SpringBoot緩存技術整合SpringData Redis

首先說明一下，這里使用的是Springboot2.2.6.RELEASE版本，由於Springboot迭代很快，所以要注意版本問題。

1、SpringData Redis是屬於SpringData下的一個模塊。作用就是簡化對於redis的操作。SpringData JPA為了簡化對數據庫的操作。修改pom文件添加SpringData Redis的坐標。

編寫SpringData Redis的配置類，替代了之前的配置文件。

編寫測試代碼，測試整合環境。

是Jedis版本問題：將Jedis改為 3.0.0版本或者2.10.1版本后即可解決。我是將Jedis2.9.0版本改為了Jedis3.0.0版本解決了問題。

<!-- jedis是操作redis的工具依賴包 -->
<dependency>
    <groupId>redis.clients</groupId>
    <artifactId>jedis</artifactId>
    <version>3.0.0</version>
</dependency>

提取redis的配置信息，在application.properties配置文件中新增配置信息。 

# 最大空閑數,最后綴必須固定
spring.redis.jedis.pool.max-idle=10
# 最小空閑數,連接池中最小空閑連接
spring.redis.jedis.pool.min-idle=10
# 最大鏈接數,連接池最大連接數（使用負值表示沒有限制）
spring.redis.jedis.pool.max-active=8
# 當池內沒有可用的連接時，最大等待時間
spring.redis.jedis.pool.max-wait=-1ms



# 設置redis的主機
spring.redis.hostName=192.168.110.140
# 設置redis的端口號
spring.redis.port=6379
# 設置操作第一個數據庫
spring.redis.database=0

修改配置類，配置屬性在application.properties進行設置。

使用上面的測試類進行測試，觀察控制台，可以看出一些配置信息。

Spring Boot整合Spring Data Redis，來進行存取Java對象。Spring Data Redis 操作實體對象。創建實體類，方便進行存儲對象。

package com.bie.springboot.po;

import java.io.Serializable;

public class Users implements Serializable {

    private Integer id;
    private String name;
    private Integer age;

    public Integer getId() {
        return id;
    }

    public void setId(Integer id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public Integer getAge() {
        return age;
    }

    public void setAge(Integer age) {
        this.age = age;
    }

    public Users(Integer id, String name, Integer age) {
        this.id = id;
        this.name = name;
        this.age = age;
    }

    @Override
    public String toString() {
        return "Users{" +

    public Users() {

}

使用測試類，開始進行測試。
