mongoDB 事务(springboot)

原文:https://www.cnblogs.com/vettel0329/p/10778931.html

依赖:

<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-mongodb</artifactId>
 </dependency>

创建配置类，开启事务

@Configuration
public class TransactionConfig {

    @Bean
    MongoTransactionManager transactionManager(MongoDbFactory factory){
        return new MongoTransactionManager(factory);
    }

}

开启事务:

@Service
public class UserService {

    @Resource
    MongoTemplate mongotemplate;

    public List<User> getAllUser(){
        return mongotemplate.findAll(User.class);
    }

    @Transactional
    public boolean addUser(User user, UserInfo userInfo){
        user.setUserInfo(userInfo);
        mongotemplate.save(userInfo);
//        int a = 1/0;    //事务测试代码
        mongotemplate.save(user);
        return true;
    }

}

注：以上为MongoTemplate方式，MongoTemplate和MongoRepository方式都与Spring整合SpringDataMongoDB相同
