Redis整合SpringBoot

第一步：导入pom文件

        
            org.springframework.boot
            spring-boot-starter-data-redis

第二步：配置我们的redis连接

spring.redis.host: 192.168.1.60
spring.redis.database: 5
spring.redis.password: 123456

示例：

//导入redis实现类
@Autowired
private RedisTemplate redisTemplate;

@Test
void contextLoads() {
redisTemplate.opsForValue().set("key","112233");
System.out.printf(redisTemplate.opsForValue().get("key")+"");
//opsForValue 操作字符串
//opsForHash 操作哈希
//opsForList 操作集合
//opsForSet 操作set
//....................
//以上方法后面直接点出我们的命令就可以直接使用了

//上面是操作数据的方法，一些基本的常用方法我们都是可以直接使用的，比如事物，提交等等等等
redisTemplate.exec()
redisTemplate.multi()
// ................................

//当然还有一些特殊命令
RedisConnection tory = redisTemplate.getConnectionFactory().getConnection();
tory.flushDb();
tory.flushAll();
}

下面我们使用工具类操作我们的Redis :

public class StringRedisTemplate extends RedisTemplate {
    public StringRedisTemplate() {
        this.setKeySerializer(RedisSerializer.string());
        this.setValueSerializer(RedisSerializer.string());
        this.setHashKeySerializer(RedisSerializer.string());
        this.setHashValueSerializer(RedisSerializer.string());
    }

    public StringRedisTemplate(RedisConnectionFactory connectionFactory) {
        this();
        this.setConnectionFactory(connectionFactory);
        this.afterPropertiesSet();
    }

    protected RedisConnection preProcessConnection(RedisConnection connection, boolean existingConnection) {
        return new DefaultStringRedisConnection(connection);
    }
}
