Serializable class without 'readObject()' and 'writeObject()'

Reports Serializable classes that do not implement readObject() and writeObject() methods.

If readObject() and writeObject() methods are not implemented, the default serialization algorithms are used, which may be sub-optimal for performance and compatibility in many environments.

Locating this inspection


Can be used to locate inspection in e.g. Qodana configuration files, where you can quickly enable or disable it, or adjust its settings.

Via Settings dialog

Path to the inspection settings via IntelliJ Platform IDE Settings dialog, when you need to adjust inspection settings directly from your IDE.

Settings or Preferences | Editor | Inspections | Java | Serialization issues

Use the following options to configure the inspection:

  • List classes whose inheritors should not be reported by this inspection. This is meant for classes that inherit Serializable from a superclass but are not intended for serialization.

  • Whether to ignore Serializable classes without non-static fields.

  • Whether to ignore Serializable anonymous classes.
