一：SpringBoot集成

1.1：pom.xml

因camunda集成SpringBoot对SpringBoot的版本和JDK的版本都有一定的要求，所以这里贴个完整的依赖。可以去官网找每个SpringBoot的版本对应的camunda版本。

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd"><modelVersion>4.0.0</modelVersion><parent><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-parent</artifactId><version>2.6.4</version><relativePath/> <!-- lookup parent from repository --></parent><groupId>com.example</groupId><artifactId>springboot-camunda</artifactId><version>0.0.1-SNAPSHOT</version><name>springboot-camunda</name><description>springboot-camunda</description><properties><camunda.spring-boot.version>7.17.0</camunda.spring-boot.version><maven.compiler.source>1.8</maven.compiler.source><maven.compiler.target>1.8</maven.compiler.target></properties><dependencies><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter</artifactId></dependency><dependency><groupId>org.camunda.bpm.springboot</groupId><artifactId>camunda-bpm-spring-boot-starter</artifactId><version>${camunda.spring-boot.version}</version></dependency><dependency><groupId>org.camunda.bpm.springboot</groupId><artifactId>camunda-bpm-spring-boot-starter-webapp</artifactId><version>${camunda.spring-boot.version}</version></dependency><dependency><groupId>org.camunda.bpm.springboot</groupId><artifactId>camunda-bpm-spring-boot-starter-rest</artifactId><version>${camunda.spring-boot.version}</version></dependency><dependency><groupId>org.camunda.bpm.springboot</groupId><artifactId>camunda-bpm-spring-boot-starter-external-task-client</artifactId><version>${camunda.spring-boot.version}</version></dependency><dependency><groupId>org.mybatis.spring.boot</groupId><artifactId>mybatis-spring-boot-starter</artifactId><version>2.2.0</version></dependency><dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId><version>8.0.32</version></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-test</artifactId><scope>test</scope></dependency></dependencies><build><plugins><plugin><groupId>org.springframework.boot</groupId><artifactId>spring-boot-maven-plugin</artifactId></plugin></plugins></build></project>

1.2：application.yml

1.3：src/main/resources/META-INF/processes.xml

<?xml version="1.0" encoding="UTF-8"?>
<process-applicationxmlns="http://www.camunda.org/schema/1.0/ProcessApplication"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"><process-archive><process-engine>default</process-engine><properties><!--<property name="resource">D:/scripts</property>--><property name="isDeleteUponUndeploy">false</property><property name="isScanForProcessDefinitions">true</property></properties></process-archive></process-application>

1.4：bpmn

将bpmn文件放到src/main/resources/bpmn目录下。

1.5：部署启动

启动项目时会自动生成表结构，数据库先创建好。

Deployment deploy = repositoryService.createDeployment().name("请假流程").addClasspathResource("bpmn/diagram_1.bpmn").deploy();
// 赋值给StartEvent中的Initiator变量中的值。
identityService.setAuthenticatedUserId("huihui");
ProcessInstance processInstance = runtimeService.startProcessInstanceByKey("HelloWordProcess");Task task = taskService.createTaskQuery().processInstanceId(processInstance.getId()).singleResult();
taskService.complete(task.getId());

可以看到表结构比activiti6多了很多。

二：用户-组-租户

// 1.创建用户
User user = identityService.newUser("huihui");
user.setId("1");
user.setFirstName("hui");
user.setLastName("hui");
user.setEmail("huihui@163.com");
user.setPassword("123456");
identityService.saveUser(user);// 2.创建组
Group group1 = identityService.newGroup("group1");
group1.setName("人力资源部");
group1.setType("1");
identityService.saveGroup(group1);// 3.绑定用户和组的关联关系
identityService.createMembership(user.getId(), group1.getId());// 4.创建租户
Tenant tenant = identityService.newTenant("app1");
tenant.setName("应用程序1");
identityService.saveTenant(tenant);// 5.绑定用户ID和租户ID关联关系
identityService.createTenantUserMembership(tenant.getId(), user.getId());
// 6.绑定组ID和租户ID关联关系
identityService.createTenantGroupMembership(tenant.getId(), group1.getId());
