springboot集成redis

1,添加依赖

<!-- redis配置 begin -->
        <dependency>
            <groupId>redis.clients</groupId>
            <artifactId>jedis</artifactId>
            <version>2.7.3</version>
        </dependency>
        <dependency>
            <groupId>org.springframework.data</groupId>
            <artifactId>spring-data-redis</artifactId>
            <version>1.7.2.RELEASE</version>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-redis</artifactId>
            <version>RELEASE</version>
        </dependency>
        <!-- redis配置 end -->

2,添加配置信息

#Redis配置信息
# 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  
# Redis服务器连接密码(默认为空)
spring.redis.password=  
# 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,Redis配置类

package org.spring.web.component;
import java.util.Arrays;
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 com.fasterxml.jackson.annotation.JsonAutoDetect;
import com.fasterxml.jackson.annotation.PropertyAccessor;
import com.fasterxml.jackson.databind.ObjectMapper;

/**
 * redis配置类
 */
@Configuration
@EnableCaching
public class RedisConfig extends CachingConfigurerSupport{

    @SuppressWarnings("rawtypes")
    @Bean
    public CacheManager cacheManager(RedisTemplate redisTemplate) {
        RedisCacheManager rcm = new RedisCacheManager(redisTemplate);
        // 多个缓存的名称,目前只定义了一个
        rcm.setCacheNames(Arrays.asList("thisredis"));
        //设置缓存过期时间(秒)
        rcm.setDefaultExpiration(600);
        return rcm;
    }

    @Bean
    public RedisTemplate<String, String> redisTemplate(RedisConnectionFactory factory) {
        StringRedisTemplate template = new StringRedisTemplate(factory);
        Jackson2JsonRedisSerializer jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer(Object.class);
        ObjectMapper om = new ObjectMapper();
        om.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
        om.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL);
        jackson2JsonRedisSerializer.setObjectMapper(om);
        template.setValueSerializer(jackson2JsonRedisSerializer);
        template.afterPropertiesSet();
        return template;
    }

}

该类生成Redis操作类,并注入到容器中。

4,验证

像Redis中存入一个user对象

    @Override
    public String getUser() {
         User user=new User();
         user.setId(22);
         user.setUserName("interview");
         ValueOperations<String, User> operations=redisTemplate.opsForValue();
         operations.set("com.yfli", user);
         operations.set("com.neo.f", user,1,TimeUnit.SECONDS);
         try {
            Thread.sleep(1000);
        } catch (InterruptedException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }        
            //redisTemplate.delete("com.neo.f");
            boolean exists=redisTemplate.hasKey("com.neo.f");
            if(exists){
                System.out.println("exists is true");
            }else{
                System.out.println("exists is false");
            }     
            User redisUser=operations.get("com.yfli");
           return redisUser.toString();
    }

redis大致有5中数据接口,字符串,hash,list,set,storedSet。目前的项目使用redis主要作为缓存。(相关问题:Redis缓存穿透?)
