获取图片大小 java

一、从正文中获取图片并找出满足大小需求的图片

二、代码： 首次写使用了下面这种方式，如有其它方式还请大家赐教

package com.fang.dbtest;

import java.awt.image.BufferedImage;
import java.net.URL;
import java.util.ArrayList;
import java.util.Iterator;
import java.util.List;
import java.util.regex.Matcher;
import java.util.regex.Pattern;

import javax.imageio.ImageIO;

public class Tests {
	// 获取img 获取 src
	@SuppressWarnings("unused")
	public static List<String> replacestyle(String content) {
		List<String> list = new ArrayList<String>();
		List<String> scrlist = null;
		// 获取img 标签的正则
		String img = "<img\\s+([^>]+)\\s*>";
		// 获取 img标签中的src
		String r = "src=\"(.*?)\"";
		// 获取 img 中的style 样式
		String style = "style=\"(.*?)\"";
		Pattern p = Pattern.compile(img);
		// 获取匹配
		Matcher ma = p.matcher(content);
		while (ma.find()) {
			String imgtag = ma.group();
			// System.out.println(imgtag);
			// 再从这个获取的img标签中获取src
			Pattern pp = Pattern.compile(r);
			Matcher mma = pp.matcher(imgtag);
			if (mma.find()) {
				// 获取src
				String src = mma.group();
				// 获取地址
				src = src.substring(5, src.length() - 1);
				// System.out.println(src);
				list.add(src);
			}
		}
		scrlist = getImgSize(list);
		return scrlist;
	}

	// 获取图片大小
	public static List<String> getImgSize(List<String> list) {
		BufferedImage sourceImg = null;
		List<String> srclist = new ArrayList<String>();
		try {
			if (null != list && list.size() > 0) {
				for (int i = 0; i < list.size(); i++) {
					String src = list.get(i);
					URL url = new URL(src);
					// 根据url 获取BufferImage 对象
					sourceImg = ImageIO.read(url);
					// 调用bufferimage 对象的两个方法获取图片宽度高度
					Integer w = Integer.valueOf(sourceImg.getWidth());
					Integer h = Integer.valueOf(sourceImg.getHeight());
					System.out.println("图片宽：" + w + "\n图片高：" + h);
					if (w > 100 && h > 50) {
						srclist.add(src);
					}
				}
			}

		} catch (Exception e) {
			e.printStackTrace();
		}
		return srclist;
	}

	public static void main(String[] args) {
		String content = "<img src=\"http://imgs.soufun.com/news/2014_11/26/1416965084854.jpg\" style=\"heith:8px;width:10px\"> />";
		// returnContent(content);
		List<String> src = replacestyle(content);
		for (Iterator<String> it = src.iterator(); it.hasNext();) {
			String imgsrc = it.next();
			System.out.println(imgsrc);
		}
	}
}
