是用struts 的json插件进行序列化
代码如下：
Java代码
- @Test
- public 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("\\\\", "\\\\\\\\")
Java代码
- @Test
- public 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);
- }
