简介

github地址

spring-boot-starter-seata：https://github.com/itrickzhang/spring-boot-starter-seata

seata版本

server和client版本为0.4.1，Seata 一直在快速迭代在1.0 之前都有可能出现协议不兼容尽量使用版本号一致

说明

目前提供的示例是针对使用dubbo的服务，那Spring Boot的项目如何集成fescar呢？

快速开始

使用案例

Business Service购买商品的业务逻辑。整个业务逻辑由3个微服务驱动:

Storage service: 扣除给定商品的库存量.
Order service: 根据采购需求创建订单.
Account service: 借记用户帐户上的余额.

请求逻辑

业务脚本


    
    
     
     DROP TABLE IF EXISTS `storage_tbl`;
     
     CREATE TABLE `storage_tbl` (
     
      `id` int(11) NOT NULL AUTO_INCREMENT,
     
      `commodity_code` varchar(255) DEFAULT NULL,
     
      `count` int(11) DEFAULT 0,
     
      PRIMARY KEY (`id`),
     
      UNIQUE KEY (`commodity_code`)
     
     ) ENGINE=InnoDB DEFAULT CHARSET=utf8;

      `money` int(11) DEFAULT 0,
     
      PRIMARY KEY (`id`)
     
     ) ENGINE=InnoDB DEFAULT CHARSET=utf8;

事务脚本


    
    
     
     -- 注意此处0.3.0+ 增加唯一索引 ux_undo_log
     
     CREATE TABLE `undo_log` (
     
      `id` bigint(20) NOT NULL AUTO_INCREMENT,
     
      `branch_id` bigint(20) NOT NULL,

集成


    
    
     
     <dependency>
     
      <groupId>org.springframework.boot</groupId>
     
      <artifactId>spring-boot-starter-seata</artifactId>
     
      <version>${project.version}</version>
     
     </dependency>

使用

使用注解@GlobalTransactional


    
    
     
      @GlobalTransactional(timeoutMills = 300000, name = "spring-cloud-demo-tx")
     
      @RequestMapping(value = "/fescar/feign", method = RequestMethod.GET, produces = "application/json")
     
      public String feign() {
     
      LOGGER.info("business Service Begin ... xid: " + RootContext.getXID());
     
      String result = storageService.storage(COMMODITY_CODE, ORDER_COUNT);
     
      if (!SUCCESS.equals(result)) {
     
      throw new RuntimeException();
     
      }
     
      result = orderService.order(USER_ID, COMMODITY_CODE, ORDER_COUNT);
     
      if (!SUCCESS.equals(result)) {
     
      throw new RuntimeException();
     
      }
     
      return SUCCESS;
     
      }
