Neo4j Cypher Java Jersey未找到邮件正文撰稿人

标签: java neo4j jersey

我是neo4j和jersey的新手。我试图按照neo4j文档使用Java中的Cypher端点和Jersey来从服务器进行简单的查询[1],[2]。我的代码低于[4]。和我的pom.xml一样[5]。

我一直在遇到一个错误,我在电路板上看到了很多关于一个缺失的消息体作者的错误[6]。其中一些解决方案涉及编辑其余服务器代码和添加注释。我正在寻找一个不同的解决方案,因为我计划将neo4j服务器用作开箱即用的图形数据库。我已经包含了我的pom,因为许多其他答案建议包括解决问题的特定软件包。我尝试包括那些并看到了如此成功。

有什么想法吗?

String uri = host + "/db/data/transaction/commit";

String cypherStatements = "{\"statements\": [\"statement\":{"+query+"}]}";

WebResource resource = Client.create().resource((uri));

ClientResponse response = resource.accept(MediaType.APPLICATION_JSON)
    .type(MediaType.APPLICATION_JSON)
    .entity(cypherStatements)
    .post(ClientResponse.class);

System.out.println(String
    .format("PUT to [%s], status code [%d]", uri, response.getStatus()));

答案 0 :(得分:0)

哦,看起来你正在使用客户端,但没有正确定义端点?在这种情况下,您需要向客户端注册消息正文编写器/阅读器,自动发现仅适用于服务器端。

使用Genson,你可以this way
