1. Transformation of backend roles

else if(this.getAssigneeType() == AssigneeTypeEnum.ROLE) {
    		ExtensionAttribute extDataTypeAttribute =  new ExtensionAttribute();
    		extDataTypeAttribute.setNamespace(ProcessConstants.NAMASPASE);
    		extDataTypeAttribute.setName("dataType");
    		extDataTypeAttribute.setValue("ROLES");
    		userTask.addAttribute(extDataTypeAttribute);
    		ExtensionAttribute extTextAttribute =  new ExtensionAttribute();
    		extTextAttribute.setNamespace(ProcessConstants.NAMASPASE);
    		extTextAttribute.setName("text");
    		extTextAttribute.setValue(String.join(",", this.getApprovalText()));
    		userTask.addAttribute(extTextAttribute);
    		List<String> roleslist = this.getRoles();
    		userTask.setCandidateGroups(roleslist);
    		userTask.setAssignee("${assignee}");
    	}

2. Select the role to use jeecg components

<div v-if="dataType === 'ROLES'" style="width: 100%;">
        <j-select-role v-model:value="roleIds" :multi="false" @getSelectResult="selRole" placeholder="请选择角色"></j-select-role>
      </div>

3. Choose the right role

function selRole(option,deptList) {
    console.log("selRole option",option)
    console.log("selRole deptList",deptList)
    let groups = null;
    let text = null;
    if (option && option.length > 0) {
      userTaskForm.value.dataType = 'ROLES';
      groups = deptList.join(",") || null;
      text = option?.map(k => k.label).join(",") || null;
    } else {
      userTaskForm.value.dataType = '';
      multiLoopType.value = 'Null';
    }
    userTaskForm.value.candidateGroups = groups;
    userTaskForm.value.text = text;
    updateElementTask();
    changeMultiLoopType();
  }

4. Update approvalNode information at the same time

else if (assigneeType === 'role') {
    console.log("assigneeType === 'role'")
    if (roles.length > 0) {
      const all = roles.map((id) => getRoleById({id: id}).then(res => {
          console.log("getRoleById res",res)
          if(res.code === 200) {
            return res.result.roleName;
          }
        })  
      ) 
      Promise.all(all).then((roles) => {
        console.log("all roles",roles)
        content.value = roles.map((role) => role).join('、')
      })
    }
