redis的安装直接跳过
1.注册redis服务
在DOM窗口下，进入redis的安装目录（可以先进入安装目录，然后shift+右键，选择在此处打开powershell窗口），
输入命令：
redis-server --service-install redis.windows-service.conf --loglevel verbose；
开启redis服务
打开DOM窗口，输入命令：
redis-server --service-start
关闭redis服务
打开DOM窗口，输入命令：
redis-server --service-stop
到此，redis在windows下的配置便告完成。
2.jedis api的使用
maven引入jedis的依赖：
<dependency>
<groupId>redis.clients</groupId>
<artifactId>jedis</artifactId>
<version>2.1.0</version>
</dependency> <dependency>
<groupId>org.apache.commons</groupId>
<artifactId>commons-lang3</artifactId>
<version>3.3.2</version>
</dependency>
redis.properties文件定义了jedis连接池的一些参数和redis服务器的信息
#config for redis
#最大连接数
redis.pool.maxActive=512
#最大空闲连接数
redis.pool.maxIdle=100
#最大等待等待时间
redis.pool.maxWait=100000
redis.pool.testOnBorrow=true
redis.pool.testOnReturn=true
redis.ip=127.0.0.1
redis.port=6379
#设置过期时间为2小时，超过过期时间会自动删除key-value
redis.expire=7200
注意：在实际的项目文件中不允许出现中文注解
RedisProvider类定义如何获得与redis的连接和释放与redis的连接
public class RedisProvider {
//protected static final Logger LOG = LoggerFactory.getLogger(RedisProvider.class);
protected static JedisPool jedispool;
protected static int EXPIRE = 130;
static{
ResourceBundle bundle = ResourceBundle.getBundle("redis");
if (bundle == null) {
throw new IllegalArgumentException(
"[redis.properties] is not found!");
}
EXPIRE = Integer.valueOf(bundle.getString("redis.expire"));
JedisPoolConfig jedisconfig = new JedisPoolConfig();
jedisconfig.setMaxActive(Integer.valueOf(bundle
.getString("redis.pool.maxActive")));
jedisconfig.setMaxIdle(Integer.valueOf(bundle
.getString("redis.pool.maxIdle")));
jedisconfig.setMaxWait(Long.valueOf(bundle
.getString("redis.pool.maxWait")));
jedisconfig.setTestOnBorrow(Boolean.valueOf(bundle
.getString("redis.pool.testOnBorrow")));
jedisconfig.setTestOnReturn(Boolean.valueOf(bundle
.getString("redis.pool.testOnReturn")));
jedispool = new JedisPool(jedisconfig, bundle.getString("redis.ip"),
Integer.valueOf(bundle.getString("redis.port")), 100000);
}
/*获取资源*/
public static Jedis getJedis() {
Jedis jedis = null;
try {
jedis = jedispool.getResource();
} catch (JedisConnectionException jce) {
ExceptionUtil.getTrace(jce);
try {
Thread.sleep(3000);
} catch (InterruptedException e) {
ExceptionUtil.getTrace(e);
}
jedis = jedispool.getResource();
}
return jedis;
}
/*释放资源*/
public static void returnResource(JedisPool pool, Jedis jedis) {
if (jedis != null) {
pool.returnResource(jedis);
}
}
}
/*资源jedis理解为连接。jedispool理解为连接池*/
RedisHelper定义了利用jedis连接堆redis服务器端进行的各种操作，这里出于应用的需要，只实现了基本的set和get操作，更多的jedis操作可见它的api：
https://tool.oschina.net/uploads/apidocs/
public class RedisHelper extends RedisProvider {
/**
* Set the string value as value of the key. Default settings at save
* time(2000s)
*
* @param key
* @param value
* @return
*/
public static String set(String key, String value) {
Jedis jedis = null;
String rtn = null;
try {
jedis = getJedis();
rtn = jedis.setex(key, EXPIRE, value);
} catch (Exception e) {
//LOG.error(ExceptionUtil.getTrace(e));
jedispool.returnBrokenResource(jedis);
} finally {
returnResource(jedispool, jedis);
}
return rtn;
}
public static String get(String key) {
Jedis jedis = null;
String rtn = null;
try {
jedis = getJedis();
rtn = jedis.get(key);
} catch (Exception e) {
//LOG.error(ExceptionUtil.getTrace(e));
jedispool.returnBrokenResource(jedis);
} finally {
returnResource(jedispool, jedis);
}
return rtn;
}
}
