详解Spring Boot Redis集成配置
spring Boot 熟悉后,集成一个外部扩展是一件很容易的事,集成Redis也很简单,以下是百分网小编搜索整理的'关于详解Spring Boot Redis集成配置,供参考学习,希望对大家有所帮助!想了解更多相关信息请持续关注我们应届毕业生考试网!
一、添加pom依赖
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-redis</artifactId>
</dependency>
二、创建 RedisClient.java
注意该类存放的package
package org.springframework.data.redis.connection.jedis;
import java.io.ByteArrayInputStream;
import java.io.ByteArrayOutputStream;
import java.io.IOException;
import java.io.ObjectInputStream;
import java.io.ObjectOutputStream;
import java.io.UnsupportedEncodingException;
import org.apache.commons.lang3.StringUtils;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import redis.clients.jedis.Jedis;
import redis.clients.jedis.Protocol;
import redis.clients.jedis.exceptions.JedisException;
/**
* 工具类 RedisClient
* 因为本类中获取JedisPool调用的是JedisConnectionFactory中protected修饰的方法fetchJedisConnector()
* 所以该类需要与JedisConnectionFactory在同一个package中
