安装测试 MongoDB

拉取镜像

docker pull mongo:latest

创建和启动容器

docker run -d --restart=always -p 27017:27017 --name mymongo -v /data/db:/data/db -d mongo

登录mongo容器，并进入到【admin】数据库

MongoDB 6.0 及以上版本进入容器使用如下命令

docker exec -it mymongo[创建时对应的MongoDB容器名] mongosh admin

创建一个用户，mongo 默认没有用户

db.createUser({ user:'root',pwd:'123456',roles:[ { role:'userAdminAnyDatabase', db: 'admin'},'readWriteAnyDatabase']});

【user:‘root’ 】：设置用户名为root
【pwd:‘123456’】：设置密码为123456
【role:‘userAdminAnyDatabase’】：只在admin数据库中可用，赋予用户所有数据库的userAdmin权限
【db: ‘admin’】：可操作的数据库
【‘readWriteAnyDatabase’】：赋予用户读写权限

连接mongo数据库

db.auth('root', '123456')

测试数据库，插入一条语句

 db.user.insert({"name":"金智秀","age":18})

测试数据库，查询刚才插入的语句

查看所有数据库

show dbs

开放指定端口

firewall-cmd --add-port=27017/tcp --permanent
firewall-cmd --reload

开放服务器安全组

navicat连接测试

SpringBoot整合mongoDB

导入依赖

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

添加yml配置

spring:data:mongodb:uri: mongodb://192.168.239.140:27017/testusername: rootpassword: 123456

编写实体类

@Data
@Document("User")
public class User {@Idprivate String id;private String name;private Integer age;private String email;private String createDate;
}

测试类

 @Autowiredprivate MongoTemplate mongoTemplate;//添加@Testpublic void createUser() {User user = new User();user.setAge(20);user.setName("金智秀");user.setEmail("4932200@qq.com");User user1 = mongoTemplate.insert(user);System.out.println(user1);}//查询所有@Testpublic void findUser() {List<User> userList = mongoTemplate.findAll(User.class);System.out.println(userList);}//根据id查询@Testpublic void getById() {User user =mongoTemplate.findById("64846c08a263b2302594b596", User.class);System.out.println(user);}//条件查询@Testpublic void findUserList() {Query query = new Query(Criteria.where("name").is("test").and("age").is(20));List<User> userList = mongoTemplate.find(query, User.class);System.out.println(userList);}//模糊查询@Testpublic void findUsersLikeName() {String name = "est";String regex = String.format("%s%s%s", "^.*", name, ".*$");Pattern pattern = Pattern.compile(regex, Pattern.CASE_INSENSITIVE);Query query = new Query(Criteria.where("name").regex(pattern));List<User> userList = mongoTemplate.find(query, User.class);System.out.println(userList);}//分页查询@Testpublic void findUsersPage() {String name = "est";int pageNo = 1;int pageSize = 10;Query query = new Query();String regex = String.format("%s%s%s", "^.*", name, ".*$");Pattern pattern = Pattern.compile(regex, Pattern.CASE_INSENSITIVE);query.addCriteria(Criteria.where("name").regex(pattern));int totalCount = (int) mongoTemplate.count(query, User.class);List<User> userList = mongoTemplate.find(query.skip((pageNo - 1) * pageSize).limit(pageSize), User.class);Map<String, Object> pageMap = new HashMap<>();pageMap.put("list", userList);pageMap.put("totalCount",totalCount);System.out.println(pageMap);}//修改@Testpublic void updateUser() {User user = mongoTemplate.findById("64846c08a263b2302594b596", User.class);user.setName("test_1");user.setAge(25);user.setEmail("493220990@qq.com");Query query = new Query(Criteria.where("_id").is(user.getId()));Update update = new Update();update.set("name", user.getName());update.set("age", user.getAge());update.set("email", user.getEmail());UpdateResult result = mongoTemplate.upsert(query, update, User.class);long count = result.getModifiedCount();System.out.println(count);}//删除操作@Testpublic void delete() {Query query =new Query(Criteria.where("_id").is("64846c08a263b2302594b596"));DeleteResult result = mongoTemplate.remove(query, User.class);long count = result.getDeletedCount();System.out.println(count);}
