The best practice in the development of the T Rex framework in the development of the Java library
introduction:
T Rex is a lightweight Java framework that is specially used to quickly develop reuse -available libraries.It provides a set of tools and agreement to help developers standardize and simplify the development process of the Java class library.This article will introduce the best practice of the T Rex framework in the development of Java libraries, including project structure, naming specifications, abnormal processing, documentation, etc.
1. Project structure
In terms of project structure, the best practice using the T Rex framework is to use standard Maven or Gradle project structures.Place the category code in the SRC/main/java directory and organize it with the appropriate package name.At the same time, the unit test code is placed in the SRC/test/java directory to ensure the quality and stability of the class library.
Example:
- my-library
- src
- main
- java
- com
- example
- mylibrary
- MyLibraryClass.java
- test
- java
- com
- example
- mylibrary
- MyLibraryClassTest.java
2. Name specification
The T Rex framework encourages developers to use semantic naming specifications to improve the readability and maintenance of code.In terms of class and method naming, it is recommended to use clear and concise English words or phrases, and follow the hump naming method.In addition, in order to reduce naming conflicts, it is recommended to add the abbreviation of the class library before the name or method name.
Example:
package com.example.mylibrary;
public class MyLibraryUtils {
public static void convertToSnakeCase(String inputString) {
// Implementation
}
}
Third, abnormal treatment
When dealing with abnormalities, the T Rex framework recommends using the standard abnormal or custom abnormal class of Java to pass the abnormal information.The exception information returned to the caller should be clear and clear to make debugging and error processing.At the same time, abnormalities should be avoided in the class library, but the abnormalities should be passed to the caller, and the caller decides how to deal with the abnormal situation.
Example:
package com.example.mylibrary;
public class MyLibraryUtils {
public static void readFile(String filePath) throws FileNotFoundException, IOException {
// Implementation
}
}
Fourth, documentation
A good document is an important part of a good library.The T Rex framework provides a set of annotation labels to generate library documents.Developers should make full use of these annotation tags to describe the class, methods, parameters, return values, etc., and provide example code and usage description.This makes it easier for users to understand and use this type of library.
Example:
package com.example.mylibrary;
/**
* This is an example document comments.
*
* @since 1.0.0
*/
public class MyLibraryUtils {
/**
* Convert the input string to a snake -shaped naming method.
*
* @param InputString string
* @Return converted string
* @throws illegalargumentexception If the input string is empty
* @since 1.0.0
*/
public static String convertToSnakeCase(String inputString) throws IllegalArgumentException {
// Implementation
}
}
in conclusion:
By following the best practice of the above T Rex framework, developers can better use the framework to develop the reusable Java class library.Good project structure, semantic naming, reasonable abnormal processing and detailed documents can improve the quality and maintenance of the class library, and also facilitate other developers to contribute and participate in the contribution.It is hoped that this article can help developers using the TREX framework for the development of the Java library.
