    1. 项目功能架构

    1.1 项目背景

    1. 找工作的人:

      现在社会竞争压力越来愈大,很多应届毕业生毕业后没法直接胜任某类工作,或者是一些已经工作的人慢慢丧失自己学习的能力,最终导致失业无法再次就业。

    2. 招聘单位

      虽然求职者非常多,但是很多人的能力达不到用人企业的要求,他们期望一招聘进来马上就能使用,所以需要对求职候选人进行培养筛选。

    3. 培训机构

      很多培训机构虽然有能力培训人才但是,市场能力比较差,找不到合适的学员,让他们通过培训能找到工作

    正是由于以上三类场景,所以我们开发一个源码人力系统,让找工作的人,能够选择特定机构的课程学习,并参与平台发布的招聘,而且还能参与一些活动。 让招聘单位入驻进来发布岗位进行招聘,甚至委托培训机构培训合适的人才。对于配置机构可以发布课程,吸收学员来完成学习并通过收取学费获取商业价值。

    1.2 功能模块

    1.3 项目原型

    2. 项目技术架构

    2.1 技术栈

    前后端分离模式,接口规范API:Swagger

    1. 前端:Nodejs、Npm、webpack、 vue.js、vuecli、Element UI。测试使用mock
    2. 后端:微服务架构:按照功能拆分N多个服务,每个服务可以独立技术选型,独立开发,独立部署,独立运维.,单个服务使用基于ssm的springboot,服务间通过spring cloud协调。测试接口使用postman

    2.2 开发步骤

    前后端分离模式下并行开发,多人协作!开发步骤如下:

    1. 需求分析
    2. 组建团队
    3. 开发
    4. 测试
    5. 上线
    6. 运维
    7. 开发其他项目

    3. 开发环境

    前端:

    后端:

    1. idea
    2. maven 3.3.9
    3. jdk1.8
    4. windows10
    5. tomcat8
    6. mysql 5.6

    4. 后端项目微服务原型搭建

    4.1 idea指定maven配置

    4.1.1 maven配置settings.xml

    打开maven的安装目录/conf/settings.xml,修改三处地方:仓库地址、阿里云镜像、jdk1.8。我个人没有网络上网,就配置了第四处代理上网!

    1. 本地仓库路径
    <localRepository>D:/soft/repository</localRepository>
    
    1. 阿里云镜像
        <mirror>
          <id>alimaven</id>
          <name>aliyun maven</name>
          <url>http://maven.aliyun.com/nexus/content/groups/public/</url>
          <mirrorOf>central</mirrorOf>        
        </mirror>
    
    1. jdk1.8
        <profile>    
            <id>jdk-1.8</id>    
                <activation>    
                    <activeByDefault>true</activeByDefault>    
                    <jdk>1.8</jdk>    
                </activation>    
        <properties>    
        <maven.compiler.source>1.8</maven.compiler.source>    
        <maven.compiler.target>1.8</maven.compiler.target>    
        <maven.compiler.compilerVersion>1.8</maven.compiler.compilerVersion>    
        </properties>    
        </profile>
    
    1. 代理上网
        <proxy>
          <id>myproxy</id>
          <active>true</active>
          <protocol>http</protocol>
          <username>xxx</username>
          <password>xxx</password>
          <host>172.16.6.254</host>
          <port>808</port>
          <nonProxyHosts>localhost|127.0.0.1</nonProxyHosts>
        </proxy>
    

    4.1.2 idea配置maven

    打开idea,点击File-->Other settings-->Default settings-->Build,Execution,Deployment-->Build Tools-->Maven-->修改三处地方:

    1. Maven home directory:maven的安装目录
    2. User settings file:指定安装目录下/conf/settings.xml
    3. Local repository:本地仓库地址

    4.2 Maven结构

    hrm_parent
      hrm_support_parent -->springcloud微服务支持模块
        hrm_eureka
        hrm_config_server
        hrm_zuul
      hrm_basic_parent -->基础模块
        hrm_basic_util 工具
      ......

