一、mongodb介绍
MongoDB 是一个介于关系数据库和非关系数据库之间的产品，是非关系数据库当中功能最丰富，且与关系数据库的最为相像的。它支持的数据结构非常松散，是类似 json 的 bson 格式，因此可以存储比较复杂的数据类型。Mongo 最大的特点是它支持的查询语言非常强大，其语法有点类似于面向对象的查询语言，几乎可以实现类似关系数据库单表查询的绝大部分功能，而且还支持对数据建立索引。
二、mongodb环境搭建
采用docker-compose搭建，配置文件如下
version: '3'
# 网桥mongo -> 方便相互通讯
networks:
mongo:
services:
# mongodb
mongodb:
image: registry.cn-hangzhou.aliyuncs.com/zhengqing/mongo:4.4.6 # 原镜像`mongo:4.4.6`
restart: unless-stopped
container_name: mongodb
environment:
MONGO_INITDB_ROOT_USERNAME: admin
MONGO_INITDB_ROOT_PASSWORD: 123456
MONGO_DATA_DIR: /data/db
MONGO_LOG_DIR: /data/logs
# volumes:
# - ./mongodb/db:/data/db
# - ./mongodb/log:/data/log
ports:
- "27017:27017"
networks:
- mongo
# 可视化图形工具
adminmongo:
image: mrvautin/adminmongo
restart: unless-stopped
container_name: adminmongo
environment:
- HOST=0.0.0.0
depends_on:
- 'mongodb'
links:
- mongodb
ports:
- "1234:1234"
networks:
- mongo
启动代码
docker-compose -f docker-compose-mongodb.yml -p mongodb up -d
访问地址：[`http://ip地址:1234\`\](http://127.0.0.1:1234)
Connection string：`mongodb://admin:123456@ip地址:27017`

测试类
package com.et.mongodb;
import com.et.mongodb.entity.Status;
import com.et.mongodb.entity.User;
import com.mongodb.client.model.Indexes;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.data.mongodb.core.MongoTemplate;
import org.springframework.test.context.junit4.SpringRunner;
import javax.annotation.Resource;
import java.util.Date;
@RunWith(SpringRunner.class)
@SpringBootTest(classes = DemoApplication.class)
public class MongodbTests {
private Logger log = LoggerFactory.getLogger(getClass());
private static final String COLLECTION_NAME = "users";
@Resource
private MongoTemplate mongoTemplate;
@Test
public void createIndex() {
String field = "name";
// create index
mongoTemplate.getCollection(COLLECTION_NAME).createIndex(Indexes.ascending(field));
}
@Test
public void insert() {
// set user info
User user = new User()
.setId("10")
.setAge(22)
.setSex("man")
.setRemake("nothing")
.setSalary(1500)
.setName("zhangsan")
.setBirthday(new Date())
.setStatus(new Status().setHeight(180).setWeight(150));
// insert user info,throw exception when the row record is exist
User newUser = mongoTemplate.insert(user, COLLECTION_NAME);
// output result
log.info("user info：{}", newUser);
}
}
