[英]The method extractAll(String) is undefined for the type ZipFile with zip4j
我正在尝试制作一个解压缩然后解析 xml.zip 中的 xml 文件的程序。 添加 zip4j 的依赖项,这是我的 pom.xml

我的解析器代码:
import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.dataformat.xml.XmlMapper;
import model.Products;
import net.lingala.zip4j.core.ZipFile;
import org.apache.commons.lang3.StringUtils;
import java.util.zip.ZipFile;
import java.io.File;
import java.io.IOException;
import java.nio.charset.StandardCharsets;
import java.nio.file.Files;
import java.nio.file.Paths;
public class Parser {
public static void main(String[] args) throws IOException {
ObjectMapper objectMapper = new XmlMapper();
String source = "C:\\Users\\user\\java_program\\xml.zip";
String destination = "C:\\Users\\user\\java_program\\xml";
ZipFile zipFile = new ZipFile(source);
zipFile.extractAll(destination);
//Reads from XML and converts to POJO
Products products = objectMapper.readValue(
StringUtils.toEncodedString(Files.readAllBytes(Paths.get("C:\\Users\\user\\java_program\\xml\\xml.xml")), StandardCharsets.UTF_8), Products.class);
System.out.println(products);
}
}
程序还是写错:方法extractAll(String) is undefined for type ZipFile
非常感谢任何帮助
您应该导入net.lingala.zip4j.core.ZipFile
而不是java.util.zip.Zipfile
删除行:
import java.util.zip.ZipFile;
并从您的 import 导入 net.lingala.zip4j.core.ZipFile 中删除.core
import net.lingala.zip4j.core.ZipFile;
整个 class:
import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.dataformat.xml.XmlMapper;
import java.io.IOException;
import java.nio.charset.StandardCharsets;
import java.nio.file.Files;
import java.nio.file.Paths;
import model.Products;
import net.lingala.zip4j.ZipFile;
import net.lingala.zip4j.exception.ZipException;
import org.apache.commons.lang3.StringUtils;
public class Parser {
public static void main(String[] args) throws IOException, ZipException {
ObjectMapper objectMapper = new XmlMapper();
String source = "C:\\Users\\user\\java_program\\xml.zip";
String destination = "C:\\Users\\user\\java_program\\xml";
ZipFile zipFile = new ZipFile(source);
zipFile.extractAll(destination);
//Reads from XML and converts to POJO
Products products = objectMapper.readValue(
StringUtils.toEncodedString(Files.readAllBytes(Paths.get("C:\\Users\\user\\java_program\\xml\\xml.xml")), StandardCharsets.UTF_8), Products.class);
System.out.println(products);
}
}
在您的导入中,您正在导入 java.util.Zipfile 所以删除 -
import java.util.zip.ZipFile;
它应该可以工作。
