Spring Boot整合Redis

一、数据库连接

1、使用redis可视化软件连接redis数据库

二、创建RedisDemo项目

1、创建Spring Boot项目RedisDemo并且完成项目初始化工作

2、在net.hy.lesson08包里创建bean子包，然后创建实体类Address

package net.hy.lesson08.bean;

import org.springframework.data.redis.core.index.Indexed;

/**
 * 功能：地址实体类
 * 作者：黄运
 * 日期：2021年05月17日
 */
public class Address {
    @Indexed
    private String country; //国家
    @Indexed
    private String city; //城市

    public Address(String country, String city) {
        this.country = country;
        this.city = city;
    }

    public String getCountry() {
        return country;
    }

    public void setCountry(String country) {
        this.country = country;
    }

    public String getCity() {
        return city;
    }

    public void setCity(String city) {
        this.city = city;
    }

    @Override
    public String toString() {
        return "Address{" +
                "country='" + country + '\'' +
                ", city='" + city + '\'' +
                '}';
    }
}

3、创建家庭实体类 - Family和个人实体类-Person

Family实体类 -

package net.hy.lesson08.bean;

import org.springframework.data.redis.core.index.Indexed;

/**
 * 功能：家庭实体类
 * 作者：黄运
 * 日期：2021年05月17日
 */
public class Family {
    @Indexed
    private String type; //成员类型
    @Indexed
    private String name; //成员名

    public Family(String type, String name) {
        this.type = type;
        this.name = name;
    }

    public String getType() {
        return type;
    }

    public void setType(String type) {
        this.type = type;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    @Override
    public String toString() {
        return "Family{" +
                "type='" + type + '\'' +
                ", name='" + name + '\'' +
                '}';
    }
}

Person实体类

package net.hy.lesson08.bean;

import org.springframework.data.annotation.Id;
import org.springframework.data.redis.core.RedisHash;
import org.springframework.data.redis.core.index.Indexed;

import java.util.List;

/**
 * 功能：个人实体类
 * 作者：黄运
 * 日期：2021年05月17日
 */
@RedisHash("persons")
public class Person {
    @Id  //主键
    private String id;
    //生成二级索引，方便查询
    @Indexed
    private String firstName; //名
    @Indexed
    private String lastName; //姓
    private Address address; //家庭地址
    private List<Family> familyList; //家庭成员

    public Person(String id, String firstName, String lastName, Address address, List<Family> familyList) {
        this.id = id;
        this.firstName = firstName;
        this.lastName = lastName;
        this.address = address;
        this.familyList = familyList;
    }

    public String getId() {
        return id;
    }

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

    public String getFirstName() {
        return firstName;
    }

    public void setFirstName(String firstName) {
        this.firstName = firstName;
    }

    public String getLastName() {
        return lastName;
    }

    public void setLastName(String lastName) {
        this.lastName = lastName;
    }

    public Address getAddress() {
        return address;
    }

    public void setAddress(Address address) {
        this.address = address;
    }

    public List<Family> getFamilyList() {
        return familyList;
    }

    public void setFamilyList(List<Family> familyList) {
        this.familyList = familyList;
    }

    @Override
    public String toString() {
        return "Person{" +
                "id='" + id + '\'' +
                ", firstName='" + firstName + '\'' +
                ", lastName='" + lastName + '\'' +
                ", address=" + address +
                ", familyList=" + familyList +
                '}';
    }
}

4、创建仓库接口 - PersonRepository

5、在application.properties文件里配置Redis属性

6、在测试类RedisDemoApplicationTests编写测试方法testAddPerson()

@Test
    public void testAddPerson() {
        // 添加第一个人
        Address address = new Address("中国", "泸州");
        Family family1 = new Family("儿子", "张晓刚");
        Family family2 = new Family("女儿", "张晓霞");
        List<Family> familyList = new ArrayList<Family>();
        familyList.add(family1);
        familyList.add(family2);
        Person person = new Person("1", "无忌", "张", address, familyList);
        personRepository.save(person);

        // 添加第二个人
        address = new Address("中国", "上海");
        family1 = new Family("儿子", "李功晨");
        family2 = new Family("女儿", "李晓丽");
        familyList = new ArrayList<Family>();
        familyList.add(family1);
        familyList.add(family2);
        person = new Person("2", "承鹏", "李", address, familyList);
        personRepository.save(person);

        // 添加第三个人
        address = new Address("中国", "北京");
        family1 = new Family("儿子", "唐玉海");
        family2 = new Family("女儿", "唐雨涵");
        familyList = new ArrayList<Family>();
        familyList.add(family1);
        familyList.add(family2);
        person = new Person("3", "大明", "唐", address, familyList);
        personRepository.save(person);

        // 添加第四个人
        address = new Address("中国", "北京");
        family1 = new Family("儿子", "张大明");
        family2 = new Family("女儿", "张丽丽");
        familyList = new ArrayList<Family>();
        familyList.add(family1);
        familyList.add(family2);
        person = new Person("4", "文勇", "张", address, familyList);
        personRepository.save(person);

        System.out.println("成功地添加了4条记录~");
    }

运行结果
