使用IntelliJ IDEA搭建SSM框架的图文教程

1.使用IDEA新建项目

2.选择创建Maven工程

3.填写GroupId和ArtifactId

4.填写项目名称，与上一步的ArtifactId一致即可，然后点Finish

5.刚建好的目录只是一个Maven的目录结构，如下

6.完善目录结构，添加webapp、WEB-INF目录，以及web.xml文件

7.修改IDEA的Maven设置，Maven默认的本地仓库会保存在C盘，为了方便以后使用，尽量修改本地仓库的位置，因为这是框架整合，所以具体的修改方式在这里不多做说明。快捷键ctrl+alt+s，在搜索框中搜索Maven，如下

9.修改Maven的核心配置文件pom.xml，添加框架所需要的依赖

10.在resources目录下添加配置文件

文件目录如下

a)连接数据库配置信息文件-db.properties

druid.driver=com.mysql.jdbc.Driver
druid.url=jdbc:mysql://localhost:3306/all_db?characterEncoding=utf-8
druid.username=root
druid.password=root

 b)Mybatis核心配置文件-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>
<!-- 给实体类起别名 -->
<typeAliases >
 <package name="com.xiao.pojo"/>
</typeAliases>
</configuration>

c)Spring核心配置文件，整合Mybatis，applicationContext.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xmlns="http://www.springframework.org/schema/beans"
 xmlns:context="http://www.springframework.org/schema/context"
 xmlns:tx="http://www.springframework.org/schema/tx"
 xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.2.xsd
     http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.2.xsd
     http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.2.xsd">
<!-- 加载数据库连接信息配置文件 -->
<context:property-placeholder location="classpath:db.properties" />
<!--druid连接池 -->
<bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource">
 <property name="driverClassName" value="${druid.driver}" />
 <property name="url"   value="${druid.url}" />
 <property name="username"   value="${druid.username}" />
 <property name="password"   value="${druid.password}" />
</bean>
<!-- 配置Mybatis工厂 -->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
 <property name="dataSource" ref="dataSource" />
 <property name="configLocation" value="classpath:SqlMapConfig.xml" />
</bean>
<!-- Mapper * 开发 扫包 给定包下的接口文件名和映射文件名必须相同 创建接口的实现类-->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
 <property name="basePackage" value="com.xiao.mapper" />
</bean>
<!-- 开启事物 -->
<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
 <property name="dataSource" ref="dataSource" />
</bean>
<!-- 事物注解驱动-->
<tx:annotation-driven />
</beans>

 d)SpringMVC配置文件-springmvc.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xmlns="http://www.springframework.org/schema/beans"
 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-4.2.xsd
     http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.2.xsd
     http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.2.xsd">
<!-- 配置扫描注解 @Controller @Service -->
<context:component-scan base-package="com.xiao" />
<!-- SpringMVC使用<mvc:annotation-driven>自动加载RequestMappingHandlerMapping和RequestMappingHandlerAdapter -->
<mvc:annotation-driven />
<!-- 配置静态资源映射 -->
<!--
<mvc:resources location="/js/" mapping="/js/**"/>
<mvc:resources location="/css/" mapping="/css/**"/>
<mvc:resources location="/imgs/" mapping="/imgs/**"/>
<mvc:resources location="/font/" mapping="/font/**"/>
-->
<!-- 配置视图解析器-->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
 <!-- 配置逻辑视图的前缀 -->
 <property name="prefix" value="/WEB-INF/jsp/" />
 <!-- 配置逻辑视图的后缀 -->
 <property name="suffix" value=".jsp" />
</bean>
</beans>

11.配置web.xml文件

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/javaee"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
  http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
  version="2.5">
<display-name>SSM</display-name>
<welcome-file-list>
 <welcome-file>index.jsp</welcome-file>
</welcome-file-list>
<!-- spring * -->
<listener>
 <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<!-- 指定spring核心配置文件 -->
<context-param>
 <param-name>contextConfigLocation</param-name>
 <param-value>classpath:applicationContext.xml</param-value>
</context-param>
<!-- 处理POST提交乱码问题 -->
<filter>
 <filter-name>encoding</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>encoding</filter-name>
 <url-pattern>/*</url-pattern>
</filter-mapping>
<!-- 配置前端控制器 -->
<servlet>
 <servlet-name>springmvc</servlet-name>
 <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
 <!-- 指定配置文件位置和名称 如果不设置,默认找/WEB-INF/<servlet-name>-servlet.xml -->
 <init-param>
  <param-name>contextConfigLocation</param-name>
  <param-value>classpath:springmvc.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>
</web-app>

12.完善目录结构，书写实体类、web层、service层、dao层以及测试页面，目录结构如下

13.配置tomcat

14.启动Tomcat，访问地址： http://localhost:8080/getAll   进行测试，结果如下

出现以上结果，表示SSM框架搭建成功！

数据库数据如下

在jsp页面用EL表达式取值

总结

以上所述是小编给大家介绍的使用IntelliJ IDEA搭建SSM框架的图文教程网站的支持！
