1、下图为项目结构
2、最外层 pom引入依赖
<properties> <!--camunda 标明版本，注意要个自己的Spring 版本匹配，匹配关系自行查询官网--> <camunda.version>7.18.0</camunda.version> </properties>
3、common模块引入依赖
<!--camunda --> <dependency> <groupId>org.camunda.bpm.springboot</groupId> <artifactId>camunda-bpm-spring-boot-starter</artifactId> <version>${camunda.version}</version> </dependency> <dependency> <groupId>org.camunda.bpm.springboot</groupId> <artifactId>camunda-bpm-spring-boot-starter-rest</artifactId> <version>${camunda.version}</version> </dependency> <dependency> <groupId>org.camunda.bpm.springboot</groupId> <artifactId>camunda-bpm-spring-boot-starter-webapp</artifactId> <version>${camunda.version}</version> </dependency> <!-- Camunda BPMN模型处理 --> <dependency> <groupId>org.camunda.bpm.model</groupId> <artifactId>camunda-bpmn-model</artifactId> <version>${camunda.version}</version> </dependency> <dependency> <groupId>org.camunda.bpm</groupId> <artifactId>camunda-engine</artifactId> <version>${camunda.version}</version> </dependency>
4、yml配置
# camunda配置 camunda: bpm: #登录用户信息 admin-user: #用户名 id: demo #密码 password: demo filter: create: All tasks #指定数据类型 database: type: mysql schema-update: false #禁止自动部署resources 下面的bpmn auto-deployment-enabled: false #禁止index 跳转到Camunda 自带的管理页面，默认为true #webapp: #index-redirect-enabled: true
4、若依要跳过鉴权
security配置:跳过鉴权 .antMatchers("/camunda/**").permitAll()
5、启动类加注解 ,如下
@EnableProcessApplication 激活一系列Camunda相关的自动配置,每次启动时自动读取resource下的npmn文件5、npmn存放的位置
7、npmn文件xml和图片,其中办结节点为调用监听

10、测试用例
/**

*/
@Data
public class OaTestDemo implements Serializable {
/**

@TableId(value = "id", type = IdType.AUTO)
private Integer id;

List<TaskAudit> flowIds;
private String code;
private String taskVersion;
private String taskId;
/* 流程线*/
@TableField(exist = false)
private List<ModelFlowNodeUtilVo> flowMap;
}
以下是关键业务逻辑
发起一个任务流程实例
@Override
@Transactional(rollbackFor =RuntimeException.class)
public Integer startProcessInstanceByKey(SysUser user, OaTestDemo oaTestDemo) {
oaTestDemo.setProposerId(user.getUserId().intValue());
oaTestDemo.setProposerTime(new Date());
oaTestDemo.setUserId(user.getUserId().intValue());
oaTestDemo.setDeptId(user.getDeptId().intValue());
oaTestDemo.setStatus(0);
oaTestDemo.setCode(getCode());
oaTestDemoMapper.insert(oaTestDemo);
int id=oaTestDemo.getId();
String businessKey=business+id;
SysUser leaderInfo = userService.selectUserById(user.getLeaderId());
// 获取部门领导
SysUser deptUser=auditUtils.getDeptLeader(user);
Map<String, Object> paramMap = new HashMap<>(10);
