软件环境 JDK 1.8 SpringBoot 2.2.1 Maven 3.2 Mysql 8.0.26 spring-boot-starter-data-redis 2.2.1 jedis3.1.0 开发工具 IntelliJ IDEA smartGit
项目搭建
使用Spring官网的https://start.spring.io快速创建Spring Initializr项目 选择maven、jdk版本
选择需要的Dependencies选择一下Spring Data Redis 点击next就可以生成一个Springboot项目不过jedis客户端配置还是要自己加的所以对pom文件做简单的修改spring-boot-starter-data-redis默认使用lettuce所以不用的可以exclusion然后再加上jedis的配置
dependencygroupIdorg.springframework.boot/groupIdartifactIdspring-boot-starter-data-redis/artifactIdexclusionsexclusiongroupIdio.lettuce/groupIdartifactIdlettuce-core/artifactId/exclusion/exclusions
/dependencydependencygroupIdredis.clients/groupIdartifactIdjedis/artifactId
/dependency新建一个application.yml配置文件加上redis一些配置
spring:redis:port: 6379host: 127.0.0.1password:timeout: 3000database: 1jedis:pool:max-idle: 8max-active: 8min-idle: 2
新增Redis配置配置RedisConnectionFactory 为JedisConnectionFactoryJedisPoolRedisTemplate需要用到也可以配置一下
package com.example.jedis.configuration;import lombok.extern.slf4j.Slf4j;
import org.apache.commons.pool2.impl.GenericObjectPool;
import org.springframework.boot.autoconfigure.condition.ConditionalOnClass;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.redis.connection.RedisConnectionFactory;
import org.springframework.data.redis.connection.jedis.JedisConnection;
import org.springframework.data.redis.connection.jedis.JedisConnectionFactory;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.repository.configuration.EnableRedisRepositories;
import org.springframework.data.redis.serializer.GenericJackson2JsonRedisSerializer;
import org.springframework.data.redis.serializer.StringRedisSerializer;
import redis.clients.jedis.Jedis;
import redis.clients.jedis.JedisPool;
import redis.clients.jedis.JedisPoolConfig;Configuration
ConditionalOnClass({GenericObjectPool.class, JedisConnection.class, Jedis.class})
EnableRedisRepositories(basePackages com.example.jedis.repository)
Slf4j
public class RedisConfiguration {Beanpublic JedisPoolConfig jedisPoolConfig() {return new JedisPoolConfig();}Beanpublic JedisPool jedisPool() {return new JedisPool(jedisPoolConfig());}Beanpublic RedisConnectionFactory jedisConnectionFactory() {return new JedisConnectionFactory();}Beanpublic RedisTemplateString, Object redisTemplate() {RedisTemplateString, Object template new RedisTemplateString, Object();template.setConnectionFactory(jedisConnectionFactory());template.setKeySerializer(new StringRedisSerializer());template.setValueSerializer(new GenericJackson2JsonRedisSerializer());return template;}
}写一个实体类RedisHash定义存储的hash key
package com.example.jedis.model;import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.EqualsAndHashCode;
import lombok.NoArgsConstructor;
import lombok.experimental.SuperBuilder;
import org.springframework.data.redis.core.RedisHash;import java.io.Serializable;RedisHash(user)
Data
SuperBuilder(toBuilder true)
EqualsAndHashCode
AllArgsConstructor
NoArgsConstructor
public class UserDto implements Serializable {private static final long serialVersionUID 5962011647926411830L;public enum Gender {MALE, FEMALE}private Long id;private String name;private Gender gender;}
使用Sping Data Redis的API来实现一个CRUD接口
package com.example.jedis.repository;import com.example.jedis.model.UserDto;
import org.springframework.data.repository.CrudRepository;
import org.springframework.stereotype.Repository;Repository
public interface UserRepository extends CrudRepositoryUserDto, Long {
}
写一个测试类来进行测试ContextConfiguration指定一个配置类
package com.example.jedis;import cn.hutool.core.util.IdUtil;
import com.example.jedis.configuration.RedisConfiguration;
import com.example.jedis.model.UserDto;
import com.example.jedis.repository.UserRepository;
import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.test.annotation.DirtiesContext;
import org.springframework.test.context.ContextConfiguration;
import redis.clients.jedis.Jedis;
import redis.clients.jedis.JedisPool;SpringBootTest
ContextConfiguration(classes RedisConfiguration.class)
DirtiesContext(classMode DirtiesContext.ClassMode.BEFORE_CLASS)
class SpringbootJedisApplicationTests {AutowiredJedisPool jedisPool;AutowiredRedisTemplate redisTemplate;AutowiredUserRepository userRepository;Testvoid contextLoads() {Jedis jedis jedisPool.getResource();jedis.set(tKey,你好呀);jedis.close();}Testvoid testRedisTemplate() {redisTemplate.opsForValue().set(rtKey,你好呀);}Testvoid testCrud() {final UserDto userDto UserDto.builder().id(IdUtil.getSnowflake().nextId()).name(用户1).gender(UserDto.Gender.MALE).build();userRepository.save(userDto);}}
