Java Google Guice嵌套辅助注入

我有一个工厂，看起来像这样：

public class Factory {

    public Client createClient(String url) {
        UrlBuilder urlBuilder = new UrlBuilder(url);

        DefaultHttpClient httpClient = new DefaultHttpClient();
        HttpProcessor processor = new CompressionHttpProcessor();
        httpClient.addRequestInterceptor(processor);
        httpClient.addResponseInterceptor(processor);

        return new Client(httpClient, urlBuilder);
    }
}

public class Facade {

    private Factory factory;
    private String url;

    public Facade(Factory factory) {
        this.factory = factory;
    }

    public void doStuff() {
        Client client = factory.createClient(url);
        // do stuff with client
    }

    public void setUrl(String url) {
        this.url = url;
    }
}

像这样的课程：

public class Factory {

    public Client createClient(String url) {
        UrlBuilder urlBuilder = new UrlBuilder(url);

        DefaultHttpClient httpClient = new DefaultHttpClient();
        HttpProcessor processor = new CompressionHttpProcessor();
        httpClient.addRequestInterceptor(processor);
        httpClient.addResponseInterceptor(processor);

        return new Client(httpClient, urlBuilder);
    }
}

public class Facade {

    private Factory factory;
    private String url;

    public Facade(Factory factory) {
        this.factory = factory;
    }

    public void doStuff() {
        Client client = factory.createClient(url);
        // do stuff with client
    }

    public void setUrl(String url) {
        this.url = url;
    }
}

我如何正确地使用GoogleGuice来做同样的事情？我尝试了辅助注射，但我不确定如何创建“UrlBuilder”。有人能帮忙吗

Guice减轻了对工厂的需求，并在您的应用程序中使用了新技术 Java代码

您的

工厂

代码似乎违反了该原则

您可能需要重新设计facade，以便它通过注入（使用setClient）方法接收

客户机
对象。
我创建了一个保存URL的设置类，并执行了以下操作：

public MyModule extends AbstractModule {
    private final Settings settings;
    public MyModule(Settings settings) {
        this.settings = settings;
    }

    // configure

    @Provides
    private UrlBuilder createUrlBuilder(Settings settings) {
        return new UrlBuilder(settings.getUrl());
    }
}

它有点用，但我不确定我是否喜欢它
