RedisTemplate中opsForValue和opsForList方法的使用详解

//赋值方法
redisTemplate.opsForValue().set("username1","wangxinli");
redisTemplate.opsForValue().set("username2","yanxiaotang");
redisTemplate.opsForValue().set("username3","zhangguoshun");
//取值,返回是String类型
String str1 = redisTemplate.opsForValue().get("username1");
String str2 = redisTemplate.opsForValue().get("username2");
String str3 = redisTemplate.opsForValue().get("username3");

//赋值方法
redisTemplate.opsForValue().set("stu1",new Student(1,"张三",20,"张无忌"));
redisTemplate.opsForValue().set("stu2",new Student(2,"李四",20,"张真人"));
//取值,返回是Student类型
Student stu1 = redisTemplate.opsForValue().get("stu1");
Student stu2 = redisTemplate.opsForValue().get("stu2");

redisTemplate.opsForList().rightPush("user_list","wangxinli");
redisTemplate.opsForList().rightPush("user_list","yanxiaotang");
//push时value传的是什么类型，range方法后接受的list<>中就传什么类型
List<String> lists = redisTemplate.opsForList().range("user_list",0,-1);
for(String str:lists){
 System.out.println(str);
}

//赋值方法
redisTemplate.opsForList().leftPush("stu_list",new Student(1,"张三",20,"张无忌"));
redisTemplate.opsForList().leftPush("stu_list",new Student(2,"李四",20,"张真人"));
/**
leftPushAll方法的value值为数组或list集合,该方法会将value值一次性全部追加存入到该key
值对应的内容中；一般情况下同一个key值对应的追加的数据类型要保持一致，像下面那样先
往stu_list中添加Student对象，再往其中追加list集合或数组，这样的操作不常见，也无必要。
*/
redisTemplate.opsForList().leftPushAll("stu_list",stuArr);
//取值,返回是Student类型
List<Student> lists = redisTemplate.opsForList().range("stu_list",0,-1);
//遍历
for(Student stu:lists){
 System.out.println(stu);
}
