SpringBoot + Redisson Demo

redisson 官网： https://redisson.org/

一、引入 maven 包

<dependency>
      <groupId>org.redisson</groupId>
      <artifactId>redisson-spring-boot-starter</artifactId>
      <version>3.17.0</version>
</dependency>

二、配置 Redis 链接

redisson.redis.host=127.0.0.1
redisson.redis.port=6379
redisson.redis.password=

三、创建 Redisson 客户端Bean

import lombok.Data;
import org.redisson.Redisson;
import org.redisson.api.RedissonClient;
import org.redisson.config.Config;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
@ConfigurationProperties(prefix = "redisson.redis")
@Data
public class RedissonConfig {

    private String host;
    private String port;
    private String password;

    @Bean
    public RedissonClient redissonClient() {
        Config config = new Config();
        config.useSingleServer().setAddress("redis://" + host + ":" + port);    //有不同的模式此处使用Single模式，还有useCustomServers/useSentinelServers/useMasterSlaveServers
        return Redisson.create(config);
    }


}

四、使用Redisson 客户端 进行 存储和查询

import org.redisson.api.RBucket;
import org.redisson.api.RedissonClient;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
import java.util.concurrent.ExecutionException;

@Component
public class RedissonDemo {

    @Autowired
    private RedissonClient redissonClient;

    /**
     * 通用对象桶，可以用来存放任意类型的对象
     */
    public void baseOperate() throws ExecutionException, InterruptedException {
        //同步
        RBucket<String> bucket1 = redissonClient.getBucket("bucket1");
        bucket1.set("Hello World");
        System.out.println(bucket1.get());

        RBucket<String> bucket2 = redissonClient.getBucket("bucket2");
        bucket2.setAsync("Douger").get();
        bucket2.getAsync().thenAccept(System.out::println);

    }

    /**
     * 直接拿之前放置的数据
     */
    public void baseOperate1() throws ExecutionException, InterruptedException {
        //同步
        RBucket<String> bucket1 = redissonClient.getBucket("bucket1");
        System.out.println(bucket1.get());
    }
}

五、 测试

import com.yyds.redis.redisson.RedissonDemo;
import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;

import java.util.concurrent.ExecutionException;

@SpringBootTest
public class RedisBaseOper {

    @Autowired
    private RedissonDemo redissonDemo;

    @Test
    public void baseTest() {
        try {
　　　　　　　redissonDemo.baseOperate();
            redissonDemo.baseOperate1();
        } catch (ExecutionException e) {
            e.printStackTrace();
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
    }

}

运行结果：

 

 此时在 redis 客户端可查看到 key 为 bucket1 和 bucket2 的数据， 除了放入的数据外， 还有一些前缀

127.0.0.1:6379> get bucket1
"\x04>\x0bHello World"
127.0.0.1:6379> get bucket2
"\x04>\x06Douger"
127.0.0.1:6379>
