Steps to Configure Java Barcode SDK with Maven

  1. Install Maven.
  2. Create a new Maven project via the command line:
mvn archetype:generate -DgroupId=com.dynamsoft -DartifactId=test -DarchetypeArtifactId=maven-archetype-quickstart -DarchetypeVersion=1.4 -DinteractiveMode=false
<dependencies>
<dependency>
<groupId>com.dynamsoft</groupId>
<artifactId>dbr</artifactId>
<version>9.0.0</version>
</dependency>
</dependencies>
<repositories>
<repository>
<id>dbr</id>
<url>https://download2.dynamsoft.com/maven/dbr/jar</url>
</repository>
</repositories>
mvn package
java -cp target/test-1.0-SNAPSHOT.jar com.dynamsoft.App

Maven Configuration in Visual Studio Code

  1. Install the Maven extension:
{
"version": "0.2.0",
"configurations": [
{
"type": "java",
"name": "Debug (Launch) - Current File",
"request": "launch",
"mainClass": "${file}",
"args": "images/AllSupportedBarcodeTypes.png"
},
{
"type": "java",
"name": "Debug (Launch)-App<test>",
"request": "launch",
"mainClass": "com.dynamsoft.App",
"projectName": "test",
"args": "images/AllSupportedBarcodeTypes.png"
}
]
}

Implementing Multiple Barcode and QR Code Scanning in Java

import com.dynamsoft.dbr.*;
BarcodeReader br = null;
try {
BarcodeReader.initLicense("LICENSE-KEY");
br = new BarcodeReader();
} catch (Exception e) {
System.out.println(e);
return;
}
BufferedImage img = null;
try {
img = ImageIO.read(new File(pszImageFile));
TextResult[] results = br.decodeBufferedImage(img, "");

} catch (IOException e) {
System.out.println(e);
}
TextResult[] results = br.decodeFile(pszImageFile, "");
TextResult[] results = br.decodeFileInMemory(Files.readAllBytes(new File(pszImageFile).toPath()), "");
if (results != null && results.length > 0) {
String pszTemp = null;
iIndex = 0;
for (TextResult result : results) {
iIndex++;
pszTemp = String.format(" Barcode %d:", iIndex);
System.out.println(pszTemp);
pszTemp = String.format(" Page: %d", result.localizationResult.pageNumber + 1);
System.out.println(pszTemp);
if (result.barcodeFormat != 0) {
pszTemp = " Type: " + result.barcodeFormatString;
} else {
pszTemp = " Type: " + result.barcodeFormatString_2;
}
System.out.println(pszTemp);
pszTemp = " Value: " + result.barcodeText;
System.out.println(pszTemp);

pszTemp = String.format(" Region points: {(%d,%d),(%d,%d),(%d,%d),(%d,%d)}",
result.localizationResult.resultPoints[0].x, result.localizationResult.resultPoints[0].y,
result.localizationResult.resultPoints[1].x, result.localizationResult.resultPoints[1].y,
result.localizationResult.resultPoints[2].x, result.localizationResult.resultPoints[2].y,
result.localizationResult.resultPoints[3].x, result.localizationResult.resultPoints[3].y);

System.out.println(pszTemp);
System.out.println();
}
}
ThreadPoolExecutor executor = (ThreadPoolExecutor) Executors.newFixedThreadPool(10);

for (int i = 1; i <= 1000; i++)
{
executor.execute(new Runnable(){

@Override
public void run() {
App test = new App();
test.decodefile(filename);
try {
Thread.sleep(200);
} catch (InterruptedException e) {
System.out.println(e);
}
}
});
}
executor.shutdown();

How to Build and Run Java Barcode and QR Code Reader

<plugin>
<artifactId>maven-assembly-plugin</artifactId>
<configuration>
<descriptorRefs>
<descriptorRef>jar-with-dependencies</descriptorRef>
</descriptorRefs>
</configuration>
</plugin>
mvn clean install assembly:assembly
java -cp target/test-1.0-SNAPSHOT-jar-with-dependencies.jar com.dynamsoft.App images/AllSupportedBarcodeTypes.png

How to Deploy and Run Java Application Using Docker

  1. Create a Dockerfile:
FROM openjdk:11-stretch
COPY images/AllSupportedBarcodeTypes.png AllSupportedBarcodeTypes.png
COPY target/test-1.0-SNAPSHOT-jar-with-dependencies.jar test-1.0-SNAPSHOT-jar-with-dependencies.jar
CMD java -cp test-1.0-SNAPSHOT-jar-with-dependencies.jar com.dynamsoft.App AllSupportedBarcodeTypes.png
docker rmi dynamsoft/barcode-reader -f
docker build -t dynamsoft/barcode-reader -f Dockerfile .
docker run -it dynamsoft/barcode-reader
