1. 简介
本文主要是java使用neo4j driver操作neo4j的模板项目及非常有用的工具类，主要包括：
- 图谱操作的http请求参数及响应参数标准数据结构定义（node，edge，graph等）
- 一次性操作多个node，多个edge或者path（graph）的模板代码工具类
- 使用
事务一次提交多个cql的使用模板 - 可以支持
连接多个neo4j实例的方法 - 使用时保证
sql注入的实现
2.项目架构
3.实现
3.1.pom文件
因为此项目使用的是jdk8,所以neo4j使用的是3.x版本，更多版本适配请参照： neo4j安装及简单实践

3.2.controller层
controller怎么写不重要，主要为了保持项目的完整性，使用时可以根据业务需求开发。
@Api(tags = "图数据库接口")
@Validated
@RestController
public class GraphController {@Autowiredprivate GraphService service;@ApiOperation("添加图谱")@PostMapping("/v1/graph")public Response<String> put(@RequestBody @Valid GraphReqDto dto) {service.post(dto);return BdResponse.success();}@ApiOperation("删除图谱")@PostMapping("/v1/graph/{label}")public Response<String> delete(@PathVariable @NotBlank String label, @RequestBody Map<String, Object> dto) {service.delete(label, dto);return BdResponse.success();}@ApiOperation("查询图谱根据label")@GetMapping("/v1/graph/{label}")public Response<GraphDbMd> queryByLabel(@PathVariable @NotBlank String label) {return Response.success(service.queryByLabel(label));}@ApiOperation("查询节点的入度节点")@GetMapping("/v1/graph-in-vertex/{label}/{id}")public Response<GraphDbMd> queryInVertexById(@PathVariable @NotBlank String label, @PathVariable @NotBlank String id) {return Response.success(service.queryAllInVertexById(label, Long.parseLong(id)));}@ApiOperation("查询节点的出度节点")@GetMapping("/v1/graph-out-vertex/{label}/{id}")public Response<GraphDbMd> queryOutVertexById(@PathVariable @NotBlank String label, @PathVariable @NotBlank String id) {return Response.success(service.
