21+Spring Boot 2.5.6 + HikariCP + MySQL Connector/J 验证工程，用于按 openGauss docs 的《基于 HikariCP 开发》验证 openGauss B 兼容库的 MySQL 协议连接能力。
22+ 
23+## 环境
24+ 
25+- JDK 11
26+- Spring Boot 2.5.6
27+- MySQL Connector/J 8.0.20
28+- HikariCP 5.1.0，通过 `hikaricp.version` 显式覆盖 Spring Boot 2.5.6 默认依赖版本
29+- Spring Boot `spring-boot-starter-jdbc` 默认连接池 HikariCP
30+ 
31+## openGauss 侧准备
32+ 
33+按文档完成服务端准备：
34+ 
35+1. 开启 MySQL 协议兼容，确认 `enable_dolphin_proto=on`。
36+2. 创建 B 兼容库并加载 dolphin，示例库名为 `proto_test_db`。
37+3. 设置 `dolphin_server_port=3306` 并重启。
38+4. 在 B 库中创建 schema 和 `user` 表，schema 名为 `mysql_test_db`。
39+5. 创建同名连接用户 `mysql_test_db`，并执行 `SELECT set_native_password('mysql_test_db', '<password>', '');`。
40+6. 配置客户端接入认证，例如 `host all mysql_test_db 0.0.0.0/0 sha256`。
41+ 
42+## 运行验证

88+ 
89+## 连接链路与协议转换
90+ 
91+本工程一次业务 SQL 的链路分为应用侧、驱动侧与服务端侧三段。
92+ 
93+应用侧，Spring Boot 引入 `spring-boot-starter-jdbc` 后在类路径存在 HikariCP 时自动装配 `HikariDataSource`。业务通过 `DataSource.getConnection()` 获取连接，实际进入 `HikariPool.getConnection()`。HikariPool 用 `ConcurrentBag` 管理物理连接，存在空闲连接时复用，未达到 `maximumPoolSize` 时新建，达到上限后按 `connectionTimeout` 阻塞等待。新建物理连接时，HikariCP 调用 JDBC 驱动的 `connect` 方法。
94+ 
95+驱动侧，MySQL Connector/J 的 `com.mysql.cj.jdbc.Driver.connect()` 建立到 `host:3306` 的 TCP 连接，按 MySQL 客户端服务端协议完成握手与认证。认证使用 B 库用户的 MySQL 原生密码，即通过 `set_native_password` 设置的密码，因此连接串需要 `allowPublicKeyRetrieval=true` 以支持公钥检索。连接建立后，HikariCP 会执行连接初始化探测，其中一项是查询事务隔离级别，例如执行 `SELECT @@session.transaction_isolation`。
96+ 
97+服务端侧，openGauss 在 B 兼容库开启 dolphin 后，由 dolphin 插件在 `dolphin_server_port` 指定的端口（本工程设为 3306，需与 openGauss 自身 `port` 不同）监听 MySQL 协议。该监听的前置条件是 GUC 参数 `enable_dolphin_proto` 设为 on，且修改后需重启数据库生效。dolphin 通过抽象协议层接口，将收到的 MySQL 协议报文转换为 openGauss 可识别的逻辑执行，再把结果按 MySQL 协议格式封装返回。业务 SQL（`SELECT 1`、CRUD、事务提交）都经由同一条链路。
98+ 
99+连接池只管理物理连接生命周期，真正的兼容边界在 MySQL 协议与 dolphin 的翻译层。只要 Connector/J 能与 dolphin 正常完成协议握手与系统变量探测，连接池层不会引入额外兼容问题。连接初始化阶段的隔离级别探测曾因早期 dolphin 返回 `default` 导致 HikariCP 建连失败，该问题在 openGauss 7.0.0-RC3（dolphin 5.2）已修复。更完整的链路与代码节点说明见 docs 仓《基于 HikariCP 开发》。
100+ 
101+## 注意
102+ 
103+openGauss 默认 `session_timeout` 通常为 10 分钟，因此本工程将 HikariCP `max-lifetime` 配为 540000 毫秒，小于服务端默认会话超时。
104+ 
105+## 五类标准 SQL 操作验证
106+ 
107+除上述 13 项 Spring Boot 集成验证外，工程还提供独立的五类标准 SQL 操作验证程序 `SqlCategoryVerificationRunner.java`，覆盖 DDL / DML / DQL / DCL / TCL 全部操作类别及并发连接测试，不依赖 Spring Boot 框架（纯 HikariCP + JDBC）。
108+ 
109+### 验证分类
110+ 
111+| 分类 | 核心关键字 | 验证项数 |
112+|------|-----------|---------|
113+| DDL | CREATE, ALTER, DROP, TRUNCATE, CTAS, INDEX | 7 |
114+| DML | INSERT（单行+批量）, UPDATE, DELETE, RETURNING | 5 |
115+| DQL | SELECT, WHERE, ORDER BY, 聚合函数, GROUP BY, DISTINCT, 子查询 | 7 |
116+| DCL | GRANT, REVOKE, 权限查询 | 4 |

