【spring boot】2.0 整合spring-session,自定义序列化session存储到redis

一·引入jar包

   org.springframework.boot
   spring-boot-starter-parent
   2.0.0.RELEASE
    

   org.springframework.session
   spring-session-data-redis
   2.0.2.RELEASE

   org.springframework.boot
   spring-boot-starter-data-redis

二·编写代码

1·自定义序列化接口 ，实现RedisSerializer接口

import com.alibaba.fastjson.JSON;
import com.alibaba.fastjson.serializer.SerializerFeature;
import org.springframework.data.redis.serializer.RedisSerializer;
import org.springframework.data.redis.serializer.SerializationException;

import java.nio.charset.Charset;

/**
 * 说明:自定义redis序列化方式
 *
 * @author WangBin
 * @version V1.0
 * @since 2018.03.22
 */
public class FastJsonRedisSerializer implements RedisSerializer {
    
    public static final Charset DEFAULT_CHARSET = Charset.forName("UTF-8");

    private Class clazz;

    public FastJsonRedisSerializer(Class clazz) {
        super();
        this.clazz = clazz;
    }
    
    @Override
    public byte[] serialize(T t) throws SerializationException {
        if (t == null) {
            return new byte[0];
        }
        return JSON.toJSONString(t, SerializerFeature.WriteClassName).getBytes(DEFAULT_CHARSET);
    }

    @Override
    public T deserialize(byte[] bytes) throws SerializationException {
        if (bytes == null || bytes.length <= 0) {
            return null;
        }
        String str = new String(bytes, DEFAULT_CHARSET);
        return JSON.parseObject(str, clazz);
    }
}

2·redis配置 

import org.springframework.cache.annotation.CachingConfigurerSupport;
import org.springframework.cache.annotation.EnableCaching;
import org.springframework.cache.interceptor.KeyGenerator;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.redis.cache.RedisCacheConfiguration;
import org.springframework.data.redis.connection.RedisConnectionFactory;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.serializer.RedisSerializationContext;
import org.springframework.data.redis.serializer.StringRedisSerializer;
import org.springframework.session.SessionRepository;
import org.springframework.session.data.redis.RedisOperationsSessionRepository;

import java.time.Duration;

/**
 *  redis 配置
 *
 * @author WangBin
 * @version V1.0
 * @date 2017.12.05
 */
@Configuration
@EnableCaching
public class RedisConfig extends CachingConfigurerSupport {

    @Bean
    @Override
    public KeyGenerator keyGenerator() {
        return (target, method, params) -> {
            StringBuilder sb = new StringBuilder();
            sb.append(target.getClass().getName());
            sb.append(method.getName());
            for (Object obj : params) {
                sb.append(obj.toString());
            }
            return sb.toString();
        };
    }

    /**
     *  设置 redisTemplate 序列化方式
     * @param factory
     * @return
     */
    @Bean
    public RedisTemplate redisTemplate(RedisConnectionFactory factory) {
        RedisTemplate redisTemplate = new RedisTemplate<>();
        redisTemplate.setConnectionFactory(factory);
        // 设置值（value）的序列化采用FastJsonRedisSerializer。
        FastJsonRedisSerializer
