springboot整合activity5.17版

1.引入activity的pom（排除activity自身的mybatis版本）

<!--整合activity5.17-->
<dependency>
    <groupId>org.activiti</groupId>
    <artifactId>activiti-spring</artifactId>
    <version>5.17.0</version>
</dependency>
<dependency>
    <groupId>org.activiti</groupId>
    <artifactId>activiti-engine</artifactId>
    <version>5.17.0</version>
    <exclusions>
        <exclusion>
            <groupId>org.mybatis</groupId>
            <artifactId>mybatis</artifactId>
        </exclusion>
    </exclusions>
</dependency>

2.新建workflowconfig向spring容器注入引擎和activity提供的service（ProcessTraceUtil爲自己的工具類）

import cc.mrbird.febs.workflow.utitls.ProcessTraceUtil;
import org.activiti.engine.*;
import org.activiti.engine.impl.cfg.StandaloneProcessEngineConfiguration;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

import javax.sql.DataSource;

@Configuration
public class WorkFlowConfig {

    @Autowired
    private DataSource dataSource;

    /**
     * 初始化配置，將創建28張表
     * @return
     */
    @Bean
    public StandaloneProcessEngineConfiguration processEngineConfiguration() {
        StandaloneProcessEngineConfiguration configuration = new StandaloneProcessEngineConfiguration();
        configuration.setDataSource(dataSource);
        configuration.setDatabaseSchemaUpdate(ProcessEngineConfiguration.DB_SCHEMA_UPDATE_TRUE);
        configuration.setAsyncExecutorActivate(false);
        configuration.setProcessEngineName("ouyeel");
        return configuration;
    }

    @Bean
    public ProcessEngine processEngine() {
        return processEngineConfiguration().buildProcessEngine();
    }

    @Bean
    public RepositoryService repositoryService() {
        return processEngine().getRepositoryService();
    }

    @Bean
    public RuntimeService runtimeService() {
        return processEngine().getRuntimeService();
    }

    @Bean
    public TaskService taskService() {
        return processEngine().getTaskService();
    }

    @Bean
    public HistoryService historyService() {
        return processEngine().getHistoryService();
    }

    @Bean
    public FormService formService() {
        return processEngine().getFormService();
    }

    @Bean
    public IdentityService identityService() {
        return processEngine().getIdentityService();
    }

    @Bean
    public ManagementService managementService() {
        return processEngine().getManagementService();
    }

    @Bean
    public ProcessTraceUtil processTraceUtil() {
        return new ProcessTraceUtil();
    }
}

3.附上我的完整pom文件

4.如果出現整合後數據庫沒有生成activity相關的表，可以在配置數據庫連接後面增加&nullCatalogMeansCurrent=true

參考這篇博文https://blog.csdn.net/jiaoshaoping/article/details/80748065

5.最後附上activity5.17版本的流程封裝的API：https://download.csdn.net/download/qq_15076569/12076403
