List<Map>中直接批量修改map中的内容，不循环处理

item1List.stream().map(x -> {
    x.put("recordType","default__c");
    x.put("detailId",x.get("vbeln")+"-"+x.get("posnr"));
    try {
        String vfdatstr= (String) x.get("vfdat");
        String hsdatstr= (String) x.get("hsdat");
        if(vfdatstr!="00000000" && !vfdatstr.equals("00000000") && vfdatstr!="" && vfdatstr!=null){
            System.out.println("1:vfdat!=00000000-----"+x.get("vfdat"));
            x.remove("vfdat");
            x.put("vfdat",dataspell((String) x.get("vfdat")));
        }else {
            x.remove("vfdat");
        }

        if(hsdatstr!="00000000" && !hsdatstr.equals("00000000") && hsdatstr!="" && hsdatstr!=null){
            System.out.println("1:hsdat!=00000000-----"+x.get("hsdat"));
            x.remove("hsdat");
            x.put("hsdat",dataspell((String) x.get("hsdat")));
        }else {
            x.remove("hsdat");
        }
