如何在JAR文件中搜索字符串

jar -tf your-jar-file.jar | grep -i "search-string"

import java.io.BufferedReader;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.util.jar.JarEntry;
import java.util.jar.JarFile;

public class JarSearch {
    public static void main(String[] args) throws Exception {
        String jarFilePath = "your-jar-file.jar";
        String searchString = "search-string";

        try (JarFile jarFile = new JarFile(jarFilePath)) {
            for (Enumeration<JarEntry> entries = jarFile.entries(); entries.hasMoreElements();) {
                JarEntry entry = entries.nextElement();
                if (!entry.isDirectory()) {
                    try (InputStream input = jarFile.getInputStream(entry)) {
                        BufferedReader reader = new BufferedReader(new InputStreamReader(input));
                        String line;
                        int lineNumber = 0;
                        while ((line = reader.readLine()) != null) {
                            lineNumber++;
                            if (line.contains(searchString)) {
                                System.out.println("Found in " + entry.getName() + " line " + lineNumber + ": " + line);
                            }
                        }
                    }
                }
            }
        }
    }
}
