源代码下载: http://download.csdn.net/detail/jiangtao_st/7623113
1、Maven配置
<dependency> <groupId>redis.clients</groupId> <artifactId>jedis</artifactId> <version>2.5.0</version> </dependency> <dependency> <groupId>com.alibaba</groupId> <artifactId>fastjson</artifactId> <version>1.1.41</version> </dependency></span>
2、Properties 配置文件
redis.pool.maxActive= 100
redis.pool.maxIdle= 20
redis.pool.maxWait= 3000
redis.ip= localhost
redis.port= 6379
3、代码具体实现的Client
/**
*
* <p>
* Redis客户端访问
* </p>
*
* @author 卓轩
* @创建时间:2014年7月11日
* @version: V1.0
*/
public class RedisClient {
public static JedisPool jedisPool;
static {
ResourceBundle resourceBundle = ResourceBundle.getBundle("redis");
int maxActive = Integer.parseInt(resourceBundle.getString("redis.pool.maxActive"));
int maxIdle = Integer.parseInt(resourceBundle.getString("redis.pool.maxIdle"));
int maxWait = Integer.parseInt(resourceBundle.getString("redis.pool.maxWait"));
String ip = resourceBundle.getString("redis.ip");
int port = Integer.parseInt(resourceBundle.getString("redis.port"));
JedisPoolConfig config = new JedisPoolConfig();
config.setMaxTotal(maxActive);
config.setMaxIdle(maxIdle);
config.setMaxWaitMillis(maxWait);
jedisPool = new JedisPool(config, ip, port);
}
/**
* 向缓存中设置字符串内容
* @param key key
* @param value value
* @return
* @throws Exception
*/
public static boolean set(String key,String value) throws Exception{
Jedis jedis = null;
try {
jedis = jedisPool.getResource();
jedis.set(key, value);
return true;
} catch (Exception e) {
e.printStackTrace();
return false;
}finally{
jedisPool.returnResource(jedis);
}
}
/**
* 向缓存中设置对象
* @param key
* @param value
* @return
*/
public static boolean set(String key,Object value){
Jedis jedis = null;
try {
String objectJson = JSON.toJSONString(value);
jedis = jedisPool.getResource();
jedis.set(key, objectJson);
return true;
} catch (Exception e) {
e.printStackTrace();
return false;
}finally{
jedisPool.returnResource(jedis);
}
}
/**
* 删除缓存中得对象,根据key
* @param key
* @return
*/
public static boolean del(String key){
Jedis jedis = null;
try {
jedis = jedisPool.getResource();
jedis.del(key);
return true;
} catch (Exception e) {
e.printStackTrace();
return false;
}finally{
jedisPool.returnResource(jedis);
}
}
/**
* 根据key 获取内容
* @param key
* @return
*/
public static Object get(String key){
Jedis jedis = null;
try {
jedis = jedisPool.getResource();
Object value = jedis.get(key);
return value;
} catch (Exception e) {
e.printStackTrace();
return false;
}finally{
jedisPool.returnResource(jedis);
}
}
/**
* 根据key 获取对象
* @param key
* @return
*/
public static <T> T get(String key,Class<T> clazz){
Jedis jedis = null;
try {
jedis = jedisPool.getResource();
String value = jedis.get(key);
return JSON.parseObject(value, clazz);
} catch (Exception e) {
e.printStackTrace();
return null;
}finally{
jedisPool.returnResource(jedis);
}
}
}
4、 单元测试、保存对象、写入对象
/**
*
* <p>
* 测试独立redis 客户端
* </p>
*
* @author 卓轩
* @创建时间:2014年7月11日
* @version: V1.0
*/
public class SimpleClient {
@Test
public void userCache(){
UserDO zhuoxuan = new UserDO();
zhuoxuan.setUserId(113445);
zhuoxuan.setSex(1);
zhuoxuan.setUname("卓轩");
zhuoxuan.setUnick("zhuoxuan");
zhuoxuan.setEmail("zhuoxuan@mogujie.com");
boolean reusltCache = RedisClient.set("zhuoxuan", zhuoxuan);
if (reusltCache) {
System.out.println("向缓存中保存对象成功。");
}else{
System.out.println("向缓存中保存对象失败。");
}
}
@Test
public void getUserInfo(){
UserDO zhuoxuan = RedisClient.get("zhuoxuan",UserDO.class);
if(zhuoxuan != null){
System.out.println("从缓存中获取的对象," + zhuoxuan.getUname() + "@" + zhuoxuan.getEmail());
}
}
}
Redis缓存系统-Java-Jedis操作Redis,基本操作以及 实现对象保存
