今天在写公司后台管理系统，调用程序接口发现，返回值是php

&lt;p&gt;&lt;img src=&quot;https://wis3dom.baidu.com/Public/static/um/php/../../../upfile/20170214/14870444271696.png&quot; _src=&quot;https://wis3dom.baidu.com/Public/static/um/php/../../../upfile/20170214/14870444271696.png&quot;/&gt;&lt;/p&gt;&lt;p&gt;&lt;img src=&quot;https://wis3dom.baidu.com/Public/static/um/php/../../../upfile/20170214/14870444425034.png&quot; _src=&quot;https://wis3dom.baidu.com/Public/static/um/php/../../../upfile/20170214/14870444425034.png&quot;/&gt;&lt;/p&gt;&lt;p&gt;&lt;img src=&quot;wis3dom.baidu.com/Public/static/um/php/../../../upfile/20170214/14870444571207.png&quot; _src=&quot;https://wis3dom.baidu.com/Public/static/um/php/../../../upfile/20170214/14870444571207.png&quot;/&gt;&lt;/p&gt;&lt;p&gt;&lt;br/&gt;&lt;/p&gt;

结果界面不显示，还不理解这是啥，原来是转义，借助php函数htmlspecialchars_decode() 经粗略改写 java实现html

static Map<String,String> html_specialchars_table = new Hashtable<String,String>();
    static {
        html_specialchars_table.put("&lt;","<");
        html_specialchars_table.put("&gt;",">");
        html_specialchars_table.put("&amp;","&");
        html_specialchars_table.put("&quot;","\"");
    }
    static String htmlspecialchars_decode(String s){

        for (Map.Entry entry : html_specialchars_table.entrySet()) {

            Object key = entry.getKey( );
            String val = html_specialchars_table.get(key);
            s = s.replaceAll(key.toString(), val);
        }

        return s;
    }

因为使用的thymeleaf 引擎，因此必须使用标签 th:utext ,java
