一、背景介绍
上一篇我们已经把了neo4j的源码准备以及打包流程完成了本篇将讲解如何对neo4j进行单步调试。对于不了解如何编译打包neo4j的读者请阅读《一、Neo4j源码研究系列 - 源代码准备》。
大纲 本篇内容会先介绍neo4j的代码模块这样大家对neo4j的整体结构有一个初步的了解。后续介绍其服务的入口类以及单步调试的方式由于neo4j整个项目涉及的模块多且庞大所以我们本次主要学习其bolt模块的使用内容后续模块会慢慢介绍。
问首先bolt是什么
答 Bolt 是一种应用协议通过数据库查询语言如 Cypher执行数据库查询。如果事先bolt是什么的东西都不知道的同学推荐大家可以阅读下述内容如果还是不明白可以私信或者评论如果确实很多还是不知道或者不清楚的本人将写一篇关于bolt的内容帮助大家了解。
bolt介绍: https://neo4j.com/docs/bolt/current/bolt/。
二、模块说明
neo4j源码版本4.4
目录结构说明(关键代码处于community目录下)下图中作者认为重要的或者需要特殊说明的都添加了相关介绍如果有不清楚的或者觉得有问题的可以联系本人:
|-- community|-- batch-insert (用于批量插入)|-- bolt (neo4j自定义的客户端连接协议) 备注本此学习使用模块|-- buffers|-- capabilities|-- codegen|-- collections (neo4j自定义的数据结构, 方便内存跟踪) 备注neo4j很多数据结构都是自己重写的|-- command-line (neo4j的命令行工具)|-- common |-- community-it (neo4j 各个模块的集成测试) 备注neo4j的测试非常齐全|-- concurrent (并发工具)|-- configuration|-- consistency-check (neo4j 是具有分布式模式的该模块用于一致性检测) 备注 neo4j主要采用主备模式|-- csv|-- cypher (neo4j自定义的查询语言) 备注目前也是图数据库主流查询语言至少在GQL出来之前|-- cypher-shell |-- data-collector|-- dbms (数据库管理系统每个数据库都有这个)|-- diagnostics|-- fabric (neo4j的一种新模式采用分片存储) 备注: 如果完成大概率解除单机瓶颈值得关注|-- fulltext-index (neo4j的全文索引自己实现的)|-- graph-algo (内嵌的图算法主要是寻路类算法) 备注neo4j完整算法模块有单独一个仓库为GDS学习图算法可以仓库该仓库|-- graphdb-api (数据库的相关接口)|-- id-generator (neo4j id生成工具id的相关构建信息查看该模块)|-- import-tool (neo4j 导入工具)|-- import-util (导入工具帮助类)|-- index (neo4j的索引自己实现的索引相关代码查阅该模块)|-- io (neo4j的io读写模块) 备注该模块有neo4j的自定义的缓存设计“Muninn page cache,类操作系统提供的mmap。|-- kernel (核心模块不用多说)|-- kernal-api|-- layout (数据库的整体文件结构)|-- lock|-- logging|-- lucene-index|-- monitoring (数据库的状态监控)|-- neo4j (数据库服务相关的模块) 备注图数据库的启动入口就是在该模块|-- neo4j-exceptions (neo4j的自定义异常模块) 备注: neo4j的异常处理还是比较清晰的|-- neo4j-harness|-- procedure|-- procedure-api|-- procedure-compiler|-- push-to-cloud (将本地实例推送到neo4j的Aura) 备注各个图数据库仓库都开始云化了|-- random-values|-- record-storage-engine (neo4j存储相关的代码核心中的核心) |-- resource|-- schema (neo4j的图模式设计有点类似传统的ER图, 用于确定点和边之间的关系) 备注neo4j是schema-free的|-- security (这个模块每个数据库都需要把)|-- servers|-- server-api|-- spatial-index (主要用于地图坐标相关的) 备注neo4j的体系是真的庞大|-- ssl|-- storage-engine-api |-- storage-engine-util|-- testing (neo4j 测试的工具类)|-- token-api|-- unsafe|-- values (neo4j各个类型值的封装) 备注数据库存储不同值的支持该模块也用于cyper类型值的返回和写入|-- wal (neo4j的写前日志)|-- zstd-proxy
上述的目录结构为neo4j的第一级目录其子目录还未展开。从上述的结构我们就可以看出neo4j产品的庞大和复杂毕竟这个是一个图数据库产品。所以我们去阅读源码的时候需要分清主次关系优先理清其整体脉络而不是一开始就细扣各个实现细节这样容易让我们陷入误区并且缺少整体的观念。
三、代码调试
3.1 设置启动参数
服务启动入口类: CommunityEntryPoint
上述类所在目录 位于neo4j模块package org.neo4j.server 包下
服务启动执行参数 参数详情: -server --home-dirD:\neo4j-community-4.4.17-SNAPSHOT --config-dirD:/neo4j-community-4.4.17-SNAPSHOT/conf
其启动参数校验代码位于 CommunityEntryPoint 同级目录下的 NeoBootstrapperNeoBootstrapper的start方法主要检验挂载目录和配置文件。
参数名作用备注home-dirneo4j数据库所在的目录使用上节内容自己打包出来的安装目录config-dirneo4j数据库配置文件所在目录图服务器启动需要读取配置文件使用上节内容自己打包出来的安装目录下的配置文件
3.2 单步调试 以上为单步调试界面至于如何单步调试本篇就不做介绍了做过开发的基本都会debug。
3.3 bolt方法-连接服务端
大家其实最想要知道的就是客户端连接服务器然后执行语句研究起调用流程以下演示通过bolt协议连接服务端执行cypher语句的流程。
1.配置连接服务器 2.输入账号密码 如果账号密码输入错误服务端会出现下面的提示。
3.连接project 上述界面其实和browser使用方式是一样的只是走的bolt协议7687端口。
4.创建数据源movie-graph
执行“ :guide movie-graph” 左侧将会有提示框点击运行便可以创建movies数据。下面本人也将movies的cypher语句贴出来大家可以直接运行该语句生成movie数据。neo4j官网提供的很多不同类型的数据集比如社交网络、推荐系统等等数据源大家根据自己的需要自行下载 Movie-graph的cypher语句

在bolt模块的org.neo4j.fabric.bolt.BoltFabricDatabaseService类的executeQuery方法添加断点。neo4j会间隔的执行系统查询大家跳过即可
在Desktop执行下述语句
match(n) return n limit 10进行相关调试
我们执行的语句已经断下来了哦到这里我们就完成了neo4j的调试了下个章节我们将介绍其执行的流程。
四、感想
写文章有时是分享、有时是总结但是如果要写好一篇文章需要投入的大量的精力和个人时间并且你还看不到任何收益和回报这也是为什么有些人写到后面基本就不写了毕竟这个行为逆人性。有点吐槽了不管怎么样希望大家可以学到东西吧文章本人还是会不定期的更新。
