我正在尝试使用@PreAuthorize注释的弹簧安全性(用户角色授权)的示例,遇到以下错误.

Caused by: org.springframework.beans.BeanInstantiationException:

我的WebSecurityConfigurerAdapter …

我有这样的课:

public class Test {
    private String Fname;
    private String Lname;
    private String Age;
    // getters, setters, constructor, toString, equals, hashCode, and so on
}

和一个List<Test> testList充满Test元素的列表.

如何获得age使用Java 8的最小值和最大值？

我在日志中的时间戳格式如下

2016-04-07 18:11:38.169  which is  yyyy-MM-dd HH:mm:ss.SSS

这个日志文件不是实时的（存储的/旧的），我试图用 logstash @timestamp 值替换这个时间戳，以改进 Kibana 可视化。

我在 logstash 中的过滤器如下所示

     grok {
       match => {
            "message" => [ "(?<timestamp>(\d){4}-(\d){2}-(\d){2} (\d){2}:(\d){2}:(\d){2}.(\d){3}) %{SYSLOG5424SD} ERROR u%{BASE16FLOAT}.%{JAVACLASS} - TransId:2b948ed5-12c0-4ae0-9b99-f1ee01191001 - TransactionId ::\"2b948ed5-12c0-4ae0-9b99-f1ee01191001\"- Actual Time taken to process \:\: %{NUMBER:responseTime:int}" ]
            } 

  }

date {
        match => [ "timestamp:date" , "yyyy-MM-dd HH:mm:ss.SSS Z"  ]
        timezone => "UTC"
        target => "@timestamp" 
         } 

但是，它并没有取代@timestamp 值，Json 值

{
  "_index": "logstash-2017.02.09",
  "_type": "logs",
  "_id": "AVoiZq2ITxwgj2avgkZa",
  "_score": null,
  "_source": {
    "path": "D:\\SoftsandTools\\Kibana\\Logs_ActualTimetakentoprocess.log",
    "@timestamp": "2017-02-09T10:23:58.778Z", …

我正在检查有没有办法使用 curl 清除rabbitmq 队列？我知道使用命令行，但我需要使用 curl 的东西？

建议/帮助表示赞赏

注意：-使用此链接，我没有得到要使用的确切 curl 命令

我正在尝试对目录下的所有日志文件执行 grep /var/log/application/archived/

而且我有 sudo 访问权限。像下面这样尝试给我错误

sudo grep 'checkThis' /var/log/application/archived/*.log

错误

grep: /var/log/application/archived/*.log: No such file or directory

我尝试使用转义字符，但似乎不起作用

如果我给出任何一个文件名而不是 * 它会给我结果。

例如：sudo grep 'checkThis' /var/log/application/archived/firstLogFile.log 这给了我预期的响应
