[ 將mongodb 移動到你想安裝的目錄
[[email protected] opt]# mv mongodb-linux-x86_64-3.2.12 /usr/local/mongodb在mongodb目錄下建立日誌、資料等存放資料夾
[[email protected] mongodb]# cd /usr/local/mongodb/
[[email protected] mongodb]# mkdir data/db
[[email protected] 建立配置檔案
[[email protected] mongodb]# cd bin/
[[email protected] bin]# vim mongodb.yml
mongodb.yml
#日誌檔案存放地址配置 systemLog: destination: file path: "/usr/local/mongodb/logs/mongodb.log" logAppend: true #資料存放地址配置 storage: dbPath: "/usr/local/mongodb/data/db" journal: enabled: true #守護程序執行 processManagement: fork: true #ip埠繫結 net: bindIp: 192.168.126.130 port: 27017
需要注意的是 請給data\db logs等資料夾相關許可權否則啟動會報錯。
啟動mongodb
[[email protected] mongodb]# cd bin/
[[email protected] bin]# vim mongodb.yml
[[email protected] bin]# ls
bsondump mongo mongod mongodb.yml mongodump mongoexport mongofiles mongoimport mongooplog mongoperf mongorestore mongos mongostat mongotop
[[email protected] bin]# ./mongod --config mongodb.yml
通過客戶端直接操作mongo
[[email protected] bin]# ls
bsondump mongo mongod mongodb.yml mongodump mongoexport mongofiles mongoimport mongooplog mongoperf mongorestore mongos mongostat mongotop
[[email protected] bin]# ./mongo 192.168.126.130:27017/test

建立mongo資料操作類、介面 這裡有兩種實現方式 使用MongoRepository 和MongoTemplate
繼承MongoRepository：
@Component
public interface UserRepository extends MongoRepository<UserPo, Long> {
/*
* MongoRepository與HibernateTemplete相似，提供一些基本的方法，
* 實現的方法有findone(),save(),count(),findAll(),findAll(Pageable),delete(),deleteAll
* ()..etc 要使用Repository的功能，先繼承MongoRepository<T, TD>介面
* 其中T為倉庫儲存的bean類，TD為該bean的唯一標識的型別，一般為ObjectId。
* 之後在spring-boot中注入該介面就可以使用，無需實現裡面的方法，spring會根據定義的規則自動生成。 starter-data-mongodb
* 支援方法命名約定查詢 findBy{User的name屬性名}， findBy後面的屬性名一定要在User類中存在，否則會報錯
*/
/**
* 通過手機號查詢
*
* @param phone
* @return
*/
public List<UserPo> findByPhone(String phone);
}
使用MongoTemplate
package com.cloud.mongodb.mongo.dao;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.mongodb.core.MongoTemplate;
import org.springframework.stereotype.Component;
import com.cloud.mongodb.po.UserPo;
@Component
public class UserDao {
@Autowired
private MongoTemplate mongoTemplate;
public void save(UserPo user) {
mongoTemplate.save(user);
}
}
兩種方式的優缺點：
MongoRepository：
它其實就是繼承Repository 的子介面 ，Repository 是 Spring Data 的一個核心介面。使用它可以使你不用寫相關的查詢組合語句，它會內部為我們實現這樣的一個類。只要你按規定定義好介面名就可以免去你寫查詢組合語句。相關詳細介紹的部落格地址：https://blog.csdn.net/qinsihang/article/details/19921981
MongoTemplate：
MongoTemplate是資料庫和程式碼之間的介面，它有兩個核心的類：Criteria類：封裝所有的語句，以方法的形式查詢、Query類：將語句進行封裝或者新增排序之類的操作。
MongoRepository的缺點是不夠靈活，MongoTemplate 正好可以彌補
執行測試：
package com.cloud.mongodb;
import java.util.List;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;
import com.cloud.mongodb.mongo.dao.UserDao;
import com.cloud.mongodb.mongo.repository.UserRepository;
import com.cloud.mongodb.po.UserPo;
@SpringBootTest
@RunWith(SpringRunner.class)
public class AppTest {
@Autowired
private UserDao dao;
@Autowired
private UserRepository repository;
@Test
public void test1() {
UserPo user = new UserPo();
user.setUserId(2L);
user.setUserName("張三");
user.setUserNickName("老張");
user.setUserAge(33);
user.setPhone("13323333233");
user.setUserSex(1);
user.setEmail("[email protected]");
dao.save(user);
}
@Test
public void test2() {
List<UserPo> list = repository.findByPhone("13323333233");
if (null != list && !list.isEmpty()) {
for (UserPo userPo : list) {
System.out.println(userPo.toString());
}
}
}
}
