Today, the editor will share with you the relevant knowledge points about how SpringBoot integrates SpringDataRedis. The content is detailed and the logic is clear. I believe most people still know too much about this knowledge, so share this article for your reference. I hope you can get something after reading this article. Let's take a look at it.

SpringBoot integrates SpringDataRedis

1. Create a project to add dependencies

   creates the SpringBoot project and adds the following dependencies:

Org.springframework.boot

Spring-boot-starter-web

Org.springframework.boot

Spring-boot-starter-data-redis

Org.springframework.boot

Spring-boot-starter-test

Test

Redis.clients

Jedis

two。 Set up the application.properties file

Spring.redis.jedis.pool.max-idle=10

Spring.redis.jedis.pool.min-idle=5

Spring.redis.pool.max-total=20

Spring.redis.hostName=192.168.88.120

Spring.redis.port=6379

3. Add a configuration class for Redis

   adds Redis's java configuration class to set relevant information.

@ Configuration

Public class RedisConfig {

/ * *

* 1. Create a JedisPoolConfig object. Complete some link pool configuration in this object

* @ ConfigurationProperties: creates an entity with the same prefix.

, /

@ Bean

@ ConfigurationProperties (prefix= "spring.redis.pool")

Public JedisPoolConfig jedisPoolConfig () {

JedisPoolConfig config = new JedisPoolConfig ()

/ * / maximum free time

Config.setMaxIdle (10)

/ / minimum free time

Config.setMinIdle (5)

/ / maximum number of links

Config.setMaxTotal (20);

System.out.println ("default:" + config.getMaxIdle ())

System.out.println ("default:" + config.getMinIdle ())

System.out.println ("default:" + config.getMaxTotal ())

Return config

}

/ * *

* 2. Create JedisConnectionFactory: configure redis link information

, /

@ Bean

@ ConfigurationProperties (prefix= "spring.redis")

Public JedisConnectionFactory jedisConnectionFactory (JedisPoolConfig config) {

System.out.println ("configuration completed:" + config.getMaxIdle ())

System.out.println ("configuration completed:" + config.getMinIdle ())

System.out.println ("configuration completed:" + config.getMaxTotal ())

JedisConnectionFactory factory = new JedisConnectionFactory ()

/ / the configuration object of the associated link pool

Factory.setPoolConfig (config)

/ / configure the information of the link Redis

/ / Host address

/ * factory.setHostName ("192.168.70.128")

/ / Port

Factory.setPort (6379);

Return factory

}

/ * *

* 3. Create RedisTemplate: the method used to perform Redis operations

, /

@ Bean

Public RedisTemplate redisTemplate (JedisConnectionFactory factory) {

RedisTemplate template = new RedisTemplate ()

/ / Association

Template.setConnectionFactory (factory)

/ / set the serializer for key

Template.setKeySerializer (new StringRedisSerializer ())

/ / set the serializer for value

Template.setValueSerializer (new StringRedisSerializer ())

Return template

}

5. Unit testing

@ RunWith (SpringRunner.class)

@ SpringBootTest (classes = SpringbootRedisDemoApplication.class)

Public class SpringbootRedisDemoApplicationTests {

@ Autowired

Private RedisTemplate redisTemplate

/ * *

* add a string

, /

@ Test

Public void testSet () {

This.redisTemplate.opsForValue () .set ("key", "bobokaoya...")

}

/ * *

* get a string

, /

@ Test

Public void testGet () {

String value = (String) this.redisTemplate.opsForValue () .get ("key")

System.out.println (value)

}

/ * *

* add Users object

, /

@ Test

Public void testSetUesrs () {

Users users = new Users ()

Users.setAge (20)

Users.setName ("Zhang Sanfeng")

Users.setId (1)

/ / reset the serializer

This.redisTemplate.setValueSerializer (new JdkSerializationRedisSerializer ())

This.redisTemplate.opsForValue () .set (users, users)

}

/ * *

* fetch Users object

, /

@ Test

Public void testGetUsers () {

/ / reset the serializer

This.redisTemplate.setValueSerializer (new JdkSerializationRedisSerializer ())

Users users = (Users) this.redisTemplate.opsForValue () .get ("users")

System.out.println (users)

}

/ * *

* storing Users objects based on JSON format

, /

@ Test

Public void testSetUsersUseJSON () {

Users users = new Users ()

Users.setAge (20)

Users.setName ("Li Sifeng")

Users.setId (1)

This.redisTemplate.setValueSerializer (new Jackson2JsonRedisSerializer (Users.class))

This.redisTemplate.opsForValue () .set (users_json, users)

}

/ * *

* fetching Users objects based on JSON format

, /

@ Test

Public void testGetUseJSON () {

This.redisTemplate.setValueSerializer (new Jackson2JsonRedisSerializer (Users.class))

Users users = (Users) this.redisTemplate.opsForValue () .get ("users_json")

System.out.println (users)

}
