struts json序列化遇上replaceAll就出问题
是用struts 的json插件进行序列化
?代码如下:
@Testpublic void test_json() throws JSONException {Map<String, String> map = new HashMap<String, String>();map.put("name", "whua"ng");String result = JSONUtil.serialize(map);System.out.println(result);String source = "{"result":"_jsonPlaceHolder"}";String result2=source.replaceAll(""" + "_jsonPlaceHolder" + """, result);System.out.println(result2);}
?运行结果如下:
{"name":"whua"ng"}
{"result":{"name":"whua"ng"}}
?
是用json解析时报错,{"result":{"name":"whua"ng"}} 不是合法的json字符串。
经过反复看,发现whua"ng中的斜杠没有了!!!!
问题出在replaceAll
?
解决方法如下
(添加).replaceAll("\\\", "\\\\\\\")
@Testpublic void test_json() throws JSONException {Map<String, String> map = new HashMap<String, String>();map.put("name", "whua"ng");String result = JSONUtil.serialize(map);System.out.println(result);String source = "{"result":"_jsonPlaceHolder"}";String result2 = source.replaceAll(""" + "_jsonPlaceHolder" + """,result.replaceAll("\\\", "\\\\\\\"));System.out.println(result2);}
