1、file-->new-->project-->maven....
2、建立后的目录：
3、pom.xml依赖建立：
<?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

4、web.xml
<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd" > <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" version="3.0"> <welcome-file-list> <welcome-file>index.html</welcome-file> <welcome-file>index.htm</welcome-file> <welcome-file>index.jsp</welcome-file> <welcome-file>default.html</welcome-file> <welcome-file>default.htm</welcome-file> <welcome-file>default.jsp</welcome-file> </welcome-file-list> <!-- 初始化spring容器 --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring/applicationContext-*.xml</param-value> </context-param> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!-- 配置logback --> <context-param> <param-name>logbackConfigLocation</param-name> <param-value>classpath:logback.xml</param-value> </context-param> <!-- 解决post乱码 --> <filter> <filter-name>CharacterEncodingFilter</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>CharacterEncodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!-- spring-mvc的前端控制器 --> <servlet> <servlet-name>ssmproject</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <!-- spring-mvc的配置文件默认在：WEB-INF/servlet的name+"-servlet.xml" --> <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>ssmproject</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> </web-app>
5、lockback.xml

6、db.properties(基于c3p0)
# mysql数据库 jdbc.driver=com.mysql.cj.jdbc.Driver <!--上面和下面似乎都是因为驱动和mysql版本（8）不匹配出现的问题--!> # 本地mysql数据库 jdbc.url=jdbc:mysql://localhost:3306/ssmproject?characterEncoding=utf-8&useSSL=false&serverTimezone = GMT jdbc.username=root jdbc.password=root #最大连接数 c3p0.maxPoolSize=30 #最小连接数 c3p0.minPoolSize=10 #关闭连接后不自动commit c3p0.autoCommitOnClose=false #获取连接超时时间 c3p0.checkoutTimeout=10000 #当获取连接失败重试次数 c3p0.acquireRetryAttempts=2
7、applicationContext-dao.xml
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:context="http://www.springframework.org/schema/context" xmlns:p="http://www.springframework.org/schema/p" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-4.0.xsd"> <!-- 加载配置文件 --> <context:property-placeholder location="classpath:properties/*.properties" /> <!-- 数据库连接池 --> <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"> <property name="driverClass" value="${jdbc.driver}"/> <property name="jdbcUrl" value="${jdbc.url}"/> <property name="user" value="${jdbc.username}"/> <property name="password" value="${jdbc.password}"/> <property name="maxPoolSize" value="${c3p0.maxPoolSize}"/> <property name="minPoolSize" value="${c3p0.minPoolSize}"/> <property name="autoCommitOnClose" value="${c3p0.autoCommitOnClose}"/> <property name="checkoutTimeout" value="${c3p0.checkoutTimeout}"/> <property name="acquireRetryAttempts" value="${c3p0.acquireRetryAttempts}"/> </bean> <!-- 让spring管理sqlSessionFactory --> <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <property name="dataSource" ref="dataSource" /> <!-- 加载mybatis的全局配置文件 --> <property name="configLocation" value="classpath:mybatis/sqlMapConfig.xml" /> </bean> <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <property name="basePackage" value="com.hdu.dao" /><!-- 具体dao层包的位置在哪，视你新建的dao层java包而定 --> </bean> </beans>
8、applicationContext-service.xml
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:context="http://www.springframework.org/schema/context" xmlns:p="http://www.springframework.org/schema/p" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-4.0.xsd"> <!-- 包扫描器 --> <context:component-scan base-package="com.hdu.service"/><!-- 具体service包的路径取决于你新建的java代码的service层包 --> </beans>
9、applicationContext-tx.xml(事务)
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:context="http://www.springframework.org/schema/context" xmlns:p="http://www.springframework.org/schema/p" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-4.0.xsd"> <import resource="applicationContext-dao.xml"></import> <!-- 事务管理器 --> <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <!-- 数据源 --> <property name="dataSource" ref="dataSource" /> </bean> <!-- 通知 --> <tx:advice id="txAdvice" transaction-manager="transactionManager"> <tx:attributes> <!-- 传播行为 --> <tx:method name="save*" propagation="REQUIRED" /> <tx:method name="insert*" propagation="REQUIRED" /> <tx:method name="add*" propagation="REQUIRED" /> <tx:method name="create*" propagation="REQUIRED" /> <tx:method name="delete*" propagation="REQUIRED" /> <tx:method name="update*" propagation="REQUIRED" /> <tx:method name="find*" propagation="SUPPORTS" read-only="true" /> <tx:method name="select*" propagation="SUPPORTS" read-only="true" /> <tx:method name="get*" propagation="SUPPORTS" read-only="true" /> </tx:attributes> </tx:advice> <!-- 切面 --> <aop:config> <aop:advisor advice-ref="txAdvice" pointcut="execution(* com.hdu.service.*.*(..))" /> </aop:config> </beans>
