"Springboot Series 2" Springboot Integrated Redis

Objective:

Really more and more like Springboot, this is one of the Springboot Learning series.

Body:

1: First add dependency in pom file, Remember is Spring-boot-starter-data-redis, not Spring-boot-starter-redis

1 <!--Redis -2 <Dependency>3     <groupId>Org.springframework.boot</groupId>4     <Artifactid>Spring-boot-starter-data-redis</Artifactid>5 </Dependency>

2: Step two Configure the data source in the properties file

1 # Redis 2 spring.redis.host=120.78.159.xxx 3 spring.redis.port=xxxx 4 spring.redis.password=xxxx

3: Third step, direct injection can

1 @Autowired 2 stringredistemplate Redis;

is not very cool, I used to be stunned, how can be so simple, so concise, too feel the open source community of the great God invented the Springboot this framework.

Attach the official api:https://docs.spring.io/spring-data/redis/docs/current/api/org/springframework/data/redis/core/ Stringredistemplate.html

Usage:

1: Test whether Redis is successful, and take some key values out

1 //Test Redis2@RequestMapping (value = "/testredis", method =requestmethod.get)3      PublicString Testredis () {4         5list<string> list =NewArraylist<>();6List.add ("K1");7List.add ("K2");8List.add ("K3");9 System.out.println (Redis.opsforvalue (). Multiget (list));Ten          One         returnRedis.opsforvalue (). Multiget (list). toString (); A}

2: Test set data into Redis, and set timeout mechanism

1 //put key2@RequestMapping (value = "/putredis/{id}", method =requestmethod.get)3      PublicString Putredis (@PathVariable (value = "id") (String ID) {4         5String key = "Test:" +ID;6String value = "I Love Zxx";7 Redis.opsforvalue (). Set (key, value);8 Redis.expire (Key, Integer.max_value, timeunit.seconds);9         Ten         return"Put Key to Redis"; One}

3: Test from Redis inside get data out

 1  //  Get key  2  @RequestMapping (value = "/getredis/{id}", Method = Requestmethod.get)  3  public  string Getredis (@PathVariable (value = "id"  4  5  String key =" Test: "+ ID;  6   System.out.println (Redis.opsforvalue (). Get ( key));  7  8  r Eturn  "Get key from Redis" ;  9 }
