添加JAI爲wildfly模塊

我有一個java bean的項目，我需要使用JAI，所以我添加一個Maven depedendency添加JAI爲wildfly模塊

<dependency> 
    <groupId>com.github.jai-imageio</groupId> 
    <artifactId>jai-imageio-core</artifactId> 
    <version>1.3.1</version> 
</dependency>

我嘗試添加新模塊wildfly 9喜歡

模塊。 XML

<?xml version="1.0" encoding="UTF-8"?> 

<module xmlns="urn:jboss:module:1.3" name="com.github.jaiimageio"> 
    <resources> 
     <resource-root path="jai-imageio-core-1.3.1.jar"/> 
    </resources> 
</module>

然後我從mvnrepo 添加一個罐子，罐子放+ module.xml在

wildfly-9.0.2.Final \模塊\ SYSTEM \層\基地\ COM \ github上\ jaiimageio \主

在我的Java項目

然後

JBoss的部署，structure.xml

<jboss-deployment-structure> 
    <deployment> 
     <dependencies> 
      <module name="org.jboss.ejb3"/> 
      <module name="org.jboss.ws.api"/> 
      <module name="org.apache.cxf"/> 
      <module name="org.jboss.ws.cxf.jbossws-cxf-server"/> 
      <module name="com.github.jaiimageio"/> 
     </dependencies> 
    </deployment> 
</jboss-deployment-structure>

但是，當我試圖打電話給我的java bean我有一個例外

我的代碼：

private void write_tiff() throws IOException 
    { 
     RenderedImage image=javax.imageio.ImageIO.read(new File("C:\\users\\user\\Desktop\\examples\\srts.jpg")); 
     RenderedImage image1=javax.imageio.ImageIO.read(new File("C:\\users\\user\\Desktop\\examples\\passport.jpg")); 

     Iterator<ImageWriter> iterator=ImageIO.getImageWritersByFormatName("TIFF"); 
     System.out.println(iterator.hasNext()); 

     ImageWriter writer=iterator.next(); 
    }

ImageIO.getImageWritersByFormatName（「TIFF」）返回null。

但是，如果我從java應用程序調用此方法，而不是在java bean中，一切都可以。

我試圖chande modulename com.github.jai-imageio，但沒有chandes。

任何人都可以幫助我嗎？

可能的重複[發生在Tiff的getImageWritersByFormatName中。獲取圖像作家]（http://stackoverflow.com/questions/22523644/issue-in-getimagewritersbyformatname-for-tiff-getting-image-writer）。特別注意第二個答案，關於Tomcat –

謝謝Jon，但我已經試過調用scanForPlugins（），沒有結果。此外，我將我的jar添加到wildfly的ext文件夾中，但不幸的是也沒有提供。 –

您是否已將jai-imageio-core-1.3.1.jar添加到jre的lib/ext目錄中？我認爲這就是第一個答案所表明的。 –

我可以解決這個問題而不增加罐子JVM的分機

代碼：

ImageIO.scanForPlugins(); 
ByteArrayOutputStream output_stream=new ByteArrayOutputStream();    
try 
{ 
    ImageOutputStream output = ImageIO.createImageOutputStream(output_stream); 
    ImageWriter writer = new TIFFImageWriterSpi().createWriterInstance(); 
    writer.setOutput(output); 
    writer.prepareWriteSequence(null); 
    writeToSequence(new IIOImage(ImageIO.read(new ByteArrayInputStream(bytes)),null,null),null); 
    writer.endWriteSequence(); 
    writer.dispose();   
    output.flush(); 
    output.close();

POM依賴性：

<dependency> 
    <groupId>com.sun.media</groupId> 
    <artifactId>jai_imageio</artifactId> 
    <version>1.2-pre-dr-b04</version>

module.xml（wildfly \模塊\ SYSTEM \層\ base \ com \ sun \ media \ imageio \ main）
