出现异常信息时，乍一看有点摸不着头脑，但是仔细看堆栈信息不难发现java.util.ImmutableCollections.uoe(ImmutableCollections.java:142)这个信息。

java.util.ImmutableCollections.uoe(ImmutableCollections.java:142)，这表明你正在尝试对一个不可变的集合执行不支持的操作。

一看到这个其实我已经知道是哪里出问题了。

这是我的PO类：

    @ElementCollection
    @CollectionTable(name = LogisticsMaintenanceDefs.TABLE_PREFIX + "shipping_work_order_recipient_departs",
            joinColumns = @JoinColumn(name = "shipping_work_order_id", referencedColumnName = "id"))
    private List<RecipientDepart> recipientDeparts;

    @Getter
    @Setter
    @Embeddable
    @Comment("接收科室ids(当前科室以及子集)")
    public static class RecipientDepart implements Serializable {
        @Serial
        private static final long serialVersionUID = 4888206176466396699L;
        @Comment("部门id")
        @Column(name = "depart_id")
        private String departId;
    }

出问题的代码

        //区分一下是送到部门，还是送给人
        shippingWorkOrderPO.setRecipientDeparts(dto.getRecipientDeparts().stream().map(depart->{
            ShippingWorkOrderPO.RecipientDepart recipientDepart = new ShippingWorkOrderPO.RecipientDepart();
            recipientDepart.setDepartId(depart);
            return recipientDepart;
        }).toList());

stream().toList() 返回的是一个不可变的集合，需要修改为可变集合

改为：

      shippingWorkOrderPO.setRecipientDeparts(dto.getRecipientDeparts().stream().map(depart->{
            ShippingWorkOrderPO.RecipientDepart recipientDepart = new ShippingWorkOrderPO.RecipientDepart();
            recipientDepart.setDepartId(depart);
            return recipientDepart;
        }).collect(Collectors.toList()));

注：在使用@CollectionTable 一定要注意，传入的集合一定要是可变集合
