反应式关系数据库连接 SQLite 实现


此项目包是 R2DBC SPISQLite 实现. 此实现并非旨在直接使用,而是用作 SpringDataR2DBC 等人性化客户端的后端实现.

该驱动实现了以下功能:

  • 文件系统或内存型数据库实例
  • 显示事务
  • 执行参数化的预编译语句
  • 批量执行无参数化的语句
  • 支持大部分数据类型的读写操作,除了LOB类型(像是BLOB,CLOB), BigInteger类型在建表时要特别注意需要使用varchar,TEXT等字符类型代替.
警告 此驱动对于SQLite文件的读写以及SQL语句的执行部分使用SQLITE-JDBC实现. 在使用与构建版本中不相同的SQLite版本时r2dbc-sqlite不保证其兼容性. 因为使用了JDBC以及SQLite是一个文件型数据库,对其进行操作的各个部分都是阻塞的,比如文件访问,所以仅能保证在SQLite的上层中是非阻塞的. 尽管如此,r2dbc-sqlite 也是一个开销比较小的使用r2dbc的选择.

入门


环境要求

  • JDK 21 或更高版本
  • Spring Boot 3.4.4 或更高版本
  • Spring Data R2DBC 3.4.4 或更高版本

示例代码

以下是一个如何在Java中使用R2DBC Sqlite 的示例:

使用URL连接工厂连接内存型数据库

ConnectionFactory connectionFactory = ConnectionFactories.get("r2dbc:sqlite:///:memory:");

Publisher<? extends Connection> connectionPublisher = connectionFactory.create();

使用URL连接工厂连接文件型数据库

ConnectionFactory connectionFactory = ConnectionFactories.get("r2dbc:sqlite:///[my/relative/path]");

Publisher<? extends Connection> connectionPublisher = connectionFactory.create();

使用代码配置连接工厂

ConnectionFactoryOptions options = builder()
        .option(DRIVER, "sqlite")
        .option(DATABASE, "test-database.sqlite")
        .build();
// 上方配置任选其一
ConnectionFactory connectionFactory = ConnectionFactories.get(options);

Publisher<? extends Connection> connectionPublisher = connectionFactory.create();

// 另一个选择: 使用Project Reactor 创建一个Mono
Mono<Connection> connectionMono = Mono.from(connectionFactory.create());

支持的ConnectionFactory发现选项

选项 介绍
driver 必须是 sqlite
database 要使用的数据库.
对于文件型数据库:可以是相对路径或绝对路径
对于内存型数据库是固定值":memory:",引号内部包含冒号
url r2dbc:sqlite:[database file path],方括号部分可以填database选项值

使用代码配置连接

SqliteConnectionFactory connectionFactory = new SqliteConnectionFactory(SqliteConnectionConfiguration.builder()
    .database("foo.db") // database 和 url 二选一
    .url("r2dbc:sqlite:foo.db") // url 优先级高
    .build());

Mono<Connection> connection = connectionFactory.create();

使用代码配置内存连接

SqliteConnectionFactory connectionFactory = new SqliteConnectionFactory(SqliteConnectionConfiguration.builder()
.database(":memory:") // database 和 url 二选一
.url("r2dbc:sqlite::memory:") // url 优先级高
.build());

Mono<Connection> connection = connectionFactory.create();

设置查询参数

根据SQLite 官方语义文档参数章节说明中所写,SQLite参数前缀有5种,这里使用美元符号‘$’.

以下SQL语句使用了参数:

INSERT INTO person (id, first_name, last_name) VALUES ($1, $2, $3)

在绑定参数是使用相同名称,以引用SQL中的参数位置:

connection
    .createStatement("INSERT INTO person (id, first_name, last_name) VALUES ($1, $2, $3)")
    .bind("$1", 1)
    .bind("$2", "Walter")
    .bind("$3", "White")
    .execute();

也支持使用索引绑定参数:

  • 索引 bind(1,"Walter"). 索引从零开始.
  • 可转换为Integer的对象 bind(Integer对象,"Walter"). 在参数索引被框架转换为对象时尤为有用.

一些有用的帮助

在使用R2DBC时,如果遇到问题,可以参考以下资源:

如何提交问题

r2dbc-sqlite使用Gitee作为问题跟踪系统来记录错误和功能请求。如果您想提出问题,请遵循以下建议:

  • 在记录错误之前,请搜索问题跟踪器,查看是否有人已经报告了问题。
  • 如果问题不存在,请创建一个新问题。
  • 请在问题报告中提供尽可能多的信息,我们想知道您使用的R2DBC sqlite版本和JVM版本。
  • 如果你需要粘贴代码或包含堆栈跟踪,请在文本前后使用Markdown转义符。
  • 如果可能的话,尝试创建一个复制该问题的测试用例或项目。为代码或包含代码的压缩文件附加链接。

从源码构建

R2DBC SQLite 二进制包在JitPack.io上发布. 如果您想从源码构建R2DBC SQLite,可以按照以下步骤操作:

  • 克隆项目仓库到本地
  • 使用Maven和Jdk21构建项目
