SpringBoot整合Redis

Jedis操作Redis

1、引入maven依赖

代码语言：html复制

<dependency>
<groupId>redis.clients</groupId>
<artifactId>jedis</artifactId>
<version>4.2.1</version>
</dependency>

2、使用api操作redis

代码语言：javascript复制

SpringBoot整合Redis

1、引入redis的maven配置

代码语言：html复制

            </plugins>
        </pluginManagement>
    </build>
</project>

2、application.properties中配置redis信息

代码语言：javascript复制

# redis 服 务 器 ip
spring.redis.host=192.168.18.53
# redis 服务器端口
spring.redis.port=6380
# redis 密码
spring.redis.password=123456
# 连接超时时间（毫秒）
spring.redis.timeout=60000
# Redis默认情况下有16个分片，这里配置具体使用的分片，默认是0
spring.redis.database=0

3、使用RedisTemplate工具类操作redis

代码语言：javascript复制

this.redisTemplate.opsForValue(); //提供了操作string类型的所有方法
this.redisTemplate.opsForList(); // 提供了操作list类型的所有方法
this.redisTemplate.opsForSet(); //提供了操作set的所有方法
this.redisTemplate.opsForHash(); //提供了操作hash表的所有方法
this.redisTemplate.opsForZSet(); //提供了操作zset的所有方法

    }

    /**

    @RequestMapping("hashTest")
    public Map<Object, Object> hashTest()
    { this.redisTemplate.delete("userMap");
        Map<String, String> map = new HashMap<>();

    @RequestMapping("zsetTest")
    public Set<String> zsetTest() {
        this.redisTemplate.delete("languages");
        this.redisTemplate.opsForZSet().add("languages", "java", 100);
        this.redisTemplate.opsForZSet().add("languages", "c  ", 95);
        this.redisTemplate.opsForZSet().add("languages", "php", 70);
        this.redisTemplate.opsForZSet().add("languages", "python", 33);
        Set<String> languages =
                this.redisTemplate.opsForZSet().range("languages", 0, -1);
        return languages;
    }
}
