/xml配置文件/redis的配置/redis三种配置和redisTemplate的用法.txt
String url="192.168.153.129";
使用jedis需要导入redis.clients.jedis和org.apache.commons.commons-pool2。
redis.conf的logfile "mylog.log"可以看到日志,loglevel可以设置日志输出级别
1_:使用jedis:
Jedis j = new Jedis(url,6379);
String s=j.get("modules");
System.out.println(s);
========================================================================
2_使用spring整合的带连接池的redis:
在applicationContext.xml里导入applicationContext-redis.xml(a),a的配置:
maven导包,详情见方法3;
JedisPoolConfig c = new JedisPoolConfig();
c.setMaxIdle(10);
c.setMaxTotal(30);
JedisPool jp = new JedisPool(c,url);
Jedis j = jp.getResource();
String s=j.get("modules");
========================================================================
3_使用spring整合的带org.springframework.data.redis.core.RedisTemplate的redis
在主项目的pom里设置:
redis.clients
jedis
2.6.2
org.springframework.data
spring-data-redis
${springdataredis.version}
在applicationContext.xml里导入applicationContext-redis.xml(外面有):
r.boundHashOps(key)/r.boundListOps(key)/r.boundSetOps(key)/r.boundValueOps(key)/
r.boundZSetOps(key)有各自增删改查方法,r.delete(key)也可以删除,
用来直接删除整个list/hash/set/zset,demo如下:
4.5.2值类型操作
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations="classpath:spring/applicationContext-redis.xml")
public class TestValue {
@Autowired
private RedisTemplate redisTemplate;
public void setValue(){
redisTemplate.boundValueOps("name").set("itcast");
}
public void getValue(){
String str = (String) redisTemplate.boundValueOps("name").get();
System.out.println(str);
}
public void deleteValue(){
redisTemplate.delete("name");;
}
}
4.5.3 Set类型操作
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations="classpath:spring/applicationContext-redis.xml")
public class TestSet {
@Autowired
private RedisTemplate redisTemplate;
public void setValue(){
redisTemplate.boundSetOps("nameset").add("曹操");
redisTemplate.boundSetOps("nameset").add("刘备");
redisTemplate.boundSetOps("nameset").add("孙权");
}
public void getValue(){
Set members = redisTemplate.boundSetOps("nameset").members();
System.out.println(members);
}
public void deleteValue(){
redisTemplate.boundSetOps("nameset").remove("孙权");
}
public void deleteAllValue(){
redisTemplate.delete("nameset");
}
}
4.5.4 List类型操作
创建测试类TestList
public void testSetValue1(){
redisTemplate.boundListOps("namelist1").rightPush("刘备");
redisTemplate.boundListOps("namelist1").rightPush("关羽");
redisTemplate.boundListOps("namelist1").rightPush("张飞");
}
public void testGetValue1(){
List list = redisTemplate.boundListOps("namelist1").range(0, 10);
System.out.println(list);
}
public void testSetValue2(){
redisTemplate.boundListOps("namelist2").leftPush("刘备");
redisTemplate.boundListOps("namelist2").leftPush("关羽");
redisTemplate.boundListOps("namelist2").leftPush("张飞");
}
public void testGetValue2(){
List list = redisTemplate.boundListOps("namelist2").range(0, 10);
System.out.println(list);
}
public void testSearchByIndex(){
String s = (String) redisTemplate.boundListOps("namelist1").index(1);
System.out.println(s);
}
public void testRemoveByIndex(){
redisTemplate.boundListOps("namelist1").remove(1, "关羽");
}
4.5.5 Hash类型操作
创建测试类TestHash
public void testSetValue(){
redisTemplate.boundHashOps("namehash").put("a", "唐僧");
redisTemplate.boundHashOps("namehash").put("b", "悟空");
redisTemplate.boundHashOps("namehash").put("c", "八戒");
redisTemplate.boundHashOps("namehash").put("d", "沙僧");
}
public void testGetKeys(){
Set s = redisTemplate.boundHashOps("namehash").keys();
System.out.println(s);
}
public void testGetValues(){
List values = redisTemplate.boundHashOps("namehash").values();
System.out.println(values);
}
public void testGetValueByKey(){
Object object = redisTemplate.boundHashOps("namehash").get("b");
System.out.println(object);
}
public void testRemoveValueByKey(){
redisTemplate.boundHashOps("namehash").delete("c");
