Alfresco 向图像添加水印

我需要向添加到文件夹（空间）“Images in”的图像添加水印，并将图像移动到空间“Images out”（通过内容规则）

转换器（添加到c:\Alfresco\tomcat\webapps\Alfresco\WEB-INF\classes\com\xyz\：

package com.xyz;

import java.io.InputStream;
import java.io.InputStreamReader;
import java.io.OutputStream;
import java.nio.charset.Charset;
import org.alfresco.error.AlfrescoRuntimeException;
import org.alfresco.repo.content.MimetypeMap;
import org.alfresco.service.cmr.repository.ContentReader;
import org.alfresco.service.cmr.repository.ContentWriter;
import org.alfresco.service.cmr.repository.TransformationOptions;
import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import org.alfresco.repo.content.transform.AbstractContentTransformer2;

import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;


import java.util.Map;

/**
 * Created with IntelliJ IDEA.
 * User: dragan
 */
public class ImageTransformer extends AbstractContentTransformer2 {
    private static final Log logger = LogFactory.getLog(ImageTransformer.class);

    static {
        logger.info("Created ImageTransformer");
    }

    protected void transformInternal(ContentReader contentReader, ContentWriter contentWriter, TransformationOptions transformationOptions) throws Exception {
        logger.info("transformInternal" );
        // put some water on the image
    }

    public boolean isTransformable(String sourceMimetype, String targetMimetype, TransformationOptions transformationOptions) {
        logger.info("getReliability - sourceMimetype :" + sourceMimetype + " targetMimetype: " + targetMimetype );
        if (sourceMimetype.equals(MimetypeMap.MIMETYPE_IMAGE_JPEG)
                || sourceMimetype.equals(MimetypeMap.MIMETYPE_IMAGE_PNG)
                || sourceMimetype.equals(MimetypeMap.MIMETYPE_IMAGE_GIF) &&
                targetMimetype.equals(MimetypeMap.MIMETYPE_IMAGE_JPEG)) {
            return true;
        } else {
            return false;
        }
    }
}

根据档案 content-services-context.xml被添加到c:\Alfresco\tomcat\shared\classes\Alfresco\extension\

            </bean>
         </list>
      </property>
   </bean>
</beans>

图像/jpeg
图像/jpeg
图像/png
图像/jpeg
图像/gif
图像/jpeg

当Alfresco服务器重新启动时，没有logger.info（“创建的ImageTransformer”）；

是否可以实现此过程？如何从内容规则调用图像转换器？

您是否尝试使用webscript而不是Java：
