Question

不确定我做错了什么，但是使用neo4j Rest API设置甚至基本的密码查询都不起作用。我得到一个java.lang.RuntimeException：读错为JSON''

我的设置

graphDb = new RestGraphDatabase( "http://localhost:7474/db/data/" );
queryEngine = new RestCypherQueryEngine(((RestGraphDatabase)graphDb).getRestAPI());

StringBuilder query = new StringBuilder();
query.append("match (u { id:'").append(id).append("' }) return u");

QueryResult<Map<String,Object>> result = engine.query(query.toString(), null);
//the above statement throws the runtime exception with message "Error reading as JSON '' "

我刚刚发布了2.0.0的java-rest-binding，所以请试一试。

M06不应该与Neo4j 2.0.0 final一起使用。

无法使用Neo4j Rest API进行查询 - 读取为JSON时出错“
