1. System requirements analysis
1.1 Overview of Requirements
DMS data mining project is a system based on C/S (Client/Server, client/server) architecture.
1.2 Requirements Description
It consists of two parts: DMS client and DMS server:
●DMS client is a part of the system, its main task is to collect, analyze and match the data, and send the matched data to the DMS server.
●The DMS server is used to receive the data sent by the DMS client and save the data in the database. The DMS server provides monitoring functions for the received data.
2. Overall system design
2.1 Purpose of writing
The DMS data mining project can collect various data types, such as the collection of log data information, logistics data information collection, etc., and various data information are based on inheritance relationships.
2.2 Overall Design
2.2.1 Function division
2.2.2 Database and tables
2.2.3 Main business process
3. Detailed design and implementation
3.1 Table Design
user table
match log table
Match logistics table
The DataTableModelFromList class implements the function of reading log or logistics data from a file, and then displaying the data in the form of a table.
package com.qst.dms.entity;
import javax.swing.table.AbstractTableModel;
import java.util.ArrayList;
import java.util.List;
public class DataTableModelFromList<T> extends AbstractTableModel {
// 使用List来创建TableModel
private List<String[]> datas = new ArrayList<>();
// 标志位，区分日志和物流：1，日志；0，物流
private int sign;
public DataTableModelFromList(List<T> data, int sign) {
// TODO Auto-generated constructor stub
this.sign = sign;
for(T obj: data) {
try {
String[] arr = (String[])obj.getClass().getMethod("toArray").invoke(obj);
datas.add(arr);
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
// 获取表格的行数
public int getRowCount() {
return datas.size();
}
// 获取表格的列数
public int getColumnCount() {
return this.sign==1?7:7;
}
// 获取指定位置的值
public Object getValueAt(int rowIndex, int columnIndex) {
return datas.get(rowIndex)[columnIndex];
}
// 获取表头信息
public String getColumnName(int column) {
String[] logArray = {
"日志ID", "采集时间", "采集地点", "状态", "用户名", "IP", "日志类型" };
String[] tranArray = {
"物流ID", "采集时间", "目的地", "状态", "经手人", "收货人",
"物流类型" };
return sign == 1 ? logArray[column] : tranArray[column];
}
}
The MatchedTableModel class realizes the function of reading log or logistics data from the database, and then displaying the data in the form of a table.
package com.qst.dms.entity;
import javax.swing.table.AbstractTableModel;
import java.sql.ResultSet;
import java.sql.ResultSetMetaData;
public class MatchedTableModel extends AbstractTableModel {
// 使用ResultSet来创建TableModel
private ResultSet rs;
private ResultSetMetaData rsmd;
// 标志位，区分日志和物流：1，日志；0，物流
private int sign;
public MatchedTableModel(ResultSet rs, int sign) {
this.rs = rs;
this.sign = sign;
try {
rsmd = rs.getMetaData();
} catch (Exception e) {
rsmd = null;
}
}
// 获取表格的行数
public int getRowCount() {
try {
rs.last();
// System.out.println(count);
return rs.getRow();
} catch (Exception e) {
return 0;
}
}
// 获取表格的列数
public int getColumnCount() {
try {
// System.out.println(rsmd.getColumnCount());
return rsmd.getColumnCount();
} catch (Exception e) {
return 0;
}
}
// 获取指定位置的值
public Object getValueAt(int rowIndex, int columnIndex) {
try {
rs.absolute(rowIndex + 1);
return rs.getObject(columnIndex + 1);
} catch (Exception e) {
return null;
}
}
// 获取表头信息
public String getColumnName(int column) {
String[] logArray = {
"日志ID", "采集时间", "采集地点", "状态", "用户名", "IP", "日志类型" };
String[] tranArray = {
"物流ID", "采集时间", "目的地", "状态", "经手人", "收货人",
"物流类型" };
return sign == 1 ? logArray[column] : tranArray[column];
}
}
3.2 Design of database access tools
The DBUtil class realizes the simple operation of connecting to the database and performing transaction processing.
package com.qst.dms.util;
import java.sql.*;
public class DBUtil {
static Connection conn = null;
PreparedStatement pstmt = null;
ResultSet rs = null;
/**
* 得到数据库连接
*/
public static Connection getConnection() throws ClassNotFoundException,
SQLException, InstantiationException, IllegalAccessException {
// 通过Config获取Mysql数据库配置信息
String driver = Config.getValue("driver");
String url = Config.getValue("url");
String user = Config.getValue("user");
String pwd = Config.getValue("password");
// 指定驱动程序
Class.forName(driver);
// 建立数据库连结
conn = DriverManager.getConnection(url, user, pwd);
conn.setAutoCommit(false);//----------
return conn;
}
//手动提交事务
public void commitAll() {
try {
if(conn!=null&&!conn.isClosed())
conn.commit();
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
//手动回滚事务
public void rollbackAll() {
try {
if(conn!=null&&!conn.isClosed())
conn.rollback();
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
/**
* 释放资源
*/
public void closeAll() {
// 如果rs不空，关闭rs
if (rs != null) {
try {
rs.close();
} catch (SQLException e) {
e.printStackTrace();
}
}
// 如果pstmt不空，关闭pstmt
if (pstmt != null) {
try {
pstmt.close();
} catch (SQLException e) {
e.printStackTrace();
}
}
// 如果conn不空，关闭conn
if (conn != null) {
try {
conn.close();
} catch (SQLException e) {
e.printStackTrace();
}
}
}
/**
* 执行SQL语句，可以进行查询
*/
public ResultSet executeQuery(String preparedSql, Object[] param) {
// 处理SQL,执行SQL
try {
// 得到PreparedStatement对象
pstmt = conn.prepareStatement(preparedSql);
if (param != null) {
for (int i = 0; i < param.length; i++) {
// 为预编译sql设置参数
pstmt.setObject(i + 1, param[i]);
}
}
// 执行SQL语句
rs = pstmt.executeQuery();
} catch (SQLException e) {
// 处理SQLException异常
e.printStackTrace();
}
return rs;
}
/**
* 执行SQL语句，可以进行增、删、改的操作，不能执行查询
*/
public int executeUpdate(String preparedSql, Object[] param) {
int num = 0;
// 处理SQL,执行SQL
try {
// 得到PreparedStatement对象
pstmt = conn.prepareStatement(preparedSql);
if (param != null) {
for (int i = 0; i < param.length; i++) {
// 为预编译sql设置参数
pstmt.setObject(i + 1, param[i]);
}
}
// 执行SQL语句
num = pstmt.executeUpdate();
} catch (SQLException e) {
if (e instanceof SQLIntegrityConstraintViolationException) {
System.out.println("主键冲突，跳过当前记录");
return 0;
} else {
// 处理其他SQL异常
e.printStackTrace();
}
}
return num;
}
}
3.3 Configuration file
mysql.properties is as follows, which saves the configuration data of the database
driver = com.mysql.cj.jdbc.Driver
url = jdbc:mysql://localhost:3306/数据库名?serverTimezone=Asia/Shanghai&useSSL=false&useUnicode=true&characterEncoding=utf-8
user = ****
password = ******
client.properties saves the configuration of the client
host=******
port=******
server.properties saves the configuration of the server
port=******

3.6 Exception handling
There are many exception handling structures in the project. For example, when the user name entered by the user during registration already exists, a warning message "User name already exists" will be prompted; when the user enters the same id when entering data on the client, it will be prompted "same id" warning message, and prompt the user to re-enter the information, etc.
