What is token: It is a token that is randomly unpredictable.Why you need to use Token:1 to prevent duplicate submissions of forms2: To prevent cross-site request forgeryToken's use flow is: first generate a random token value on the server side and save it on the server side, then pass the token value to the client during the request process.

It is also used to define a class of XML files.Typically, data of a particular meaning cannot be clearly described by a system-preset structure (type).The XML Schema specification declares that you can restrict (restriction) simple types by

cascading annotations (if the current property is a JavaBean, the fields inside the bean are also validated)Note: When the controller layer method receives parameters, the @Valid annotations are used to indicate that the parameters of the current method need to be validatedEach validation note can be added with the message property, prompting the user when the validation failsExample:// Verify Mailbox@Emai

For a primary data, we not only verify a certain field for a lot of time, but also verify multiple fields for more time, at this time, we can add these single nodes to a group, and we can just execute the group. ADD child Name: Identity Verification Group Add each verification to the group Now we can use the created group for data verification. Error Message

Say Business First,In the Flatmap phase, the current indicator will be in Redis to verify whether the data is a new user, if it is a new user, then statistics, statistics will add the new user to our Redis container ...This business is actually very simple ... But the pit itself is, flatmap after the RDD, will be used by two different action ...And then... I have found that the second action is never a new user in statistics .....Don't you know the re

Data validation is an integral part of project development, user login, password verification needs, of course, the first thing to do is to get the user input content, and then to verify the content, generally read from the database and then check, if the error will display the message, the correct access to the user's main interface. Here's a simple little example to illustrate the next step: 1, the inde

Table data verification is often boring and unavoidable.If the following form has only two input boxes and a confirmation button, what do we need to do normally? 1. If a non-numeric string is entered in the age input box and the input box loses focus, the following error message should be immediately prompted. 2. If the content of the error message changes, you may need to modify the overall uidesign (for example, it is displayed below the input box)

The following small series to take an example to explain in detail: This example requires that the language score above 120 points be highlighted in the red circle.
