1. Create a web project in IDE

two。 Add maven dependencies in pom.xml files

Org.springframework.boot

Spring-boot-starter-parent

1.5.9.RELEASE

Org.springframework.boot

Spring-boot-starter-web

3. Create the program entry class Application.java

Package com.xuejia.ad

Import org.springframework.boot.SpringApplication

Import org.springframework.boot.autoconfigure.SpringBootApplication

/ * *

* @ author kehaojian

* @ date 2017-12-28 8:33

* @ since 1.0.0

, /

@ SpringBootApplication

Public class Application {

Public static void main (String [] args) {

SpringApplication.run (Application.class, args)

}

}

4. Create a controller class

Package com.xuejia.ad.controller

Import org.springframework.web.bind.annotation.RequestMapping

Import org.springframework.web.bind.annotation.RestController

/ * *

* @ author kehaojian

* @ date 2017-12-28 8:35

* @ since 1.0.0

, /

@ RestController

Public class StartDemoController {

@ RequestMapping ("/")

String home () {

Return "hello"

}

}

5. Configure application.yml

Server:

Port: 8888

Tomcat:

Uri-encoding: utf-8

Spring:

Redis:

Host: localhost

Port: 6379

Pool:

Max-active: 8

Min-idle: 0

Max-idle: 8

Max-wait:-1

5. Run the main method of Application

6. Enter http://localhost:8888/ in the browser

7. Add spring-boot-starter-redis and spring-boot-starter-test dependency packages to pom.xml

Org.springframework.boot

Spring-boot-starter-test

Org.springframework.boot

Spring-boot-starter-redis

8. Create the redis configuration class RedisConfig

Package com.xuejia.ad.config

Import com.fasterxml.jackson.annotation.JsonAutoDetect

Import com.fasterxml.jackson.annotation.PropertyAccessor

Import com.fasterxml.jackson.databind.ObjectMapper

Import org.slf4j.Logger

Import org.slf4j.LoggerFactory

Import org.springframework.boot.context.properties.ConfigurationProperties

Import org.springframework.context.annotation.Bean

Import org.springframework.context.annotation.Configuration

Import org.springframework.data.redis.connection.RedisConnectionFactory

Import org.springframework.data.redis.connection.jedis.JedisConnectionFactory

Import org.springframework.data.redis.core.RedisTemplate

Import org.springframework.data.redis.core.StringRedisTemplate

Import org.springframework.data.redis.serializer.Jackson2JsonRedisSerializer

Import redis.clients.jedis.JedisPoolConfig

, /

@ Configuration

@ ConfigurationProperties (prefix= "spring.redis")

Public class RedisConfig {

Private static Logger logger = LoggerFactory.getLogger (RedisConfig.class)

/ * @ Bean

Public RedisTemplate redisTemplate (RedisConnectionFactory redisConnectionFactory) {

StringRedisTemplate template = new StringRedisTemplate (redisConnectionFactory)

Jackson2JsonRedisSerializer jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer (Object.class)

ObjectMapper objectMapper = new ObjectMapper ()

ObjectMapper.setVisibility (PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY)

ObjectMapper.enableDefaultTyping (ObjectMapper.DefaultTyping.NON_FINAL)

Jackson2JsonRedisSerializer.setObjectMapper (objectMapper)

Template.setValueSerializer (jackson2JsonRedisSerializer)

Template.afterPropertiesSet ()

Return template

}

, /

@ Bean

Public JedisPoolConfig getRedisConfig () {

JedisPoolConfig config = new JedisPoolConfig ()

Return config

}

@ Bean

Public JedisConnectionFactory getConnectionFactory () {

JedisConnectionFactory factory = new JedisConnectionFactory ()

JedisPoolConfig config = getRedisConfig ()

Factory.setPoolConfig (config)

Logger.info ("JedisConnectionFactory bean init success.")

Return factory

}

@ Bean

Public RedisTemplate getRedisTemplate () {

RedisTemplate template = new StringRedisTemplate (getConnectionFactory ())

Return template

}

}

9. Create a redis simple utility class

Package com.xuejia.ad.common

Import org.springframework.beans.factory.annotation.Autowired

Import org.springframework.data.redis.core.RedisTemplate

Import org.springframework.stereotype.Repository

Import java.util.concurrent.TimeUnit

/ * *

* @ author kehaojian

* @ date 2017-12-28 9:04

* @ since 1.0.0

, /

@ Repository

Public class RedisUtil {

@ Autowired

Private RedisTemplate redisTemplate

Public void add (String key, String value, Long time) {

RedisTemplate.opsForValue () .set (key, value, time, TimeUnit.SECONDS)

}

Public String get (String key) {

Return redisTemplate.opsForValue () get (key)

}

Public void delete (String key) {

RedisTemplate.opsForValue (). GetOperations (). Delete (key)

}

}

10. Create a test class RedisTest in the test directory

Import com.xuejia.ad.common.RedisUtil

Import com.xuejia.ad.config.RedisConfig

Import org.junit.Before

Import org.junit.Test

Import org.junit.runner.RunWith

Import org.springframework.beans.factory.annotation.Autowired

Import org.springframework.test.context.ContextConfiguration

Import org.springframework.test.context.junit4.SpringJUnit4Cla***unner

/ * *

* @ author kehaojian

* @ date 2017-12-28 9:17

* @ since 1.0.0

, /

@ RunWith (SpringJUnit4Cla***unner.class)

@ ContextConfiguration (classes = {RedisConfig.class, RedisUtil.class})

Public class RedisTest {

@ Autowired

Private RedisUtil redisUtil

@ Before

Public void testbefore () {

RedisUtil.add ("kehaojian", "helloworld", 100L)

}

@ Test

Public void testRedis () throws InterruptedException {

Int total = 20
