function submitForm1() {
//RefChilde.value.selectOption 为自组件的数组对象
if (!RefChilde.value.selectOption) {
proxy.$modal.msgWarning("请选择一条信息。");
return;
form.value.exSubjectId = RefChilde.value.selectOption
.map((item) => item.id)
.join(",");
form.value.exSubjectTitle = RefChilde.value.selectOption
.map((item) => item.exTitle)
.join(",");
open1.value = false;
}
后端java实现
list.stream().map(TaskBusiness::getReceivePersonId).collect(Collectors.joining(","))
