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.
最佳答案
I’m running into this situation where for some reason Spring is trying to serialize service implementation classes.
spring不要尝试序列化实现.
你做的时候看起来很精简
memcachedClient.set(userId,userSessions);
它期望Serializable对象,但userSessions不是.
Set不可序列化,并键入您获得的类型
(Set) memcachedClient.get(userId);
未序列化为.检查是否可以将memcachedClient.get(userId)强制转换为可序列化的东西,如HashSets或TreeSet ….
最糟糕的是你可以尝试但是你可能会得到CastException
memcachedClient.set(userId,(Serializable)userSessions);
你可以迭代set并做一个简单的检查：
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;
}
