本文主要是介绍2021-06-16，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！

Spring Boot整合Redis

（一）搭建Redis环境

1、下载Redis安装压缩包

2、将Redis安装包解压到任意位置

3、给Redis配置环境变量

4、启动Redis服务器

在这里插入图片描述

5、启动Redis客户端

启动命令行窗口，键入redis-cli命令

创建键值对，按键获取值

（二）安装Redis可视化管理工具

Redis可视化工具连接Redis服务

（三）创建Spring Boot项目RedisDemo

在这里插入图片描述
添加项目依赖

（四）创建实体类

在net.user.lesson08包里创建bean子包

1、创建地址实体类 - Address

在net.user.lesson08.bean包里创建地址实体类Address

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


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 + '\'' +
                '}';
    }
}

注意：索引类Indexed不要导入错误 - import org.springframework.data.redis.core.index.Indexed;

2、创建家庭实体类 - Family

在net.user.lesson08.bean包里创建家庭实体类Family

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


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 + '\'' +
                '}';
    }
}

3、创建个人实体类 - Person

在net.user.lesson08.bean包里创建个人实体类Family
在这里插入图片描述

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;

@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 +
                '}';
    }
}

（五）创建仓库接口 - PersonRepository

在net.user.lesson08包里创建repository子包
在net.user.lesson08.repository包里创建PersonRepository接口
在这里插入图片描述

import net.hw.lesson08.bean.Person;
import org.springframework.data.repository.CrudRepository;

public interface PersonRepository extends CrudRepository<Person, String> {
}

（六）在全局配置文件配置Redis属性
