使用Spring数据从neo4j获取动态值 [英] Getting dynamic values from neo4j using Spring data

问题描述

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，其中某些点存储在索引"waypoints"中，我想获取 通过一些点后动态地改变一些点.为此，我创建了占位符{name1}，

i have a neo4j database with some points stored in it with index "waypoints", i want to get some points dynamically after passing some points. for this i have created placeholder {name1},

但是使用动态参数调用getWayPointByName会给我

but on calling the getWayPointByName with dynamic param gives me

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

推荐答案

使用

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

在字符串中没有发生参数替换.

Within strings there is no parameter substitution happening.
