我正在关注neo4j 空间文档以及 github 上的测试文件，以设置 neo4j 空间点层结构。我在 Windows 7 上使用 neo4j 2.0.2，克隆了空间 2.0.2。存储库并将空间插件安装到我的 \plugins 文件夹中（该插件也列在 neo4j 浏览器的插件部分下）。

我正在尝试通过执行以下代码（使用 Jersey）来设置点索引：

final String txUri = "http://localhost:7575/db/data/ext/SpatialPlugin/graphdb/addSimplePointLayer"; 
        WebResource resource = Client.create().resource( txUri );

        String payload = "{\"layer\":\"geom\", \"lat\":\"lat\", \"lon\":\"lon\"}";
            ClientResponse response = resource
                    .entity( payload )
                    .accept( MediaType.APPLICATION_JSON+"; charset=UTF-8")
                    .type( MediaType.APPLICATION_JSON )
                    .post( ClientResponse.class );

        return response.getEntity( String.class );

根据文档的要求，我在 POST 标头中包含了“accept=appliaction/json”、“Content-type=application/json”和 UTF-8 作为编码。我从 github 上的测试文件中复制了 POST 请求的正文。但是我收到状态 500 错误：

我认为这可能是我的 tomcat 服务器的问题。但是 Web 服务的其他 URL 正在按预期工作。任何帮助是极大的赞赏。
