SCANNIT framework in the Java library use skills
The Scannit framework is a tool to provide scanning function in the Java class library.It can help developers automatically scan the class, methods and fields in the Java class library to provide a more convenient and flexible development experience.This article will introduce the use of the Scannit framework in the Java class library, and explain the complete programming code and related configuration when necessary.
1. Add Scannit dependencies
In your Java project, you first need to add the dependencies of the Scannit framework.You can add the following dependencies in the configuration file of the project construction tool (such as Maven or Gradle):
<!-Maven dependence->
<dependency>
<groupId>com.github.tdurieux</groupId>
<artifactId>scannit</artifactId>
<version>1.1.0</version>
</dependency>
// Gradle dependencies
implementation 'com.github.tdurieux:scannit:1.1.0'
2. Create a scanner object
Create a scanner object in the project to use the Scannit framework function.You can create a scanner object by instantiated `Scanner` class, as shown below:
Scanner scanner = new Scanner();
3. Class in the scanning library
Scan the class in the Java library with the scanner object.You can complete this operation by calling the method of calling `Scanner.scanclasses (...).This method receives a parameter containing the path of the library and returns a list containing scanned class objects.
List<Class<?>> classes = scanner.scanClasses("com.example.library");
4. Scanning method and field
Use the method and field of the scanner object to scan library.You can implement by calling the `Scanner.Scanmethods (...) and` Scanner.Scanfields (...) `method.These methods receive parameters of a class object and specific conditions, and return the corresponding method or field list.
List<Method> methods = scanner.scanMethods(classObj, method -> method.getParameterCount() == 0);
List<Field> fields = scanner.scanFields(classObj, field -> field.getType().equals(String.class));
5. Configure scanner
You can also configure the scanner object to meet specific needs.For example, you can use the `setclasspath (...)` method to set the path of the class library, or use the `setexcludes (...)" method to eliminate specific classes or packages.
scanner.setClasspath("/path/to/library.jar");
scanner.setExcludes(Arrays.asList("com.example.library.ExcludedClass"));
Through the above steps, you can use the Scannit framework in the Java library to achieve the function of automatic scanning class, methods and fields.This can reduce the duplicate work of developers and make your code more flexible and easy to maintain.
I hope this article will help you understand and use the Scannit framework.If you have any questions, you can ask in the comments that I will try my best to answer.
