Solve the problem that CsrfFilter and CsrfWebFilter throws NPE exception when comparing two byte array is equal in low JDK version.
When JDK version is lower than 1.8.0_45,method java.security.MessageDigest#isEqual does not verify whether the two arrays are null.
And the above two class call this method without null judgment.
