我正在使用Android Hive 教程.它之前工作正常,但现在它不起作用.
当我注册我的设备时,它会被注册,我可以在我的网页上看到已注册的设备,但是当我发送消息时,我无法在设备上接收它.以下是我注册时收到的一些消息GCM:
03-05 12:18:09.200: E/GCMRegistrar(1008): internal error: retry receiver class not set yet
03-05 12:18:09.500: E/URL(1008): > http://10.0.2.2/gcm_server_php/register.php

03-05 12:23:03.830: E/UnRegister Receiver Error(1008): > Receiver not registered: com.google.android.gcm.GCMBroadcastReceiver@40ff0d88
正如你上面提到的,我已经更新了pom
<distributionManagement>
<repository>
<id>deployment</id>
<name>deployment</name>
<url>http://localhost:8080/nexus-webapp-1.9.2/content/repositories/releases</url>
</repository>
<snapshotRepository>
<id>snapshots</id>
<name>Internal Snapshots</name>
<url>http://localhost:8080/nexus-webapp-1.9.2/content/repositories/snapshots</url>
</snapshotRepository>
</distributionManagement>
并且还改变了settings.xml这样的东西
<server>
<id>deployment</id>
<username>deployment</username>
<password>deployment123</password>
</server>
<server>
<id>snapshots</id>
<username>deployment</username>
<password>deployment123</password>
</server>
但是当我使用mvn deploymaven命令进行部署时,我得到了这样的异常:
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-deploy-plugin:2.5:deploy (default-deploy) on project Test: Failed to deploy artifacts: Could not transfer ar
tifact Test:Test:jar:0.0.1 from deployment (http://localhost:8080/nexus-webapp-1.9.2/content/repositories/releases): Failed to transfer file: http://localhost:8080/nexus-

ailed to …我使用以下代码设置cookie然后重定向.
String level=(String) request.getAttribute("level");
if(level!=null)
{
Cookie cookie=new Cookie("level",level);
cookie.setMaxAge(-1);
cookie.setPath("http://localhost:8080/saml");
response.addCookie(cookie);
response.sendRedirect("http://?localhost:8080/saml/someservices.jsp");
}
这段代码工作正常.但我想知道怎么做？因为当jsp引擎解析jsp代码时,它将首先遇到addCookie并发送重定向.它是否尽快添加cookie response.addCookie(cookie);？如果我以相反的方式给它,即首先sendRedirect()然后addCookie()呢？jsp引擎如何看待这个？
我为任务使用了自定义光标属性,但它不适用于ie浏览器.我使用了以下代码段.
<html>
<head>
<title>Custom Cursor</title>
<style>
h1{
cursor: url(http://www.franco.it/Images/Lookf.png), auto;
}
</style>
</head>
<body>
<h1>Custom Cursor</h1>
</body>
</html>
它适用于Chrome,Firefox和Safari - 除了IE之外的所有内容.有些文章说我应该使用.cur格式,但如何将图像转换为cur？我找不到合适的链接来转换它.
谢谢.
我的数据库中有一个字符串和类型 varchar
{"available":"","bind":"0","hours":{"00:00":{"available":"","bind":"0","info":"","notes":"","price":"","promo":"","status":"none"}},"hours_definitions":[{"value":"00:00"}],"info":"","notes":"","price":"100","promo":"","status":"available"}
如何从中提取价格？
我是 Go lang 的初学者，我正在尝试使用 AWS 在 Go lang 和 Dynamodb 之间建立连接，并使用 Go lang 编写的 API 在 dynamodb 中插入数据。任何帮助，将不胜感激。
下面是我正在尝试做的代码：
package main
import "fmt"
import (
"github.com/aws/aws-sdk-go/aws"
"github.com/aws/aws-sdk-go/aws/session"
"github.com/aws/aws-sdk-go/aws/credentials"
"github.com/aws/aws-sdk-go/service/dynamodb"
"github.com/user/dynamo_connect/data"
)
func database_init() {
var testCredentials = credentials.NewStaticCredentials("Access_key", "secret_key", "")
sess, err := session.NewSession()
svc := dynamodb.New(sess, &aws.Config{
Region: aws.String("us-east-1"),
Credentials: testCredentials,
})
resp, err := data.UploadForumData(svc)
if err != nil {
fmt.Println("An error occurred while writing to the Employee table")
fmt.Println(err.Error())
}
fmt.Println(resp)
}
func main() {
database_init()
} …我想只使用CSS淡入和淡出效果.如果我移动或悬停在一个div元素上,那么我需要调用另一个DIV来淡入,然后它会在鼠标离开时淡出agsin.DOM元素调用和效果应该在CSS或CSS3.我不能使用javascript和Jquery.
<style>
#b
{
width: 200px;
height: 40px;
background: red;
border-radius: 10px;
text-align: center;
margin: 35px;
padding: 30px 0px;
box-shadow: 2px 4px 10px 2px;
opacity:0;
color: white;
font: 20px bold;
}
#a
{

border-radius: 10px;
text-align: center;

}
#a:hover + #b {

-webkit-animation:first 1s;

{ …如果您有一个变量X和Y并且您将此代码应用于它们:
int x = 10;
int y = 0;
x++;
y = x;
out(y);
然后代码的顺序对输出至关重要.
我的问题:是否有一个关键字让计算机按特定顺序运行代码,具体取决于变量？
selOrder是我为了这个例子而编写的关键字.它获得一个布尔值,并确定首先执行哪一行.
example:
{
int x = 10;
int y = 0;
bool order = true;
selOrder(order)
{
x++;
}
{
y = x;
}
out(y);
}
出:11
这个例子非常荒谬,它让这个问题看起来很可悲,但我完全认真,尽管在这个例子中这个关键词是没用的.我偶然发现了许多代码方案,它可能非常漂亮.
