去除富文本格式

1、写一个公共类

package com.boyutec.oss.sys.util;

import java.io.ByteArrayInputStream;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.io.Reader;

import javax.swing.text.html.HTMLEditorKit;
import javax.swing.text.html.parser.ParserDelegator;

public class Html2Text extends HTMLEditorKit.ParserCallback {

private static Html2Text html2Text = new Html2Text();

StringBuffer s;

public Html2Text() {
}

public void parse(String str) throws IOException {

InputStream iin = new ByteArrayInputStream(str.getBytes());
Reader in = new InputStreamReader(iin);
s = new StringBuffer();
ParserDelegator delegator = new ParserDelegator();
// the third parameter is TRUE to ignore charset directive
delegator.parse(in, this, Boolean.TRUE);
iin.close();
in.close();
}

public void handleText(char[] text, int pos) {
s.append(text);
}

public String getText() {
return s.toString();
}

public static String getContent(String str) {
try {
html2Text.parse(str);
} catch (IOException e) {
e.printStackTrace();
}
return html2Text.getText();
}

}

2、可以直接调用：Html2Text.getContent("需要处理的字符串);
