Deprecated Classes

Class and Description
com.alibaba.fastjson.util.AntiCollisionHashMap

com.alibaba.fastjson.support.spring.FastJsonHttpMessageConverter4
com.alibaba.fastjson.support.spring.FastJsonpHttpMessageConverter4
com.alibaba.fastjson.support.spring.FastJsonpResponseBodyAdvice
org.apache.commons.io.FileCleaner Use FileCleaningTracker
org.apache.commons.io.FileSystemUtils As of 2.6 deprecated without replacement. Use equivalent methods in FileStore instead, e.g. Files.getFileStore(Paths.get("/home")).getUsableSpace() or iterate over FileSystems.getDefault().getFileStores()
com.alibaba.fastjson.serializer.JSONSerializerMap
com.alibaba.fastjson.support.spring.MappingFastJsonValue
com.alibaba.fastjson.util.ThreadLocalCache
