Java对象中敏感字段泛型过滤
public static <T> T removeFiled(T obj)throws Exception{//需要过滤的敏感字段Set<String> set = new HashSet<>();set.add("password");//获取类中所有字段名Field[] fields = obj.getClass().getDeclaredFields();for (Field field : fields) {if (set.contains(field.getName())) {//开启字段权限field.setAccessible(true);//设置敏感字段为空field.set(obj,null);}}return obj;}
使用
@Test
public void test2() throws Exception {User user = userMapper.findById(1L);User newUser = removeFiled(user);System.out.println(newUser);}
