Java正确转换html编码

Java 中能將 html 編碼正確轉換的套件: org.apache.commons.lang.StringEscapeUtils。

String source = "The less than sign (<) and ampersand (&) must be escaped before using them in HTML";
String escaped = escapeHtml(source);  //转义
System.out.println(escaped);

source = "{&quot;zbjson&quot;:{&quot;shouJianHao&quot;:&quot;660eb728-a94c-7c6b-c47d-f617ec85528a&quot;},&quot;cb1json&quot;:[{&quot;gongYouRen&quot;:&quot;&quot;,&quot;gongYouLx&quot;:&quot;1&quot;,&quot;gongYouQl&quot;:&quot;1&quot;,&quot;gongYouFe&quot;:&quot;&quot;,&quot;qiTaSm&quot;:&quot;&quot;,&quot;shouJianHao&quot;:&quot;660eb728-a94c-7c6b-c47d-f617ec85528a&quot;,&quot;poid&quot;:&quot;&quot;}],&quot;cb2json&quot;:[{&quot;bianHao&quot;:&quot;1&quot;,&quot;caiLiaoMc&quot;:&quot;&quot;,&quot;leiBie&quot;:&quot;1&quot;,&quot;fenShu&quot;:&quot;&quot;,&quot;shouJianHao&quot;:&quot;660eb728-a94c-7c6b-c47d-f617ec85528a&quot;}]}";
escaped =org.apache.commons.lang.StringEscapeUtils.unescapeHtml(source); //反转义
System.out.println(escaped);
