Java课程设计：校园导游系统
小編覺(jué)得挺不錯(cuò)的,現(xiàn)在分享給大家,幫大家做個(gè)參考.
校園導(dǎo)游系統(tǒng)

- 設(shè)計(jì)要求
- 功能模塊分析

- 數(shù)據(jù)庫(kù)連接
- 數(shù)據(jù)庫(kù)功能的實(shí)現(xiàn)

內(nèi)容目錄：
1. 設(shè)計(jì)要求 2. 功能分析設(shè)計(jì)要求
圖形化界面（GUI），編寫一個(gè)文本文件信息統(tǒng)計(jì)軟件 （１）顯示打開文件的基本信息（文件名、路徑、文件大小、最后修改日期） （２）顯示文件內(nèi)容統(tǒng)計(jì)信息（行、字/單詞數(shù)） （３）顯示文件內(nèi)容 （４）按照文件大小或最后修改時(shí)間排序 （５）按照文件名或者文件內(nèi)容包含關(guān)鍵字模糊查詢功能模塊分析
1. 數(shù)據(jù)庫(kù)設(shè)計(jì)2. gui設(shè)計(jì)3. 數(shù)據(jù)庫(kù)連接4. 數(shù)據(jù)庫(kù)相關(guān)功能實(shí)現(xiàn)數(shù)據(jù)庫(kù)設(shè)計(jì)
1. 有校園建筑表校園建筑表 schooladd
CREATE TABLE `schooladd` (`id` int(11) NOT NULL AUTO_INCREMENT COMMENT 'primary key',`sname` varchar(20) DEFAULT NULL,`x` int(100) DEFAULT NULL,`y` int(100) DEFAULT NULL,PRIMARY KEY (`id`) ) ENGINE=InnoDB AUTO_INCREMENT=4 DEFAULT CHARSET=utf8 2. 有校園建筑信息表校園建筑信息表
CREATE TABLE `message` (`id` int(10) NOT NULL,`name` varchar(255) DEFAULT NULL,`message` varchar(255) DEFAULT NULL,PRIMARY KEY (`id`) ) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_0900_ai_ci數(shù)據(jù)庫(kù)連接
利用jdbc，util和資源文件來(lái)連接數(shù)據(jù)庫(kù)JdbcUtil.java如下
package com.datasource.utils;import com.alibaba.druid.pool.DruidDataSourceFactory;import javax.sql.DataSource; import java.sql.Connection; import java.sql.ResultSet; import java.sql.SQLException; import java.sql.Statement; import java.util.Properties;public class JdbcUtils {/*** 1. 定義成員變量DataSourse*/private static DataSource ds;static {try {//1. 加載配置文件Properties pro = new Properties();pro.load(JdbcUtils.class.getClassLoader().getResourceAsStream("druid.properties"));//2.獲取DataSourceds = DruidDataSourceFactory.createDataSource(pro);} catch (Exception e) {e.printStackTrace();}}/*** 獲取資源* @return ds.getConnection()*/public static Connection getConnection() throws SQLException{return ds.getConnection();}/*** 釋放資源*/public static void close(ResultSet rs, Statement stmt, Connection conn){if (rs != null){try {rs.close();} catch (SQLException e) {e.printStackTrace();}}if (stmt != null){try {stmt.close();} catch (SQLException e) {e.printStackTrace();}}if (conn != null){try {conn.close();} catch (SQLException e) {e.printStackTrace();}}}/*** 獲取連接池方法* @return ds*/public static DataSource getDataSource(){return ds;} }配置文件druid.properties如下：

數(shù)據(jù)庫(kù)功能的實(shí)現(xiàn)
通過(guò)JdbcTemplate和Jdbc來(lái)實(shí)現(xiàn)數(shù)據(jù)庫(kù)相關(guān)功能JdbcTemplate.java
