struts2框架搭建

1.新建javaweb项目，命名为S2并创建包，导入jar包

2.db.properties:

url=jdbc:mysql://localhost:8080/sshtest
type=mysql
user=root

psw=root

3.web.xml:

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">

</web-app>

4.DbInt：

package com.util;


import java.sql.Connection;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.Statement;


public interface DbInt {
public Connection getConncetion();


public void closeConnection(Connection conn);


public void close(PreparedStatement pstate, Statement state, ResultSet rs);

}

String url = prop.getProperty("url");
String user = prop.getProperty("user");
String psw = prop.getProperty("psw");
switch (prop.getProperty("type")) {
case "mysql":
Class.forName("com.mysql.jdbc.Driver");//加载驱动
conn = DriverManager.getConnection(url, user, psw);// 建立连接;
break;
default:
System.out.println("数据库配置文件错误！");
break;

prop.clear();
in.close();
} catch (IOException | ClassNotFoundException | SQLException e) {
// TODO Auto-generated catch block
