设置代码如下

ParserConfig.getGlobalInstance().setAutoTypeSupport(true);
log.info("fastjson isAutoType: {}",ParserConfig.getGlobalInstance().isAutoTypeSupport());

启动输出log如下

2018-09-04 21:59:35.225  INFO 11815 --- [           main] c.c.k.f.c.r.c.RedisConfiguration         : fastjson isAutoType: true

依旧报错

请问在springboot2.x版本添加ParserConfig.getGlobalInstance().setAutoTypeSupport(true);代码兼容springboot1.x版本么？

并且我看源码发现在GenericFastJsonRedisSerializer也设置了defaultRedisConfig.setAutoTypeSupport(true)

源码代码如下

public class GenericFastJsonRedisSerializer implements RedisSerializer<Object> {
    private final static ParserConfig defaultRedisConfig = new ParserConfig();
    static { defaultRedisConfig.setAutoTypeSupport(true);}

    @Override
    public byte[] serialize(Object object) throws SerializationException {
        if (object == null) {
            return new byte[0];
        }
        try {
            return JSON.toJSONBytes(object, SerializerFeature.WriteClassName);
        } catch (Exception ex) {
            throw new SerializationException("Could not serialize: " + ex.getMessage(), ex);
        }
    }

    @Override
    public Object deserialize(byte[] bytes) throws SerializationException {
        if (bytes == null || bytes.length == 0) {
            return null;
        }
        try {
            return JSON.parseObject(new String(bytes, IOUtils.UTF8), Object.class, defaultRedisConfig);
        } catch (Exception ex) {
            throw new SerializationException("Could not deserialize: " + ex.getMessage(), ex);
        }
    }
}
