小编dev*_*dev的帖子

这是我第一次使用yaml文件,所以我首先想到的是找到任何可以帮助我解析文件的库.

我找到了两个库YamlBean,SnakeYaml我不确定我要使用哪个库.

这是我尝试解析的文件的示例

users:
  user1:
    groups:
    - Premium
  user2:
    groups:
    - Mod
  user3:
    groups:
    - default
groups:
  Mod:
    permissions:
      test: true
    inheritance:
    - Premium
  default:
    permissions:
      test.test: true
    inheritance:
    - Mod
  Admin:
    permissions:
      test.test.test: true
    inheritance:
    - Mod

该文件将更改为动态,因此我不知道该文件将包含多少用户或组.

我想从中获取的信息是用户名和这样的组

user1 Premium
user2 Mod
user3 default

并且从组中只有组名,就像这样

Mod
default
Admin

任何人都可以让我从这里开始？什么是最好用的库？YamlBean或SnakeYaml.

我想,我需要将信息保存在我很容易迭代的内容中.

我的应用程序(java spring-core)有几个并发运行的线程并访问db,我在某个高峰时间遇到异常

我不时地在日志中看到以下堆栈跟踪,HttpClient套接字超时试图text/script从另一个服务器访问内容.我的问题是我应该在Linux上检查在Weblogic上运行的J2EE应用程序的配置设置是什么？我特意寻找以下内容.

• JVM超时参数
• HttpClient PARAMS
• Weblogic超时参数或任何其他配置,如线程数等.
• J2EE应用程序设置,如servlet配置等.
• 操作系统资源,如线程,文件处理程序和cpu
• 可能影响套接字连接的任何其他配置设置
• 线程转储会有帮助吗？

这是我的代码

HTTPResponse httpClientResponse;
//do some stuff
httpClientResponse.getStatusCode(); // this is where it fails

这就是堆栈跟踪

谢谢

我将使用下面的调查结果更新我的问题.

1. 没有明确的超时设置,HttpClient这意味着服务器的http会话超时可能正在生效.
2. SO_TIMEOUTfor HttpClient …

我对java不太熟悉,这让我发疯了.我写了一个java程序FileManagement,我需要从命令行运行它.

我可以从命令行编译它javac FileManagement/*.java,它将创建该文件夹中的所有类但是当我尝试java FileManagement.Main它时说:

线程"main"中的异常java.lang.NoClassDefFoundError:FileManagement/Main

问题是我在远程计算机上尝试了相同的程序,它运行正常.它不适用于我的.

我正在使用NodeJS,Scoket.io

我正在尝试发送Facebook等通知.如果有1000个用户,而用户A有50个朋友,则通知将发送给这50个用户.我不想为所有用户播放

有效的方法是什么？

我在SOAP UI中使用模拟服务作为我的服务器端来获取我从Java Web服务客户端发出的soap请求的响应.

我的Java Web服务客户端形成了一个正确的请求,但我收到以下响应:

  </soapenv:Body>
</soapenv:Envelope>

我已将这些参数设置为false,但问题仍然存在:

我在日志中看到了正确的请求,但是当我看到tcpdump请求为空时.标签为空:

假设我通过脚本编写 cron 文件并直接在 /var/spool/cron/crontabs/. 当crontab -e我退出编辑器时，使用命令crontab 检查语法。有什么办法可以通过脚本做同样的检查吗？

我从 logcat 收到以下消息：

08-16 11:34:36.257: W/BroadcastQueue(1040):
 Unable to launch app com.abc.xyz/10192 for broadcast Intent
 { act=android.intent.action.BOOT_COMPLETED flg=0x8000010 (has extras) }: process is not permitted to autostart

我的manifest.xml看起来像这样：

<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"/> 
<receiver android:name="com.abc.xyz.BootComplete" >
        <intent-filter>
            <action android:name="android.intent.action.BOOT_COMPLETED"/>
        </intent-filter>
</receiver>

我尝试了很多方法，但都不起作用。我知道还有其他问题。谢谢。

我在XSLT 2.0中尝试日期格式化.当我尝试在我的工作区中运行它时运行正常,我得到了适当的响应.但是当我在JBoss eap 6.1上部署我的jar后尝试实现相同的功能时,我得到以下错误:

尝试使用 JAXB 进行编组时出现异常。

这是堆栈跟踪：
