JannoCessor framework detailed explanation: simple, efficient and flexible Java class library processing tool
Introduction:
JannoCessor is a simple, efficient and flexible Java class library processing tool that helps developers handle the annotation in the Java code.This framework provides a convenient way to make annotations, allowing developers to easily process and operate the annotation information in the class library.
Features of JannoCessor framework:
1. Simple and easy -to -use: JannoCessor provides simple APIs, so that developers can easily process the annotation information.By using JannoCessor, developers can simplify complex annotations to process logic and reduce code.
2. High -efficiency processing: JannoCessor uses high -efficiency annotation processing strategies, which can process the annotation during the compilation period to improve the operating efficiency of the program.At the same time, JannoCessor also supports incremental compilation to quickly process a large amount of annotation information.
3. Flexible configuration: JannoCessor provides a wealth of configuration options, so that developers can flexibly configure the annotation logic according to their own needs.Developers can define their own annotation processing rules through configuration files or annotations.
Example of JannoCessor:
The following is a simple example, demonstrating how to use JannoCessor to process the annotation information:
import com.github.jannocessor.parser.AnnotationProcessor;
import com.github.jannocessor.parser.AnnotationProcessorFactory;
import com.github.jannocessor.parser.ElementParser;
import com.github.jannocessor.parser.ElementRepresentation;
import java.util.List;
public class MyAnnotationProcessorFactory implements AnnotationProcessorFactory {
@Override
public AnnotationProcessor create() {
return new MyAnnotationProcessor();
}
}
public class MyAnnotationProcessor extends ElementParser {
@Override
protected void process(ElementRepresentation element, List<String> annotations) {
// Treat the annotation information here
for (String annotation : annotations) {
System.out.println ("Find the annotation:" + Annotation);
}
}
}
It can be seen that in the above code, we first implemented the `AnnotationProcessorFactory` interface, and covered the` Create` method to create our own annotation processor.Then, we defined the `myannotationProcessor` class and inherited the` ElementParser` class.In the `process` method, we can process the annotation information. Here we simply print the annotations found.
When using JannoCessor, we only need to register the custom annotation processor into the compiler:
import com.github.jannocessor.parser.AnnotationProcessorRegistry;
public class Main {
public static void main(String[] args) {
AnnotationProcessorRegistry.registerAnnotationProcessorFactory(new MyAnnotationProcessorFactory());
}
}
In the above code, we use the `annotationProcessorRegistry` class to register our annotation processor into the compiler.Then, when we compile the Java code, JannoCessor will automatically call our annotation processor to process the annotation information.
Summarize:
The JannoCessor framework is a simple, efficient and flexible Java -class library processing tool that can help developers easily handle annotations in the Java code.By using JannoCessor, developers can simplify complex annotation processing logic and improve the operating efficiency of the program.If you need to process the annotation information in the Java code, the JannoCessor framework is a choice worth considering.
