NextInputs Framework: Comprehensive introduction and application of Java class libraries
Overview:
NextInputs is a lightweight input verification framework widely used in Java.It provides a simple but powerful way to verify and process various input data, such as user input and network request parameters.The goal of the NextInPuts framework is to help developers write reliable and maintained code to ensure that the application verifies the correctness of various input data, thereby providing a better user experience and data security.
Framework characteristics:
1. Flexible and easy to use: NextInputs provides a set of simple and rich verification rules that can be used to verify different types of input data.Developers can freely combine and customize these rules according to actual needs to meet specific verification requirements.
2. Highly scalability: NEXTINPUTS framework uses modular design. By defining custom verification rules and converters, its functions can be easily expanded.This allows developers to quickly add new verification rules or process logic according to the needs of the application.
3. High performance: The nextInpputs framework is optimized, the execution efficiency is high, and it can also maintain stability and reliability when processing a large amount of input data.
4. Provide rich verification rules: NextInputs provides many commonly used verification rules, such as non -empty, minimum length, maximum length, value range, etc.Developers can choose a rule that suits them according to needs.
Example:
The following is a simple example of using the NextInputs framework, which illustrates how to verify the user's login input:
import com.github.yoojia.next.inputs.*;
public class LoginFormValidator {
public static void main(String[] args) {
InputChecker checker = new InputChecker();
String username = "testUser";
String password = "123456";
// Add verification rules
Checker.add (username, simpleconf.key_not_null, "user name cannot be empty");
Checker.add (password, simpleconf.key_not_null, "password cannot be empty");
Checker.add (password, simpleconf.key_length_range, "password length needs to be between 6-16 characters", 6, 16);
// Start verification
String result = checker.start();
if (result == null) {
System.out.println ("Login Verification Pass");
// Execute the login operation
} else {
System.out.println ("Login verification failed:" + Result);
}
}
}
In the above example, we first created an INPUTCHECKER object, and then added verification rules through the ADD () method.In this example, we use three verification rules: non -air rules (SimpleConf.key_not_null), and the length range of the range (simpleconf.key_length_raange).
Finally, we call the start () method to perform verification.If the input data passes all the verification rules, it returns NULL and indicates that the verification passes.Otherwise, return the error message of the failed verification.
in conclusion:
