Javaparser是一个用Java编写的解析器库,它可以用来解析、检查、修改和生成Java源代码。下面是使用Javaparser的简单示例:
<dependency>
<groupId>com.github.javaparser</groupId>
<artifactId>javaparser-core</artifactId>
<version>3.28.0</version>
</dependency>
HelloWorld.java
:public class HelloWorld {
public static void main(String[] args) {
System.out.println("Hello, World!");
}
}
import com.github.javaparser.JavaParser;
import com.github.javaparser.ast.CompilationUnit;
import com.github.javaparser.ast.body.ClassOrInterfaceDeclaration;
import com.github.javaparser.ast.body.MethodDeclaration;
import java.io.FileInputStream;
public class Main {
public static void main(String[] args) throws Exception {
FileInputStream in = new FileInputStream("HelloWorld.java");
CompilationUnit cu = JavaParser.parse(in);
cu.findAll(ClassOrInterfaceDeclaration.class).forEach(clazz -> {
System.out.println("Class name: " + clazz.getName());
clazz.findAll(MethodDeclaration.class).forEach(method -> {
System.out.println("Method name: " + method.getName());
});
});
}
}
Class name: HelloWorld
Method name: main
这就是使用Javaparser来解析Java源代码文件的简单示例。您可以进一步探索Javaparser的功能,以进行更复杂的源代码分析和修改。
