When using Shiro to cache user identity information: Java.io.NotSerializableException:org.apache.shiro.util.SimpleByteSource

Recently in the use of Shiro cache user identity information, reported that Simplebytesource can not be serialized, follow-up source A look, originally this class does not implement the serialization interface, but I in the cache identity information implementation and use this class, workaround: Rewrite a class, Imitate the Simplebytesoure class and write your own class. And the implementation of the serialization interface can be.

Within the realm of your own implementation, call the following:

1 New New Shirobytesource (User.getsalt ()), GetName ());

The previous wording was:

1 New New Simplebytesource (User.getsalt ()), GetName ());

Then we can solve the problem.
