SpringDataMongoDB多文档事务的实现

SpringDataMongoDB多文档事务的实现

一、安装MongoDB4.0.3（）

1.1、官方安装文档

https://docs.mongodb.com/manual/tutorial/install-mongodb-on-red-hat/

1.2、tar.gz包下载地址

https://mongodb.com/download-center/community?jmp=docs

1.3、复制集官方配置

https://docs.mongodb.com/manual/administration/replica-set-member-configuration/

二、SpringProject版本依赖（）

Spring：5.1.1.RELEASE 以上

SpringDataMongoDB:2.1.1.RELEASE 以上

三、配置MongoTransactionManager（SpringBoot使用方式）

SpringBoot 集成非常简单，配置MongoTransastionManager，目前Spring-boot-starter-data-mongodb 版本较低不支持，因此暂未验证，SpringBoot配置复制集参考SpringBoot相关文档

@Configuration

static class Config extends AbstractMongoConfiguration {

@Bean

MongoTransactionManager transactionManager(MongoDbFactory dbFactory) {

return new MongoTransactionManager(dbFactory);

}

// ...

}

四、配置MongoTransactionManager（普通Spring项目）

file-encoding="utf-8" />

write-concern="SAFE"

read-preference="NEAREST"

threads-allowed-to-block-for-connection-multiplier="${mongo.threadsAllowedToBlockForConnectionMultiplier}"

connect-timeout="${mongo.connectTimeout}" max-wait-time="${mongo.maxWaitTime}"

socket-keep-alive="${mongo.socketKeepAlive}" socket-timeout="${mongo.socketTimeout}"

max-connection-idle-time="${mongo.maxConnectionIdleTime}"

max-connection-life-time="${mongo.maxConnectionLifeTime}"

heartbeat-socket-timeout="${mongo.heartbeatSocketTimeout}"

heartbeat-connect-timeout="${mongo.heartbeatConnectTimeout}"

min-heartbeat-frequency="${mongo.minHeartbeatFrequency}"

heartbeat-frequency="${mongo.heartbeatFrequency}" />

mongo-ref="mongoClient" />

class="org.springframework.data.mongodb.core.mapping.MongoMappingContext" />

class="org.springframework.data.mongodb.core.convert.DefaultMongoTypeMapper">

class="org.springframework.data.mongodb.core.convert.MappingMongoConverter">

五、使用事务（）

@Service

public class StateService {

@Autowired

private MongoTemplate teplate;

@Transactional

void someBusinessFunction(Step step) {

template.insert(step);

log.debug(1/0);

};

});

六、Mongo.properties 配置

mongo.host=192.168.1.66

mongo.port=27017

mongo.replSet=192.168.1.66:2000,192.168.1.66:2001,192.168.1.66:2002

mongo.minConnectionsPerHost=10

mongo.threadsAllowedToBlockForConnectionMultiplier=4

mongo.connectTimeout=30000

mongo.maxWaitTime=3000

mongo.socketKeepAlive=false

mongo.socketTimeout=30000

mongo.maxConnectionIdleTime=0

mongo.maxConnectionLifeTime=0

mongo.heartbeatSocketTimeout=20000

mongo.heartbeatConnectTimeout=10000

mongo.minHeartbeatFrequency=3000

mongo.heartbeatFrequency=5000

mongo.database=labsta

七、最后是重点（）

7.1、必须使用复制集，单节点不支持，mongodb4.2 会支持分片集事务，复制集安装请自行研究

7.2、使用事务之前（@Transaction），数据库和文档必须提前创建，如何解决呢？且看下篇

7.3、Spring版本和SpringDataMongodb版本必须遵循 @SpringProject版本依赖

7.4、注意，此处的复制集不是4.0版本之前的主从复制集群，4.0之后已废弃主从模式

file-encoding="utf-8" />

write-concern="SAFE"

read-preference="NEAREST"

threads-allowed-to-block-for-connection-multiplier="${mongo.threadsAllowedToBlockForConnectionMultiplier}"

五、使用事务（）

@Service

public class StateService {

@Autowired

private MongoTemplate teplate;

@Transactional

void someBusinessFunction(Step step) {

template.insert(step);

log.debug(1/0);

};

});

六、Mongo.properties 配置

mongo.replSet=192.168.1.66:2000,192.168.1.66:2001,192.168.1.66:2002

mongo.socketTimeout=30000
