关于spring data redis使用javaConfig的基本配置

配置文件内容
@Configuration
@ComponentScan(basePackages = {“com.xd.redis”,“com.xd.dao.*”})
public class RedisConfig {

/**
 * 直接new 一个对象返回，即默认它的各项属性(端口，主机名，密码等等)为默认值，
 * @return
 */
@Bean
public JedisConnectionFactory jedisConnectionFactory(){
    JedisConnectionFactory jedisConnectionFactory = new JedisConnectionFactory(jedisPoolConfig());
    jedisConnectionFactory.setUsePool(true);
    return jedisConnectionFactory;
}

/**
 * jedis连接池配置,直接new 一个对象返回，使用默认值，如有需要可以为其各个属性配置值
 * @return
 */
@Bean
public JedisPoolConfig jedisPoolConfig(){
    return new JedisPoolConfig();
}

@Bean
public RedisTemplate<Serializable, Serializable> redisTemplate(){
    RedisTemplate<Serializable, Serializable> redisTemplate = new RedisTemplate<Serializable, Serializable>();
    redisTemplate.setConnectionFactory(jedisConnectionFactory());
    return redisTemplate;
}

}

下面是对redis存取的代码，是参照的另一位博主的博客，下面有这位博主的的博客的链接：
@Repository
public class UserDao implements IUserDao {

@A**utowired
private RedisTemplate<Serializable, Serializable> redisTemplate;**

public void saveUser(final User user) {

    redisTemplate.execute(new RedisCallback<Object>() {
                              public Object doInRedis(RedisConnection redisConnection) throws DataAccessException {
                                  redisConnection.set(redisTemplate.getStringSerializer().serialize("user.id."+user.getId()),
                                          redisTemplate.getStringSerializer().serialize((user.getUsername())));
                                  return null;
                              }
                          }
    );
}

public User getUser(final long id) {
    return redisTemplate.execute(new RedisCallback<User>() {
        public User doInRedis(RedisConnection redisConnection) throws DataAccessException {
            byte[] key = redisTemplate.getStringSerializer().serialize("user.id."+id);
            if(redisConnection.exists(key)){
                byte[] value = redisConnection.get(key);
                String username = redisTemplate.getStringSerializer().deserialize(value);
                User user = new User();
                user.setUsername(username);
                user.setId(id);

                return user;
            }
            return null;
        }
    });
}

}
