mongodb副本集与spring的整合
1.先吧mongdb压缩包放到/usr/local 目录下
2.
解压命令
tar zxvf
解压三次
3.
分别在3个mongodb文件夹下创建文件夹mongodata
4.
/usr/local/mongodb1/bin/mongod --dbpath /usr/local/mongodb1/mongodata --port 27017 --replSet repl
/usr/local/mongodb2/bin/mongod --dbpath /usr/local/mongodb2/mongodata --port 27018 --replSet repl
/usr/local/mongodb3/bin/mongod --dbpath /usr/local/mongodb3/mongodata --port 27019 --replSet repl
5.创建副本集，任意启动一个mongodb之后，复制下代码
config = { _id:"repl", members:[{_id:0,host:"192.168.126.153:27017"},{_id:1,host:"192.168.126.153:27018"},
{_id:2,host:"192.168.126.153:27019",arbiterOnly:true}]}

6.初始化
rs.initiate(config)
7
与idea整合
spring项目
1.导jar包
org.springframework.boot
spring-boot-starter-data-mongodb
2.application.yml中配置
# MongoDB URI配置 重要，添加了用户名和密码验证
spring:
data:
mongodb:
uri: mongodb://192.168.126.153:27017,192.168.126.153:27018,192.168.126.153:27019/testu?slaveOk=true&replicaSet=repl&write=1&readPreference=secondaryPreferred&connectTimeoutMS=300000
#每个主机的连接数
connections-per-host: 50
#线程队列数，它以上面connectionsPerHost值相乘的结果就是线程队列最大值
threads-allowed-to-block-for-connection-multiplier: 50
connect-timeout: 5000
socket-timeout: 3000
max-wait-time: 1500
#控制是否在一个连接时，系统会自动重试
auto-connect-retry: true
socket-keep-alive: true
3.在controler中
package com.jk.controller;
import com.jk.model.user;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.mongodb.core.MongoTemplate;
import org.springframework.data.mongodb.core.query.Query;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import java.util.List;
/**
* @author ：mmzs
* @date ：Created in 2019/5/7 21:18
* @description：

*/
@Controller
public class usecontroller {
@Autowired
private MongoTemplate mongoTemplate;
@RequestMapping("finduse")
@ResponseBody
public int finduse() {
List users = mongoTemplate.find(new Query(), user.class);
System.out.println(users);
return 1;
}
@RequestMapping("addUser")
@ResponseBody
public int addUser() {
user user = new user();
user.setId(1);
user.setName("222");
mongoTemplate.save(user);
return 2;
}
}
model层
package com.jk.model;
import java.io.Serializable;
/**
* @author ：mmzs
* @date ：Created in 2019/5/7 21:17
* @description：
* @modified By：
* @version: $
*/
public class user implements Serializable {
private static final long serialVersionUID = 9147550436076328527L;
private Integer id;
private String name;
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
