安裝出現 2502、2503 錯誤解決辦法：

啓動命令：mongod.exe --dbpath d:\roncoo_mongodb\
指定路徑：--dbpath
注：要先創建文件夾
一、 添加依賴
<!-- mongodb -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-mongodb</artifactId>
</dependency>
二、 配置文件：
# MONGODB (MongoProperties)
spring.data.mongodb.uri=mongodb://localhost/test
spring.data.mongodb.port=27017
#spring.data.mongodb.authentication-database=
#spring.data.mongodb.database=test
#spring.data.mongodb.field-naming-strategy=
#spring.data.mongodb.grid-fs-database=
#spring.data.mongodb.host=localhost
#spring.data.mongodb.password=
#spring.data.mongodb.repositories.enabled=true
#spring.data.mongodb.username=
三、 代碼
/**
* @author wujing
*/
@Component
public class RoncooMongodbComponent {
@Autowired
private MongoTemplate mongoTemplate;
public void insert(RoncooUser roncooUser) {
mongoTemplate.insert(roncooUser);
}
public void deleteById(int id) {
Criteria criteria = Criteria.where("id").in(id);
Query query = new Query(criteria);
mongoTemplate.remove(query, RoncooUser.class);
}
public void updateById(RoncooUser roncooUser) {
Criteria criteria = Criteria.where("id").in(roncooUser.getId());
Query query = new Query(criteria);
Update update = new Update();
update.set("name", roncooUser.getName());
update.set("createTime", roncooUser.getCreateTime());
mongoTemplate.updateMulti(query, update, RoncooUser.class);
}
public RoncooUser selectById(int id) {
Criteria criteria = Criteria.where("id").in(id);
Query query = new Query(criteria);
return mongoTemplate.findOne(query, RoncooUser.class);
}
}
設置日誌打印：
<logger name="org.springframework.data.mongodb.core.MongoTemplate" level="debug"/>
@Autowired
private RoncooMongodbComponent roncooMongodbComponent;
@Test
public void set() {
RoncooUser roncooUser = new RoncooUser();
roncooUser.setId(1);
roncooUser.setName("無境1");
roncooUser.setCreateTime(new Date());
roncooMongodbComponent.insert(roncooUser);
}
@Test
public void select() {
System.out.println(roncooMongodbComponent.selectById(1));
}
@Test
public void update() {
RoncooUser roncooUser = new RoncooUser();
roncooUser.setId(1);
roncooUser.setName("測試修改");
roncooUser.setCreateTime(new Date());
roncooMongodbComponent.updateById(roncooUser);
System.out.println(roncooMongodbComponent.selectById(1));
}
@Test
public void delete() {
roncooMongodbComponent.deleteById(1);
}
四、使用：MongoRepository
import org.springframework.data.domain.Page;
import org.springframework.data.domain.Pageable;
import org.springframework.data.mongodb.repository.MongoRepository;
import com.roncoo.example.bean.RoncooUserLog;
public interface RoncooUserLogMongoDao extends MongoRepository<RoncooUserLog, Integer>{
RoncooUserLog findByUserName(String string);
RoncooUserLog findByUserNameAndUserIp(String string, String ip);
Page<RoncooUserLog> findByUserName(String string, Pageable pageable);
}
測試
@Autowired
private RoncooUserLogMongoDao roncooUserLogMongoDao;
@Test
public void insert() {
RoncooUserLog entity = new RoncooUserLog();
entity.setId(1);
entity.setUserName("無境");
entity.setUserIp("192.168.0.1");
entity.setCreateTime(new Date());roncooUserLogMongoDao.save(entity);
}
@Test
public void delete() {
roncooUserLogMongoDao.delete(1);
}
@Test
public void update() {
RoncooUserLog entity = new RoncooUserLog();
entity.setId(1);
entity.setUserName("無境2");
entity.setUserIp("192.168.0.1");
entity.setCreateTime(new Date());
roncooUserLogMongoDao.save(entity);
}
@Test
public void select() {
RoncooUserLog result = roncooUserLogMongoDao.findOne(1);
System.out.println(result);
}
@Test
public void select2() {
RoncooUserLog result = roncooUserLogMongoDao.findByUserName("
無境2");
System.out.println(result);
}
// 分頁
@Test
public void queryForPage() {
Pageable pageable = new PageRequest(0, 20, new Sort(new
Order(Direction.DESC, "id")));
// Page<RoncooUserLog> result =
roncooUserLogDao.findByUserName("無境2", pageable);
Page<RoncooUserLog> result =
roncooUserLogMongoDao.findAll(pageable);
System.out.println(result.getContent());
}
五、 使用嵌入式的 mongo
<dependency>
<groupId>de.flapdoodle.embed</groupId>
<artifactId>de.flapdoodle.embed.mongo</artifactId>
</dependency>
注意：
1.加入嵌入式的 mongo 之後，首次啓動會進行下載，時間會比較久，請耐心等待
2.下載完成，啓動之後，默認情況下數據會在內存裏面，重啓會丟失
