springboot配置redis最简单例子

springboot配置redis最简单例子

解决方法：

1、添加依赖

<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-redis</artifactId>
<version>1.5.6.RELEASE</version>
</dependency>

2、在启动类Application中添加一下配置

@Bean
public RedisTemplate<String, Object> redisTemplate(RedisConnectionFactory factory) {
    RedisTemplate<String, Object> redisTemplate = new RedisTemplate();
    redisTemplate.setConnectionFactory(factory);
return redisTemplate;
}
@Bean
public StringRedisTemplate stringRedisTemplate(RedisConnectionFactory factory) throws UnknownHostException {
    StringRedisTemplate template = new StringRedisTemplate();
    template.setConnectionFactory(factory);
return template;
}

3、保存数据到缓存例子

StringRedisTemplate stringRedisTemplate=(StringRedisTemplate)SpringUtil.getBean(StringRedisTemplate.class);

stringRedisTemplate.executePipelined(new RedisCallback<Object>() {

public Object doInRedis(RedisConnection redisConnection) throws DataAccessException {
        Iterator var2 = list.iterator();//list是从数据库读出来的数据
      while(var2.hasNext()) {
            Object obj = var2.next();
       if (obj != null) {
                String key = "id";
                redisConnection.set(key.getBytes(), JSON.toJSONString(obj).getBytes(), Expiration.seconds(expirationTime), SetOption.UPSERT);
            }
        }
        return null;
    }

4、读取缓存例子

StringRedisTemplate stringRedisTemplate=(StringRedisTemplate)SpringUtil.getBean(StringRedisTemplate.class);

List<String> vals =stringRedisTemplate.opsForValue().multiGet(realKeys);

realKeys是键（id值的集合）的list集合