    模块名 端口
    hrm_eureka 7001
    hrm_config_server 8848
    hrm_zuul 9527
    management_parent(服务) 9001
    ...... 9999
    hrm_主站 6001
    ...... 6999

    1. 准备代码模板

    模板放在了resources下的templates目录下.我这里准备了4个模板

    client.java.vm

    package cn.wangningbo.hrm.client;
    
    import ${package.Entity}.${entity};

    import java.util.List;
    
    /**

     */
    @FeignClient(value = "ZUUL-GATEWAY", configuration = FeignClientsConfiguration.class,
            fallbackFactory = ${entity}ClientHystrixFallbackFactory.class)
    @RequestMapping("/user/${table.entityPath}" )
    public interface ${entity}Client {

        @RequestMapping(value = "/save", method = RequestMethod.POST)
        AjaxResult save(${entity} ${table.entityPath});
    
        /**

        @RequestMapping(value = "/delete/{id}", method = RequestMethod.DELETE)
        AjaxResult delete(@PathVariable("id" ) Integer id);
    
        //获取用户
        @RequestMapping("/{id}" )
            ${entity} get(@RequestParam(value = "id", required = true) Long id);
    
    
        /**

    1. 修改模板
    2. 入口类

    注意注解@MapperScan("cn.wangningbo.hrm.mapper")

    hrm_sysmanage_service的入口类

    package cn.wangningbo.hrm;
    
    import org.mybatis.spring.annotation.MapperScan;
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    import org.springframework.cloud.netflix.eureka.EnableEurekaClient;
    
    @SpringBootApplication
    @EnableEurekaClient
    @MapperScan("cn.wangningbo.hrm.mapper")
    public class SysManage9001Application {
        public static void main(String[] args) {
            SpringApplication.run(SysManage9001Application.class, args);
        }
    }
    
    1. 测试

      先启动EurekaServer7001Application的主方法,再启动SysManage9001Application的主方法,然后查看是否注册到了注册中心,浏览器访问地址:http://localhost:9001//systemdictionary/list是否可以拿到数据!

    5.4.2.4 网关配置

    1. 配置

    在hrm_zuul_9527的配置文件中加入下面的配置

    zuul:
      routes:
        sysmanage.serviceId: hrm-sysmanage # 服务名
        sysmanage.path: /sysmanage/** # 把myUser打头的所有请求都转发给user-provider
      ignored-services: "*" # 所有服务都不允许以服务名来访问
      prefix: "/services" # 加一个统一前缀
      retryable: true # 是否重试
    ribbon:
      ConnectTimeout: 250 # 连接超时时间(ms)
      ReadTimeout: 2000 # 通信超时时间(ms)
      OkToRetryOnAllOperations: true # 是否对所有操作重试
      MaxAutoRetriesNextServer: 2 # 同一服务不同实例的重试次数
      MaxAutoRetries: 1 # 同一实例的重试次数
    hystrix:
      command:
        default:
          execution:
            isolation:
              thread:
                timeoutInMillisecond: 3000 # 熔断超时时长:3000ms
    
    1. 测试

      启动EurekaServer7001Application,再启动Zuul9527Application,最后启动

      打开浏览器,按照配置文件的网关配置的方式访问资源http://localhost:9527/services/sysmanage/systemdictionary/list,这是通过网关访问资源的,拿到了就是成功!

    5.5 接口测试工具postman

    使用postman访问网关的controller层

    略过

    5.6 接口文档Swagger

    由于要生成接口文档,这样前段看着才方便,所以我这里是使用Swagger

    5.6.1 本项目hrm_sysmanage_service配置

    5.6.1.1 步骤分析

    1. 导包
    2. 配置类
    3. 测试

    5.6.1.2 步骤实现

    1. 导包
