spring– 如何确定我的会话尝试序列化的对象？

我最近升级到Spring Security 4.2.3.RELEASE.我也在使用spymemcached v 2.8.4.我遇到了这种情况,由于某些原因,Spring正在尝试序列化服务实现类.我无法弄清楚这是从哪里来的.异常引用的代码行是

Set

带着神秘的错误(“java.io.NotSerializableException：org.mainco.subco.ecom.service.ContractServiceImpl”被埋在里面)……

我如何弄清楚memcache正在尝试序列化的对象,从而弄清楚它是如何引用服务类来序列化的？

这个问题的关键不在于我如何使我的服务类可序列化,但为什么我的会话试图首先序列化它.

int count=0;for(Session session: userSessions ){    log....    boolean isSerializable = checkIfSerializable(session);    count=isSerializable ? count+1 : count;    log }private static boolean checkIfSerializable(Object value) throws illegalaccessexception {    try {        ByteArrayOutputStream bf = new ByteArrayOutputStream();        ObjectOutputStream oos = new ObjectOutputStream(bf);        oos.writeObject(value);        oos.close();        ObjectinputStream ois = new ObjectinputStream(new ByteArrayinputStream(bf.toByteArray()));        Object o = ois.readobject();        return true;    } catch (Exception e) {        System.out.println("----->>>> Not exactly Serializable : " + value);    }        return false;}
