## 1.导入依赖 ##

<dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-data-redis</artifactId>
     </dependency>

## 2.修改`application.yml` ##

server:
      port: 8000
    
    spring:
      profiles:
        active: dev
      application:
        name: ml-student
      datasource:
        username: root
        password: 123456
        driver-class-name: com.mysql.jdbc.Driver
        url: jdbc:mysql://localhost:3306/ml?characterEncoding=UTF8&serverTimezone=UTC
      redis:
        host: 192.168.229.128
        password: 123456
        port: 6379
    
    
    
    mybatis:
      mapper-locations: classpath:mapper/**/*.xml
    #驼峰匹配
      configuration:
        map-underscore-to-camel-case: true
        #    日志输出sql
        logImpl: org.apache.ibatis.logging.stdout.StdOutImpl
    
    eureka:
      client:
        service-url:
          defaultZone: http://localhost:8761/eureka/

## 3. 配置redisTemplate ##

import com.fasterxml.jackson.annotation.JsonAutoDetect;
    import com.fasterxml.jackson.annotation.PropertyAccessor;
    import com.fasterxml.jackson.databind.ObjectMapper;
    import org.springframework.boot.autoconfigure.condition.ConditionalOnMissingBean;
    import org.springframework.context.annotation.Bean;
    import org.springframework.context.annotation.Configuration;
    import org.springframework.data.redis.connection.RedisConnectionFactory;
    import org.springframework.data.redis.core.RedisTemplate;
    import org.springframework.data.redis.core.StringRedisTemplate;
    import org.springframework.data.redis.serializer.Jackson2JsonRedisSerializer;
    
    import java.net.UnknownHostException;
    
    
    @Configuration
    public class RedisTemplateConfig { 
    
        @Bean
        @ConditionalOnMissingBean(name = "redisTemplate")
        public RedisTemplate<String, Object> redisTemplate(
                RedisConnectionFactory redisConnectionFactory)
                throws UnknownHostException { 
    
            Jackson2JsonRedisSerializer<Object> jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer<Object>(Object.class);
            ObjectMapper om = new ObjectMapper();
            om.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
            om.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL);
            jackson2JsonRedisSerializer.setObjectMapper(om);
    
            RedisTemplate<String, Object> template = new RedisTemplate<String, Object>();
            template.setConnectionFactory(redisConnectionFactory);
            template.setKeySerializer(jackson2JsonRedisSerializer);
            template.setValueSerializer(jackson2JsonRedisSerializer);
            template.setHashKeySerializer(jackson2JsonRedisSerializer);
            template.setHashValueSerializer(jackson2JsonRedisSerializer);
            template.afterPropertiesSet();
            return template;
        }
    
        @Bean
        @ConditionalOnMissingBean(StringRedisTemplate.class)
        public StringRedisTemplate stringRedisTemplate(
                RedisConnectionFactory redisConnectionFactory)
                throws UnknownHostException { 
            StringRedisTemplate template = new StringRedisTemplate();
            template.setConnectionFactory(redisConnectionFactory);
            return template;
        }
    
    }

## 4.将`RedisTemplate`注入 ##

@Autowired
    private RedisTemplate redisTemplate;

## 5.redisTemplate常用方法 ##

[**redisTemplate常用api**][redisTemplate_api]

## 6.测试 ##

redisTemplate.opsForValue().set("Key","hello");
    Object key = redisTemplate.opsForValue().get("Key");
    System.out.println(key);
