小编Pet*_*der的帖子

我已将多模块项目上传到中央bundle.jar,因此出现此问题: 所以Nexus找不到了pom.asc.

但是如果文件可用,文件怎么会丢失

假设我有这样的选择:

<select size="4">
  <option id="1">Please wait ...</option>
  <option id="2">Please wait ...</option>
  <option id="3">Please wait ...</option>
  <option id="4">Please wait ...</option>
  <option id="5">Please wait ...</option>
</select>

我应该看到一个包含右侧滚动条的4个元素的列表.

我现在要做的是如果选项以某种方式变得可见(滚动和/或初始化),则通过ajax加载文本.

编辑:

最后,由于巨大的元数据传输,我不会加载它们.这是我必须上传的请求(发送到服务器):

这对于单个元素的延迟加载是不可接受的.

我喜欢改进连续交付.我正在使用Tomcat 8和maven.

我mvn tomcat:redeploy用来部署webapp.

在tomcat文档中我找到了这个部分:

远程部署新的应用程序存档(WAR)

如果安装和启动成功,您将收到(...)

否则,响应将以FAIL开头并包含错误消息.

可能的原因FAIL之一是休息:

尝试启动新的Web应用程序时遇到异常.

所以我想在启动时抛出一个异常,所以在web.xml我写道:

<负载上启动> 1 </负载上启动>

到org.springframework.web.servlet.DispatcherServlet-Servlet.然后我写了一个单身人士:

@Service
public class AvoidStartupOnMissingDatabase implements SmartInitializingSingleton {

    @Override
    public void afterSingletonsInstantiated() {
        throw new RuntimeException("Do not deploy this app!");
    }
}

这会导致这个Stacktrace:

使用jstack我得到了一个运行的线程树.

1. 以下是Thread.State的含义:

   • 等候
   • TIMED_WAITING
   • RUNNABLE

2. 什么意思是tid和nid？

3. 线程的标题就像

   "事件批处理(Spring UAA/1.0.2)"守护程序prio = 10 tid = 0x0000000041e27800 nid = 0x363b等待条件[0x00007f9a89267000]

   • 如何导航到"等待条件"-address的源代码行

我有一个类和一个子类

01 public class A{
02   void test(){};
03   public class B{
04     void test(){
05       test();
06     }
07   }
08 }

好吧,在05行id喜欢访问类A的方法测试.但我进入循环因为我不知道如何指定使用类A的方法.

有任何想法吗？

像这样读JSON-Service:

$.ajax({
  url:'activeIDs',
  success : function(data){ // data = [14,15]
    var tableRows = [];
    for (var dataIndex=0; dataIndex < data.length; dataIndex++) {
      var isLast = dataIndex == (data.length - 1);
      $.ajax({
        url: 'info?id=' + data[dataIndex],
        success: function(data2) { // "foo", "bar"
          tableRows.push(data2.name);
          if (isLast) {
            alert(tableRows.length);
          }
        }
      });
    }
  }
});

第一个网络跟踪是:

1. activeIDs = [14,15]
2. info？id = 14(需要2秒)= "foo"
3. info？id = 15(需要4秒)= "bar"

在这种情况下,警报给出"2".

秒网络跟踪是不同的:

1. activeIDs = [14,15];
2. info？id = 14(需要20秒)= "foo"(现在需要很长时间)
3. info？id = 15(需要1秒)= "bar"

在这种情况下警报提供 …

有这个HTML

<select>
 <option>Foo</option>
</select>

<select>
 <option>Foo</option>
</select>

处理了secodn输入.如何避免这种影响？

我在命令行中运行"mvn install"并被下面的错误卡住了.

Caused by: org.apache.maven.project.DependencyResolutionException: Could not resolve dependencies for project com.detux.vios:common-entity:jar:2_0_0:

我检查m2\repository\org\hibernate\hibernate-entitymanager\3.6.2.FINAL \,这里是它的内容

我还尝试将新的远程存储库添加到pom.xml,但它仍然无效

我有一个要求,即不应将值缓存在服务器中,也不应将浏览器缓存为域和会话上的cookie.

所以我选择永久重定向到价值

Servlet的:

@Override
protected void service(HttpServletRequest request,
        HttpServletResponse response) throws ServletException, IOException {
    String key = request.getParameter("key");
    String val = request.getContentType();
    if (val != null && val.length() == 0) {
        val = null;
    }
    String repeatText = request.getParameter("repeatText");
    if (val != null && repeatText == null) {
        response.setStatus(301); // moved permanent
        response.addHeader("Location", "?repeatText=" + val);
        System.out.println("Write");

            response.addHeader("pragma", "no-cache");
            response.addIntHeader("expires", BROWSER_CACHE_DAYS);

有这个课

public abstract class Mother{
  public class Embryo{
    public void ecluse(){
      bear(this);
    }
  }
  abstract void bear(Embryo e);
}

只有我有一个母亲的实例,我才能创建一个胚胎实例:

new Mother(){...}.new Embryo().ecluse();
