springboot2.x+Redis+Fastjson(坑已填),Redis使用Fastjson序列化

• 去除springboot自带Jackson,必须去除,画重点,springboot2.x在引入了spring-boot-starter-data-redis的时候,如果不去除Jackson,即使配置了FastJsonHttpMessageConverter,依然不生效,所以必须去除,但是如果不引入spring-boot-starter-data-redis则不影响,目前不知道原因,就去除了吧

      
          org.springframework.boot
          spring-boot-starter-web
          
              
                  jackson-databind
                  com.fasterxml.jackson.core
              
          
      
      
          com.alibaba
          fastjson
          1.2.60
      
  

• 配置GenericFastJson2JsonRedisSerializer

  package com.fengche.emsa.serializers;
  
  import com.alibaba.fastjson.JSON;
  import com.alibaba.fastjson.parser.ParserConfig;
  import com.alibaba.fastjson.serializer.SerializerFeature;
  import org.springframework.data.redis.serializer.RedisSerializer;
  import org.springframework.data.redis.serializer.SerializationException;
  import org.springframework.lang.Nullable;
  import org.springframework.stereotype.Component;
  
  @Component
  public class GenericFastJson2JsonRedisSerializer implements RedisSerializer