paramMap.put("proposer",user.getUserId().toString() );
paramMap.put("lineLeader",leaderInfo.getUserId().toString() );
paramMap.put("businessId",oaTestDemo.getId().toString() );
paramMap.put("deptLeader",deptUser.getUserId().toString());
paramMap.put("flowIdea",flowIdea );
// 根据流程定义的key和版本号查找流程定义
ProcessDefinition processDefinition = repositoryService.createProcessDefinitionQuery()
.processDefinitionKey(oaTestDemo.getTaskKey()) // 替换为你的流程定义key
.processDefinitionVersion(processDefinitionService.getHighestVersionByKey(oaTestDemo.getTaskKey())) // 替换为你想要的版本号
.singleResult();
if (processDefinition == null) {
throw new RuntimeException("流程定义未找到");
}
/*
关键代码
runtimeService.startProcessInstanceById(processDefinitionId, businessKey, variables) 是Camunda BPM引擎中用于启动流程实例的一个方法。
processDefinitionId: 这个参数是一个字符串，代表你想要启动的流程定义的唯一标识符。
businessKey:这也是一个字符串参数，用于给流程实例分配一个业务键。业务键是一个可选的参数，但是它非常有用，因为它可以帮助你在业务层面唯一地标识一个流程实例。例如，如果你的应用程序中每个订单都启动了一个流程实例，你可以使用订单ID作为业务键，这样你就可以通过订单ID轻松地查询到相关的流程实例状态。
variables: 这是一个Map<String, Object>类型的参数，用于传递流程实例启动时的变量。这些变量可以被流程中的活动所使用，例如，它们可以作为任务表单的预填充值，或者用于决定流程的分支路径。
*/
ProcessInstance processInstance = runtimeService.startProcessInstanceById(processDefinition.getId(), businessKey, paramMap);
if(ObjectUtil.isNull(processInstance)){
throw new RuntimeException(ProcessExceptionEnum.START_PROCESS_INSTANCE_FAIL.getDesc());
}
// 以下代码是讲流程实例的关键信息绑定到业务表中
oaTestDemo.setActHiProcinstId(processInstance.getId());
oaTestDemo.setBusinessKey(businessKey);
oaTestDemo.setCurrentName(processInstanceService.getNowCurrentName(processInstance.getId()));
HashMap map=processInstanceService.getTaskDateBy(processInstance.getId());
oaTestDemo.setTaskVersion(map.get("taskVersion").toString());
oaTestDemo.setTaskId(map.get("taskId").toString());
oaTestDemoMapper.updateById(oaTestDemo);
taskAuditService.addAuditFlow(user,oaTestDemo,AuditInfoEnum.commit.code,flowIdea);
this.addStartTblFlowMessage(oaTestDemo,false);
return oaTestDemo.getId();
}
批准或驳回
@Override
@Transactional(rollbackFor =Exception.class)
public void approveOrRejectOaTestDemo(OaTestDemo oaTestDemo,Boolean approve) {
// 关键代码 调用流程实例的审批 processInstanceService.approveOrRejectByBusinessKeyExample(oaTestDemo.getActHiProcinstId(),oaTestDemo.getBusinessKey(),approve,flowIdea);
SysUser user = userService.selectUserById(SecurityUtils.getUserId());
Integer ifHaveNextNode= processInstanceService.ifEndTaskById(oaTestDemo.getActHiProcinstId());
}
重新提交流程实例
@Override
@Transactional(rollbackFor =RuntimeException.class)
public void againSubmit(OaTestDemo oaTestDemo) {
OaTestDemo oldTestDemo=oaTestDemoMapper.selectById(oaTestDemo.getId());
if(oldTestDemo==null){
throw new RuntimeException("未获取到数据,请确定参数是否正确");
}
if(!oldTestDemo.getProposerId().equals(SecurityUtils.getUserId().intValue())){
throw new RuntimeException("非申请人,不支持该操作");
}
// 关键代码 ,以上根据自己项目需要自行编写
// 定义需要携带的变量名列表，根据实际情况调整
Set<String> desiredVariableNames = new HashSet<>(Arrays.asList("proposer", "lineLeader", "deptLeader", "businessId"));
// processInstanceId 流程实例id
String processInstanceId= processInstanceService.RestartProcessByKeyExample(
desiredVariableNames,
oldTestDemo.getActHiProcinstId(),
oldTestDemo.getBusinessKey(),
flowIdea);
// 关键代码 ,以下根据自己项目需要自行编写
oldTestDemo.setActHiProcinstId(processInstanceId);
oaTestDemoMapper.updateById(oldTestDemo);
}
11、测试用例中我绑定的监听类
package com.yuepu.oa.comunda.controller.serviceTask;
import com.yuepu.oa.comunda.entity.OaTestDemo;
import com.yuepu.oa.mapper.OaTestDemoMapper;
import org.camunda.bpm.engine.delegate.DelegateExecution;
import org.camunda.bpm.engine.delegate.JavaDelegate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
@Service("oaTestDemoHandler")
public class OaTestDemoHandlerService implements JavaDelegate {
private final OaTestDemoMapper oaTestDemoMapper;
@Autowired
public OaTestDemoHandlerService(OaTestDemoMapper oaTestDemoMapper) {
this.oaTestDemoMapper = oaTestDemoMapper;
}
@Override
public void execute(DelegateExecution delegateExecution) throws Exception {
System.out.println("调用监听");
// 更安全的获取变量值，避免空指针异常
String businessIdStr = (String) delegateExecution.getVariable("businessId");
if (businessIdStr != null) {
Integer businessId = Integer.parseInt(businessIdStr);
OaTestDemo oaTestDemo = oaTestDemoMapper.selectById(businessId);
if (oaTestDemo == null) {
throw new RuntimeException("没有找到businessessId的匹配记录 : " + businessId);
}
// 更安全的类型转换
Boolean approved = (Boolean) delegateExecution.getVariable("approved");
if (approved != null && approved) {
oaTestDemo.setStatus(1);
oaTestDemo.setCurrentName("办结");
} else {
oaTestDemo.setStatus(2);
oaTestDemo.setCurrentName("发起人");
}
oaTestDemoMapper.updateById(oaTestDemo);
}
}
}
如果需要获取流程线,建议在启动流程实例的时候,通过一个固定变量对象存放到流程实例中,流程实例无法获取还未进行到节点的信息, 如果需要获取为执行到的节点处理人信息, 但是可以通过流程实例id获取流程变量
以下是camunda某些表作用的解释
http://localhost:8081/api/camunda/app/
ACT_HI_
表示流程历史记录
act_hi_actinst： 执行的活动历史
act_hi_taskinst：执行任务历史
act_hi_procinst：执行流程实例历史
act_hi_varinst：流程变量历史表
ACT_RE_
表示流程资源存储
