嘗試刪除的原因：

${catalina.home}/work/Catalina/localhost/<app>/SESSION.ser where app is your application. 

並重新啓動。

如果這樣做不起作用或者您每次都選擇不這樣做，請確保您的Dao或其他類如CardBean必須實現java.io.Serializable接口（如果要序列化）（您的堆棧跟蹤表示嘗試將類的實例寫入對象流）。

要序列化的實例以及該實例的對象圖中的所有對象都必須是可序列化的。

從的javadoc，序列化，

Serializability of a class is enabled by the class implementing the java.io.Serializable interface...When traversing a graph, an object may be encountered that does not support the Serializable interface. In this case the NotSerializableException will be thrown and will identify the class of the non-serializable object.
