What is Serialversionuid?

Equivalent to Java class * * *. Primarily for version control.

The Serialversionuid effect is to maintain version compatibility when serializing, that is, deserialization still preserves the uniqueness of the object when the version is upgraded.

There are two ways to build:

One is the default 1L, for example: private static final long serialversionuid = 1L;

One is to generate a 64-bit hash field based on the class name, interface name, member method, and property, for example:

Private static final long serialversionuid = XXXXL;

14 Complete should be <a href= "#" target= "_blank" ></a> meaning to open a hyperlink in a new page window

A button to make the start U disk when the failure of what happened? Today you start a small series to analyze the cause and solution of the failure to make the startup u disk!

As shown: Failed to make start U disk for one click!

What is the cause of the production failure? So how do we fix it? Slowly look down, you start small series with everyone detailed way!

Causes for the failure of one-click Production startup U disk:

Cause one: The files inside the U disk are running or opening;

Solution one: The U disk inside is running or open the file closed after the production can!

Reason two: Security software blocking is caused;

Solution Two: Please make sure to close all safety-related software before making U-disk Startup Disk!

Reason three: Poor USB transmission performance caused;

Solution Three: Try a different USB jack, it is recommended to insert the U disk into the computer chassis behind the USB socket!

Cause four: U disk's own quality problems caused;

Solution Four: Change a U-disk make a try!

Reason five: computer system problems caused;

Resolution Five: Replace a computer reinstall U start re-production!

For:

Request.getcontextpath () should be the name of the project, if the item is the root directory, then get a "", i.e. empty note string, if the item is ABC, <%=request.getcontextpath ()% >/will get ABC /, the server-side path is automatically added