act_re_procdef：流程定义存储
act_re_deployment: 自动部署，springboot每次启动都会重新部署，生成记录
ACT_RU_
表示流程运行时表数据，流程结束后会删除
act_ru_execution：运行时流程实例
act_ru_task：运行时的任务
act_ru_variable：运行时的流程变量
ACT_GE_
流程通用数据
act_ge_bytearray：每次部署的文件2进制数据，所以如果文件修改后，重启也没用，因为重新生成了记录，需要清掉数据库，或者这个表记录
登录界面
act_hi_actinst
全称: ACT_HI_ACTINST
含义: 此表存储了流程实例中每一个活动（如任务、网关等）的每一次执行的历史记录。每个流程实例中的每个活动都会在这个表中至少有一条记录，如果活动被执行多次，则会有对应多条记录。
主要字段:
ID_: 历史活动实例的唯一标识。
PROC_DEF_ID_: 关联的流程定义ID。
PROC_INST_ID_: 关联的流程实例ID。
EXECUTION_ID_: 执行实例ID，表示活动在哪一个执行路径上被执行。
ACT_ID_: 流程定义中活动的ID。
START_TIME_, END_TIME_: 活动开始和结束的时间戳。
DURATION_: 活动持续的时间。
用途: 用于审计、统计分析或追踪具体活动的执行历史，例如查看某任务何时开始、何时结束，耗时多久等。
act_hi_procinst
全称: ACT_HI_PROCINST
含义: 此表记录了每个流程实例的整体历史信息，每启动一次流程实例，就会在这个表中生成一条记录。
主要字段:
ID_: 历史流程实例的唯一标识。
PROC_DEF_ID_: 启动的流程定义ID。
BUSINESS_KEY_: 流程实例的业务键，用于关联业务数据。
START_TIME_, END_TIME_: 流程实例的启动和结束时间。
DURATION_: 流程实例的总持续时间。
START_USER_ID_: 启动流程实例的用户ID。
用途: 用于查看流程实例级别的信息，如流程实例的总体执行时间、启动者等，适合于监控流程实例的宏观状态和进行整体分析。
act_hi_actinst（执行的活动历史）
记录内容：此表记录了流程实例中每一个流程活动（如服务任务、用户任务、排他网关等）的每一次执行的详细历史信息。这包括了自动活动和人工任务的执行记录。
关键字段：包括ACTIVITY_ID_(活动ID)，PROC_INST_ID_(关联的流程实例ID)，START_TIME_和END_TIME_(活动开始和结束时间)，以及DURATION_(活动执行时长)等。
用途：用于跟踪和分析流程中各个活动的执行情况，例如了解每个活动的执行效率、耗时等，对流程优化和故障排查非常有用。
act_hi_taskinst（执行任务历史）
记录内容：专注于记录用户任务（Human Task）的执行历史，即那些需要用户交互的任务实例。这包括了任务的创建、分配、完成、取消等状态变化。
关键字段：除了包含PROC_INST_ID_(关联的流程实例ID)外，还包括TASK_DEF_KEY_(任务定义的ID)，CREATE_TIME_和CLAIM_TIME_(任务创建和认领时间)，以及COMPLETED_TIME_(任务完成时间)等。
用途：主要用于追溯和审计用户任务的处理过程，比如查看哪些任务被谁处理，处理时间等，对于管理任务分配和监控个人工作量非常有帮助。
act_hi_procinst（执行流程实例历史）
记录内容：记录整个流程实例从启动到结束的生命周期信息，包括流程实例的整体状态变化和基本信息。
关键字段：包括PROC_INST_ID_(流程实例ID)，PROC_DEF_ID_(流程定义ID)，BUSINESS_KEY_(业务键，关联外部业务数据)，START_TIME_和END_TIME_(流程实例的启动和结束时间)，以及DURATION_(流程实例总耗时)等。
用途：适用于分析流程实例的整体执行情况，比如查看流程的平均执行时间、成功率等，对于评估流程性能和优化流程设计至关重要。
总结来说，act_hi_actinst关注流程内部活动的执行细节，act_hi_taskinst专注于用户任务的生命周期管理，而act_hi_procinst则提供了流程实例从头到尾的概览信息。三者结合起来，可以提供全面的流程执行历史数据分析视角。
act_ru_execution（运行时执行实例）
记录内容：此表存储了流程实例及其所有执行路径的当前状态信息。它包含了正在运行或暂停的流程实例、活动、并行分支等的执行情况。也就是说，这个表反映了流程实例在任何给定时刻的动态视图。
关键字段：包括ID_(执行实例ID)，PROC_INST_ID_(关联的流程实例ID)，PROC_DEF_ID_(流程定义ID)，ACT_ID_(当前活动ID，如果有的话)，以及状态相关的字段如SUSPENSION_STATE_(挂起状态)、ACTUAL_START_TIME_(实际开始时间)等。
用途：主要用于流程引擎内部管理和查询当前运行中的流程实例状态，比如决定下一步应执行哪个活动，或是处理流程实例的暂停、继续等操作。
与历史表的区别
数据持久性：act_ru_execution表中的数据是临时的，随着流程实例的推进，相关记录可能会被修改或删除。而历史表（如act_hi_*系列）的数据一旦记录，通常是不会被修改或删除的，用于长期存储和历史分析。
用途不同：运行时表服务于流程引擎的运行时决策和状态管理，是流程执行的核心数据结构。历史表则服务于审计、监控、报表生成等后处理需求，帮助分析过去发生的流程行为。
数据内容：运行时表包含更多关于流程实例当前状态和执行路径的信息，而历史表则更多关注于流程实例、任务或活动的生命周期记录，尤其是它们的开始、结束和关键状态变更。
