Java Spring Boot 流程模板设计：动态节点绑定、并行串行审批、回退、关联表单、进度统计与日志生成

以下是一个基于Spring Boot的流程模板设计的伪代码示例：\n\n1. 定义流程模板实体类：\n\njava\n@Entity\npublic class ProcessTemplate {\n @Id\n private Long id;\n private String name;\n // 其他属性...\n}\n\n\n2. 定义流程节点实体类：\n\njava\n@Entity\npublic class ProcessNode {\n @Id\n private Long id;\n private String name;\n // 其他属性...\n}\n\n\n3. 定义流程实例实体类：\n\njava\n@Entity\npublic class ProcessInstance {\n @Id\n private Long id;\n private Long templateId;\n private Long currentNodeId;\n private Set<Long> assignedUserIds;\n private Set<Long> completedNodeIds;\n // 其他属性...\n}\n\n\n4. 定义流程日志实体类：\n\njava\n@Entity\npublic class ProcessLog {\n @Id\n private Long id;\n private Long processInstanceId;\n private Long nodeId;\n private Long userId;\n private Date timestamp;\n private String action;\n // 其他属性...\n}\n\n\n5. 定义流程服务类：\n\njava\n@Service\npublic class ProcessService {\n @Autowired\n private ProcessTemplateRepository templateRepository;\n \n @Autowired\n private ProcessNodeRepository nodeRepository;\n \n @Autowired\n private ProcessInstanceRepository instanceRepository;\n \n @Autowired\n private ProcessLogRepository logRepository;\n \n public void startProcess(Long templateId, Set<Long> assignedUserIds) {\n ProcessTemplate template = templateRepository.findById(templateId);\n ProcessNode startNode = nodeRepository.findStartNodeByTemplateId(templateId);\n \n ProcessInstance instance = new ProcessInstance();\n instance.setTemplateId(templateId);\n instance.setCurrentNodeId(startNode.getId());\n instance.setAssignedUserIds(assignedUserIds);\n \n instanceRepository.save(instance);\n \n ProcessLog log = new ProcessLog();\n log.setProcessInstanceId(instance.getId());\n log.setNodeId(startNode.getId());\n log.setUserId(null); // 暂时为空，表示系统操作\n log.setTimestamp(new Date());\n log.setAction("start");\n \n logRepository.save(log);\n }\n \n public void completeNode(Long processInstanceId, Long nodeId, Long userId) {\n ProcessInstance instance = instanceRepository.findById(processInstanceId);\n ProcessNode node = nodeRepository.findById(nodeId);\n \n instance.getCompletedNodeIds().add(nodeId);\n instance.setCurrentNodeId(node.getNextNodeId());\n \n instanceRepository.save(instance);\n \n ProcessLog log = new ProcessLog();\n log.setProcessInstanceId(processInstanceId);\n log.setNodeId(nodeId);\n log.setUserId(userId);\n log.setTimestamp(new Date());\n log.setAction("complete");\n \n logRepository.save(log);\n }\n \n // 其他方法...\n}\n\n\n6. 定义流程控制器：\n\njava\n@RestController\npublic class ProcessController {\n @Autowired\n private ProcessService processService;\n \n @PostMapping("/process/start")\n public void startProcess(@RequestParam Long templateId, @RequestParam Set<Long> assignedUserIds) {\n processService.startProcess(templateId, assignedUserIds);\n }\n \n @PostMapping("/process/complete")\n public void completeNode(@RequestParam Long processInstanceId, @RequestParam Long nodeId, @RequestParam Long userId) {\n processService.completeNode(processInstanceId, nodeId, userId);\n }\n \n // 其他方法...\n}\n\n\n以上示例只是一个基本的流程模板设计，实际应用中可能还需要考虑更多的细节和业务需求。你可以根据实际情况进行调整和扩展。
