2021-5-17：Spring Boot整合Redis

Spring Boot整合Redis

在老师博客中下载压缩包

下载后，解压到D盘，在D:\Program Files目录下新建一个文件夹redis，解压到目录中。

配置环境变量

启动Redis服务器，启动命令行窗口，键入redis-server命令

启动Redis客户端
启动命令行窗口，键入redis-cli命令

键入exit命令，退出客户端

（二）安装Redis可视化管理工具
1、下载Redis可视化管理工具
下载链接：https://pan.baidu.com/s/1EaCKpkGr04QM8QHu3H-G_g
提取码：oonx

下载好后，双击它

创建Spring Boot项目RedisDemo
设置项目元数据

创建实体类
在net.lhf.lesson08包里创建bean子包
1、创建地址实体类Address
在net.lhf.lesson08.bean包里创建地址实体类Address

package net.lhf.lesson08.bean;import org.springframework.data.redis.core.index.Indexed;/*** 功能：地址实体类* 作者：李红芙* 日期：2021年07月17日*/
public class Address {@Indexedprivate String country; //国家@Indexedprivate 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;}@Overridepublic String toString() {return "Address{" +"country='" + country + '\'' +", city='" + city + '\'' +'}';}
}

创建人实体类Person
在net.lhf.lesson08.bean包里创建人实体类Family

package net.lhf.lesson08.bean;
import org.springframework.data.redis.core.index.Indexed;/*** 功能：家庭实体类* 作者：李红芙* 日期：2021年05月17日*/
public class Family {@Indexedprivate String type; //成员类型@Indexedprivate 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;}@Overridepublic String toString() {return "Family{" +"type='" + type + '\'' +", name='" + name + '\'' +'}';}
}

创建人实体类Person
在net.lhf.lesson08.bean包里创建人实体类Person

package net.lhf.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：人实体类* 作者：李红芙* 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@Indexedprivate String firstName; //名@Indexedprivate 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;}@Overridepublic String toString() {return "Person{" +"id='" + id + '\'' +", firstName='" + firstName + '\'' +", lastName='" + lastName + '\'' +", address=" + address +", familyList=" + familyList +'}';}
}

（五）创建自定义Repository接口
在net.lhf.lesson08包里创建repository子包
在net.lhf.lesson08.repository包里创建PersonRepository接口

在全局配置文件配置Redis属性

spring.redis.port=6379
spring.redis.host=127.0.0.1
spring.redis.password=

在测试类里编写测试方法
点开测试类RedisDemoApplicationTests

package net.lhf.lesson08;import net.lhf.lesson08.bean.Address;
import net.lhf.lesson08.bean.Family;
import net.lhf.lesson08.bean.Person;
import net.lhf.lesson08.repository.PersonRepository;
import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;import java.util.ArrayList;
import java.util.List;@SpringBootTest
class RedisDemoApplicationTests {//注入仓库@Autowiredprivate PersonRepository personRepository;@Testvoid contextLoads() {}@Testpublic 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~");}}

说明：在这个测试方法里，测试了personRepository的save()方法

运行测试方法，查看结果

在命令行窗口启动redis服务

打开Redis可视化工具查看

创建测试方法testFindAll()

运行测试方法，查看结果

测试personRespository的其它方法
创建测试方法testFindById()

运行测试方法，查看结果

创建测试方法testDeleteAll()

package net.lhf.lesson08;import net.lhf.lesson08.bean.Address;
import net.lhf.lesson08.bean.Family;
import net.lhf.lesson08.bean.Person;
import net.lhf.lesson08.repository.PersonRepository;
import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;import java.util.ArrayList;
import java.util.List;
import java.util.Optional;@SpringBootTest
class RedisDemoApplicationTests {//注入仓库@Autowiredprivate PersonRepository personRepository;@Testvoid contextLoads() {}@Testpublic 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~");}@Testpublic void testFindAll(){Iterable<Person> persons = personRepository.findAll();persons.forEach(person -> System.out.println(person));}@Testpublic void testFindById() {Optional<Person> person = personRepository.findById("2");System.out.println(person.get());}@Testpublic void testDeleteAll(){personRepository.deleteAll();System.out.println();}
}
