在IDEA中一个项目创建后,还需要许多配置的过程,下面描述一下我自己的配置过程。
1. 完善目录结构
刚创建好的项目需要根据项目完善目录结构,我的目录结构如下

2.导入需要依赖的坐标
项目创建完毕后还需要导入许多依赖的包,这个项目中我导入的包如下,都是一些常用的包。
<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>

3.添加配置文件
在导入相关依赖的包之后需要添加配置文件,我的项目配置文件如下
image.png其中mybatis-config.xml是Mybatis的配置文件,applicationContext.xml是Web项目中Root WebApplicationContext容器的配置,webApplicationContext是DispatcherServlet中的相关配置,generator-config是相关的实体类生成插件的配置文件,log4j2是日志工具,datasource.properties是数据库配置文件。
3.1 datasource.properties数据库配置文件
jdbc.driver=com.mysql.cj.jdbc.Driver
jdbc.url=jdbc:mysql://127.0.0.1:3306/shop_erp?serverTimezone=Asia/Shanghai
jdbc.username=root
jdbc.password=root
3.2 mybatis-config.xml配置文件
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configuration
PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>

<settings>
<setting name="logImpl" value="LOG4J2"/>
</settings>
<typeAliases>

</typeAliases>
<plugins>
<plugin interceptor="com.github.pagehelper.PageInterceptor">
<!--使用对应数据库的分页-->
<property name="helperDialect" value="mysql"/>
<!--分页的页码为0时的,默认查询全部-->
<property name="pageSizeZero" value="true"/>
<!--分页的参数合理化,页码数字<0 默认查询第一页 页码数字>总页数 默认查询最后一页-->
<property name="reasonable" value="true"/>
</plugin>
</plugins>
</configuration>
3.3 log4j2.xml
<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="WARN">
<Appenders>
<Console name="Console" target="SYSTEM_OUT">
<PatternLayout pattern="%d{HH:mm:ss.SSS} [%t] %-5level %logger{36} - %msg%n" />
</Console>
</Appenders>
<Loggers>

4 用web容器加载Spring配置
在对相关文件配置完成后,需要在Web容器中加载相关的配置,即编辑WEB-INF目录下的web.xml文件。
配置内容如下
<?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">
<!--配置监听器(在项目启动后加载spring的配置文件创建IOC容器)-->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring/spring-mybatis.xml</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<!--配置SpringMVC的前端控制器-->
<servlet>
<servlet-name>SpringMVC</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring/spring-mvc.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>SpringMVC</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
<!--配置一个字符编码的过滤器-->
<filter>
<filter-name>encodingFilter</filter-name>
<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
<init-param>
<param-name>encoding</param-name>
<param-value>UTF-8</param-value>
</init-param>
<init-param>
<param-name>forceEncoding</param-name>
<param-value>true</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>encodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
</web-app>
