设置：redisTemplate.opsForValue().set("hello","Helloworld");
代码：System.out.println(redisTemplate.opsForValue().get("hello",0,5));
结果：Hellow
代码：System.out.println(redisTemplate.opsForValue().get("hello",0,-1));
结果：Helloworld
代码：System.out.println(redisTemplate.opsForValue().get("hello",-3,-1));
结果：rld			
			
			

			
redisTemplate.opsForValue().append("hello","Hello");
System.out.println(redisTemplate.opsForValue().get("hello"));

redisTemplate.opsForValue().append("hello","world");
System.out.println(redisTemplate.opsForValue().get("hello")); // 结果：Helloworld        			
			
			

			
	redisTemplate.opsForValue().set("name","neo");
    System.out.println(redisTemplate.opsForValue().getAndSet("name","Jerry"));
	// 结果 neo			
			
			

			
redisTemplate.opsForValue().set("key","hello world");
System.out.println(redisTemplate.opsForValue().size("key"));			
			
			

			
System.out.println(redisTemplate.opsForValue().setIfAbsent("name","neo"));	// name 之前已经存在 false
System.out.println(redisTemplate.opsForValue().setIfAbsent("age","11"));		// age 之前不存在	true
			
			

setIfAbsent 实现分布式锁

			
boolean static = Boolean.TRUE.equals(redisTemplate.opsForValue().setIfAbsent("lock:order", 1, 1, TimeUnit.DAYS));			
			
			

			
Map<String,String> maps = new HashMap<String, String>();
	maps.put("multi1","multi1");
	maps.put("multi2","multi2");
	maps.put("multi3","multi3");

redisTemplate.opsForValue().multiSet(maps);

List<String> keys = new ArrayList<String>();
	keys.add("multi1");
	keys.add("multi2");
	keys.add("multi3");

System.out.println(redisTemplate.opsForValue().multiGet(keys));			
			
			

输出结果

			
[multi1, multi2, multi3]			
			
			

为多个键分别设置它们的值，如果存在则返回false，不存在返回true

			
Map<String,String> maps = new HashMap<String, String>();
        maps.put("multi11","multi11");
        maps.put("multi22","multi22");
        maps.put("multi33","multi33");
Map<String,String> maps2 = new HashMap<String, String>();
        maps2.put("multi1","multi1");
        maps2.put("multi2","multi2");
        maps2.put("multi3","multi3");

System.out.println(redisTemplate.opsForValue().multiSetIfAbsent(maps)); 	// 返回 true
System.out.println(redisTemplate.opsForValue().multiSetIfAbsent(maps2));	// 返回 false
			
			

			
setBit Boolean setBit(K key, long offset, boolean value);

offset 二进制位置(从左向右数)
value 位 ture 表示 0，false 表示 1			
			
			

			
    // 'a' 的ASCII码是 97 转换为二进制是：01100001
    // 'b' 的ASCII码是 98 转换为二进制是：01100010
    // 'c' 的ASCII码是 99 转换为二进制是：01100011
    			
	redisTemplate.opsForValue().set("bitTest","a");    
    
    redisTemplate.opsForValue().setBit("bitTest",7, false); 	// 01100011
    redisTemplate.opsForValue().setBit("bitTest",8, true);	// 01100010
    System.out.println(redisTemplate.opsForValue().get("bitTest"));
    redisTemplate.opsForValue().setBit("bitTest",8, false);	// 01100011
    System.out.println(redisTemplate.opsForValue().get("bitTest"));			
			
			

getBit Boolean getBit(K key, long offset); 获取键对应值的ascii码的在offset处位值

			
System.out.println(redisTemplate.opsForValue().getBit("bitTest",7));
