基于jeecgboot-vue3的Flowable流程-集成仿钉钉流程（二）增加基本的发起人审批与多用户多实例

 因为这个项目license问题无法开源，更多技术支持与服务请加入我的知识星球。

1、AssigneeNode 增加approvalText

public abstract class AssigneeNode extends Node {
    // 审批对象
    private AssigneeTypeEnum assigneeType;
    // 表单内人员
    private String formUser;
    // 表单内角色
    private String formRole;
    // 审批人
    private List<String> users;
    // 审批人角色
    private List<String> roles;
    // 审批人名称
    private String approvalText;
    // 主管
    private Integer leader;
    // 组织主管
    private Integer orgLeader;
    // 发起人自选：true-单选，false-多选
    private Boolean choice;
    // 发起人自己
    private Boolean self;
    public abstract List<FlowElement> convert();
}

2、对于public List<FlowElement> convert() {流程转换，做如下调整

// 审批人
        if(this.getMulti() !=  ApprovalMultiEnum.NONE) {
        	MultiInstanceLoopCharacteristics multiInstanceLoopCharacteristics = new MultiInstanceLoopCharacteristics();
            if (this.getMulti() == ApprovalMultiEnum.SEQUENTIAL) {
                multiInstanceLoopCharacteristics.setSequential(true);
            } else if (this.getMulti() == ApprovalMultiEnum.JOINT) {
                multiInstanceLoopCharacteristics.setSequential(false);
                if (Objects.nonNull(this.getMultiPercent()) && this.getMultiPercent().compareTo(BigDecimal.ZERO) > 0) {
                    BigDecimal percent = this.getMultiPercent().divide(new BigDecimal(100), 2, RoundingMode.DOWN);
                    multiInstanceLoopCharacteristics.setCompletionCondition(String.format("${nrOfCompletedInstances/nrOfInstances >= %s}", percent));
                }
            } else if (this.getMulti() == ApprovalMultiEnum.SINGLE) {
                multiInstanceLoopCharacteristics.setSequential(false);
                multiInstanceLoopCharacteristics.setCompletionCondition("${nrOfCompletedInstances > 0}");
            }
            multiInstanceLoopCharacteristics.setElementVariable("assignee");
            multiInstanceLoopCharacteristics.setInputDataItem(String.format("${multiInstanceHandler.getUserName(execution)}"));
            userTask.setLoopCharacteristics(multiInstanceLoopCharacteristics);
            userTask.setAssignee("${assignee}");
            userTask.setCandidateUsers(this.getUsers());
            ExtensionAttribute extDataTypeAttribute =  new ExtensionAttribute();
            extDataTypeAttribute.setNamespace(ProcessConstants.NAMASPASE);
    		extDataTypeAttribute.setName("dataType");
    		extDataTypeAttribute.setValue("USERS");
    		userTask.addAttribute(extDataTypeAttribute);
    		ExtensionAttribute extTextAttribute =  new ExtensionAttribute();
    		extTextAttribute.setNamespace(ProcessConstants.NAMASPASE);
    		extTextAttribute.setName("text");
    		extTextAttribute.setValue(this.getApprovalText());
    		userTask.addAttribute(extTextAttribute);
        }
    	if(this.getAssigneeType() == AssigneeTypeEnum.SELF) {
    		userTask.setName("发起人");
    		ExtensionAttribute extAttribute =  new ExtensionAttribute();
    		extAttribute.setNamespace(ProcessConstants.NAMASPASE);
    		extAttribute.setName("dataType");
    		extAttribute.setValue("INITIATOR");
    		userTask.addAttribute(extAttribute);
    		userTask.setAssignee("${initiator}");
    	}
    	else {
    		userTask.setAssignee(String.join(",", this.getUsers()));
    	}  

3、对应多人审批增加none方式

export interface ApprovalNode extends AssigneeNode {
  // 多人审批方式
  multi: 'none' | 'sequential' | 'joint' | 'single'

4、对应人员审批采用jeecg的j-select-user-by-dept

<div style="width:100%">
            <j-select-user-by-dept 
              v-if="activeData.nobody === 'assign'"
              v-model:value="activeData.nobodyUsers" 
              :multi="true" 
              placeholder="指定人员"
              @getSelectResult="handleSelectUsers">
            </j-select-user-by-dept>
          </div>

同时上面的方法如下

const  handleSelectUsers = (options, userList) => {
    props.activeData.approvalText = options.map((user) => user.label).join(',')
}    

5、仿钉钉流程设置如下

6、生成的xml如下：