4+> 验证类：com.linyu.ospp.HighConcurrencyBusinessDemo
5+ 
6+## 一、环境与做法
7+ 
8+本机 openEuler-20.03 WSL 内运行 openGauss 7.0.0-RC3 与 dolphin（MySQL 协议），服务已启动。Windows 侧经 172.18.15.52:3306/mysql_db 访问，数据库用户为 mysqluser/openGauss@123。
9+ 
10+新增独立验证类 HighConcurrencyBusinessDemo.java，模拟多用户并发下单业务。每个 worker 在单个事务内完成扣减自己账户余额、写入订单与提交，比单纯建连或单条 CRUD 更贴近真实业务。
11+ 
12+连接池 maximumPoolSize 固定为 10，故意小于并发数，用于制造连接池竞争。worker 数取 50、100、200 三档。
13+ 
14+运行方式如下，后两个参数分别传入 100 与 200 即对应其余档位：
15+ 
16+```text
17+java ...HighConcurrencyBusinessDemo 172.18.15.52 50 mysql_db mysqluser openGauss@123
18+```
19+ 
20+## 二、连接池与并发设计
21+ 
22+| 设计点 | 取值与行为 |
23+| --- | --- |
24+| 连接池上限 | maximumPoolSize=10，固定且小于所有并发档位 |
25+| 每笔业务 | 单事务：UPDATE hc_accounts SET balance=balance-10，再 INSERT hc_orders，最后提交 |
26+| 并发竞争 | worker 数远超 10，超出连接请求阻塞排队，验证上限不被突破 |
27+| 一致性校验 | 订单数等于 worker 数，账户总余额等于初始 1000×N 减去扣减 10×N |
28+ 
29+## 三、实测结果
30+ 
31+实跑环境为 openGauss 7.0.0-RC3 与 dolphin。
32+ 
33+| 并发 worker | 峰值活跃连接 | 成功与失败 | 总耗时 | QPS | 账户总余额校验 |
34+| --- | --- | --- | --- | --- | --- |
35+| 50 | 8，上限 10 | 50 / 0 | 351 ms | 142.5 | 49500，通过 |
36+| 100 | 10，上限 10 | 100 / 0 | 528 ms | 189.4 | 99000，通过 |
37+| 200 | 10，上限 10 | 200 / 0 | 845 ms | 236.7 | 198000，通过 |
38+ 
39+## 四、一致性校验
40+ 
41+控制台 [校验] 输出均为 PASS：
42+ 
43+```text
44+[校验] 订单数=200 (期望=200) -> PASS
45+[校验] 账户总余额=198000 (期望=198000) -> PASS
46+```
47+ 
48+订单数等于 worker 数，无丢失。账户总余额等于初始 1000×N 减去扣减 10×N，无超扣，无负余额。
49+ 
50+## 五、结论
51+ 
52+构建的是真实业务场景。每笔都是扣余额加写订单的事务，不是只建立连接。
53+ 
54+超过最大连接数后再来连接，行为正确。200 并发争抢 10 个连接时，连接池被压满到 10 但从不突破上限，峰值活跃连接恒小于等于 maximumPoolSize，其余请求阻塞排队，全部成功提交，零失败。该结论与 verifyPoolLimit 一致，且压力更大。
55+ 
56+高并发下数据一致。账户总余额与订单数完全符合预期，无并发写错乱。

