第三步：redis的javaAPI操作
操作string类型数据
/**
* 添加string类型数据
*/
@Test
public void addStr(){
Jedis resource = jedisPool.getResource();
//添加
resource.set("jediskey", "jedisvalue");
//查询
String jediskey = resource.get("jediskey");
System.out.println(jediskey);
//修改
resource.set("jediskey","jedisvalueUpdate");
//删除
resource.del("jediskey");
//实现整型数据的增长操作
resource.incr("jincr");
resource.incrBy("jincr",3);
String jincr = resource.get("jincr");
System.out.println(jincr);
resource.close();
}
操作hash列表类型数据
/**
* 操作hash类型数据
*/
@Test
public void hashOperate(){
Jedis resource = jedisPool.getResource();
//添加数据
resource.hset("jhsetkey","jmapkey","jmapvalue");
resource.hset("jhsetkey","jmapkey2","jmapvalue2");
//获取所有数据
Map<String, String> jhsetkey = resource.hgetAll("jhsetkey");
for (String s : jhsetkey.keySet()) {
System.out.println(s);
}
//修改数据
resource.hset("jhsetkey","jmapkey2","jmapvalueupdate2");
Map<String, String> jhsetkey2 = resource.hgetAll("jhsetkey");
for (String s : jhsetkey2.keySet()) {
System.out.println("修改数据打印"+s);
}
//删除数据
resource.del("jhsetkey");
Set<String> jhsetkey1 = resource.keys("jhsetkey");
for (String result : jhsetkey1) {
System.out.println(result);
}
}
操作list类型数据
/**
* 操作list类型的数据
*/
@Test
public void listOperate(){
Jedis resource = jedisPool.getResource();
//从左边插入元素
resource.lpush("listkey","listvalue1","listvalue1","listvalue2");
//从右边移除元素
resource.rpop("listkey");
//获取所有值
List<String> listkey = resource.lrange("listkey", 0, -1);
for (String s : listkey) {
System.out.println(s);
}
resource.close();
}
操作set类型的数据
/**
* set类型数据操作
*/
@Test
public void setOperate(){
Jedis resource = jedisPool.getResource();
//添加数据
resource.sadd("setkey", "setvalue1", "setvalue1", "setvalue2", "setvalue3");
//查询数据
Set<String> setkey = resource.smembers("setkey");
for (String s : setkey) {
System.out.println(s);
}
//移除掉一个数据
resource.srem("setkey","setvalue3");
resource.close();
}
