1、添加maven引用

<dependency>
<groupId>org.apache.commons</groupId>
<artifactId>commons-text</artifactId>
<version>1.1</version>
</dependency>

2、代码如下

1. import org.apache.commons.lang.StringEscapeUtils;
2.  
    
3.  
   public class MainClass {
4.  
   public static void main(String[] args) {
5.  
   String strHTMLInput = "<P>MyName<P>";
6.  
   String strEscapeHTML = StringEscapeUtils.escapeHtml(strHTMLInput);
7.  
   String strUnEscapeHTML = StringEscapeUtils.unescapeHtml(strEscapeHTML);
8.  
   System.out.println("Escaped HTML >>> " + strEscapeHTML);
9.  
   System.out.println("UnEscaped HTML >>> " + strUnEscapeHTML);
10.  
    }
11.  
    }

     

    搜索引擎里还看到用jsoup的，没具体去实现，先记录

java 转义与反转义
