Bagaimana SpringBoot menyepadukan Aktiviti7

1. Gunakan idea untuk mencipta projek springboot

Perkenalkan kebergantungan yang berkaitan ke dalam fail pom.xml projek Kebergantungan khusus adalah seperti berikut

<?xml version="1.0" encoding="utf-8"?>
<project xmlns="http://maven.apache.org/pom/4.0.0" xmlns:xsi="http://www.w3.org/2001/xmlschema-instance"

konfigurasi fail 2.application.yml

Untuk dapat meletakkan jadual yang dijana oleh activiti7 ke dalam pangkalan data mysql, anda perlu menambah konfigurasi yang berkaitan pada fail konfigurasi application.yml

server:
 port: 8085
spring:
 application:
  name: spring-activiti
 datasource:
  url: jdbc:mysql://localhost:3306/activiti?useunicode=true&characterencoding=utf8&servertimezone=gmt&nullcatalogmeanscurrent=true
  username: root
  password: 123456
  driver-class-name: com.mysql.jdbc.driver
 activiti:
  #1.flase： 默认值。activiti在启动时，会对比数据库表中保存的版本，如果没有表或者版本不匹配，将抛出异常
  #2.true： activiti会对数据库中所有表进行更新操作。如果表不存在，则自动创建
  #3.create_drop： 在activiti启动时创建表，在关闭时删除表（必须手动关闭引擎，才能删除表）
  #4.drop-create： 在activiti启动时删除原来的旧表，然后在创建新表（不需要手动关闭引擎）
  database-schema-update: true
  #检测历史表是否存在
  db-history-used: true
  #记录历史等级 可配置的历史级别有none, activity, audit, full
  history-level: full
  #校验流程文件，默认校验resources下的processes文件夹里的流程文件
  check-process-definitions: false

3. Tambah konfigurasi penyepaduan rangka kerja keselamatan springsecurity

Selepas aktiviti7 disepadukan dengan springboot, rangka kerja keselamatan springsecurity disepadukan secara lalai, jadi kita perlu menyediakan maklumat konfigurasi kebenaran pengguna yang berkaitan dengan springsecurity

1) Tambahkan kelas securityutil

Satu komponen yang ditambahkan untuk melaksanakan konfigurasi rangka kerja keselamatan springsecurity dengan cepat.

@component
public class securityutil {

  private logger logger = loggerfactory.getlogger(securityutil.class);

  @autowired
  @qualifier("myuserdetailsservice")
  private userdetailsservice userdetailsservice;

  public void loginas(string username) {

    userdetails user = userdetailsservice.loaduserbyusername(username);
    if (user == null) {
      throw new illegalstateexception("user " + username + " doesn't exist, please provide a valid user");
    }
    logger.info("> logged in as: " + username);
    securitycontextholder.setcontext(new securitycontextimpl(new authentication() {
      @override
      public collection<? extends grantedauthority> getauthorities() {
        return user.getauthorities();
      }

      @override
      public object getcredentials() {
        return user.getpassword();
      }

      @override
      public object getdetails() {
        return user;
      }

      @override
      public object getprincipal() {
        return user;
      }

      @override
      public boolean isauthenticated() {
        return true;
      }

      @override
      public void setauthenticated(boolean isauthenticated) throws illegalargumentexception {

      }

      @override
      public string getname() {
        return user.getusername();
      }
    }));
    org.activiti.engine.impl.identity.authentication.setauthenticateduserid(username);
  }
}

Kelas ini boleh didapati dalam contoh yang disediakan oleh aktiviti7.

2) Tambah kelas demoapplicationconfig

Fungsinya adalah untuk mengkonfigurasi kebenaran pengguna rangka kerja springsecurity, supaya kami boleh menggunakan maklumat kebenaran pengguna dalam sistem

@configuration
public class demoapplicationconfiguration {

  private logger logger = loggerfactory.getlogger(demoapplicationconfiguration.class);

  @bean
  public userdetailsservice myuserdetailsservice() {

    inmemoryuserdetailsmanager inmemoryuserdetailsmanager = new inmemoryuserdetailsmanager();

    string[][] usersgroupsandroles = {
        {"salaboy", "password", "role_activiti_user", "group_activititeam"},
        {"ryandawsonuk", "password", "role_activiti_user", "group_activititeam"},
        {"erdemedeiros", "password", "role_activiti_user", "group_activititeam"},
        {"other", "password", "role_activiti_user", "group_otherteam"},
        {"system", "password", "role_activiti_user"},
        {"admin", "password", "role_activiti_admin"},
    };

    for (string[] user : usersgroupsandroles) {
      list<string> authoritiesstrings = arrays.aslist(arrays.copyofrange(user, 2, user.length));
      logger.info("> registering new user: " + user[0] + " with the following authorities[" + authoritiesstrings + "]");
      inmemoryuserdetailsmanager.createuser(new user(user[0], passwordencoder().encode(user[1]),
          authoritiesstrings.stream().map(s -> new simplegrantedauthority(s)).collect(collectors.tolist())));
    }


    return inmemoryuserdetailsmanager;
  }


  @bean
  public passwordencoder passwordencoder() {
    return new bcryptpasswordencoder();
  }

}

4) Buat kelas ujian

@springboottest
@slf4j
class activitiapplicationtests {

  @autowired
  private processengine processengine;

  /**
   * 流程定义的部署
   */
  @test
  public void createdeploy() { 
    repositoryservice repositoryservice = processengine.getrepositoryservice();

    deployment deployment = repositoryservice.createdeployment()
        .addclasspathresource("diagram/holiday.bpmn")//添加bpmn资源
        .addclasspathresource("diagram/holiday.png")
        .name("请假申请单流程")
        .deploy(); 
        
    log.info("流程部署id:" + deployment.getname());
    log.info("流程部署名称:" + deployment.getid());
  }
}

Keputusan berjalan:

Masalah yang dihadapi:

1) Jadual sejarah tidak akan dijana secara lalai dan

spring:
 activiti:
  #检测历史表是否存在
  db-history-used: true
  #记录历史等级 可配置的历史级别有none, activity, audit, full
  history-level: full

perlu dikonfigurasikan dalam application.yml
