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srcString 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srcPattern pp = Pattern.compile(r);Matcher mma = pp.matcher(imgtag);if (mma.find()) {// 获取srcString 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);}}}
