问题描述

以下查询的返回类型是什么,如何使用?我尝试了诸如PathIterable<Path>之类的几种方法,但是我总是遇到某种异常.它似乎是一个LinkedHashMap,但是还有其他更方便使用的对象类型吗?

What's the return Type of the following query and how do I use it? I tried several things like Path, Iterable<Path>, and others but I always hit some sort of exceptions. It seems to be a LinkedHashMap but are there any other handier object types that I can use?

@Query( "START u1=node:User(key= {0}), u2=node:User(key = {1}) " +
        "MATCH p = shortestPath(u1-[*]-u2) " +
        "RETURN p")
public ??? findShortestPath(String u1, String u2);

我是否缺少任何依赖关系?这是我正在使用的唯一一个:

Am I missing any dependencies? This is the only one that I'm using:

<dependency>
    <groupId>org.springframework.data</groupId>
    <artifactId>spring-data-neo4j-rest</artifactId>
    <version>2.1.0.RELEASE</version>
</dependency>

推荐答案

返回类型为EndResult<EntityPath<S, E>,其中S是路径的开始节点,E是结束类型.

The return type is EndResult<EntityPath<S, E>, where S is the start node of the path, and E the end type.
