在xml中，敏感字符是尖括號，在json中，敏感字符是引號，上文中我們介紹了如何處理xml中的敏感字符，本文說說如何處理json中的敏感字符。
思路與上文相同，不再贅述。直接上代碼：
json–>javaBean

@Testpublic void test1() {String json = "{\"id\":\"1\",\"name\":\"紅\"樓\"'夢\",\"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書名："+ book.getName());} catch (IOException e) {e.printStackTrace();}}

json–>List

@Testpublic void test2() {String json = "[{\"id\":\"1\",\"name\":\"紅\"樓\"'夢\",\"price\":\"90\",\"author\":\"曹雪芹\"},{\"id\":\"2\",\"name\":\"西游\"\"記\",\"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書名："+ book.getName());}} catch (IOException e) {e.printStackTrace();}}

這兩段關于json的處理基本是一致的。