10、spring-mvc.xml
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p" xmlns:context="http://www.springframework.org/schema/context" xmlns:mvc="http://www.springframework.org/schema/mvc" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd"> <!-- 配置包扫描器 --> <context:component-scan base-package="com.hdu.controller"/> <!-- 具体controller包的路径取决于你新建的java代码的controller层包 --> <!-- 配置注解驱动--> <mvc:annotation-driven/> <!--静态资源访问--> <mvc:default-servlet-handler/> <!--视图解析器--> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/WEB-INF/"/> <property name="suffix" value=".jsp"/> <property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/> </bean> <!--拦截器--> <!-- <mvc:interceptors> <!–可配置多个拦截器,顺序执行 –> <mvc:interceptor> <mvc:mapping path="/product/**"/><!–如果不配置或/*,将拦截所有的Controller –> <bean class="manage.base.interceptor.PermissionInterceptor"></bean> </mvc:interceptor> </mvc:interceptors>--> </beans>
11、UserController
package com.hdu.controller; import com.hdu.entity.User; import com.hdu.service.UserService; import org.springframework.stereotype.Controller; import org.springframework.ui.Model; import org.springframework.web.bind.annotation.RequestMapping; import javax.annotation.Resource; @Controller @RequestMapping("/show") public class UserController { @Resource private UserService userService; @RequestMapping("/showUserById") public String showUserById(Integer id,Model model){ User user = userService.findUserById(id); model.addAttribute("user",user); return "result"; } }
12、UserServiceImpl和UserService(接口略)
package com.hdu.service.impl; import com.hdu.entity.User; import com.hdu.dao.UserMapper; import com.hdu.service.UserService; import org.springframework.stereotype.Service; import javax.annotation.Resource; @Service public class UserServiceImpl implements UserService { @Resource private UserMapper userMapper; @Override public User findUserById(Integer id) { User user = userMapper.findUserById(id); return user; } }
13、UserMapper接口
package com.hdu.dao; import com.hdu.entity.User; public interface UserMapper { User findUserById(Integer id); }
14、UserMapper.xml(mybatis的文件)
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd"> <!-- 设置为IUserDao接口方法提供sql语句配置 --> <mapper namespace="com.hdu.dao.UserMapper"> <select id="findUserById" resultType="com.hdu.entity.User" parameterType="int"> SELECT * FROM user WHERE id = #{id} </select> </mapper>
15、entity类User
package com.hdu.entity; public class User { private Integer id; private String email; private String password; private String username; private String role; private int status; private String regIp; public Integer getId() { return id; } public void setId(Integer id) { this.id = id; } public String getEmail() { return email; } public void setEmail(String email) { this.email = email; } public String getPassword() { return password; } public void setPassword(String password) { this.password = password; } public String getUsername() { return username; } public void setUsername(String username) { this.username = username; } public String getRole() { return role; } public void setRole(String role) { this.role = role; } public int getStatus() { return status; } public void setStatus(int status) { this.status = status; } public String getRegIp() { return regIp; } public void setRegIp(String regIp) { this.regIp = regIp; } }
16、user.sql数据库
CREATE TABLE `user` ( `id` int(11) NOT NULL AUTO_INCREMENT COMMENT ‘用户ID‘, `email` varchar(255) NOT NULL COMMENT ‘用户邮箱‘, `password` varchar(255) NOT NULL COMMENT ‘用户密码‘, `username` varchar(255) NOT NULL COMMENT ‘用户昵称‘, `role` varchar(255) NOT NULL COMMENT ‘用户身份‘, `status` int(1) NOT NULL COMMENT ‘用户状态‘, `regTime` datetime NOT NULL COMMENT ‘注册时间‘, `regIp` varchar(255) NOT NULL COMMENT ‘注册IP‘, PRIMARY KEY (`id`), UNIQUE KEY `email` (`email`) USING BTREE ) ENGINE=InnoDB AUTO_INCREMENT=2 DEFAULT CHARSET=utf8;
17、咳咳，项目的主页index.jsp
<html>
<h2>Hello World!</h2>
<hr size="12" color="blue"/>
<form action="${pageContext.request.contextPath}/show/showUserById.do">
id:<input type="text" name="id" id="id">
<input type="submit" value="提交">
</form>
</body>
</html>
18、result.jsp
<%-- Created by IntelliJ IDEA. User: YanZH Date: 2018/6/22 Time: 16:28 To change this template use File | Settings | File Templates. --%> <%@ page contentType="text/html;charset=UTF-8" language="java" %> <html> <head> <title>Title</title> </head> <body> 嘿嘿，看看这是啥 ${user } </body> </html>
19、项目配置Tomcat一通跑，OVER
