升级到0.6.1后,ActiveAdmin仪表板不再有效.仪表板现在返回错误:

  /app/app/admin/dashboards.rb:1:in `<top (required)>': uninitialized constant ActiveAdmin::Dashboards (NameError) 

更新已解决:

仪表板已从ActiveAdmin 0.6.1中删除.要继续使用仪表板,请在应用程序的Gemfile中强制使用0.6.0版:

 gem "activeadmin", "0.6.0"

我有这个名为Person的类对象

public class Person {
    ....
    private List<Person> people;
    ....
    public List<Person> getPeople() {
          return people;
    }

    public void setPeople(List<Person> people) {
          this.people = people;
    }

每个人都有里面所有员工的名单,每个人都有下面的人员名单.如何找到最大深度？例如,在该图像中,最大深度为2.第二高度为1.任何帮助都是值得赞赏的.

我的瘦服务器在30秒后超时.我想覆盖这个ruby文件.

DEFAULT_TIMEOUT从30秒到120秒.怎么做？请告诉我.

代码在这里:https: //github.com/macournoyer/thin/blob/master/lib/thin/server.rb

我想覆盖没有"已经初始化的常量"警告.

我用MyBatis创建了Spring MVC 4.我很确定我的设置都正确.出于某种原因,我收到了这个错误.任何帮助表示赞赏

我尝试通过SFTP删除非空文件夹的JSCH,但它没有用.

这个有效,但它不是免费的:(我已经过了30天的试用期.我的公司拒绝支付它们只是通过SFTP删除文件夹.

package com.test.cvsutil;

import java.util.List;

import org.apache.log4j.Logger;

import com.jscape.inet.sftp.Sftp;
import com.jscape.inet.sftp.SftpException;
import com.jscape.inet.sftp.events.SftpAdapter;
import com.jscape.inet.ssh.util.SshParameters;

public class SFTPFileDeleter extends SftpAdapter {
     static String hostName = ServerProperties.getProperty("test.ftp.hostname");
     static String username = ServerProperties.getProperty("test.ftp.login");
     static String password = ServerProperties.getProperty("test.ftp.password");
     static String directory = ServerProperties.getProperty("test.ftp.directory");
    private static Sftp sftp;

    private static org.apache.log4j.Logger log = Logger.getLogger(SFTPFileDeleter.class);


    public static boolean deleteDir(List <String> path) throws SftpException {
        Boolean flag = false;
        log.info("------------------------ file(s) delete started ------------------------");
        sftp = new Sftp(new SshParameters(hostName, username, password));

        sftp.connect();
        sftp.setDir(directory);
