idea搭建SSM的maven项目（tomcat容器）
一.创建maven的web项目
（1）选择项目的骨架
（2）写项目的坐标
（3）maven的设置
设置maven的本地仓库，以及配置文件的位置，同时点击+号，填入archetypeCatalog和internal，让maven读取本地配置即可(这样能让idea快速的创建maven的web工程)。
然后点击next
（4）创建完成
点击finish
二.添加目录并导入依赖
（一）添加java目录，main目录下创建java目录，并且将其标记为Sources Root
(2) 在main文件夹下创建resources目录，并将其标记为Resources Root
(如果有需要，可以在src目录下创建test文件夹，并创建java和resources文件夹，并将它们分别标记为Test Resources Root和Test Resources Root,这里就不创建了)
最后目录结构如下
（3）pom文件的编写（导入相关依赖）
maven.compiler.source和maven.compiler.target標簽中写jdk的版本
1 <properties> 2 <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> 3 <maven.compiler.source>1.8</maven.compiler.source> 4 <maven.compiler.target>1.8</maven.compiler.target> 5 6 <!--定义版本号 ${org.springframework.version}--> 7 <org.springframework.version>5.0.7.RELEASE</org.springframework.version> 8 <org.mybatis.version>3.4.6</org.mybatis.version> 9 10 </properties> 11 12

(4) 配置文件的编写
创建基本的文件夹，并添加文件，如图
mybatis全局配置文件的编写，创建sqlMapConfig.xml
<?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="STDOUT_LOGGING"/> </settings> <typeAliases> <!-- 批量别名定义，扫描整个包下的类，别名为类名（大小写不敏感） --> <package name="com.qfssc.domain" /> </typeAliases> <plugins> <plugin interceptor="com.github.pagehelper.PageHelper"></plugin> </plugins> </configuration>
spring整合mybatis的配置文件编写，创建application-mybatis.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:aop="http://www.springframework.org/schema/aop" 6 xmlns:tx="http://www.springframework.org/schema/tx" 7 xsi:schemaLocation="http://www.springframework.org/schema/beans 8 http://www.springframework.org/schema/beans/spring-beans.xsd 9 http://www.springframework.org/schema/context 10 http://www.springframework.org/schema/context/spring-context.xsd 11 http://www.springframework.org/schema/aop 12 http://www.springframework.org/schema/aop/spring-aop.xsd 13 http://www.springframework.org/schema/tx 14 http://www.springframework.org/schema/tx/spring-tx.xsd 15 "> 16 17 <!--spring-Mybatis整合--> 18 <!--加载数据库属性文件--> 19 <context:property-placeholder location="classpath:db.properties"/> 20 <!--连接池--> 21 <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource"> 22 <property name="driverClassName" value="${jdbc.driver}" /> 23 <!--属性文件当中的名称不能和name名称一样--> 24 <property name="url" value="${jdbc.url}" /> 25 <property name="username" value="${jdbc.username}" /> 26 <property name="password" value="${jdbc.password}" /> 27 </bean> 28 <!-- 配置事务管理器 --> 29 <bean id="transactionManager" 30 class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> 31 <!-- 数据源 --> 32 <property name="dataSource" ref="dataSource" /> 33 </bean> 34 <!-- 开启注解事务 --> 35 <tx:annotation-driven transaction-manager="transactionManager"/> 36 37 <!-- Mybatis的工厂 --> 38 <bean id="sqlSessionFactoryBean" class="org.mybatis.spring.SqlSessionFactoryBean"> 39 <property name="dataSource" ref="dataSource"/> 40 <!-- 核心配置文件的位置 --> 41 <property name="configLocation" value="classpath:sqlMapConfig.xml"/> 42 <!--配置mapper映射文件的路径--> 43 <!--<property name="mapperLocations" value="classpath:com.qfssc.mapper/*Mapper.xml"/>--> 44 </bean> 45 46 <!-- 配置Mapper接口扫描 --> 47 <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> 48 <!-- 配置Mapper扫描包 --> 49 <property name="basePackage" value="com.qfssc.mapper" /> 50 </bean> 51 52 </beans>
数据库连接的配置文件db.properties的编写
jdbc.driver=com.mysql.jdbc.Driver jdbc.url=jdbc:mysql://localhost:3306/mybatis?characterEncoding=utf-8 jdbc.username=root jdbc.password=1234
