Java爬虫_爬虫项目

一：介绍：本文会介绍一个完整的爬虫项目，并打包成windows可执行程序
1.1、效果图：

二：开发：
2.1、创建一个Maven项目“demo”
2.2、pom.xml中添加项目依赖

                        setDate(c.getTime());
                        return;
                  }
                  else if(source.getName().equals("Second")){
                  c.set(Calendar.SECOND, getSelectedSecond());
                        setDate(c.getTime());
                        return;
                  }


                  dayColorUpdate(true);


                  if (source.getName().equals("Year"))
                        c.set(Calendar.YEAR, getSelectedYear());
                  else
                        // (source.getName().equals("Month"))
                        c.set(Calendar.MONTH, getSelectedMonth() - 1);
                  setDate(c.getTime());
                  flushWeekAndDay();
            }


            public void actionPerformed(ActionEvent e) {
                  JButton source = (JButton) e.getSource();
                  if (source.getText().length() == 0) return;
                  dayColorUpdate(true);
                  source.setForeground(todayBackColor);
                  int newDay = Integer.parseInt(source.getText());
                  Calendar c = getCalendar();
                  c.set(Calendar.DAY_OF_MONTH, newDay);
                  setDate(c.getTime());
            }


      }


}

6、ConfigHelper.java(配置文件获取类)
package CaililiangTools;

import java.io.*;
import java.net.URISyntaxException;
import java.util.HashMap;
import java.util.Properties;

public class ConfigHelper {
    public HashMap<String,String> getUserInfo() {
        HashMap<String,String> returnMap = new HashMap<String,String>();
        try{
            Properties properties = new Properties();
            InputStream in = new BufferedInputStream(new FileInputStream("C:\\Users\\Administrator\\Desktop\\UserInfo.properties"));
            properties.load(new InputStreamReader(in, "utf-8"));
            String userName = properties.getProperty("userName");
            String passWord = properties.getProperty("passWord");
            returnMap.put("userName",userName);
            returnMap.put("passWord",passWord);
        }catch (IOException e){
            System.err.println("UserInfo.properties文件读取失败");
            System.err.println("UserInfo.properties文件必须放在windows桌面上");
        }
        return returnMap;
    }
    public Properties getEmailUserInfos() {
        Properties properties=null;
        HashMap<String,String> returnMap = new HashMap<String,String>();
        try{
            properties = new Properties();
            InputStream in =  new BufferedInputStream(new FileInputStream("C:\\Users\\Administrator\\Desktop\\EmaiUserInfos.properties"));
            properties.load(new InputStreamReader(in, "utf-8"));
        }catch (IOException e){
            System.err.println("EmaiUserInfos.properties文件读取失败");
            System.err.println("EmaiUserInfos.properties文件必须放在windows桌面上");
        }
        return properties;
    }
}

四、jar包装成EXE可执行程序（exe4j工具）
参照我的另一篇文章：https://www.jianshu.com/p/bfad27d7812d

五、exe文件打包成可安装程序（inno setup工具）
参照我的另一篇文章：https://www.jianshu.com/p/63b2605ee2b4
