下面进行测试，利用RestClient测试
访问：http://localhost:8080/test/member/add?id=1&nickname=pig
结果
add ok!
查看redis
127.0.0.1:6379> dbsize
(integer) 1
127.0.0.1:6379> get 1
"pig"
127.0.0.1:6379>
访问：http://localhost:8080/test/member/get?id=1
结果
{"id":"1","nickname":"pig"}
访问：http://localhost:8080/test/member/update?id=1&nickname=dog
结果
update ok!
查看redis
127.0.0.1:6379> get 1
"dog"
127.0.0.1:6379>
访问：http://localhost:8080/test/member/get?id=1
结果
{"id":"1","nickname":"dog"}
访问： http://localhost:8080/test/member/delete?id=1
结果
delete ok!
查看redis
127.0.0.1:6379> get 1
(nil)
127.0.0.1:6379>
访问：http://localhost:8080/test/member/get?id=1
结果
null
