Where's the file LogoutController.grooxy in project after installed Grails Spring Security 2.0RC plugin

Sometimes, we need override class LoginController or LogoutController when using ajax authentication function of Grails Spring Security plugin. But in 2.0RC version, after you run s2-quickstart, the LoginController and LogoutController class are not created in the grails-app\controllers folder as before. where're they now? Oh, they're hidden deeply:

---

\target\work\plugins\spring-security-core-2.0-RC2\grails-app\controllers\grails\plugin\springsecurity

---

if you still can not find it, please use file search function in the IDE.

Remember copying the file to grails-app\controllers folder before you using and override it.

get error when use logout in the page genarated by Grails Spring Security Pluin

the error message is:

---

    The specified HTTP method is not allowed for the requested resource.

---

reason:
Grails Spring Security Plugin use GET request to logout, but its config set default logout request methord to POST for safety reason.

solution:
in Config.groovy, add:

grails.plugin.springsecurity.logout.postOnly = false

or, just use POST request to logout in your application, that's more safe.

Android程序通过http访问自己PC上的web应用程序，总是返回请求被拒绝

       最近使用Android studio学习Android手机程序开发，并且采用第三方Android-Query库简化界面控件访问和http网络操作。我准备让我的Android程序访问我用Grails编写的很简单的web应用程序，并得到JSON数据。

      访问Grails Web应用的URL为：http://localhost:8090/GrailsTest1/main/index, 在浏览器中访问这个URL可以得到正确的JSON结果， 但我启动Android Genymotion模拟器， 代码中用Android-Query的ajax方法访问始终返回“Network Error”，为更清楚地得到网络错误的具体原因，把AQuery的ajax访问改成Android的HttpClient异步网络调用，得到返回的错误为请求被对方拒绝。

      在网上发帖咨询，有人说可能是CORS的原因，但我发现我的Android代码可以访问ip.jsontest.com并得到正确的JSON结果，如果是CORS的问题，在对客户端程序进行相应CORS的修改前，访问任何web应用都不应该得到结果的，因此排除是CORS问题。

      继续在网上搜索并试验，最终发现了原因：Android模拟器会使用localhost表示自己的地址，而提供另一个特定的IP作为宿主主机地址给Android程序使用，经过测试，这个IP地址是10.0.3.2。我把Android程序中访问web应用的地址改成http://10.0.3.2:8090/GrailsTest1/main/index。奇迹出现了，看到了企盼已久的JSON返回结果。

use Android-Query in Android Studio

1. in build.gradle, add:

dependencies {
  compile 'com.googlecode.android-query:android-query:0.24.3'
}

2. in Fragment class：

public static class PlaceholderFragment extends Fragment {
  private AQuery aq;
  public PlaceholderFragment() {
  }

  @Override
  public View onCreateView(LayoutInflater inflater,
                           ViewGroup container,
                           Bundle savedInstanceState) {
    View rootView = inflater.inflate(R.layout.fragment_main,
                                     container, 
                                     false);
    aq = new AQuery(getActivity(), rootView);
    aq.id(R.id.button1).clicked(this, "onButtonClick");
    return rootView;
  }

  public void onButtonClick(View view) {
    aq.id(R.id.editText).text("test text");
  }
}
