Spring 集成mongodb

简述：项目采用spring-maven 集成mongodb

pom.xml中引入对应maven包依赖

	        <dependency>
			<groupId>org.mongodb</groupId>
			<artifactId>mongo-java-driver</artifactId>
			<version>2.13.0-rc0</version>
		</dependency>

3.mongo.properties配置文件

mongo.host=xxx.xxx.xxx.xxx
mongo.port=27017
mongo.user=zhangsan
mongo.pwd=123456
mongo.connectionsPerHost=8
mongo.threadsAllowedToBlockForConnectionMultiplier=4
mongo.connectTimeout=1000
mongo.maxWaitTime=1500
mongo.autoConnectRetry=true
mongo.socketKeepAlive=true
mongo.socketTimeout=1500
mongo.slaveOk=true
mongo.writeNumber=1
mongo.riteTimeout=0
mongo.writeFsync=true

linux centos7 安装mongodb 官网下载 mongodb-linux-x86_64-rhel70-3.6.3.tgz，上传到服务器/usr/local文件夹下
tar -zxvf mongodb-linux-x86_64-rhel70-3.6.3.tgz 解压到当前文件夹下修改文件夹名称为mongodb3.6.3，进入到当前文件夹下 cd mongodb3.6.3
mkdir logs / mkdir data 创建文件文件夹和日志文件夹
新建mongodb.conf 文件，内容如下放置到bin 文件夹下

# data-path
dbpath=/usr/local/mongodb3.6.3/data/

# log-path
logpath=/usr/local/mongodb3.6.3/logs/mongodb.log

# port
port=27017

# work-type:
fork=true

#bind-ip
bind_ip=0.0.0.0

#auth
#auth=true

启动mongodb命令：./mongod --config mongodb.conf
关闭命令：连接mongodb后 use admin 之后输入db.shutdownServer() 或者 kill -9 进程号强制关闭
默认是用户验证是关闭的，当auth=true开启后，需要增加用户账号密码
设置用户账号密码设置root用户连接mongodb后 use admin

userAdminAnyDatabase 这个角色拥有分配角色和用户的权限，但没有查写的缺陷
root  这是超级管理员
readWrite  有读写权限
read    有读权限

db.createUser({user:"root",pwd:"123456",roles:[{"role":"root","db":"admin"}]})

为其他库建立用户
use otherDB

db.createUser({user:"zhangsan",pwd:"123456",roles:[{"role":"readWrite","db":"otherDB"}]})

设置好发现，连接工具可以连接上，但是程序连接不上报错

org.springframework.data.mongodb.CannotGetMongoDbConnectionException: Failed to authenticate to database [otherDB], username = [zhangsan], password = [1****6]

解决方法在网上看到一个帖子：mongodb3.03以上开启认证,解决程序认证连接报错以及第三方客户端无法认证问题

常用命令

.查看加密方式
db.system.version.findOne({"_id" : "authSchema"})
5:SCRAM－SHA－1
3:MONGODB－CR

删除用户
db.dropUser("myuser")
