    }
    // Zone file should not (normally) be changed, so let's make this more difficult
    assertEquals(hasher.hash().asLong(), 6334606028834602490L, "zone-index.properties file contents changed!");
}

Example 95 with Hasher

use of com.google.common.hash.Hasher in project java-chassis by ServiceComb.

the class EdgeSignatureResponseFilter method beforeSendResponse.

@Override
