SpringBoot整合MongoDB

1、下载安装MongoDB

2、初始化配置

假设安装在D:\MongoDB

创建D:\MongoDB\data\db文件夹

创建D:\MongoDB\data\log文件夹

创建D:\MongoDB\mongod.cfg，内容如下（路径自行修改）

systemLog:
    destination: file
    path: D:\MongoDB\data\log\mongod.log
storage:
    dbPath: D:\MongoDB\data\db

3、创建服务

D:\mongodb\bin\mongod.exe --config "D:\mongodb\mongod.cfg" --install

4、启动服务端

D:\MongoDB\bin\mongod --dbpath=..\data\db

5、启动客户端

直接双击D:\MongoDB\bin\mongo.exe

6、SpringBoot整合MongoDB

pom.xml引用依赖

<dependency>
    <groupId>org.springframework.bootgroupId>
    <artifactId>spring-boot-starter-data-mongodbartifactId>
dependency>

application.yml增加配置

spring:
  data:
    mongodb:
      uri: mongodb://localhost/test

测试

package com.hsb.java_demo;
 
import com.hsb.java_demo.domain.Book;
import com.mongodb.client.result.DeleteResult;
import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.data.mongodb.core.MongoTemplate;
 
import java.util.List;
 
@SpringBootTest
public class MongoDBTest {
    @Autowired
    private MongoTemplate mongoTemplate;
 
    @Test
    public void testSave() {
        Book book = new Book();
        book.setId(1);
        book.setName("SpringBoot");
        book.setType("SpringBoot");
        book.setDescription("SpringBoot");
 
        mongoTemplate.save(book);
    }
 
    @Test
    public void testFindAll() {
        List all = mongoTemplate.findAll(Book.class);
        System.out.println(all);
    }
 
    @Test
    public void test() {
        Book book = new Book();
        book.setId(1);
        DeleteResult remove = mongoTemplate.remove(book);
        System.out.println(remove);
 
    }
}
