Can't serialize instance of class, Caused by: IllegalArgumentException: wrong number of arguments
已回答
I'm writing a class which implemets PersistentStateCompontent, trying to make a custom List of RunnerAndConfigurationSettings persistent. This class is implemented like the following:
@State(name = "SettingsProvider", storages = @Storage("settingsProvider.xml"))
public class SettingsProvider implements PersistentStateComponent<SettingsProvider.State> {
public final State myState = new State();
public static final SettingsProvider getInstance() {
return ServiceManager.getService(SettingsProvider.class);
}
public static final class State {
public List<RunnerAndConfigurationSettings> configSettings;
public State() {
configSettings = new ArrayList<>();
}
@Override
public boolean equals(Object obj) {
if(!(obj instanceof SettingsProvider.State)) return false;
return ((State) obj).configSettings == this.configSettings;
}
}
@Nullable
@Override
public SettingsProvider.State getState() {
return myState;
}
@Override
public void loadState(@NotNull State state) {
XmlSerializerUtil.copyBean(state, myState);
}
public List<RunnerAndConfigurationSettings> getConfigSettings() {
return myState.configSettings;
}
public void setConfigSettings(List<RunnerAndConfigurationSettings> configSettings) {
myState.configSettings = configSettings;
}
}
And the relevant part of my plugin.xml:
<extensions defaultExtensionNs="com.intellij">
<applicationService serviceImplementation="com.luke.switchrunconfig.SettingsProvider"
serviceInterface="com.luke.switchrunconfig.SettingsProvider"/>
</extensions>
And I always get the follwing Error

Try changing this method to:
Class declaration can just be:
I still get the same Error message
My class now looks like this:
@State(name = "SettingsProvider", storages = @Storage("settingsProvider.xml"))
public class SettingsProvider implements PersistentStateComponent<SettingsProvider> {
public List<RunnerAndConfigurationSettings> configSettings;
public SettingsProvider() {
configSettings = new ArrayList<>();
}
public static final SettingsProvider getInstance() {
return ServiceManager.getService(SettingsProvider.class);
}
@Nullable
@Override
public SettingsProvider getState() {
return this;
}
@Override
public void loadState(@NotNull SettingsProvider state) {
XmlSerializerUtil.copyBean(state, this);
}
public List<RunnerAndConfigurationSettings> getConfigSettings() {
return configSettings;
}
public void setConfigSettings(List<RunnerAndConfigurationSettings> configSettings) {
this.configSettings = configSettings;
}
}
Here is my implementation that I use, all state that is persisted is stored in the fields of the PersistentStateComponent.
Well, this looks pretty similar to mine. During trial and error I found out that I don't get this error, when I only try to serialize for example Strings. So the reason might be that the Interface RunnerAndConfigurationSettings is not serializable.
I'll try and write my own implementation for serializing this
