Question

public interface WayPointRepository extends GraphRepository, NamedIndexRepository, RelationshipOperationsRepository {
    @Query( value = "start point=node:waypoints(\"name:{name1}\") return point", elementClass=WayPoint.class, type=QueryType.Cypher ) 
    public List getWayPointByName(@Param("name1") String name);
}

我有一个neo4j数据库，其中存储了一些带有索引“waypoints”的点，我想得到通过一些点后动态一些点。为此，我创建了占位符{name1}，

但是用动态param调用getWayPointByName给我

nested exception is java.lang.RuntimeException: org.apache.lucene.queryParser.ParseException: Cannot parse 'name:{name1}': Encountered " "}" "} "" at line 1, column 11. Was expecting one of: "TO" ... ... ... ] with root cause org.apache.lucene.queryParser.ParseException: Encountered " "}" "} "" at line 1, column 11. Was expecting one of: "TO" ... ... ...

例外

使用

start point=node:waypoints(name={name1}) return point

在字符串中没有参数替换发生。

使用Spring数据从neo4j获取动态值
