Reactive Transaction On Spring D

MongoDB 从 4.0 版开始支持多文档 ACID 事务，Spring Data 则从 Lovelace 版开始支持原生 MongoDB 事务。

Maven 配置：

<dependency>
  <groupId>org.mongodb</groupId>
  <artifactId>mongodb-driver-reactivestreams</artifactId>
  <version>1.9.2</version>
</dependency>
<dependency>
  <groupId>io.projectreactor</groupId>
  <artifactId>reactor-test</artifactId>
  <version>3.2.0.RELEASE</version>
  <scope>test</scope>
</dependency>

使用 ReactiveMongoOperations.inTransaction() :

@Autowired
private ReactiveMongoOperations reactiveOps;
 
@Test
public void test() {
  User user1 = new User("Jane", 23);
  User user2 = new User("John", 34);
  reactiveOps.inTransaction()
    .execute(action -> action.insert(user1)
    .then(action.insert(user2)));
}
