    <property name="maxIdle" value="300"/>  
    <property name="maxTotal" value="60000"/>

    <property name="timeout" value="${redis.timeout}"></property>
    <property name="password" value="${redis.password}"></property>
    <property name="database" value="${redis.database.business}"></property>

测试用例

    @Benchmark
public void jedis(TestBenchmark state) {

    for (int i = 0; i < 1000; i++) {
        Jedis jedis = jedisPool.getResource();
        jedis.hset("HA", "FA" + i, "VV" + i);
        jedis.close();
    }
    for (int i = 0; i < 1000; i++) {
        Jedis jedis = jedisPool.getResource();

        jedis.hget("HA", "FA" + i);
        jedis.close();
    }

}



 @Benchmark
public void springTemplate(TestBenchmark state) {



    for (int i = 0; i < 1000; i++) {
        template.opsForHash().put("HA", "FA" + i, "VV" + i);
    }
    for (int i = 0; i < 1000; i++) {
        template.opsForHash().get("HA", "FA" + i);
    }

}

结果：

是否有可能通过jedis来创建更多java对象，或者还有其他原因？

填充 jedis：4063712.941±（99.9％）774497.669 us / op [平均]（最小，平均，最大）=（3392560.609，4063712.941，7306286.674），stdev = 891912.667 CI（99.9％）：[3289215.273，4838210.610]（假设正态分布）弹簧模板8127876.567±（99.9％）689718.613 us / op [平均值]（最小，平均，最大值）=（7080667.847，8127876.567，9678719.917），stdev = 794280.981 CI（99.9％）：[7438157.954，8817595.181]（假设正态分布）

为什么Jedis比Spring RedisTemplate快？
