如果是更新已经存在的记录里面的某个字段，可以这样实现：

 SolrInputDocument updateDocument = new SolrInputDocument();
            updateDocument.addField("FEATUREID", requestAddLayerElementDisable.getLayerName() + "_" + requestAddLayerElementDisable.getElement());//类似于id
            Map<String, Object> operationMap = new HashMap<String, Object>();
            operationMap.put("set", false);//要设置的值
            updateDocument.addField("VISIBLE", operationMap);//要更新的字段
            SolrUtil.addByDoc(updateDocument, jmsConfig.getSolrUrl());
