反转义-StringEscapeUtils.unescapeHt

在读取数据库，展示用户图片时，出现如下代码：

<p>![](/upload/loan/1495264907356.jpg)&nbsp;</p><p>![](/upload/loan/1495264918245.jpg)&nbsp;</p><p>![](/upload/loan/1495168081723.jpg)&nbsp;</p><p>![](/upload/loan/1495168059259.jpg)&nbsp;</p>null

改存储夹杂空号字符。
而我需要的结果是：

<p>![](/upload/loan/1495264907356.jpg) </p><p>![](/upload/loan/1495264918245.jpg) </p><p>![](/upload/loan/1495168081723.jpg) </p><p>![](/upload/loan/1495168059259.jpg) </p>null

所以需要StringEscapeUtils类进行转义与反转义
demo如下：

import org.apache.commons.lang3.StringEscapeUtils;

public class TestAsyc {

    public static void main(String[] args) {

        String s = "&nbsp;<p>![](/upload/loan/1495264918245.jpg)&nbsp;</p>";

        String content = StringEscapeUtils.unescapeHtml4(s);// 反转义
        System.out.println(content);
    }
}

console:

 <p>![](/upload/loan/1495264918245.jpg) </p>
