若依项目分模块集成uflo2

Posted 2021-01-13 conswin

关于若依分模块创建项目可参考：https://www.cnblogs.com/conswin/p/9766186.html

了解uflo2，uflo2是一套由BSTEK自主研发的基于Java的工作流引擎，它以Spring为基础框架，采用Hibernate作为持久层，可运行于所有主流程应用服务器及流数据库之上的轻量级流程引擎。

其官方说明文档可参看：http://wiki.bsdn.org/pages/viewpage.action?pageId=30441763

下面主要记录一下若依项目中集成uflo2的具体步骤：

①、创建maven module项目取名为【ruoyi-uflo】,父项目选取若依的父项目，对应pom.xml中加入uflo依赖。记得将【ruoyi-uflo】依赖加入到【ruoyi-framework】中。

 

   <description>
        uflo2流程管理模块
   </description>
   
   <properties>
        <uflo.version>2.1.4</uflo.version>
    </properties>

   <dependencies>
          <!-- uflo2依赖包-->
       <dependency>
            <groupId>com.bstek.uflo</groupId>
            <artifactId>uflo-console</artifactId>
            <version>${uflo.version}</version>
        </dependency>
       <!-- 通用工具-->
       <dependency>
           <groupId>com.ruoyi</groupId>
           <artifactId>ruoyi-common</artifactId>
           <version>${ruoyi.version}</version>
       </dependency>
   </dependencies>

 

②、按下图所示，创建servletConfig、UfloConfig、TestEvnironmentProvide：

·      

       servletConfig具体代码：

@Configuration
public class ServletConfig {
    @Bean
    public ServletRegistrationBean buildUfloServlet(){
        return new ServletRegistrationBean(new UfloServlet(),"/uflo/*");
    }
}

    UFloConfig具体代码：

@Configuration
public class UfloConfig  {


    @Bean("localSessionFactoryBean")
    public LocalSessionFactoryBean localSessionFactoryBean(DataSource dataSource) throws
            PropertyVetoException, IOException {
        LocalSessionFactoryBean sessionFactoryBean = new LocalSessionFactoryBean();
        sessionFactoryBean.setDataSource(dataSource);
        sessionFactoryBean.setPackagesToScan("com.bstek.uflo.model*");
        Properties prop = new Properties();
        prop.put("hibernate.dialect","org.hibernate.dialect.mysql5Dialect");
        prop.put("hibernate.show_sql",false);
        prop.put("hibernate.hbm2ddl.auto","update");
        prop.put("hibernate.jdbc.batch_size",100);
        sessionFactoryBean.setHibernateProperties(prop);

        return sessionFactoryBean;
    }


    @Bean("ufloTransactionManager")
    public HibernateTransactionManager ufloTransactionManager(SessionFactory sessionFactory){
        HibernateTransactionManager hi = new HibernateTransactionManager();
        hi.setSessionFactory(sessionFactory);
        return hi;
    }


}

   TestEvnironmentProvide具体代码：

@Component
public class TestEnvironmentProvider implements EnvironmentProvider {
    @Autowired
    private SessionFactory sessionFactory;
    @Resource(name = "ufloTransactionManager")
    private PlatformTransactionManager platformTransactionManager;

    @Override
    public SessionFactory getSessionFactory() {
        return sessionFactory;
    }

    public void setSessionFactory(SessionFactory sessionFactory) {
        this.sessionFactory = sessionFactory;
    }

    @Override
    public PlatformTransactionManager getPlatformTransactionManager() {
        return platformTransactionManager;
    }

    public void setPlatformTransactionManager(PlatformTransactionManager platformTransactionManager) {
        this.platformTransactionManager = platformTransactionManager;
    }

    @Override
    public String getLoginUser() {
        return null;
    }

    @Override
    public String getCategoryId() {
        return "anonymous";
    }

}

③、打开ruoyi-admin的配置启动类RuoYiApplication.java，导入uflo的配置文件，如下代码：

@ImportResource("classpath:uflo-console-context.xml")

④、启动若依，会自动在数据库生成uflo相应的数据表，访问：【待办任务】http://localhost/uflo/todo 或者 【流程设计】http://localhost/uflo/designer来验证是否集成成功。
