基于状态机的字符流脱敏实现，零正则表达式，简单高效，可用于日志脱敏。
//注册脱敏字段
SensitiveInfoRegistry.put("name", SensitiveType.CHINESE_NAME);
SensitiveInfoRegistry.put("idCard", SensitiveType.ID_CARD);
SensitiveInfoRegistry.put("mobile", SensitiveType.MOBILE_PHONE);
SensitiveInfoRegistry.put("phone", SensitiveType.FIXED_PHONE);
SensitiveInfoRegistry.put("email", SensitiveType.EMAIL);
SensitiveInfoRegistry.put("address", SensitiveType.ADDRESS);
//参考测试用例
@Test
public void testJsonWithMultipleSensitiveFields() {
String input = "aaaaaaaaaaaaaaa{\"name\":\"李四\",\"idCard\":\"110101199003072345\",\"mobile\":\"13800138000\",\"email\":\"[email protected]\"}";
String expected = "aaaaaaaaaaaaaaa{\"name\":\"李*\",\"idCard\":\"110******345\",\"mobile\":\"138******8000\",\"email\":\"******.com\"}";
assertEquals(SensitiveReplacer.deSensitiveString(input), expected);
