我发现可以为我的 Eclipse 3.7 RCP 应用程序创建首选项页面。
如何做到这一点在此处描述。

问题：
是否可以在preferecne-page 中添加一个条目字段，该字段将被加密保存在安全存储中？

到目前为止，我只找到了一种以编程方式使用安全存储的方法。
这对我来说不是一个解决方案，因为首选项页面条目会自动保存。

解决方案： 我做到了，正如 Tonny Madsen 所说：

  • 扩展SecureIPreferenceStore类，这是一个IPreferenceStore.
  • 通过使用类型的私有变量，使新类将所有首选项存储在安全存储中ISecurePreferences
  • 将新类设置为首选项页面的 PreferenceStore

ScopedPreferenceStore 的扩展


public class SecureIPreferenceStore extends ScopedPreferenceStore {



/* Current class will override all storage and loading methods, using this secure preferenceStore, to store all preferences in an encrypted way. */ 
    private static final ISecurePreferences SECURE_PREFERENCES = SecurePreferencesFactory.getDefault();



/**
* Use this class to retrieve an instance of  {@code SecureIPreferenceStore}, which will store all preferences in the default secure storage.
 * 
 * @param context - the scope to store to, e.g. {@link org.eclipse.core.runtime.preferences.ConfigurationScope ConfigurationScope} 
 * or {@link org.eclipse.core.runtime.preferences.InstanceScope InstanceScope}
 * 
* @param qualifier - the qualifier to look up the preference node. An example of a qualifier would be the plug-in identifier that the preference is associated with,
* (e.g. the "org.eclipse.core.resources" uses the preference node in the instance scope where the preferences for "org.eclipse.core.resources" are stored)
*/
public SecureIPreferenceStore(IScopeContext context, String qualifier){
        super(context, qualifier);
}



@Override
public void setValue(String name, boolean value) {
    try {
        SECURE_PREFERENCES.putBoolean(name, value, true);
    } catch (StorageException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
}



@Override
public void setValue(String name, double value) {
    try {
        SECURE_PREFERENCES.putDouble(name, value, true);
    } catch (StorageException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
}



@Override
public void setValue(String name, float value) {
    try {
        SECURE_PREFERENCES.putFloat(name, value, true);
    } catch (StorageException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
}



@Override
public void setValue(String name, int value) {
    try {
        SECURE_PREFERENCES.putInt(name, value, true);
    } catch (StorageException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
}



@Override
public void setValue(String name, long value) {
    try {
        SECURE_PREFERENCES.putLong(name, value, true);
    } catch (StorageException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
}



@Override
public void setValue(String name, String value) {
    try {
        SECURE_PREFERENCES.put(name, value, true);
    } catch (StorageException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
}



@Override
public boolean getBoolean(String name) {
    Boolean result = false;
    try {
        result = SECURE_PREFERENCES.getBoolean(name, result);
    } catch (StorageException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
    return result;
}



@Override
public double getDouble(String name) {
    Double result = 0.0;
    try {
        result = SECURE_PREFERENCES.getDouble(name, result);
    } catch (StorageException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
    return result;
}



@Override
public float getFloat(String name) {
    Float result = 0.0f;
    try {
        result = SECURE_PREFERENCES.getFloat(name, result);
    } catch (StorageException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
    return result;
}



@Override
public int getInt(String name) {
    int result = 0;
    try {
        result = SECURE_PREFERENCES.getInt(name, result);
    } catch (StorageException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
    return result;
}



@Override
public long getLong(String name) {
    Long result = 0L;
    try {
        result = SECURE_PREFERENCES.getLong(name, result);
    } catch (StorageException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
    return result;
}
}

FieldEditorPreferencePage 中新类的用法：


    @Override
    public void init(IWorkbench workbench) {
        setPreferenceStore(
                new SecureIPreferenceStore(ConfigurationScope.INSTANCE, 
                        "de.vogella.rcp.preferences.secure") );
        setDescription("A demonstration of a preference page implementation");
    }

这个我没试过，但是...

我会添加自己IPreferenceStore的安全存储，然后FieldEditors在首选项页面中使用常用的。

ScopedPreferenceStore最简单的方法是重写子类getStorePreferences()以返回一个新的IEclipsePreferences. EclipsePreferences这可能是覆盖各种internal...(...)接口方法的子类ISecurePreferences。鉴于内部方法与 的方法非常匹配ISecurePreferences，这可能不会非常困难:-)
