禁用大型项目​​中的组件 [英] Disable components in a large project

问题描述

有很多开发人员和大三学生，我想禁用某些组件，例如<p:spacer>，以禁止将组件用于html/css问题.我想将诸如omnifaces/primefaces/richfaces之类的库的可用组件基本上限制为白名单/黑名单.

with a lot of developers and plenty of juniors I want to disable certain components such as <p:spacer> to prohibit using components for html/css issues. I want to limit the available components for libraries like omnifaces / primefaces / richfaces to a whitelist / blacklist thing basically.

这对于像omnifaces这样的库来说是合理的功能要求吗?还是很难构建/本地化?

Would this be a reasonable feature request for a library like omnifaces or is it to hard to build / to localized?

推荐答案

基本上，您可以通过提供自定义

Basically, you can achieve this by providing a custom Application implementation (based on ApplicationWrapper) wherein you override the desired createComponent() method and throw e.g. IllegalArgumentException when a blacklisted component type and/or renderer type is passed.

这是一个开球示例:

public class YourApplication extends ApplicationWrapper {

    private static final Set<String> BLACKLISTED_COMPONENT_TYPES = unmodifiableSet(new HashSet<>(asList(
        "org.primefaces.component.Spacer",
        "com.example.SomeComponentType",
        "com.example.OtherComponentType"
        // Etc..
    )));

    private final Application wrapped;

    public YourApplication(Application wrapped) {
        this.wrapped = wrapped;
    }

    @Override
    public UIComponent createComponent(FacesContext context, String componentType, String rendererType) {
        if (BLACKLISTED_COMPONENT_TYPES.contains(componentType)) {
            throw new IllegalArgumentException("You are not allowed to use this component.");
        }

        return super.createComponent(context, componentType, rendererType);
    }

    @Override
    public Application getWrapped() {
        return wrapped;
    }

}

您可以使其在此工厂中运行:

You can get it to run with this factory:

public class YourApplicationFactory extends ApplicationFactory {

    private final ApplicationFactory wrapped;

    public YourApplicationFactory(ApplicationFactory wrapped) {
        this.wrapped = wrapped;
    }

    @Override
    public Application getApplication() {
        return new YourApplication(wrapped.getApplication());
    }

    @Override
    public void setApplication(Application application) {
        wrapped.setApplication(application);
    }

}

在faces-config.xml中注册的地址如下:

<factory>
    <application-factory>com.example.YourApplicationFactory</application-factory>
</factory>
