我想在Ubuntu vm中安装minikube(在虚拟框中).我为vm启用了VT-X/AMD-v.但是我得到了以下错误.

# minikube start
Starting local Kubernetes cluster...
E0217 15:00:35.395801    3869 start.go:107] Error starting host: Error creating host: Error with pre-create check: "This computer doesn't have VT-X/AMD-v enabled. Enabling it in the BIOS is mandatory".

 Retrying.

我今天首先安装了MongoDB 3.2.5.但是当我启动它并使用MongoDB shell时,它给了我以下警告:

C:\Windows\system32>mongo

我的操作系统是Microsoft Windows [版本10.0.10586].

我已经开始使用谷歌应用程序引擎和Spring 4开发一个Web应用程序.但现在我已经明白Spring 4并不完全支持Google应用程序引擎.现在我需要最新版本的Spring框架,完全支持谷歌应用程序引擎.有人可以帮帮我吗？

git pull、 git fetch和之间有什么区别git rebase？我感觉pull和fetch是一样的。

我试过这个doc在Ubuntu VM中安装和设置Kubernetes.我已经完成了3/4,现在kube-dns pod处于待定状态.我怎么能弄清楚这个？这里是结果kubectl get pods --namespace=kube-system和kubectl describe pod <pod name>

我尝试使用本指南创建自定义控制器服务。它在 nifi 1.9.2 版本中完美运行。但是当我尝试使用 NIFI 1.11.3 版本时，我遇到了以下问题。我用谷歌搜索了它，但找不到解决这个问题的方法。有人可以帮我吗？

我需要访问数据库并更新选择标记的选项。我的代码在这里。

 $(window).load(function () {

     $.getJSON('http://localhost/ABC/web/app_dev.php/doctorFillOption', function (data) {

         var length = data.length,
             element = null;
         $('#idcatFill').append('<select id ="idCat"  style="width:200px;margin-left:30px;margin-top:5px;" type="text"><option value=""></option>');

         for (var i = 0; i < length; i++) {
             row = data[i];
             alert("id" + row['id'] + ' ' + row['category_name']);
             $('#idcatFill').append(
                 '<option value="' + row['id'] + '">' + row['category_name'] + '</option>'
             );
         }

     });
     $('#idcatFill').append('</select><br/>');
 });

但是它没有选择权。需要帮忙。谢谢。

我有一个弹性搜索索引如下,

 {
  "payment_transaction": {
    "mappings": {
      "message_logs": {
        "properties": {
          "@timestamp": {
            "type": "date"
          },
          "changed_date": {
            "type": "date"
          },
          "created_date": {
            "type": "date"
          }
        }
      }
    }
  }
}

我需要添加另外三个字段(年,月,日).并且需要从现有字段(created_date)中分配值.created_date的格式为2016-11-22T22:20:21.000Z.我怎样才能做到这一点 ？弹性搜索版本是5.0.

我编写了一个spring boot应用程序来接受Http get Request并发送XML响应作为输出.我需要通过HTTP获取以下XML作为输出

<response xmlns="">
    <userId>235</userId>
    <amount>345.0</amount>
</response>

而我的DTO课程如下,

@XmlRootElement(name = "response")
public class CgPayment {
    @XmlElement
    private String userId;
    @XmlElement
    private double amount;

    @XmlElement
    public String getUserId() {
        return userId;
    }

    @XmlElement
    public void setUserId(String userId) {
        this.userId = userId;
    }

    @XmlElement
    public void setAmount(double amount) {
        this.amount = amount;
    }

    @XmlElement
    public double getAmount() {

        return amount;
    }
}

但是我得到了以下响应作为输出.

<CgPayment xmlns="">
    <userId>235</userId>
    <amount>345.0</amount>
</CgPayment>

如何更改根元素.响应类型为APPLICATION_XML_VALUE

我有一个方法如下:

public static void method() {

int i = 0;
i = i + 1;

}

我在静态方法中有一个int变量.并且该方法由几个线程访问.
我的问题是:

1. i变量是否符合竞争条件？
2. 如果在Spring Web应用程序中访问该方法并由多个用户同时访问该怎么办？

我使用 log4j 版本 2 作为 Tomcat 8 的记录器，现在问题是 catalina.out 文件不是每天轮换。我的 log4j.property 文件如下，

log4j.rootLogger = INFO, CATALINA, CONSOLE

# Define all the appenders
log4j.appender.CATALINA = org.apache.log4j.DailyRollingFileAppender
log4j.appender.CATALINA.File = ${catalina.base}/logs/catalina
log4j.appender.CATALINA.Append = true
log4j.appender.CATALINA.Encoding = UTF-8
# Roll-over the log once per day
log4j.appender.CATALINA.DatePattern = '.'yyyy-MM-dd'.log'
log4j.appender.CATALINA.layout = org.apache.log4j.PatternLayout
log4j.appender.CATALINA.layout.ConversionPattern = %d [%t] %-5p %c- %m%n

log4j.appender.LOCALHOST = org.apache.log4j.DailyRollingFileAppender
log4j.appender.LOCALHOST.File = ${catalina.base}/logs/localhost
log4j.appender.LOCALHOST.Append = true
log4j.appender.LOCALHOST.Encoding = UTF-8
log4j.appender.LOCALHOST.DatePattern = '.'yyyy-MM-dd'.log'
log4j.appender.LOCALHOST.layout = org.apache.log4j.PatternLayout

我有一个字符串

"age = 18 || name ='Mistic'|| civilstatus ='married'|| gender ='0'"

我需要替换"||" 通过"或".我试着跟随代码.

System.out.println("age = 18 || name = 'Mistic' || civilstatus = 'married' || gender = '0'".replaceAll("||", "OR"));

但我得到了

"ORaORgOReOR OR = OR OR1OR8OR OR |和| OR ORnORaORmOReOR OR = OR OR'ORMORiORsORtORiORcOR'OR OR |和| OR ORcORiORvORiORlORsORtORaORtORuORsOR OR = OR OR'ORmORaORrORrORiOReORdOR'OR OR |和| OR ORgOReORnORdOReORrOR OR = OR OR'OR0OR'OR"

我需要的是

"年龄= 18或姓名='Mistic'或civilstatus ='已婚'或性别='0'"

我怎样才能做到这一点.

编辑我已经阅读了这个问题的问题和答案,并不是类似的.因为这个问题是关于替换字符串而我的问题是关于为我的代码获取不熟悉的结果.
