Springboot之整合MongoDB

Springboot之整合MongoDB

一、在虚拟机中安装MongoDB

执行脚本

#！/bin/bash
echo "**************************************"
echo "*****                            *****"
echo "***       Mongodb 安装             ***"
echo "*****                            *****"
echo "**************************************"

echo "=====>开始下载Mongodb:"
wget https://fastdl.mongodb.org/linux/mongodb-linux-x86_64-3.6.3.tgz
if [ $? -eq 0 ]; then
    echo "=====>下载成功！"
    echo "=====>开始解压！"
    tar -zxvf mongodb-linux-x86_64-3.6.3.tgz
    echo "=====>解压成功！"
    mkdir /usr/local/mongodb &&  mv mongodb-linux-x86_64-3.6.3/* /usr/local/mongodb/ && cd /usr/local/mongodb && mkdir data && touch logs && cd bin
    echo "=====>开始安装!"
    ./mongod --dbpath=/usr/local/mongodb/data --logpath=/usr/local/mongodb/logs --logappend  --port=27017 --fork
    if [ $? -eq 0 ]; then
        echo "=====>安装成功";
        touch mongodb.conf
        echo "=====>配置mongodb"
        echo "dbpath=/usr/local/mongodb/data" >> mongodb.conf
        echo "logpath=/usr/local/mongodb/logs" >> mongodb.conf
        echo "logappend=true" >> mongodb.conf
        echo "port=27017" >> mongodb.conf
        echo "fork=true" >> mongodb.conf
        echo "bind_ip=0.0.0.0" >> mongodb.conf
        echo "=====>设置Mongodb启动项"
        touch /lib/systemd/system/mongodb.service
        echo "[Unit]" >> /lib/systemd/system/mongodb.service
        echo "Description=mongodb" >> /lib/systemd/system/mongodb.service
        echo "After=network.target remote-fs.target nss-lookup.target" >> /lib/systemd/system/mongodb.service
        echo "[Service]" >> /lib/systemd/system/mongodb.service
        echo "Type=forking" >> /lib/systemd/system/mongodb.service
        echo "ExecStart=/usr/local/mongodb/bin/mongod --config /usr/local/mongodb/bin/mongodb.conf" >>/lib/systemd/system/mongodb.service
        echo "ExecReload=/bin/kill -s HUP $MAINPID" >> /lib/systemd/system/mongodb.service
        echo "ExecStop=/usr/local/mongodb/bin/mongod --shutdown --config /usr/local/mongodb/bin/mongodb.conf" >> /lib/systemd/system/mongodb.service
        echo "PrivateTmp=true" >> /lib/systemd/system/mongodb.service
        echo "[Install]" >> /lib/systemd/system/mongodb.service
        echo "WantedBy=multi-user.target" >> /lib/systemd/system/mongodb.service
        echo "=====> Mongodb配置完毕！";
        systemctl daemon-reload
        systemctl enable mongodb.service
        sed -i '/^PATH/ i\MONGODB_HOME\=\/usr\/local\/mongodb' /etc/profile
        sed -i '/^PATH/ s/$/\:\$MONGODB_HOME\/bin/' /etc/profile
        sed -i '/export/ s/$/\ MONGODB_HOME/' /etc/profile
        source /etc/profile
    else
        echo "=====>安装失败!";
        exit;
    fi
else
    echo "=====>下载失败，结束安装！"
    exit
fi

echo "===>开启mongodb<===";
mongo

刷新环境变量

source /etc/profile

关闭防火墙

systemctl stop firewalld

查看MongoDB的配置文件

# MongoDB的数据存储目录
dbpath=/usr/local/mongodb/data
# 日志保存文件
logpath=/usr/local/mongodb/logs
logappend=true
port=27017
fork=true
# 允许远程访问
bind_ip=0.0.0.0

Mongodb基本操作

systemctl stop mongodb.service
systemctl start mongodb.service

二、启动Springboot项目

pom文件

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

        </dependency>
    </dependencies>

    <build>
        <plugins>
            <plugin>

</project>

yml文件

spring:
  data:
    mongodb:
      uri: mongodb://192.168.1.10/test

创建实体类

import org.springframework.data.mongodb.core.mapping.Document;

import java.io.Serializable;

public class User implements Serializable {

    private static final long serialVersionUID = -1L;

    private Long id;

    private String username;

    private Integer age;

    public User() {
    }

    public User(Long id, String username, Integer age) {
        this.id = id;
        this.username = username;
        this.age = age;
    }

    public Long getId() {
        return id;
    }

    public void setId(Long id) {
        this.id = id;
    }

    public String getUsername() {
        return username;
    }

    public void setUsername(String username) {
        this.username = username;
    }

    public Integer getAge() {
        return age;
    }

    public void setAge(Integer age) {
        this.age = age;
    }

    @Override
    public String toString() {
        return "User{" +
                "id=" + id +
                ", username='" + username + '\'' +
                ", age=" + age +
                '}';
    }
}

Mapper层

import com.mongodb.date.entity.User;
import org.springframework.data.mongodb.repository.MongoRepository;
import org.springframework.stereotype.Repository;

import java.util.List;

@Repository
public interface UserRepository extends MongoRepository<User, Long> {

    User findUserById(Long id);

    List<User> findByAge(Integer age);

}

Service层

import com.mongodb.date.entity.User;

import java.util.List;

public interface UserService {

    User add(User user);

    List<User> findByAge(Integer age);

    User findById(Long id);

}

Service实现类

import com.mongodb.date.entity.User;
import com.mongodb.date.mapper.UserRepository;
import com.mongodb.date.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.mongodb.core.MongoTemplate;
import org.springframework.stereotype.Service;

import java.util.List;

@Service
public class UserServiceImpl implements UserService {

    @Autowired
    private UserRepository userRepository;

    @Autowired
    private MongoTemplate mongoTemplate;

    @Override
    public User add(User user) {
        return userRepository.save(user);
    }

    @Override
    public List<User> findByAge(Integer age) {
        return userRepository.findByAge(age);
    }

    @Override
    public User findById(Long id) {
        return userRepository.findUserById(id);
    }
}

控制器类

import com.mongodb.date.entity.User;
import com.mongodb.date.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.*;

import java.util.List;

@RestController
@RequestMapping("/api")
public class DemoController {

    @Autowired
    private UserService userService;

    @GetMapping("/list/{age}")
    public List<User> getList(@PathVariable("age") Integer age) {
        return userService.findByAge(age);
    }

    @PostMapping("/add")
    public User add(User user) {
        return userService.add(user);
    }

}

三、测试
