Java代码实现根据节点属性信息模糊查询节点

Neo4jUtil.java

@Component
@Slf4j
public class Neo4jUtil {
@Resource
    private Session session;

    public List<Map<String,Object>> getNodeInfoByNodeName(String nodeName) {

        List<Map<String,Object>> dataList = new ArrayList<>();
         if (StrUtil.isBlank(nodeName)) {
             return dataList;
         }

         //拼装查询语句
        String cypherSql = String.format("MATCH (n) where n.name=~ '.*%s.*' RETURN n  ", nodeName);
        Result query = session.query(cypherSql, new HashMap<>(16));

        for (Map<String, Object> map : query.queryResults()) {
            NodeModel queryNode = (NodeModel) map.get("n");
            Long neo4jId = queryNode.getId();
            String[] labels = queryNode.getLabels();
            List<Property<String, Object>> propertyList = queryNode.getPropertyList();
            Map<String,Object> dataMap = new HashMap<>(5);
            for (Property<String, Object> stringObjectProperty : propertyList) {
                dataMap.put(stringObjectProperty.getKey(), stringObjectProperty.getValue());
                dataMap.put("neo4jId",neo4jId);
                dataMap.put("labels",labels);

            }
            dataList.add(dataMap);