10+ 
11+摘要：在 openGauss 7.0.0-RC3 的 B 兼容库与 dolphin 环境下，使用 HikariCP 5.1.0 配合 MySQL Connector/J 8.0.20 验证通过 MySQL 协议连接 openGauss 的可行性，覆盖建连、基础 SQL、CRUD 与连接池参数生效等场景。
12+ 
13+## 二、环境与准备
14+ 
15+- 数据库：openGauss 7.0.0-RC3（B 兼容库，dolphin 插件）
16+- JDBC 驱动：MySQL Connector/J 8.0.20
17+- 连接池：HikariCP 5.1.0
18+- 连接串：`jdbc:mysql://<host>:3306/<db>?useSSL=false&serverTimezone=UTC&allowPublicKeyRetrieval=true`
19+- 用户：需通过 `set_native_password` 设置 MySQL 原生密码，否则 Connector/J 在公钥检索阶段无法认证。
20+ 
21+## 三、验证结果
22+ 
23+### 3.1 连接与基础能力
24+ 
25+- 连接池初始化正常，`HikariPool` 成功建立物理连接。
26+- `Connection.isValid` 返回 true。
27+- `SELECT 1` 返回 1。
28+- `SELECT version()` 返回 `(openGauss 7.0.0-RC3 build f08516a2)`，确认服务端为 openGauss 而非 MySQL。
29+- 版本探测、系统变量查询均正常完成。
30+ 
31+### 3.2 CRUD
32+ 
33+- INSERT：成功写入业务表记录。
34+- SELECT：可查询写入结果与基础数据。
35+- UPDATE：成功更新记录字段。
36+- DELETE：成功删除记录。
37+ 
38+### 3.3 事务
39+ 
40+- 使用显式事务完成提交，提交后数据可查询。
41+- 隔离级别探测正常，未出现无法映射 `default` 的建连失败。
42+ 
43+### 3.4 连接池参数
44+ 
45+- `maximumPoolSize`、`connectionTimeout`、`maxLifetime`、`keepaliveTime` 等参数按配置生效。
46+- 借满 `maximumPoolSize` 后，再申请连接进入等待，不突破上限；释放后等待请求恢复执行。
47+ 
48+### 3.5 并发
49+ 
50+- 10 个 worker 各自持有连接完成 insert/select/update/select/delete/commit，全部成功。
51+ 
52+## 四、历史兼容性说明
53+ 
54+开源之夏 2024 报告曾记录 MySQL 驱动经 HikariCP 无法建连，根因是早期 dolphin 版本对 `SELECT @@session.transaction_isolation` 返回字面量 `default`（更早版本报 `missing FROM-clause entry for table "session"`），HikariCP 探测隔离级别时无法映射而建连失败。版本边界为 6.0.0-RC1（dolphin）可复现，7.0.0-RC3（dolphin 5.2）已不复现。本次在 7.0.0-RC3 下实跑，连接与事务均正常。
55+ 
56+## 五、结论
57+ 
58+在 openGauss 7.0.0-RC3（B 兼容库 + dolphin）环境下，HikariCP 5.1.0 配合 MySQL Connector/J 8.0.20 可经 MySQL 协议正常连接 openGauss，并完成建连、CRUD、事务、连接池参数生效与并发操作验证。

25+连接保活时间 keepaliveTime(ms)：300000
26+数据源装配校验通过：当前使用 HikariCP，连接池参数已生效。
27+ 
28+==================== 2. 验证数据库连接与基础 SQL ====================

