接口必然需要压测，但有时候往往没有专门压测人员，程序员自己动手。以实名接口为例，传入姓名、×××号上有返回一致、不一致等信息，一致信息则插入用户信息表，下次调用时先查询该表，如果有直接返回结果。

1.restful接口
使用springboot很容易搭建接口，过程略
2.造数据
2.1java批量插入数据，略
2.2存储过程造数据
2.3sql造数据
-- 建表
drop table if exists `t_identity_info`;
create table `t_identity_info` (
`id` int(11) not null auto_increment comment '主键id',
`real_name` varchar(20) default null comment '姓名',
`id_card` varchar(18) not null comment '×××号',
`create_time` varchar(19) not null comment '创建时间',
primary key (`id`),
key `index_id_card` (`id_card`)
) engine=innodb auto_increment=1 default charset=utf8 comment='用户信息表';
-- 存储过程
drop procedure if exists insert_t_identity_info_data;
delimiter ;;
create procedure insert_t_identity_info_data()
begin
declare i int;
declare tempName varchar(4);
declare tempAreaCode varchar(6);
declare tempDate varchar(8);
set i = 0;
while i < 10000 do
set tempAreaCode = concat((CEILING(RAND()*1000 mod 50) + 10),(CEILING(RAND()*1000 mod 50) + 10),(CEILING(RAND()*1000 mod 50) + 10)) ;
set tempDate = DATE_FORMAT(date_add(now(), interval - CEILING(RAND()*1000000 mod 10000) day),'%Y%m%d');
set tempName = concat(substring('赵钱孙李周吴郑王冯陈褚卫蒋沈韩',CEILING(RAND()*1000 mod 15),1),
substring('嘉懿煜城懿轩烨伟苑博伟泽熠彤鸿',CEILING(RAND()*1000 mod 15),1));
insert into t_identity_info (real_name,id_card,create_time) values
(tempName,concat(tempDate,CEILING(RAND()*100000) mod 9999+1000),now()),
(tempName,concat(tempDate,CEILING(RAND()*100000) mod 9999+1000),now()),
(tempName,concat(tempDate,CEILING(RAND()*100000) mod 9999+1000),now()),
(tempName,concat(tempDate,CEILING(RAND()*100000) mod 9999+1000),now()),
(tempName,concat(tempDate,CEILING(RAND()*100000) mod 9999+1000),now()),
(tempName,concat(tempDate,CEILING(RAND()*100000) mod 9999+1000),now()),
(tempName,concat(tempDate,CEILING(RAND()*100000) mod 9999+1000),now()),
(tempName,concat(tempDate,CEILING(RAND()*100000) mod 9999+1000),now()),
(tempName,concat(tempDate,CEILING(RAND()*100000) mod 9999+1000),now()),
(tempName,concat(tempDate,CEILING(RAND()*100000) mod 9999+1000),now());
select count(1) from t_identity_info;
set i = i +1;
end while;
end
;;
DELIMITER ;
-- 调用存储过程
call insert_t_identity_info_data();
-- 循环造数据，执行一次数据量*2
insert into t_identity_info(real_name,id_card,create_time) select real_name,id_card,now() from t_identity_info;
完成接口的httpclient
3.压测
运行spring boot
运行n个接口客户端
注意：
不要在本机压测，数据库、服务、客户端都应在服务器上，
压测至少半个小时，根据tps启动客户端个数、每个客户端的数量；
检测服务器的内存、cpu；
考虑网络瓶颈。
