JavaWeb24（SMBMS项目搭建01）

项目搭建

1.搭建一个maven项目

• 新建一个项目 以webapp为模板
  
  
• 完善项目，在main包下创建java和resources包；把web.xml用Tomcat中的最新版代替

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee
                      http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd"
         version="4.0"
         metadata-complete="true">


</web-app>

2.配置Tomcat

3.测试项目是否能启动

启动成功

4.导入目前需要的jar包

<dependencies>
    <dependency>
        <groupId>javax.servlet</groupId>
        <artifactId>servlet-api</artifactId>
        <version>2.5</version>
    </dependency>

    <dependency>
        <groupId>javax.servlet.jsp</groupId>
        <artifactId>jsp-api</artifactId>
        <version>2.1</version>
    </dependency>

    <dependency>
        <groupId>javax.servlet.jsp.jstl</groupId>
        <artifactId>jstl-api</artifactId>
        <version>1.2</version>
    </dependency>
    
    <dependency>
        <groupId>taglibs</groupId>
        <artifactId>standard</artifactId>
        <version>1.1.2</version>
    </dependency>

    <dependency>
        <groupId>mysql</groupId>
        <artifactId>mysql-connector-java</artifactId>
        <version>5.1.47</version>
    </dependency>
</dependencies>

5.创建项目包结构

6. 编写实体类

• ORM映射 类-表映射

• 连接mysql
  
  
  （需要数据库连接依赖；首次连接需要先下载mysql驱动，IDEA中会会有提示，点击下载即可）

• 导入需要的库
  

• mysql代码

7.编写基础公共类

1.数据库配置文件

在resources下创建一个db.properties file

driver=com.mysql.jdbc.Driver
url=jdbc:mysql://localhost:3306?useUnicode=true&characterEncoding=utf-8
username=root
password=Zyh0426.

2.编写数据库公共类

package com.hao.dao;

import java.io.IOException;
import java.io.InputStream;
import java.sql.*;
import java.util.Properties;

public class BaseDao {
    
    
    private static String driver;
    private static String url;
    private static String username;
    private static String password;

    //静态代码块，类加载的时候就已经初始化
    static {
    
    
        Properties properties = new Properties();
        InputStream resourceAsStream = BaseDao.class.getClassLoader().getResourceAsStream("db.properties");
        try {
    
    
            properties.load(resourceAsStream);
        } catch (IOException e) {
    
    
            e.printStackTrace();
        }
        driver = properties.getProperty("driver");
        url = properties.getProperty("url");
        username = properties.getProperty("username");
        password = properties.getProperty("password");
    }

    //获取数据库连接
    public static Connection getConnection(){
    
    
        Connection connection = null;
        try {
    
    
            Class.forName(driver);
            connection = DriverManager.getConnection(url,username,password);
        } catch (Exception e) {
    
    
            e.printStackTrace();
        }
        return connection;
    }
    //编写查询公共类方法
    public static ResultSet execute(Connection connection,String sql, Object[] params,ResultSet resultSet,PreparedStatement preparedStatement) throws SQLException {
    
    
        //预编译的sql，在后面直接执行就行
        preparedStatement = connection.prepareStatement(sql);
        for (int i = 0; i < params.length; i++) {
    
    
            //setObject,占位符从1开始，数组从0开始 所以要+1
            preparedStatement.setObject(i+1,params[i]);
        }
        resultSet=preparedStatement.executeQuery();
        return resultSet;
    }

    //编写增删改公共类
    public static int execute(Connection connection,String sql, Object[] params,PreparedStatement preparedStatement) throws SQLException {
    
    
        preparedStatement = connection.prepareStatement(sql);
        for (int i = 0; i < params.length; i++) {
    
    
            //setObject,占位符从1开始，数组从0开始 所以要+1
            preparedStatement.setObject(i+1,params[i]);
        }
        int updateRows=preparedStatement.executeUpdate( );
        return updateRows;
    }

