目標(biāo)：若依整合activiti6

好的，上邊4篇，算是基礎(chǔ)環(huán)境的準(zhǔn)備，這篇開始終于進(jìn)入了主題，開始整合activiti。

一、首先在根目錄pom文件中聲明activiti依賴，但是要移除activiti中的mybatis依賴，因?yàn)橐呀?jīng)升級成mybatis-plus了，不清楚的往前翻一翻了解一下來龍去脈。

二、application.yml，添加如下配置，注意這是要配在spring下一層的

三、創(chuàng)建ruoyi-activiti模塊
?1、層級和包的情況如圖

?2、activiti模塊的pom，引入這兩個依賴

?3、根目錄pom，聲明activiti模塊，因?yàn)槠渌K也是做么做的，咱別特立獨(dú)行

?4、admin模塊的pom，引入activiti依賴

?5、修改RuoYiApplication.java文件

?6、運(yùn)行項(xiàng)目，如果提示act_**表不存在的話，在application-druid.yml里url參數(shù)后邊拼上nullCatalogMeansCurrent=true，我的是這樣的
url: jdbc:mysql://localhost:3306/ry_mp_activiti?useUnicode=true&characterEncoding=utf8&zeroDateTimeBehavior=convertToNull&useSSL=true&serverTimezone=GMT%2B8&rewriteBatchedStatements=true&nullCatalogMeansCurrent=true

?7、項(xiàng)目運(yùn)行起來不報錯，數(shù)據(jù)庫里會多出28張act開頭的表

四、下面加點(diǎn)代碼試試，看能不能正常用

?1、在activiti模塊的config包里創(chuàng)建ActivitiConfig.java，這是為了注入activiti的api

package com.ruoyi.act.config;

import org.activiti.engine.*;
import org.activiti.spring.ProcessEngineFactoryBean;
import org.activiti.spring.SpringProcessEngineConfiguration;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.transaction.PlatformTransactionManager;

import javax.sql.DataSource;

/**
 * @author badcat
 * @date 2021-08-23 0:22
 */
@Configuration
public class ActivitiConfig {
    @Autowired
    private DataSource dataSource;
    @Autowired
    private PlatformTransactionManager platformTransactionManager;

    private SpringProcessEngineConfiguration springProcessEngineConfiguration(){
        SpringProcessEngineConfiguration spec = new SpringProcessEngineConfiguration();
        spec.setDataSource(dataSource);
        spec.setTransactionManager(platformTransactionManager);
        spec.setDatabaseSchemaUpdate("true");
        return spec;
    }

    private ProcessEngineFactoryBean processEngine(){
        ProcessEngineFactoryBean processEngineFactoryBean = new ProcessEngineFactoryBean();
        processEngineFactoryBean.setProcessEngineConfiguration(springProcessEngineConfiguration());
        return processEngineFactoryBean;
    }


    @Bean
    public RepositoryService repositoryService() throws Exception{
        return processEngine().getObject().getRepositoryService();
    }
    @Bean
    public RuntimeService runtimeService() throws Exception{
        return processEngine().getObject().getRuntimeService();
    }
    @Bean
    public TaskService taskService() throws Exception{
        return processEngine().getObject().getTaskService();
    }
    @Bean
    public HistoryService historyService() throws Exception{
        return processEngine().getObject().getHistoryService();
    }
    @Bean
    public FormService formService() throws Exception{
        return processEngine().getObject().getFormService();
    }
    @Bean
    public IdentityService identityService() throws Exception{
        return processEngine().getObject().getIdentityService();
    }

}

?2、創(chuàng)建一個測試controller寫個部署流程的api

package com.ruoyi.act.controller;

import org.activiti.engine.RepositoryService;
import org.activiti.engine.repository.Deployment;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

/**
 * @author badcat
 * @date 2021-08-23 0:25
 */
@RestController
@RequestMapping("/act")
public class ACT_Test {
    @Autowired
    private RepositoryService repositoryService;

    /**
     * 根據(jù)文件路徑部署流程
     */
    @GetMapping("/initDeploymentBPMN")
    public String initDeploymentBPMN(){
        String filename = "BPMN/test.bpmn";
        Deployment deployment = this.repositoryService.createDeployment()
                .addClasspathResource(filename)
                .name("流程部署測試uel_v3")
                .deploy();
        return deployment.getName();
    }
}

?3、創(chuàng)建流程文件（流程文件自己想辦法搞一個，或者去我碼云上下載）
