一.redis的安装

=查看reids列表安装博文

二.spring整合redis

1.pom文件依赖引用

sb2.x以后redis等数据处理组件都封装到 spring data 工程里了

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

2.application配置

----可根据需要配置更多先关参数

# REDIS (RedisProperties)
    # Redis数据库索引（默认为0）
    spring.redis.database=0
    # Redis服务器地址
    spring.redis.host=127.0.0.1
    # Redis服务器连接端口
    spring.redis.port=6379
    # 连接池最大连接数（使用负值表示没有限制）
    spring.redis.pool.max-active=8
    # 连接池最大阻塞等待时间（使用负值表示没有限制）
    spring.redis.pool.max-wait=-1
    # 连接池中的最大空闲连接
    spring.redis.pool.max-idle=8
    # 连接池中的最小空闲连接
    spring.redis.pool.min-idle=0
    # 连接超时时间（毫秒）
    spring.redis.timeout=0

3.redisConfig配置

package com.spf.demo.config;
    
    import com.fasterxml.jackson.annotation.JsonAutoDetect;
    import com.fasterxml.jackson.annotation.PropertyAccessor;
    import com.fasterxml.jackson.databind.ObjectMapper;
    import org.springframework.cache.CacheManager;
    import org.springframework.cache.annotation.CachingConfigurerSupport;
    import org.springframework.cache.annotation.EnableCaching;
    import org.springframework.context.annotation.Bean;
    import org.springframework.context.annotation.Configuration;
    import org.springframework.data.redis.cache.RedisCacheManager;
    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 org.springframework.data.redis.serializer.StringRedisSerializer;
    
    /**
     * @auther kongxianwei
     * @date ${DATAE} 18:18
     * @description
     */
    @Configuration
    @EnableCaching
    public class RedisConfig extends CachingConfigurerSupport {
    
        @Bean
        public RedisTemplate<Object, Object> redisTemplate(RedisConnectionFactory connectionFactory) {
            RedisTemplate<Object, Object> template = new RedisTemplate<>();
            template.setConnectionFactory(connectionFactory);
            //使用Jackson2JsonRedisSerializer来序列化和反序列化redis的value值
            Jackson2JsonRedisSerializer serializer = new Jackson2JsonRedisSerializer(Object.class);
            ObjectMapper mapper = new ObjectMapper();
            mapper.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
            mapper.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL);
            serializer.setObjectMapper(mapper);
            template.setValueSerializer(serializer);
            //使用StringRedisSerializer来序列化和反序列化redis的key值
            template.setKeySerializer(new StringRedisSerializer());
            template.afterPropertiesSet();
            return template;
        }
    
    }

4.测试服务类

package com.spf.demo.app;
    
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.data.redis.core.RedisTemplate;
    import org.springframework.data.redis.core.ValueOperations;
    import org.springframework.stereotype.Controller;
    import org.springframework.ui.ModelMap;
    import org.springframework.web.bind.annotation.RequestMapping;
    
    import java.util.concurrent.TimeUnit;
    
    
    /**
     * Hello world!
     */
    @Controller
    @RequestMapping("/app")
    public class App {
    
        @Autowired
        RedisTemplate redisTemplate ;
    
    
        @RequestMapping("/thymeleaf")
        public String thymeleaf(ModelMap map) {
            ValueOperations<String, String> ops = redisTemplate.opsForValue();
    
                ops.set("user","zhangsan",1, TimeUnit.MINUTES);
                ops.set("title","redis测试不带时间的测试");
    
    
                map.addAttribute("title",ops.get("title"));
                map.addAttribute("user",ops.get("user"));
            return "login";
        }
    
    }