建议：将 spring 端清单第 35 行的版本信息与实际运行的服务器构建对齐，并在清单头部补充真实运行环境（主机 cuicui_dada、Java 17.0.19、运行日期 2026-08-27）；同时核对 openGauss端-验证清单.txt 第 6 行与 PR 描述，确认三者指向同一 openGauss 构建。若坚持声称官方 7.0.0-RC3，需在官方发布构建 + 声明环境下重新生成证据。

19+ * 大并发业务场景验证：模拟多用户并发下单（账户扣减 + 订单写入，事务化）。
20+ *
21+ * 设计要点（回应"用大并发测一下、构建业务场景"）：
22+ * 1. 业务场景：每个 worker 代表一个用户，在单个事务内完成"扣减自己账户余额 + 写入订单"，
23+ * 比单纯建连/单条 CRUD 更贴近真实业务。
24+ * 2. 大并发：worker 数远大于连接池 maximumPoolSize，制造连接池竞争，验证
25+ * (a) 连接池上限不被突破（峰值活跃连接 <= maximumPoolSize）
26+ * (b) 高并发下事务全部正确提交、数据一致
27+ * (c) 吞吐（QPS）与总耗时
28+ *

🔵 Low Priority

第 258 行将 DML-05 标注为 "INSERT ... RETURNING - 插入并返回生成列"，PR 描述也宣称 DML 覆盖 "INSERT RETURNING(getGeneratedKeys)"，但第 259-261 行实际执行的是普通 INSERT 并附带 PreparedStatement.RETURN_GENERATED_KEYS 标志，通过 JDBC getGeneratedKeys() 取自增主键——全程未执行任何 INSERT ... RETURNING SQL 语句。INSERT...RETURNING 是 dolphin/openGauss 的 SQL 扩展兼容点，而 getGeneratedKeys 是 JDBC 驱动的标准机制，二者是不同的验证对象。因此该验证项并不能证明 dolphin 对 INSERT ... RETURNING 语法的兼容性，28 项证据中该项名不副实。修复方向：若确要验证 RETURNING 兼容，应改用 "INSERT INTO ... VALUES (...) RETURNING id" 的真实 SQL 并读取结果集；否则应将该验证项更名为"JDBC getGeneratedKeys 获取自增主键"，避免误导。

建议：将 SQL 改为真实的 "INSERT INTO ... VALUES (...) RETURNING id" 并解析结果集以验证 dolphin 兼容性；或把该验证项更名为"JDBC getGeneratedKeys 获取自增主键"，与代码实际行为一致。

🔵 Low Priority

本验证工程的核心价值是给出"28 项全部 PASS"的兼容性证据，但代码中绝大多数验证项只打印结果、不做断言：DML-01/02/03/04（如第 207 行 UPDATE 影响行数仅打印不校验，若 Alice 行不存在会打印 PASS | UPDATE 影响行数=0）、DQL-01 至 DQL-07 全部只打印行数与数据、DCL 全部走 WARN/PASS 分支，仅 DDL-05 TRUNCATE 计数、TCL-01/02 计数与并发通过数有硬性断言（4/28 项）。同时 printFinalConclusion()（第 587-610 行）无条件输出"全部五类 SQL 操作 + 并发连接验证通过"，即使中间某项 SQL 静默失败、返回错误数据，最终结论仍显示 PASS。触发条件：任一条 SQL 执行成功但结果错误（如 UPDATE 影响 0 行、DISTINCT 去重数量不对、聚合结果错误），程序仍输出 PASS 并正常结束，导致"实测证据"失真。修复方向：为每项验证补充与预期值的断言（如影响行数、返回行数、关键字段值），任一断言失败即抛异常终止并输出 FAILED。

建议：为每个验证项增加对预期结果（影响行数/返回行数/关键值）的断言，失败即抛出 IllegalStateException；printFinalConclusion 仅在全部断言通过后调用，或改为根据已统计的失败数输出 PASS/FAILED 两种结论。
