SpringMVC集成Redis

（1）添加pom依赖

     <dependency>
       <groupId>org.springframework.data</groupId>
       <artifactId>spring-data-redis</artifactId>
       <version>1.8.18.RELEASE</version>
     </dependency>
     <dependency>
       <groupId>org.apache.commons</groupId>
       <artifactId>commons-pool2</artifactId>
       <version>2.6.0</version>
     </dependency>
     <dependency>
         <groupId>redis.clients</groupId>
         <artifactId>jedis</artifactId>
         <version>2.9.0</version>
     </dependency>
     <dependency>
       <groupId>com.fasterxml.jackson.core</groupId>
       <artifactId>jackson-databind</artifactId>
       <version>2.9.8</version>
     </dependency>

（2）注册相关bean

 package cn.coreqi.config;

 import cn.coreqi.entities.User;
 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.serializer.Jackson2JsonRedisSerializer;
 import org.springframework.data.redis.serializer.StringRedisSerializer;

 @Configuration
 public class RedisConfig {
 //    @Bean
 //    public RedisConnectionFactory redis(){
 //        RedisStandaloneConfiguration redisStandaloneConfiguration = new RedisStandaloneConfiguration();
 //        redisStandaloneConfiguration.setHostName("192.168.205.128");
 //        redisStandaloneConfiguration.setPort(6379);
 //        redisStandaloneConfiguration.setDatabase(0);
 //        //redisStandaloneConfiguration.setPassword(RedisPassword.of("123456"));
 //
 //        JedisClientConfiguration.JedisClientConfigurationBuilder jedisClientConfiguration = JedisClientConfiguration.builder();
 //        jedisClientConfiguration.connectTimeout(Duration.ofMillis(6000));//  connection timeout
 //
 //        JedisConnectionFactory factory = new JedisConnectionFactory(redisStandaloneConfiguration, jedisClientConfiguration.build());
 //        return factory;
 //    }
     @Bean
     public RedisConnectionFactory redis(){
         JedisConnectionFactory factory = new JedisConnectionFactory();
         factory.setHostName("192.168.205.128");
         factory.setPort(6379);
         return factory;
     }

     @Bean
     public RedisTemplate<String, User> redisTemplate(RedisConnectionFactory redis){
         RedisTemplate<String, User> redisTemplate = new RedisTemplate<>();
         redisTemplate.setConnectionFactory(redis);
         redisTemplate.setKeySerializer(new StringRedisSerializer());
         redisTemplate.setValueSerializer(new Jackson2JsonRedisSerializer<User>(User.class));
         return redisTemplate;
     }

 //    @Bean
 //    public StringRedisTemplate stringRedisTemplate(RedisConnectionFactory redis){
 //        return new StringRedisTemplate(redis);
 //    }
 }