    //关闭连接，释放资源
    public static boolean closeResources(Connection connection, PreparedStatement preparedStatement,ResultSet resultSet){
    
    
        boolean flag = true;
        if (resultSet!=null){
    
    
            try {
    
    
                resultSet.close();
                //设置为空，GC自动回收
                resultSet=null;
            } catch (SQLException throwables) {
    
    
                throwables.printStackTrace();
                //关闭失败
                flag=false;
            }
        }
        if (connection!=null){
    
    
            try {
    
    
                connection.close();
                //设置为空，GC自动回收
                connection=null;
            } catch (SQLException throwables) {
    
    
                throwables.printStackTrace();
                //关闭失败
                flag=false;
            }
        }
        if (preparedStatement!=null){
    
    
            try {
    
    
                preparedStatement.close();
                //设置为空，GC自动回收
                preparedStatement=null;
            } catch (SQLException throwables) {
    
    
                throwables.printStackTrace();
                //关闭失败
                flag=false;
            }
        }
        return  flag;
    }
    
}

3.编写字符编码过滤器

CharacterEncodingFilter.java

package com.hao.dao;

import java.io.IOException;
import java.io.InputStream;
import java.sql.*;
import java.util.Properties;

public class BaseDao {
    
    
    private static String driver;
    private static String url;
    private static String username;
    private static String password;

    //静态代码块，类加载的时候就已经初始化
    static {
    
    
        Properties properties = new Properties();
        InputStream resourceAsStream = BaseDao.class.getClassLoader().getResourceAsStream("db.properties");
        try {
    
    
            properties.load(resourceAsStream);
        } catch (IOException e) {
    
    
            e.printStackTrace();
        }
        driver = properties.getProperty("driver");
        url = properties.getProperty("url");
        username = properties.getProperty("username");
        password = properties.getProperty("password");
    }

    //获取数据库连接
    public static Connection getConnection(){
    
    
        Connection connection = null;
        try {
    
    
            Class.forName(driver);
            connection = DriverManager.getConnection(url,username,password);
        } catch (Exception e) {
    
    
            e.printStackTrace();
        }
        return connection;
    }
    //编写查询公共类方法
    public static ResultSet execute(Connection connection,String sql, Object[] params,ResultSet resultSet,PreparedStatement preparedStatement) throws SQLException {
    
    
        //预编译的sql，在后面直接执行就行
        preparedStatement = connection.prepareStatement(sql);
        for (int i = 0; i < params.length; i++) {
    
    
            //setObject,占位符从1开始，数组从0开始 所以要+1
            preparedStatement.setObject(i+1,params[i]);
        }
        resultSet=preparedStatement.executeQuery();
        return resultSet;
    }

    //编写增删改公共类
    public static int execute(Connection connection,String sql, Object[] params,PreparedStatement preparedStatement) throws SQLException {
    
    
        preparedStatement = connection.prepareStatement(sql);
        for (int i = 0; i < params.length; i++) {
    
    
            //setObject,占位符从1开始，数组从0开始 所以要+1
            preparedStatement.setObject(i+1,params[i]);
        }
        int updateRows=preparedStatement.executeUpdate( );
        return updateRows;
    }

    //关闭连接，释放资源
    public static boolean closeResources(Connection connection, PreparedStatement preparedStatement,ResultSet resultSet){
    
    
        boolean flag = true;
        if (resultSet!=null){
    
    
            try {
    
    
                resultSet.close();
                //设置为空，GC自动回收
                resultSet=null;
            } catch (SQLException throwables) {
    
    
                throwables.printStackTrace();
                //关闭失败
                flag=false;
            }
        }
        if (connection!=null){
    
    
            try {
    
    
                connection.close();
                //设置为空，GC自动回收
                connection=null;
            } catch (SQLException throwables) {
    
    
                throwables.printStackTrace();
                //关闭失败
                flag=false;
            }
        }
        if (preparedStatement!=null){
    
    
            try {
    
    
                preparedStatement.close();
                //设置为空，GC自动回收
                preparedStatement=null;
            } catch (SQLException throwables) {
    
    
                throwables.printStackTrace();
                //关闭失败
                flag=false;
            }
        }
        return  flag;
    }
    
}

并在web.xml中配置

<!--字符编码过滤器-->
<filter>
    <filter-name>CharacterEncodingFilter</filter-name>
    <filter-class>com.hao.filter.CharacterEncodingFilter</filter-class>
</filter>
    <filter-mapping>
        <filter-name>CharacterEncodingFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

8.导入静态资源

把静态资源放在webapp包下
gitee上搜SMBMS就有
