压缩Html HtmlCompressor

一般对于网页的优化 有JavaScript和css 图片等
现在要处理的是对html 进行压缩
Google上有个项目 HtmlCompressor 还是不错的 可以直接看他的单元测试
jar 可以到源代码中找到 需要注意yuicompressor版本

现在只上个测试例子，做个记录

import java.io.BufferedReader;
import java.io.BufferedWriter;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileWriter;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.Reader;
import java.io.Writer;

import org.junit.After;
import org.junit.Before;
import org.junit.Test;

import com.googlecode.htmlcompressor.compressor.HtmlCompressor;

public class HtmlCompressorTest {
	
	private static final String resPath = "d:/";

	@Before
	public void setUp() {
	}

	@After
	public void tearDown() {
	}
	
	@Test
	public void testEnabled() throws Exception {
		String source = readResource("testEnabled.htm");
		
		HtmlCompressor compressor = new HtmlCompressor();
		compressor.setRemoveComments(true);
		compressor.setRemoveIntertagSpaces(true);
		compressor.setRemoveQuotes(true);
		compressor.setRemoveMultiSpaces(true);
		compressor.setCompressJavaScript(true);
		compressor.setCompressCss(true);
		writeResource("testEnabledResult.html",compressor.compress(source));
	}
	
	private String readResource(String filename) {
		StringBuilder builder = new StringBuilder();
		try {
			FileInputStream stream = new FileInputStream(new File(resPath + filename));
			try {
				Reader reader = new BufferedReader(new InputStreamReader(stream));
				char[] buffer = new char[8192];
				int read;
				while ((read = reader.read(buffer, 0, buffer.length)) > 0) {
					builder.append(buffer, 0, read);
				}
			} finally {
				stream.close();
			}
		} catch (IOException e) {
			e.printStackTrace();
		}
		return builder.toString();
	}
	
	private void writeResource(String filename, String content) {
		try {
			Writer output = new BufferedWriter(new FileWriter(new File(resPath + filename)));
			try {
				output.write(content);
			} finally {
				output.close();
			}
		} catch (IOException e) {
			e.printStackTrace();
		}
	}
