SpringBoot启动类中添加ComponentScan 19 | ```java 20 | @SpringBootApplication(exclude = DataSourceAutoConfiguration.class) 21 | // 添加这部分 22 | @ComponentScan({"cn.caohd.seata.async.*"}) 23 | public class Application { 24 | public static void main(String[] args) { 25 | SpringApplication.run(Application.class, args); 26 | } 27 | } 28 | ``` 29 | #### 4. 自动注入并且使用 30 | ```java 31 | @Resource SeataAsyncUtil seataAsyncUtil; 32 | 33 | /** 34 | * 调用 times 次 userMapper，每次往数据库插入100条数据 35 | * @param times 调用次数 36 | * @return 插入成功的条数 37 | */ 38 | @GlobalTransactional 39 | public int batchInsert(int times, int size) throws Exception { 40 | // 旧写法 41 | // int counter = 0; 42 | // for (int i = 0; i < times; i++) { 43 | // userMapper.batchInsert(buildRandomUsers(size)); 44 | // } 45 | // return counter; 46 | 47 | // 新写法 48 | int counter = 0; 49 | for (int i = 0; i < times; i++) { 50 | seataAsyncUtil.async(() -> userMapper.batchInsert(buildRandomUsers(size))); 51 | } 52 | // 如果不关心返回值可以不用在这里get 53 | for (SeataAsyncCallInfo callInfo : SeataAysncCallContext.getAsyncInfos()) { 54 | counter += callInfo.get(); 55 | } 56 | 57 | return counter; 58 | } 59 | ``` 60 | 61 | ### 注意事项 62 | 1. 这个依赖只是用来解决部分问题，不是解决全部问题 63 | 2. 这个仅用于TM端，不要用来RM端(其实要实现RM端的话，可以仿照SeataAsyncAspect，写一个aspect，很简单的) 64 | 3. 不要进行事务嵌套，不支持事务嵌套 65 | 4. 确保异步的多个操作之间是没有先后顺序的 66 | 67 | ### 应用场景 68 | 1. 一个全局事务包含多个分支事务 69 | 2. 分支事务之间是没有执行的先后顺序的 70 | 71 | ### 性能测试报告 72 | 使用上面的例子测试，传入的times=50，seata-server的mode=db 73 | 74 | 如果使用同步的方式执行的话，用时约为3s 75 | 76 | 使用异步的方式测试的话，用时约800ms -------------------------------------------------------------------------------- /pom.xml: -------------------------------------------------------------------------------- 1 | 2 | 5 | 4.0.0 6 | 7 | cn.caohd 8 | seata-async 9 | 0.1.0-SNAPSHOT 10 | 11 | 12 | 13 | org.apache.maven.plugins 14 | maven-compiler-plugin 15 | 16 | 8 17 | 8 18 | 19 | 20 | 21 | 22 | 23 | 24 | 25 | io.seata 26 | seata-all 27 | 1.3.0 28 | 29 | 30 | org.springframework.boot 31 | spring-boot-starter 32 | 2.2.0.RELEASE 33 | 34 | 35 | 36 | org.aspectj 37 | aspectjweaver 38 | 1.9.6 39 | runtime 40 | 41 | 42 | org.aspectj 43 | aspectjrt 44 | 1.6.12 45 | 46 | 47 | org.springframework.boot 48 | spring-boot-starter-test 49 | 2.2.0.RELEASE 50 | test 51 | 52 | 53 | -------------------------------------------------------------------------------- /src/main/java/cn/caohd/seata/async/aspect/SeataAsyncAspect.java: -------------------------------------------------------------------------------- 1 | package cn.caohd.seata.async.aspect;
