在Maven项目中，配置依赖和测试依赖通常如下所示：

xml junit junit 4.13.2 test mysql mysql-connector-java 版本号 com.alibaba druid 版本号 javax.servlet javax.servlet-api 版本号 provided javax.servlet.jsp javax.servlet.jsp-api 版本号 provided org.mybatis mybatis 版本号 org.mybatis mybatis-spring 版本号 org.springframework spring-context 版本号 org.springframework spring-webmvc 版本号

一、Maven依赖

<!--依赖： junit，数据库驱动，连接池，Servlet，jsp，MyBatis，MyBatis-spring，spring--> <dependencies> <!-- junit测试 --> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.13.2</version> <scope>test</scope> </dependency> <!-- MySQL驱动 --> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>8.0.27</version> </dependency> <!-- 数据库连接池 --> <!-- mvnrepository.com/artifact/com.alibaba/druid --> <dependency> <groupId>com.alibaba</groupId> <artifactId>druid</artifactId> <version>1.1.9</version> </dependency> <!--Servlet JSP --> <!-- mvnrepository.com/artifact/javax.servlet/javax.servlet-api --> <dependency> <groupId>javax.servlet</groupId> <artifactId>javax.servlet-api</artifactId> <version>3.1.0</version> </dependency> <!-- mvnrepository.com/artifact/javax.servlet/jsp-api --> <dependency> <groupId>javax.servlet</groupId> <artifactId>jsp-api</artifactId> <version>2.0</version> </dependency> <dependency> <groupId>jstl</groupId> <artifactId>jstl</artifactId> <version>1.2</version> </dependency> <!--MyBatis--> <!-- MyBatis核心依赖包 --> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis</artifactId> <version>3.5.9</version> </dependency> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis-spring</artifactId> <version>2.0.7</version> </dependency> <!--Spring--> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>5.3.16</version> </dependency> <!--Spring要操作数据库，还需要一个spring-jdbc--> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> <version>5.3.16</version> </dependency> <dependency> <groupId>org.aspectj</groupId> <artifactId>aspectjweaver</artifactId> <version>1.9.9</version> </dependency> <dependency> <groupId>org.projectlombok</groupId> <artifactId>lombok</artifactId> <version>1.16.10</version> </dependency> <!--log4j日志--> <dependency> <groupId>log4j</groupId> <artifactId>log4j</artifactId> <version>1.2.17</version> </dependency> <!-- slf4j日志门面的一个具体实现 --> <dependency> <groupId>ch.qos.logback</groupId> <artifactId>logback-classic</artifactId> <version>1.2.3</version> </dependency> </dependencies> 二、各类配置文件 1、web.xml

<?xml version="1.0" encoding="UTF-8"?> <web-app xmlns="xmlns.jcp.org/xml/ns/javaee" xmlns:xsi="www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="xmlns.jcp.org/xml/ns/javaee xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd" version="4.0"> <!--DispatcherServlet配置--> <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:applicationContext.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> <!--encodingFilter，解决字符集乱码问题--> <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> </filter> <filter-mapping> <filter-name>encodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> </web-app> 2、mybatis-config.xml

<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN" "mybatis.org/dtd/mybatis-3-config.dtd"> <configuration> <!-- MyBatis核心配置文件中，标签的顺序 properties?,settings?,typeAliases?,typeHandlers?, objectFactory?,objectWrapperFactory?,reflectorFactory?, plugins?,environments?,databaseIdProvider?,mappers --> <!--设置类型别名，name值为bean包（pojo包）--> <typeAliases> <package name=""/> </typeAliases> <!--引入映射文件，name值为dao层（mapper层）--> <mappers> <package name=""/> </mappers> </configuration> 3、jdbc.properties

##数据库连接驱动 jdbc.driver=com.mysql.cj.jdbc.Driver ##数据库连接，db为数据库名 jdbc.url=jdbc:mysql://localhost:3306/db?characterEncoding=utf-8 jdbc.username= jdbc.password= 4、spring-dao.xml

