处理json中影响解析的多余引号

在xml中，敏感字符是尖括号，在json中，敏感字符是引号，上文中我们介绍了如何处理xml中的敏感字符，本文说说如何处理json中的敏感字符。
思路与上文相同，不再赘述。直接上代码：
json–>javaBean

 @Test public void test1() { String json = "{\"id\":\"1\",\"name\":\"红\"楼\"'梦\",\"price\":\"90\",\"author\":\"曹雪芹\"}"; List<String> tags = new ArrayList<String>(); Pattern pattern = Pattern.compile("\\\"([a-zA-Z0-9]*)\\\":"); Matcher m = pattern.matcher(json); while (m.find()) { tags.add(m.group(1)); } for (int i = 0; i < tags.size(); i++) { json = json .replaceAll("\\\"" + tags.get(i) + "\\\"", "^^" + tags.get(i) + "^^") .replaceAll(":\\\"", ":^^").replaceAll("\\\",", "^^,"); } json = json.replaceAll("\\\"}", "^^}").replaceAll("\\\"]", "^^]") .replaceAll("\"", "~~"); json = json.replace("^^", "\""); ObjectMapper mapper = new ObjectMapper(); try { Book book = mapper.readValue(json, Book.class); book.setName(book.getName().replace("~~", "\"")); System.out.println("作者：" + book.getAuthor() + "\n书名：" + book.getName()); } catch (IOException e) { e.printStackTrace(); } }

json–>List

 @Test public void test2() { String json = "[{\"id\":\"1\",\"name\":\"红\"楼\"'梦\",\"price\":\"90\",\"author\":\"曹雪芹\"},{\"id\":\"2\",\"name\":\"西游\"\"记\",\"price\":\"45\",\"author\":\"wuche\"ngen\"}]"; List<String> tags = new ArrayList<String>(); Pattern pattern = Pattern.compile("\\\"([a-zA-Z0-9]*)\\\":"); Matcher m = pattern.matcher(json); while (m.find()) { tags.add(m.group(1)); } for (int i = 0; i < tags.size(); i++) { json = json .replaceAll("\\\"" + tags.get(i) + "\\\"", "^^" + tags.get(i) + "^^") .replaceAll(":\\\"", ":^^").replaceAll("\\\",", "^^,"); } json = json.replaceAll("\\\"}", "^^}").replaceAll("\"", "~~"); json = json.replace("^^", "\""); ObjectMapper mapper = new ObjectMapper(); try { List<Book> books = mapper.readValue(json, new TypeReference<ArrayList<Book>>() { }); for (Book book : books) { book.setName(book.getName().replace("~~", "\"")); book.setAuthor(book.getAuthor().replace("~~", "\"")); System.out.println("作者：" + book.getAuthor() + "\n书名：" + book.getName()); } } catch (IOException e) { e.printStackTrace(); } }

这两段关于json的处理基本是一致的。
