代码如下
/**
* 将Session序列化成String类型
* @param session
* @return
*/
private String serializ(HttpSession session) {
try {
//ByteArrayOutputStream 用于存储序列化的Session对象
ByteArrayOutputStream bos = new ByteArrayOutputStream();
//将Object对象输出成byte数据
ObjectOutputStream out = new ObjectOutputStream(bos);
out.writeObject(session);
//将字节码，编码成String类型数据
return new String(bos.toByteArray(), YssCons.ENCODING);
} catch (Exception e) {
e.printStackTrace();
// throw new RuntimeException("序列化失败");
}
return null;
}
异常如下：