springmvc的相关配置，编写application-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:mvc="http://www.springframework.org/schema/mvc" 6 xsi:schemaLocation="http://www.springframework.org/schema/beans 7 http://www.springframework.org/schema/beans/spring-beans.xsd 8 http://www.springframework.org/schema/context 9 http://www.springframework.org/schema/context/spring-context.xsd 10 http://www.springframework.org/schema/mvc 11 http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd 12 "> 13 14 <mvc:annotation-driven /> 15 <!--静态资源处理 --> 16 <mvc:default-servlet-handler/> 17 <!--视图解析器 --> 18 <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> 19 <property name="prefix" value="/WEB-INF/views/"/> 20 <property name="suffix" value=".jsp" /> 21 </bean> 22 23 <!--配置请求拦截器,拦截所有请求,用到的时候再进行配置拦截器--> 24 <!--<mvc:interceptors> 25 <mvc:interceptor> 26 <mvc:mapping path="/*"/> 27 <bean class="com.qfssc.web.interceptor.RequestInterceptor"></bean> 28 </mvc:interceptor> 29 </mvc:interceptors>--> 30 31 </beans>
spring核心配置文件applicationContext.xml文件的编写：
<?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:context="http://www.springframework.org/schema/context" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd "> <!--注解扫描--> <context:component-scan base-package="com.qfssc"/> <!--导入mybatis--> <import resource="classpath:application-mybatis.xml"/> <!--导入springMVC--> <import resource="classpath:application-mvc.xml"/> </beans>
编写web.xml文件:
<?xml version="1.0" encoding="UTF-8"?> <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" metadata-complete="false" version="3.0"> <absolute-ordering/> <display-name>web</display-name> <welcome-file-list> <welcome-file>index.html</welcome-file> <welcome-file>index.htm</welcome-file> <welcome-file>index.jsp</welcome-file> </welcome-file-list> <!--配置前端控制器--> <servlet> <servlet-name>SpringMVC</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <!--加载spring主配置文件--> <param-value>classpath:applicationContext.xml</param-value> </init-param> <!--项目一启动就加载框架--> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>SpringMVC</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> <!--编码过滤器--> <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> </web-app>
log4j的配置文件log4j.properties编写，
1 # Global logging configuration 2 log4j.rootLogger=ERROR, stdout 3 # MyBatis logging configuration... 4 log4j.logger.com._520it.mybatis=TRACE 5 # Console output... 6 log4j.appender.stdout=org.apache.log4j.ConsoleAppender 7 log4j.appender.stdout.layout=org.apache.log4j.PatternLayout 8 log4j.appender.stdout.layout.ConversionPattern=%5p [%t] - %m%n
三.配置本地tomcat
点击Add Configuration
按部就班，然后点击ok
jre,url，和端口号一般默认就行了
依次点击
选择第二个选项，这样支持热部署，便于开发,点击ok
再点击server
再将箭头指向的位置都选成update classes and resources(支持热部署)
最后点击apply，点击ok
然后就可以看到tom猫了
点击三角形，启动tomcat.
如果以上步骤全部正确，浏览器直接打开，进入index.jsp，看到Hello World!
四.检测SpringMVC的可用性
在index.jsp中写一个表单向服务器发送请求
<%@ page contentType="text/html;charset=UTF-8" language="java" %> <html> <body> <h2>Hello World!</h2> <form action="${pageContext.request.contextPath}/student"> 姓名：<input type="text"><br> <input type="submit" value="提交"> </form> </body> </html>
编写web层，写一个StudentController，转发到success.jsp页面,只是为了测试一下，不接收参数了。。。
package com.qfssc.web; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; @Controller public class StudentController { @RequestMapping("/student") public String student(){ return "success"; } }
在views文件夹下创建success.jsp页面
<%@ page contentType="text/html;charset=UTF-8" language="java" %> <html> <head> <title>Title</title> </head> <body> <h1>success</h1> </body> </html>
在index.jsp页面里点击提交
无论是否有参数，都会跳转到success.jsp页面
说明我们springmvc生效了(mybatis自行测试，这里不做过多介绍了)
后续：使用maven的mybatis-generator插件生成代码
