根据Spring Security 4.0.0文档:

4.2.4注销处理

logout元素通过导航到特定URL添加了对注销的支持.默认的注销URL是/ logout,但您可以使用logout-url属性将其设置为其他内容.有关其他可用属性的更多信息,请参见命名空间附录.

但是,在doc中遵循安全设置后,URL/logout不会显示注销页面.相反,它表明

相反,URL /登录正常.

以下是我的设置:

我可以将Bitmap转换为String吗？然后将String转换回Bitmap？

提前致谢.

我想将android模拟器上的数据发送到本地主机网站,并获得一些结果.

String temp = "http://10.0.2.2:8888/json/rec?user_data=" + user_data + "&friends=" + friends;
URL url = new URL(temp);

HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();
urlConnection.setReadTimeout(5000);
InputStreamReader is = new InputStreamReader(urlConnection.getInputStream(), "UTF-8");
String output = "";
while(is.ready()) {
    output += is.read();
}

这是例外.

java.io.IOException: Malformed ipv6 address: [10.0.2.2:8888]

为什么这么说？有人能帮助我吗？提前致谢.
