Spring Boot 2.6 集成 Activity 7：流程部署、查询、代办、高亮功能实现

要将 Activity 7 与 Spring Boot 2.6 集成并提供流程部署、流程详情查询、当前登录人代办、流程高亮等功能，可以按照以下步骤进行操作：\n\n1. 创建一个 Spring Boot 项目，添加相应的依赖：\nxml\n<dependency>\n <groupId>org.springframework.boot</groupId>\n <artifactId>spring-boot-starter-activiti</artifactId>\n</dependency>\n\n\n2. 在 application.properties 文件中配置数据库连接等相关信息：\nproperties\n# 数据库连接配置\nspring.datasource.url=jdbc:mysql://localhost:3306/activiti?useUnicode=true&characterEncoding=utf8&zeroDateTimeBehavior=convertToNull&useSSL=false\nspring.datasource.username=root\nspring.datasource.password=root\nspring.datasource.driver-class-name=com.mysql.jdbc.Driver\n\n# Activiti 配置\nspring.activiti.database-schema-update=update\nspring.activiti.async-executor-activate=true\nspring.activiti.check-process-definitions=true\n\n\n3. 创建一个 Spring Boot 的启动类，添加 @EnableActiviti 注解启用 Activiti 的自动配置。\n\n4. 创建一个 Controller 类，实现流程的部署、流程详情查询、当前登录人代办、流程高亮等功能。例如：\njava\n@RestController\n@RequestMapping("/activiti")\npublic class ActivitiController {\n\n @Autowired\n private RepositoryService repositoryService;\n\n @Autowired\n private RuntimeService runtimeService;\n\n @Autowired\n private TaskService taskService;\n\n @Autowired\n private HistoryService historyService;\n\n @Autowired\n private ProcessEngine processEngine;\n\n // 部署流程\n @PostMapping("/deploy")\n public String deployProcess(@RequestParam("bpmnFile") MultipartFile bpmnFile) throws IOException {\n Deployment deployment = repositoryService.createDeployment()\n .addInputStream(bpmnFile.getOriginalFilename(), bpmnFile.getInputStream())\n .deploy();\n return "流程部署成功，部署 ID：" + deployment.getId();\n }\n\n // 查询流程详情\n @GetMapping("/process/{processDefinitionId}")\n public String getProcessDetail(@PathVariable String processDefinitionId) {\n ProcessDefinition processDefinition = repositoryService.createProcessDefinitionQuery()\n .processDefinitionId(processDefinitionId)\n .singleResult();\n return "流程名称：" + processDefinition.getName() + "，流程版本：" + processDefinition.getVersion();\n }\n\n // 查询当前登录人代办任务\n @GetMapping("/tasks")\n public List<String> getTasks() {\n String assignee = "当前登录人";\n List<Task> tasks = taskService.createTaskQuery()\n .taskAssignee(assignee)\n .list();\n return tasks.stream()\n .map(Task::getName)\n .collect(Collectors.toList());\n }\n\n // 流程高亮\n @GetMapping("/highlight/{processInstanceId}")\n public void highlightProcessInstance(@PathVariable String processInstanceId, HttpServletResponse response) throws IOException {\n BpmnModel bpmnModel = processEngine.getRepositoryService().getBpmnModel(processInstanceId);\n ProcessDiagramGenerator diagramGenerator = processEngine.getProcessEngineConfiguration().getProcessDiagramGenerator();\n InputStream inputStream = diagramGenerator.generateDiagram(bpmnModel, "png", runtimeService.getActiveActivityIds(processInstanceId));\n response.setContentType("image/png");\n IOUtils.copy(inputStream, response.getOutputStream());\n }\n}\n\n\n以上代码仅为示例，你可以根据具体需求进行修改和完善。\n\n注意：在部署流程时，需要将 BPMN 文件上传到服务器，并通过 MultipartFile 进行接收。流程详情查询、当前登录人代办、流程高亮等功能的具体实现需要根据你的业务逻辑和需求进行开发。
