Java对象转出json并过滤指定属性

List<User> list = userMapper.fenYe(pageIndex * limit, limit, user);
JsonConfig jsonConfig = new JsonConfig();
PropertyFilter filter = new PropertyFilter() {
public boolean apply(Object source, String name, Object value) {
if ("password".equals(name) || "createDate".equals(name)) {
return true;
}
return false;
}
};
jsonConfig.setJsonPropertyFilter(filter);
String json = JSONArray.fromObject(list, jsonConfig).toString();
