一：需求分析，创建数据库

导入sql文件

二：创建项目

1. create new Project
   
2. 左边选中Maven
3. 勾选Create from archetype
4. 选中 org.apache.maven.archetypes:maven-archetype-webapp
   
5. GroupId: 填写项目组的名字， ArtifactId: 填写项目的名字
6. 直接下一步
   
7. 确定路径，开工！
   
8. 可以开始打代码了
   

二：部署环境

1. 配置pom.xml

修改pom.xml为下面的代码，为了确保导入成功，右键点击pom.xml->Maven->Reimport

<?xml version="1.0" encoding="UTF-8"?><project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/POM/4.0.0

2. 配置基本的项目结构

（1）手动创建源代码目录

右键main目录-> New->Directory->输入java->右键java->Mark Directory as-> Sources Root


这样就创建了存放java源文件的目录了

（2）创建项目包

点中源目录：java 然后菜单->File->New->Package 输入 com.lh创建包

（3）创建bean包以及相关的实体类

根据自定义的数据库，创建每个表对应的实体类以及相关的属性、getXX()和setXX()方法

（4）创建mapper包以及每个实体类对应的mapper类

对每个实体类声明基本的增删改查的业务方法

（5）创建service包以及每个实体类对应的service接口

对每个实体类定义基本的增删改查的业务方法

（6）为service接口创建对应的实现类

在service包下创建impl包，用于存放实现类

（7）创建controller包以及网站每个功能对应的controller类

3. 配置属性文件

（1）手动创建配置目录

右键main目录-> New->Directory->输入resources->右键resources->Mark Directory as-> Resources Root

（2）配置mapper.xml文件

在resources目录下，新建mapper目录，为每个mapper类创建对应的mapper文件

（3）配置日志文件

在resources目录下新建log4j.properties

（4）配置数据库文件

在resources目录下新建jdbc.properties，此配置文件给出了访问数据库需要的必须信息

（5）配置spring

在resources目录下，新建spring目录，配置spring的数据库连接池、业务类注解的识别以及事务

（6）配置springMVC.xml

在resources目录下，新建springMVC目录，配置springMVC。开启注解的识别、开通静态资源的访问、视图定位、上传文件。

（7）配置web.xml

1. 指定spring的配置文件
2. 设置中文过滤器
3. 指定spring mvc配置文件
4. 文件上传

</web-app>

4. 导入静态资源

5. 设置测试类

右键main目录-> New->Directory->输入test->右键test->Mark Directory as-> Test Sources Root

三：配置Tomcat

1. 点击Run→点击 Edit Configurations→然后点击+号→选Tomcat Servet→Local
   
2. 点击Configure，选择Tomcat的路径
   
3. 点击Deployment→点击加号→点击Artifact→选择生成war包或自动解压，Application context要设置为你想要访问的路径
   

四：逆向工程生成代码

用逆向工程的方式，首先保证数据库里有表，然后通过Mybatis Generator生成bean, mapper和xml。

1. 在resources目录下，新建mybaits目录，配置generatorConfig.xml
   
   
2. 在test目录下编写GeneratorMybatis类并运行，自动生成

import org.junit.Before;
import org.junit.Test;
import org.mybatis.generator.api.MyBatisGenerator;
import org.mybatis.generator.config.Configuration;
import org.mybatis.generator.config.xml.ConfigurationParser;
import org.mybatis.generator.exception.InvalidConfigurationException;
import org.mybatis.generator.exception.XMLParserException;
import org.mybatis.generator.internal.DefaultShellCallback;import java.io.IOException;
import java.io.InputStream;
import java.sql.SQLException;
import java.util.ArrayList;
import java.util.List;public class GeneratorMybatis {private InputStream inputStream;@Beforepublic void before() throws IOException {inputStream = GeneratorMybatis.class.getClassLoader().getResource("mybatis/generatorConfig.xml").openStream();}@Testpublic void test() throws IOException, XMLParserException, InvalidConfigurationException, SQLException, InterruptedException {List<String> warnings = new ArrayList<>();boolean overwrite = true;ConfigurationParser parser = new ConfigurationParser(warnings);Configuration configuration = parser.parseConfiguration(inputStream);inputStream.close();DefaultShellCallback callback = new DefaultShellCallback(overwrite);MyBatisGenerator myBatisGenerator = new MyBatisGenerator(configuration,callback,warnings);myBatisGenerator.generate(null);System.out.println("success");}
}

3. 运行成功
   
   
   

五：运行成功
