StringEscapeUtils类转义与反转义（对js sql html xml等代码进行转义）

public class Test {

         String s = "
111111
";  
         System.out.println(StringEscapeUtils.escapeHtml3(s));  
           
         String u = "<p><em><strong><span style="background-color:#ff0000;">111111</span></strong></em></p>";  
         System.out.println(StringEscapeUtils.unescapeHtml3(u)); 
}
