#### 创建SpringBoot项目 ####

<parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.5.7</version>
    </parent>
    
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>

#### 导入activiti依赖包 ####

由于activiti7是使用mybatis作为orm框架，我这里整合mybatis-plus，所以需要排除mybatis

<dependency>
        <groupId>org.activiti</groupId>
        <artifactId>activiti-spring-boot-starter</artifactId>
        <version>7.0.0.GA</version>
        <exclusions>
            <exclusion>
                <groupId>org.mybatis</groupId>
                <artifactId>mybatis</artifactId>
            </exclusion>
        </exclusions>
    </dependency>
    
    <dependency>
        <groupId>org.activiti</groupId>
        <artifactId>activiti-image-generator</artifactId>
        <version>7.0.0.GA</version>
    </dependency>
    
    <dependency>
        <groupId>dom4j</groupId>
        <artifactId>dom4j</artifactId>
        <version>1.1</version>
    </dependency>

#### 导入mybatis-plus依赖 ####

mysql不能忘记！！！

<dependency>
        <groupId>mysql</groupId>
        <artifactId>mysql-connector-java</artifactId>
    </dependency>
    
    
    <dependency>
        <groupId>com.baomidou</groupId>
        <artifactId>mybatis-plus-boot-starter</artifactId>
        <version>3.5.3</version>
    </dependency>

#### 单元测试 ####

<dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-test</artifactId>
    </dependency>
    
    <dependency>
        <groupId>org.junit.jupiter</groupId>
        <artifactId>junit-jupiter</artifactId>
        <scope>test</scope>
    </dependency>

#### 配置 ####

server:
      port: 9999
    spring:
      output:
        ansi:
          enabled: always #启用ansi颜色输出
      datasource:
        url: jdbc:mysql://127.0.0.1:3306/activiti?useUnicode=true&characterEncoding=utf-8&nullCatalogMeansCurrent=true
        username: root
        password: root
        driver-class-name: com.mysql.cj.jdbc.Driver
      activiti:
        database-schema-update: true
        history-level: full 
        check-process-definitions: false #是否检测resources/processes 目录
        db-history-used: true #是否创建history表

databaseSchemaUpdate配置项可以设置流程引擎启动和关闭时数据库执行的策略，databaseSchemaUpdate有以下四个值：
    
    false：false为默认值，设置为该值后，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时，将在启动时抛出异常。
    true：设置为该值后，Activiti会对数据库中所有的表进行更新，如果表不存在，则Activiti会自动创建。
    create-drop：Activiti启动时，会执行数据库表的创建操作，在Activiti关闭时，执行数据库表的删除操作。
    drop-create：Activiti启动时，执行数据库表的删除操作在Activiti关闭时，会执行数据库表的创建操作。

history-level对于历史数据，保存到何种粒度，Activiti提供了history-level属性对其进行配置。history-level属性有点像log4j的日志输出级别，该属性有以下四个值：
    
    none：不保存任何的历史数据，因此，在流程执行过程中，这是最高效的。
    activity：级别高于none，保存流程实例与流程行为，其他数据不保存。
    audit：除activity级别会保存的数据外，还会保存全部的流程任务及其属性。audit为history的默认值。
    full：保存历史数据的最高级别，除了会保存audit级别的数据外，还会保存其他全部流程相关的细节数据，包括一些流程参数等。

db-history-used为true表示使用历史表，如果不配置，则工程启动后可以检查数据库，只建立了17张表，历史表没有建立，则流程图及运行节点无法展示。

#### 测试部署 ####

package com;
    
    import com.boot.App;
    import org.activiti.engine.RepositoryService;
    import org.activiti.engine.repository.Deployment;
    import org.junit.jupiter.api.Test;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.boot.test.context.SpringBootTest;
    
    @SpringBootTest(classes = App.class)
    public class ActTest01 {
        
    
        @Autowired
        RepositoryService repositoryService;
    
        @Test
        public void test01(){
        
            Deployment deployment =
                    repositoryService
                            .createDeployment()
                            .addClasspathResource("process/MyOaLeave-01.bpmn20.xml")
                            .name("请假流程")
                            .deploy();
            System.out.println("deployment.getId() = " + deployment.getId());
            System.out.println("deployment.getName() = " + deployment.getName());
        }
    
    }
