1.首先是安装redis; 可以去这里(https://github.com/MicrosoftArchive/redis)下载你对应机型的版本.
2.下面就是给工程里添加依赖,每次都说找不到<java.lang.ClassNotFoundException: org.apache.commons.pool2.impl.GenericObjectPoolConfig>,这个是最坑最坑的!我搞的时候我把每个版本下下来,搞了大半天.还是没搞定.最后贴上版本对应ok的几个jar依赖,按照这个去下载添加就好了.
jedis-2.1.0.jar
spring-data-redis-1.0.2.RELEASE.jar
只引入这两个的话,估计也会报上面的那个错,所以下面的两个也要引入
commons-pool-1.5.5.jar
commons-pool2-2.2.jar
3.创建redis.properties
#访问地址 redis_addr=192.168.1.254 #访问端口 redis_port=6379 #授权密码,有没有这一项取决于要连接的redis服务是否设置了此项 redis_auth=test123 #连接池的最大数据库连接数。设为0表示无限制 redis_max_active=1024 #最大空闲数,数据库连接的最大空闲时间。超过空闲时间,数据库连接将被标记为不可用,然后被释放。设为0表示无限制。 redis_max_idle=200 #最大建立连接等待时间。如果超过此时间将接到异常。设为-1表示无限制。 redis_max_wait=10000 #在borrow一个jedis实例时,是否提前进行alidate操作;如果为true,则得到的jedis实例均是可用的; redis_test_on_borrow=true
4.创建spring-redis.xml
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mvc="http://www.springframework.org/schema/mvc"

5.写入redisTemplelate实现类,接口文件省略.
@Service("RedisService")
public class RedisServiceImpl implements RedisService{
@Autowired
private RedisTemplate redisTemplate;

* @param value
* @return
*/
public boolean set(final String key, Object value) {
boolean result = false;
try {
ValueOperations<Serializable, Object> operations = redisTemplate.opsForValue();
operations.set(key, value);
result = true;
} catch (Exception e) {
e.printStackTrace();

return result;

}
6.其实后面的都不重要,随便都可以搞出来,最麻烦的就是各个jar依赖的版本冲突和版本的一些其他问题.只要做好第二步,其他的都就正常了.
