一、基于Idea集成环境Maven管理的Web项目创建
1、新建一个project
2、补充好项目结构（这里其实可以通过配置来补充，生成之后就是完整的项目目录结构），这里要是自己创建完之后，要是文件不像这种样式的，需要自己改一下文件类型
注意一定要配置好webapp路径
3、配置Tomcat
完成以上步骤基本的Maven管理的Web项目就搭建完成了。
二、配置pom.xml
配置文件信息：
1 <?xml version="1.0" encoding="UTF-8"?> 2 3 <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 4

三、配置SSM框架配置文件
1、mybatis-config.xml
1 <?xml version="1.0" encoding="UTF-8" ?> 2 <!DOCTYPE configuration 3 PUBLIC "-//mybatis.org//DTD Config 3.0//EN" 4 "http://mybatis.org/dtd/mybatis-3-config.dtd"> 5 <configuration> 6 <!--打印日志--> 7 <settings> 8 <setting name="logImpl" value="STDOUT_LOGGING"/> 9 </settings> 10 <!--resultType启别名--> 11 <typeAliases> 12 <package name="com.crm.model"/> 13 </typeAliases> 14 <!--指向mapper文件位置--> 15 <mappers> 16 <package name="com.crm.mapper"/> 17 </mappers> 18 </configuration>
2、applicationContext-mvc.xml
1 <?xml version="1.0" encoding="UTF-8"?> 2 <beans xmlns="http://www.springframework.org/schema/beans" 3 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 4 xmlns:context="http://www.springframework.org/schema/context" 5 xmlns:p="http://www.springframework.org/schema/p" 6 xmlns:util="http://www.springframework.org/schema/util" 7 xmlns:aop="http://www.springframework.org/schema/aop" 8 xmlns:tx="http://www.springframework.org/schema/tx" 9 xmlns:mvc="http://www.springframework.org/schema/mvc" 10 xsi:schemaLocation=" 11 http://www.springframework.org/schema/beans 12 http://www.springframework.org/schema/beans/spring-beans.xsd 13 http://www.springframework.org/schema/context 14 http://www.springframework.org/schema/context/spring-context.xsd 15 http://www.springframework.org/schema/tx 16 http://www.springframework.org/schema/tx/spring-tx.xsd 17 http://www.springframework.org/schema/aop 18 http://www.springframework.org/schema/aop/spring-aop.xsd 19 http://www.springframework.org/schema/mvc 20 http://www.springframework.org/schema/mvc/spring-mvc.xsd 21 http://www.springframework.org/schema/util 22 http://www.springframework.org/schema/util/spring-util.xsd"> 23 <!-- dispatcherServlet截获所有URL请求 --> 24 <mvc:default-servlet-handler /> 25 <!-- spring mvc 扫描包下的controller --> 26 <context:component-scan base-package="com.crm.controller"/> 27 <!-- <context:component-scan base-package="com.crm.crm.settings.web.controller"/> 28 <context:component-scan base-package="com.crm.crm.workbench.web.controller"/>--> 29 <!-- 配置注解驱动 --> 30 <mvc:annotation-driven/> 31 <!-- 配置视图解析器 --> 32 <bean id="viewResolver" 33 class="org.springframework.web.servlet.view.InternalResourceViewResolver"> 34 <property name="prefix" value="/WEB-INF/pages/"/> 35 <property name="suffix" value=".jsp"/> 36 </bean> 37 <!-- 配置文件上传解析器 id:必须是multipartResolver--> 38 <!--<bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver"> 39 <property name="maxUploadSize" value="#{1024*1024*80}"/> 40 <property name="defaultEncoding" value="utf-8"/> 41 </bean>--> 42 </beans>
3、applicationContext-datasource.xml
1 <?xml version="1.0" encoding="UTF-8"?> 2 <beans xmlns="http://www.springframework.org/schema/beans" 3 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 4 xmlns:aop="http://www.springframework.org/schema/aop" 5 xmlns:context="http://www.springframework.org/schema/context" 6 xmlns:tx="http://www.springframework.org/schema/tx" 7 xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd 8 http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.3.xsd 9 http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.3.xsd 10 http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.3.xsd"> 11 <!--这个文件是spring整合mybatis--> 12 <!-- 配置数据源 ，因为我们要让spring去管理数据库的事务，所以要让spring知道连接信息，这个数据源作用就是这个--> 13 <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource"> 14 <property name="driverClassName" value="com.mysql.cj.jdbc.Driver"/> 15 <property name="username" value="root"/> 16 <property name="password" value="22222"/> 17 <property name="url" value="jdbc:mysql://127.0.0.1:3306/crmssm?useSSL=false&useUnicode=true&characterEncoding=UTF-8&serverTimezone=Asia/Shanghai"/> 18 </bean> 19 20 <!-- 配置SqlSessionFactory，相当于是一个数据库的实例，这样spring就实现了对数据库的管理 --> 21 <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> 22 <!-- 必须注入属性dataSource --> 23 <property name="dataSource" ref="dataSource"/> 24 <!-- 如果mybatis没有特殊的配置(比如别名等)，configLocation可以省去 ;否则，不能省略--> 25 <property name="configLocation" value="classpath:mybatis-config.xml"/> 26 </bean> 27 28 29 <!