Recommendation of the framework framework of the codecs commonly used in the Java class library
In Java development, the compilation of the codec is a very important concept that they are used to convert information from one form to another.Editing code plays an important role in network communication, data storage and security transmission.In the Java class library, there are many commonly used codec frames to choose from.This article will introduce several commonly used Java codec frameworks and display their applications through sample code.
一、Apache Commons Codec
Apache Commons Codec is an open source project under the Apache Foundation. It is a powerful compiled codec frame.It provides a large number of codecs, including BASE64, URL editing code, HTML codec, XML codec, and so on.The following is an example code that uses Apache Commons Codec to implement Base64 encoding and decoding:
import org.apache.commons.codec.binary.Base64;
public class ApacheCommonsCodecExample {
public static void main(String[] args) {
String originalText = "Hello, World!";
// base64 encoding
byte[] encodedBytes = Base64.encodeBase64(originalText.getBytes());
String encodedText = new String(encodedBytes);
System.out.println ("Base64 encoded text:" + Encodedtext);
// base64 decoding
byte[] decodedBytes = Base64.decodeBase64(encodedBytes);
String decodedText = new String(decodedBytes);
System.out.println ("Base64 decoding text:" + decodedtext);
}
}
Second, Google Guava
Google Guava is a Java class library of Google open source, which provides many practical codec tools.These include Base64, URL compilation coders, HTML codecs, and so on.The following is an example code that uses Google Guava to implement URL encoding and decoding:
import com.google.common.net.UrlEscapers;
public class GoogleGuavaExample {
public static void main(String[] args) {
String url = "https://www.example.com/ path/file name.txt";
// url encoding
String encodedUrl = UrlEscapers.urlFragmentEscaper().escape(url);
System.out.println (the address after encoded: " + Encodedurl);
// url decoding
String decodedUrl = UrlEscapers.urlFragmentEscaper().unescape(encodedUrl);
System.out.println ("URL decoding address:" + decodedurl);
}
}
3. Java SE comes with editing codeware
Java SE comes with some codecs, such as Base64 codecs and URL codecs.Here are examples of Base64 encoding and decoding using Java SE's own: 64 encoding and decoding::
import java.util.Base64;
public class JavaSEExample {
public static void main(String[] args) {
String originalText = "Hello, World!";
// base64 encoding
String encodedText = Base64.getEncoder().encodeToString(originalText.getBytes());
System.out.println ("Base64 encoded text:" + Encodedtext);
// base64 decoding
byte[] decodedBytes = Base64.getDecoder().decode(encodedText);
String decodedText = new String(decodedBytes);
System.out.println ("Base64 decoding text:" + decodedtext);
}
}
Summarize:
In the development of Java, the use of codecs is very common, so it is very important to choose a stable and powerful codec frame framework.This article introduces several commonly used Java codec frameworks, including Apache Commons Codec, Google Guava and Java SE's own codecs.Through these frameworks, we can easily achieve various coding and decoding operations to improve development efficiency.I hope this article can help you!
