warm-flow工作流，新增权限监听器，动态设置

本文介绍warm-flow工作流，权限监听器，办理中动态设置流程权限 

git地址：https://gitee.com/warm_4/warm-flow.git

1、实现一下接口

 public interface Listener extends Serializable { /** 开始监听器，当前任务开始前执行 */ String LISTENER_START = "start"; /** 结束监听器，当前任务完成后执行 */ String LISTENER_END = "finish"; /** 分派办理人监听器，分派后执行 */ String LISTENER_ASSIGNMENT = "assignment"; /** 权限监听器，办理任务动态设置权限 */ String LISTENER_PERMISSION = "permission"; void notify(ListenerVariable variable); } public class FinishListener implements Listener { private static final Logger log = LoggerFactory.getLogger(StartListener.class); @Override public void notify(ListenerVariable variable) { log.info("完成监听器:{}", variable); Instance instance = variable.getInstance(); Map<String, Object> testLeaveMap = variable.getVariable(); log.info("完成监听器结束;{}", "任务完成"); } } 

2、页面配置监听器，传递后台通过逗号分割不同监听器 监听器类型和监听器路径，上下一一对应 

3、参数传递

 public class PermissionListener implements Listener { private static final Logger log = LoggerFactory.getLogger(PermissionListener.class); @Override public void notify(ListenerVariable variable) { log.info("权限监听器开始;{}", variable); Instance instance = variable.getInstance(); List<NodePermission> nodePermissionList = new ArrayList<>(); NodePermission nodePermission1 = new NodePermission(); NodePermission nodePermission2 = new NodePermission(); NodePermission nodePermission3 = new NodePermission(); // 动态传入组件权限标识 nodePermission1.setNodeCode("1"); nodePermission1.setPermissionFlag("role:1,role:2,role:100"); nodePermission2.setNodeCode("2"); nodePermission2.setPermissionFlag("role:1,role:2,role:100"); nodePermission3.setNodeCode("3"); nodePermission3.setPermissionFlag("role:1,role:2,role:101"); nodePermissionList.add(nodePermission1); nodePermissionList.add(nodePermission2); nodePermissionList.add(nodePermission3); variable.setNodePermissionList(nodePermissionList); Map<String, Object> variableMap = variable.getVariable(); TestLeave testLeave = (TestLeave) variableMap.get("testLeave"); log.info("权限监听器结束"); } }
