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
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
下载链接：https://pan.baidu.com/s/1EaCKpkGr04QM8QHu3H-G_g
提取码：oonx
Redis可视化工具连接Redis服务
（三）创建Spring Boot项目RedisDemo
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
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
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
（七）在测试类里编写测试方法
点开测试类RedisDemoApplicationTests
注入PersonRepository实例
1、创建测试方法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~");
}
运行测试方法，查看结果
