redis-事务管理

模式：watch...multi....exec

watch是加锁，multi是要执行的逻辑，exec是执行，未执行前所有multi中的语句是不会执行。

@RequestMapping("/multi")
    @ResponseBody
    public Map<String, Object> testMulti() {
        redisTemplate.execute(new SessionCallback() {
            @Override
            public Object execute(RedisOperations redisOperations) throws DataAccessException {
                redisOperations.watch("value1");//锁定value1
                redisOperations.multi();
                redisOperations.opsForValue().set("value1","val");
                redisOperations.opsForValue().set("value2","val2");

                return redisOperations.exec();  //执行
            }
        });

        Map<String, Object> map = new HashMap<String, Object>();
        map.put("success", true);
        return map;
    }
