1：如何在外网环境下开放mongodb
服务器版本：centos7.6
(1) 保证mongodb的启动配置文件中使用了bind_ip=0.0.0.0
(2) 保证服务器开放了27017端口
(3) 保证云服务器的安全组中开放了27017
可参考我之前的博客：https://www.cnblogs.com/zgq7/p/11564860.html
自述：昨天我在学习的时候使用mongodb桌面根据robo 3T连接我的外网mongodb时可以稳定快速的连接，
但是在我的SpringBoot项目中却一直连接超时，经过重复的实验及思考后分析出了问题所在：
1：我的robo 3T 采用的是SSH连接，让我一直以为mongodb处于外网开放状态
2：我的云服务器没有开放27017端口
3：我的安全组也没有开放27017端口
彻底开放之后可以在服务器上做一下测试：
如出现上图则表示mongodb外网彻底放通了。
2：如何在SpringBoot中整合
我的版本：SpringBoot2.1.7+Java8+Mongodb 4.0
(1): springboot中的依赖
1 <dependencies> 2 <dependency> 3 <groupId>org.springframework.boot</groupId> 4 <artifactId>spring-boot-starter</artifactId> 5 </dependency> 6 7 <dependency> 8 <groupId>org.springframework.boot</groupId> 9 <artifactId>spring-boot-starter-web</artifactId> 10 </dependency> 11 12 <dependency> 13 <groupId>org.springframework.boot</groupId> 14 <artifactId>spring-boot-starter-data-mongodb</artifactId> 15 </dependency> 16 17 <dependency> 18 <groupId>org.springframework.boot</groupId> 19 <artifactId>spring-boot-starter-test</artifactId> 20 <scope>test</scope> 21 </dependency> 22 23 </dependencies>View Code
(2): model
package com.boot.mongodb.model;
import org.springframework.data.annotation.Id;
import org.springframework.data.mongodb.core.mapping.Document;
@Document(collection = "test")
public class UserModel {
@Id
private Object id;
private String name;
private Integer age;
private String from;
public UserModel() {
}
public UserModel(String name, Integer age) {
this.name = name;
this.age = age;
}
public UserModel(Object id, String name, String from) {
this.id = id;
this.name = name;
this.from = from;
}
public UserModel(Integer id, String name, Integer age) {
this.id = id;
this.name = name;
this.age = age;
}
public UserModel(Object id, String name, Integer age, String from) {
this.id = id;
this.name = name;
this.age = age;
this.from = from;
}
public Object getId() {
return id;
}
public void setId(Object id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public Integer getAge() {
return age;
}
public void setAge(Integer age) {
this.age = age;
}
@Override
public String toString() {
return "UserModel{" +
"id=" + id +
", name='" + name + '\'' +
", age=" + age +
", from='" + from + '\'' +
'}';
}
}
1:@Document(collection = "test") 代表该实体映射到该库的test集合
2:@ID 指该字段映射到test集合的ID
(3): 作为持久化有两种方式：
1：使用Repostory的方式
package com.boot.mongodb.repository;
import com.boot.mongodb.model.UserModel;
import org.springframework.data.mongodb.repository.MongoRepository;
import org.springframework.stereotype.Repository;
@Repository
public interface UserRepository extends MongoRepository<UserModel, Integer> {
}
增删改查：
//==============================基于Repository的增删改查
@Test
public void add() {
UserModel userModel = new UserModel(1, "lzq", 23, "Repository");
System.out.println(userRepository.insert(userModel));
}
@Test
public void remove() {
UserModel userModel = new UserModel(1, "lzq", 23, "Repository");
userRepository.delete(userModel);
}
@Test
public void update() {
UserModel userModel = new UserModel(2, "lzq", 24, "Repository");
//有则修改，无则新增
System.out.println(userRepository.save(userModel));
}
@Test
public void find() {
System.out.println(userRepository.findAll());
UserModel userModel = new UserModel(2, "lzq", 24, "Repository");
Example example = Example.of(userModel);
System.out.println(userRepository.findOne(example));
System.out.println(userRepository.findAll(example));
}
2：使用MongoTemplate的方式,不用创建对应的Repostroy
增删改查
//===============================基于MongoTemplate的增删改查
@Test
public void tadd() {
UserModel userModel = new UserModel(3, "lzq", 24, "MongoTemplate");
logger.info("{}", mongoTemplate.insert(userModel));
}
@Test
public void tdelete() {
//UserModel userModel = new UserModel(3, "lzq", 24, "MongoTemplate");
//输出删除的行数
//System.out.println(mongoTemplate.remove(userModel).getDeletedCount());
Query query = new Query(Criteria.where("id").is(3));
logger.info("{}", mongoTemplate.remove(query, UserModel.class).getDeletedCount());
}
@Test
public void tupdate() {
Query query = new Query(Criteria.where("id").is(3));
Update update = new Update().set("name", "2333333");
logger.info("{}", mongoTemplate.updateFirst(query, update, UserModel.class));
}
@Test
public void tfind() {
Query query = new Query(Criteria.where("id").is(3));
logger.info("{}", mongoTemplate.find(query, UserModel.class));
}
