jcaptcha与jdk兼容问题,验证码黑框问题处理

在使用jcaptcha进行验证码的生成时会遇到验证码黑框的问题,经过字啊网上搜索,最终发现是jdk版本的兼容问题

这是jdk7的写法,jdk8会出现黑框

        //生成背景的大小这里是宽140高45的图片，背景颜色为白色
		BackgroundGenerator backgroundGenerator = new UniColorBackgroundGenerator(new Integer(140), new Integer(45), Color.white);
		// 字体随机生成
		FontGenerator fontGenerator = new RandomFontGenerator(new Integer(30), new Integer(0), fonts);
 
 
		WaterFilter water = new WaterFilter();

		water.setAmplitude(4d);

	ImageDeformation backDef = new ImageDeformationByFilters(
				new ImageFilter[] {});
		ImageDeformation textDef = new ImageDeformationByFilters(

		ImageDeformation postDef = new ImageDeformationByFilters(
				new ImageFilter[] { water });
	   WordToImage cwti = new      DeformedComposedWordToImage(fontGenerator,backgroundGenerator,textPaster, backDef, textDef, postDef);
 
		
 
    	this.addFactory(new GimpyFactory(wgen, cwti));
    
    }  
  
} 

这是jdk7,jdk8两者兼容的写法
