如下步骤照着抄就完事了。

一、新建一个spring boot项目，并引入相关依赖

  1. <?xml version="1.0" encoding="UTF-8"?>
  2. <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  3.          xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd">

  7.         <artifactId>spring-boot-starter-parent</artifactId>
  8.         <version>2.3.0.RELEASE</version>
  9.         <relativePath/> <!-- lookup parent from repository -->
  10.     </parent>
  11.     <groupId>com.example</groupId>
  12.     <artifactId>demo</artifactId>

  58.             <scope>test</scope>

  60.     </dependencies>
  61.  
  62.     <build>

  68.         </plugins>
  69.     </build>
  70.  
  71. </project>

二、application.yml配置

  1. server:
  2.   port: 8080
  3. spring:
  4.   datasource:
  5.     driver-class-name: com.mysql.jdbc.Driver
  6.     url: jdbc:mysql://127.0.0.1:3306/rujun?characterEncoding=utf8&serverTimezone=UTC
  7.     username: root
  8.     password: root123
  9.   activiti:
  10.     check-process-definitions: false #关键配置，不然启动会报错

不配置会报如下错误

  1. Error starting ApplicationContext. To display the conditions report re-run your application with 'debug' enabled.
  2. 2020-06-12 18:07:57.268 ERROR 20516 --- [           main] o.s.boot.SpringApplication               : Application run failed

三、activiti.cfg.xml配置

  1. <?xml version="1.0" encoding="UTF-8"?>
  2. <beans xmlns="http://www.springframework.org/schema/beans"
  3.        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  4.        xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">
  5.     <bean id="processEngineConfiguration" class="org.activiti.engine.impl.cfg.StandaloneProcessEngineConfiguration">
  6.         <property name="jdbcUrl" value="jdbc:mysql://127.0.0.1:3306/rujun?characterEncoding=utf8&amp;serverTimezone=UTC" />
  7.         <property name="jdbcDriver" value="com.mysql.jdbc.Driver" />
  8.         <property name="jdbcUsername" value="root" />
  9.         <property name="jdbcPassword" value="root123" />
  10.         <property name="databaseSchemaUpdate" value="true" />
  11.     </bean>
  12. </beans>

四、启动类配置。

注意：以下配置是一定要加的，不然启动会报错

  1. exclude = org.activiti.spring.boot.SecurityAutoConfiguration.class

  1. package com.example.demo;
  2.  
  3. import org.springframework.boot.SpringApplication;
  4. import org.springframework.boot.autoconfigure.SpringBootApplication;
  5.  
  6. @SpringBootApplication(exclude = org.activiti.spring.boot.SecurityAutoConfiguration.class)
  7. public class DemoApplication {
  8.  
  9.     public static void main(String[] args) {
  10.         SpringApplication.run(DemoApplication.class, args);
  11.     }
  12.  
  13. }

至此，启动项目，数据库activiti相关的表就会被创建

 五、通过注解方式创建核心服务

  1. import org.activiti.engine.ProcessEngines;
  2. import org.activiti.engine.RepositoryService;
  3. import org.activiti.engine.TaskService;
  4. import org.springframework.context.annotation.Bean;
  5. import org.springframework.context.annotation.Configuration;
  6.  
  7. @Configuration
  8. public class ActivitiConfig {
  9.  
  10.     @Bean
  11.     public RepositoryService repositoryService() {
  12.         System.out.println("初始化RepositoryService");
  13.         RepositoryService repositoryService = ProcessEngines.getDefaultProcessEngine().getRepositoryService();
  14.         System.out.println(repositoryService);
  15.         return repositoryService;
  16.     }
  17.  
  18.     @Bean
  19.     public TaskService taskService() {
  20.         System.out.println("初始化TaskService");
  21.         TaskService taskService = ProcessEngines.getDefaultProcessEngine().getTaskService();
  22.         System.out.println(taskService);
  23.         return taskService;
  24.     }
  25.  
  26. }

六、测试Bean是否注入成功

  1. import org.activiti.engine.ProcessEngine;
  2. import org.activiti.engine.RepositoryService;
  3. import org.activiti.engine.TaskService;
  4. import org.junit.Test;
  5. import org.junit.runner.RunWith;
  6. import org.springframework.beans.factory.annotation.Autowired;
  7. import org.springframework.boot.test.context.SpringBootTest;
  8. import org.springframework.test.context.junit4.SpringRunner;
  9.  
  10. import javax.annotation.Resource;
  11.  
  12. @SpringBootTest
  13. @RunWith(SpringRunner.class)
  14. public class DemoApplicationTests {
  15.     @Autowired
  16.     private RepositoryService repositoryService;
  17.     @Resource
  18.     private TaskService taskService;
  19.     @Resource
  20.     private ProcessEngine processEngine;
  21.  
  22.     @Test
  23.     public void getProcessEngine() {
  24.         System.out.println("获取processEngine：" + processEngine);
  25.         System.out.println("获取RepositoryService：" + repositoryService);
  26.         System.out.println("获取TaskService：" + taskService);
  27.     }
  28.  
  29. }
