4 | 在单机数据库下很容易维持事务的 ACID特性，但在分布式系统中并不容易，DTS可以保证分布式系统中的分布式事务的 ACID 特性 5 | 6 | # 功能 7 | * 跨消息和数据库的分布式事务
8 | 在某些业务场景中，需要进行多个 DB 操作的同时，还会调用消息系统，DB 操作成功、消息发送失败或者反过来都会造成业务的不完整 9 | * 跨服务的分布式事务
10 | 业务完成服务化后，资源与客户端调用解耦，同时又要保证多个服务调用间资源的变化保持强一致，否则会造成业务数据的不完整,DTS支持跨服务的事务 11 | 12 | # 详细说明 13 | 14 | * Dts Server：事务协调器。负责分布式事务的推进，管理事务生命周期 15 | * Dts Client：事务发起者。通过事务协调器，开启、提交、回滚分布式事务 16 | * Dts Resource：资源，包括数据库、MQ 17 | 18 | # 架构方案 19 | * 请查看根目录下的架构图 20 | 21 |  ![架构图](architecture.png) 22 | 23 | * 流程图 24 |  ![流程图](flow.png) 25 | 26 | # Compile 27 | ``` 28 | mvn install -Dmaven.test.skip=true 29 | ``` 30 | # 关于Sample 31 |  详细请查看 sample 32 | 33 | # Quick Start 34 | * 客户端及资源端添加pom依赖 35 | 36 | ``` 37 | 38 | io.dts 39 | dts-saluki-support 40 | ${dts.version} 41 | 42 | ``` 43 | 44 | * 在Dts客户端、Dts资源端、Dts服务端的启动参数加上-DZK_CONNECTION=127.0.0.1:2181，zookeeper的连接地址，Dts使用zookeeper来做集群管理 45 | 46 | * 客户端，在服务调用不同的接口添加@DtsTransaction注解，将两个服务调用纳入整个分布式事务管理 47 | 48 | 49 | ``` 50 | @DtsTransaction 51 | public HelloReply callService() { 52 | HelloRequest request = new HelloRequest(); 53 | request.setName("liushiming"); 54 | HelloReply reply = helloService.dtsNormal(request); 55 | helloService.dtsException(request); 56 | return reply; 57 | } 58 | 59 | ``` 60 | * 资源端，针对数据库资源，使用Dts的适配DtsDataSource来使数据库连接池转变为Dts资源 61 | 62 | 1. 执行script/resource.sql脚本 63 | 2. 将数据库连接池适配为Dts资源端 ,如下示例： 64 | 65 | ``` 66 | @Bean 67 | @Primary 68 | public DataSource dataSource() { 69 | DruidDataSource datasource = new DruidDataSource(); 70 | int startIndex = dbUrl.lastIndexOf("/"); 71 | String databaseName = dbUrl.substring(startIndex + 1, dbUrl.length()); 72 | datasource.setConnectionProperties(connectionProperties); 73 | return new DtsDataSource(datasource, databaseName); 74 | } 75 | 76 | ``` 77 | 78 | * 服务端，针对spring boot直接启动Main，将事务协调器启动起来 79 | 80 | 1. 执行script/server.sql脚本 81 | 2. 启动事务协调器服务端 82 | 83 | 84 | -------------------------------------------------------------------------------- /dts-microservice-support/dts-saluki-support/src/main/java/io/dts/saluki/SalukiContext.java: -------------------------------------------------------------------------------- 1 | /* 2 | * Copyright 2014-2017 the original author or authors. 3 | * 4 | * Licensed under the Apache License, Version 2.0 (the "License"); you may not use this file except 5 | * in compliance with the License.