<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="www.springframework.org/schema/beans" xmlns:xsi="www.w3.org/2001/XMLSchema-instance" xmlns:context="www.springframework.org/schema/context" xsi:schemaLocation="www.springframework.org/schema/beans www.springframework.org/schema/beans/spring-beans.xsd www.springframework.org/schema/context www.springframework.org/schema/context/spring-context.xsd"> <!--1、关联数据库配置文件--> <context:property-placeholder location="classpath:jdbc.properties"/> <!--2、连接池 dbcp: 半自动化操作，不能自动连接 c3p0: 自动化操作（自动化地加载配置文件，并且可以自动设置到对象中） druid: hikari: --> <!--这里使用druid--> <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource"> <property name="driverClassName" value="${jdbc.driver}"></property> <property name="url" value="${jdbc.url}"></property> <property name="username" value="${jdbc.username}"></property> <property name="password" value="${jdbc.password}"></property> </bean> <!--3、SQLSessionFactory--> <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <property name="dataSource" ref="dataSource" /> <!--绑定MyBatis配置文件--> <property name="configLocation" value="classpath:mybatis-config.xml"></property> </bean> <!--配置dao接口扫描包，动态实现了dao接口可以注入到Spring容器--> <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <!--注入sqlSessionFactory--> <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/> <!--扫描到dao包，value值为要扫描到的包--> <property name="basePackage" value=""/> </bean> </beans> 5、spring-service.xml

<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="www.springframework.org/schema/beans" xmlns:xsi="www.w3.org/2001/XMLSchema-instance" xmlns:context="www.springframework.org/schema/context" xsi:schemaLocation="www.springframework.org/schema/beans www.springframework.org/schema/beans/spring-beans.xsd www.springframework.org/schema/context www.springframework.org/schema/context/spring-context.xsd www.springframework.org/schema/aop www.springframework.org/schema/aop/spring-aop.xsd"> <!--1、扫描service下的包，base-package值为要扫描包--> <context:component-scan base-package=""></context:component-scan> <!--2、将我们的所有业务类，注入到Spring，可以通过配置，或者注解实现--> <bean id="" class=""> <property name="" ref=""/> </bean> <!--3、声明式事务配置--> <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <!--注入数据源--> <property name="dataSource" ref="dataSource"/> </bean> </beans> 6、spring-mvc.xml

<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="www.springframework.org/schema/beans" xmlns:xsi="www.w3.org/2001/XMLSchema-instance" xmlns:context="www.springframework.org/schema/context" xmlns:mvc="www.springframework.org/schema/mvc" xsi:schemaLocation="www.springframework.org/schema/beans www.springframework.org/schema/beans/spring-beans.xsd www.springframework.org/schema/context www.springframework.org/schema/context/spring-context.xsd www.springframework.org/schema/mvc www.springframework.org/schema/mvc/spring-mvc.xsd"> <!--1、注解驱动--> <mvc:annotation-driven/> <!--2、静态资源过滤--> <mvc:default-servlet-handler/> <!--3、扫描包：controller，base-package值为要扫描的包--> <context:component-scan base-package=""/> <!--4、视图解析器--> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/WEB-INF/jsp/"/> <property name="suffix" value=".jsp"/> </bean> </beans> 7、applicationContext.xml

<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="www.springframework.org/schema/beans" xmlns:xsi="www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="www.springframework.org/schema/beans www.springframework.org/schema/beans/spring-beans.xsd"> <!--将前三个xml配置整合--> <import resource="classpath:spring-dao.xml"/> <import resource="classpath:spring-service.xml"/> <import resource="classpath:spring-mvc.xml"/> </beans> 8、log4j.xml

log4j报红可以不用管，也可自行查询解决方法

<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE log4j:configuration SYSTEM "log4j.dtd"> <log4j:configuration xmlns:log4j="jakarta.apache.org/log4j/"> <appender name="STDOUT" class="org.apache.log4j.ConsoleAppender"> <param name="Encoding" value="UTF-8" /> <layout class="org.apache.log4j.PatternLayout"> <param name="ConversionPattern" value="%-5p %d{MM-dd HH:mm:ss,SSS} %m (%F:%L) \n" /> </layout> </appender> <logger name="java.sql"> <level value="debug" /> </logger> <logger name="org.apache.ibatis"> <level value="info" /> </logger> <root> <level value="debug" /> <appender-ref ref="STDOUT" /> </root> </log4j:configuration> 9、logback.xml

<?xml version="1.0" encoding="UTF-8"?> <configuration debug="true"> <!-- 指定日志输出的位置 --> <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender"> <encoder> <!-- 日志输出的格式 --> <!-- 按照顺序分别是：时间、日志级别、线程名称、打印日志的类、日志主体内容、换行 --> <pattern>[%d{HH:mm:ss.SSS}] [%-5level] [%thread] [%logger] [%msg]%n</pattern> </encoder> </appender> <!-- 设置全局日志级别。日志级别按顺序分别是：DEBUG、INFO、WARN、ERROR --> <!-- 指定任何一个日志级别都只打印当前级别和后面级别的日志。 --> <root level="DEBUG"> <!-- 指定打印日志的appender，这里通过“STDOUT”引用了前面配置的appender --> <appender-ref ref="STDOUT" /> </root> <!-- 根据特殊需求指定局部日志级别，dao层（mapper层） --> <logger name="" level="DEBUG"/> </configuration>
