling.annotation.EnableScheduling;
    import org.springframework.transaction.annotation.EnableTransactionManagement;
    import tk.mybatis.spring.annotation.MapperScan;
    
    /**
     * ========================
     * 项目启动类
     * Created with IntelliJ IDEA.
     * User:pyy
     * Date:2019/11/11 17:16
     * Version: v1.0
     * ========================
     */
    @SpringBootApplication
    @MapperScan(basePackages = {"com.pyy.ihrm.company.mapper"})
    @EnableTransactionManagement
    @EnableAspectJAutoProxy
    @EnableScheduling
    public class CompanyApplication {
    
        public static void main(String[] args) {
            SpringApplication.run(CompanyApplication.class, args);
        }
    }
    

    (4)启动SpringBoot项目访问druid, http://localhost:tomcat端口号/项目名称/druid/

    通过上面配置的用户名和密码登录:admin/admin,登录后可以查询数据源配置信息


    5.2 公共异常处理

    为了使我们的代码更容易维护,同时给用户最好的用户体验,有必要对系统中可能出现的异常进行处理。spring提供了@ControllerAdvice注解和@ExceptionHandler可以很好的在控制层对异常进行统一处理
    (1)添加自定义的异常

    package com.pyy.ihrm.company.exception;
    
    
    
    import com.pyy.ihrm.common.response.ResultCode;

    (2)配置公共异常处理

    (3)swagger配置

    package com.pyy.ihrm.company.config;
    
    import org.springframework.context.annotation.Bean;
    import org.springframework.context.annotation.Configuration;
    import org.springframework.context.annotation.Profile;
    import springfox.documentation.builders.ApiInfoBuilder;
    import springfox.documentation.builders.PathSelectors;
    import springfox.documentation.builders.RequestHandlerSelectors;
    import springfox.documentation.service.ApiInfo;
    import springfox.documentation.spi.DocumentationType;
    import springfox.documentation.spring.web.plugins.Docket;
    import springfox.documentation.swagger2.annotations.EnableSwagger2;
    
    /**
     * ========================

     * User:pyy
     * Date:2019/10/12 15:00
     * Version: v1.0
     * ========================
     */
    @Configuration
    @EnableSwagger2
    //@Profile({"local", "dev", "test"})
    public class Swagger2Configuration {
        @Bean
        public Docket createRestApi() {
            return new Docket(DocumentationType.SWAGGER_2)
                    .apiInfo(apiInfo())
                    .select()
                    .apis(RequestHandlerSelectors.basePackage("com.pyy.ihrm"))
                    .paths(PathSelectors.any())
                    .build();
        }

            return new ApiInfoBuilder()
                    .title("企业管理后台api文档")
                    .description("企业管理后台api文档")
                    .version("1.0")
                    .build();
        }
    
    }
    

    (4)跨域配置
    跨域是什么?浏览器从一个域名的网页去请求另一个域名的资源时,域名、端口、协议任一不同,都是跨域 。我们是采用前后端分离开发的,也是前后端分离部署的,必然会存在跨域问题。

    package com.pyy.ihrm.company.config;
    
    import org.springframework.context.annotation.Bean;
    import org.springframework.context.annotation.Configuration;
    import org.springframework.web.cors.CorsConfiguration;
    import org.springframework.web.cors.UrlBasedCorsConfigurationSource;
    import org.springframework.web.filter.CorsFilter;
    
    /**
     * ========================
     * 跨域配置
     * Created with IntelliJ IDEA.
     * User:pyy
     * Date:2019/10/12 15:00
     * Version: v1.0
     * ========================
     */
    @Configuration
    public class CorsConfig {
        private CorsConfiguration buildConfig() {
            CorsConfiguration corsConfiguration = new CorsConfiguration();
            corsConfiguration.addAllowedOrigin("*"); // 1允许任何域名使用
            corsConfiguration.addAllowedHeader("*"); // 2允许任何头
            corsConfiguration.addAllowedMethod("*"); // 3允许任何方法(post、get等)
            return corsConfiguration;
        }
    
        @Bean
        public CorsFilter corsFilter() {
            UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
            source.registerCorsConfiguration("/**", buildConfig()); // 4
            return new CorsFilter(source);
        }
    }

    5.3 企业管理-CRUD

    5.3.1 表结构分析

    drop table if exists company;

    );
    
    alter table company comment '企业信息';
    

    5.3.2 完成企业增删改查操作

    (1)在ihrm-company工程下创建 实体PO类

    package com.pyy.ihrm.company.po;
    
    import lombok.Data;
    
    import javax.persistence.Id;
    import javax.persistence.Table;
    import java.io.Serializable;
    
    /**
     * ---------------------------

     * 版本:  v1.0
     * ---------------------------
     */
    @Data
    @Table(name = "company")
    public class Company implements Serializable{
    
        private static final long serialVersionUID = 8294633490615151005L;
        /** ID */
        @Id
        private String id;
        /** 公司名称 */
        private String name;
        /** 当前余额 */
        private Double balance;
        /** 状态 */
        private Integer state;
        /** 审核状态 */
        private String auditState;
        /** 备注 */
        private String remarks;
        /** 所属行业 */
        private String industry;
        /** 公司规模 */
        private String companySize;
        /** 邮箱 */
        private String mailbox;
        /** 公司电话 */
        private String companyPhone;
        /** 法人代表 */
        private String legalRepresentative;
        /** 营业执照-图片ID */
        private String businessLicenseId;
        /** 公司地址 */
        private String companyAddress;
        /** 公司地区 */
        private String companyArea;
        /** 到期时间 */
        private java.util.Date expirationDate;
        /** 续期时间 */
        private java.util.Date renewalDate;
        /** 当前版本 */
        private String version;
        /** 企业登录账号ID */
        private String managerId;
        /** 创建人ID */
        private String createId;
        /** 创建人名称 */
        private String createName;
        /** 创建时间 */
        private java.util.Date createTime;
        /** 更新人ID */
        private String updateId;
        /** 更新人名称 */
        private String updateName;
        /** 更新时间 */
        private java.util.Date updateTime;
        /** 删除标记 0:正常 1:删除 */
        private Integer isDeleted;
    
    }
    

    (2)在 ihrm-common-model工程中创建 CompanyQueryConditionVO.java, CompanySaveOrUpdateVO.java,CompanyVO.java

    这里之所以将VO类放在model工程中,原因是因为后面整合其他微服务时,会用到这些公共VO类。

    CompanyQueryConditionVO.java

    package com.pyy.ihrm.domain.company.vo;