-- mapper注解扫描器配置,扫描@MapperScan注解,通过动态代理机制，自动生成实现类对象 --> 30 <bean id="mapperScanner" class="org.mybatis.spring.mapper.MapperScannerConfigurer"> 31 <property name="basePackage" value="com.crm.mapper"/> 32 <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/> 33 </bean> 34 35 <!-- 配置事务管理器 --> 36 <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> 37 <property name="dataSource" ref="dataSource"/> 38 </bean> 39 40 <!-- 配置事务 --> 41 <aop:config> 42 <aop:pointcut expression="execution(* com.crm.service.*.*(..))" id="allMethodPointcut"/> 43 <aop:advisor advice-ref="txAdvice" pointcut-ref="allMethodPointcut"/> 44 </aop:config> 45 <tx:advice id="txAdvice" transaction-manager="transactionManager"> 46 <tx:attributes> 47 <tx:method name="add*" propagation="REQUIRED" rollback-for="Exception"/> 48 <tx:method name="save*" propagation="REQUIRED" rollback-for="Exception"/> 49 <tx:method name="edit*" propagation="REQUIRED" rollback-for="Exception"/> 50 <tx:method name="update*" propagation="REQUIRED" rollback-for="Exception"/> 51 <tx:method name="delete*" propagation="REQUIRED" rollback-for="Exception"/> 52 <tx:method name="do*" propagation="REQUIRED" rollback-for="Exception"/> 53 <tx:method name="*" propagation="REQUIRED" read-only="true"/> 54 </tx:attributes> 55 </tx:advice> 56 </beans>
4、applicationContext.xml
1 <?xml version="1.0" encoding="UTF-8"?> 2 <beans xmlns="http://www.springframework.org/schema/beans" 3 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 4 xmlns:context="http://www.springframework.org/schema/context" 5 xmlns:p="http://www.springframework.org/schema/p" 6 xmlns:aop="http://www.springframework.org/schema/aop" 7 xmlns:tx="http://www.springframework.org/schema/tx" 8 xmlns:task="http://www.springframework.org/schema/task" 9 xsi:schemaLocation=" 10 http://www.springframework.org/schema/beans 11 http://www.springframework.org/schema/beans/spring-beans.xsd 12 http://www.springframework.org/schema/context 13 http://www.springframework.org/schema/context/spring-context.xsd 14 http://www.springframework.org/schema/tx 15 http://www.springframework.org/schema/tx/spring-tx.xsd 16 http://www.springframework.org/schema/aop 17 http://www.springframework.org/schema/aop/spring-aop.xsd"> 18 <!-- 加载系统配置文件 19 <context:property-placeholder location="classpath:*.properties" />--> 20 <!-- 扫描注解，这里只对service进行扫描，因为mapper和controller在别的配置文件中已经扫描了 --> 21 <context:component-scan base-package="com.crm.service" /> 22 <!-- 导入数据相关配置 --> 23 <import resource="applicationContext-datasource.xml" /> 24 </beans>
四、Web.xml配置文件
1 <?xml version="1.0" encoding="UTF-8"?> 2 <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 3 xmlns="http://java.sun.com/xml/ns/javaee" 4 xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 5 http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" 6 id="dataservice" version="3.0"> 7 <display-name>dataservice application</display-name> 8 9 <!-- spring监听器加载applicationContext.xml配置文件 --> 10 <context-param> 11 <param-name>contextConfigLocation</param-name> 12 <param-value>classpath:applicationContext.xml</param-value> 13 </context-param> 14 <listener> 15 <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> 16 </listener> 17 18 <!-- spring字符过滤器 --> 19 <filter> 20 <filter-name>encodingFilter</filter-name> 21 <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> 22 <init-param> 23 <param-name>encoding</param-name> 24 <param-value>UTF-8</param-value> 25 </init-param> 26 </filter> 27 <filter-mapping> 28 <filter-name>encodingFilter</filter-name> 29 <url-pattern>/*</url-pattern> 30 </filter-mapping> 31 32 <!-- Spring mvc分发servlet --> 33 <servlet> 34 <servlet-name>dispatcher</servlet-name> 35 <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> 36 <init-param> 37 <param-name>contextConfigLocation</param-name> 38 <param-value>classpath:applicationContext-mvc.xml</param-value> 39 </init-param> 40 <load-on-startup>1</load-on-startup> 41 </servlet> 42 43 <servlet-mapping> 44 <servlet-name>dispatcher</servlet-name> 45 <url-pattern>/</url-pattern> 46 </servlet-mapping> 47 48 <!-- 欢迎页，默认进入index controller --> 49 <welcome-file-list> 50 <welcome-file>/</welcome-file> 51 </welcome-file-list> 52 </web-app>
完成上面步骤，那么配置就完成了，现在就可以创建对应的包，开始编写代码了。
