Spring SpringMvc Mybatis 整合即SSM整合
前言
整合SSM是学习Spring、SpringMvc和Mybatis更加深层的理解,本篇也仅列举常用配置,仅供初学者配置和自己日后查阅。本篇采用idea开发结合maven使得项目配置更加简单。
本文默认读者会maven项目创建,已省略idea中maven创建流程,若需要后续出教程
1. maven中pom.xml文件配置
<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

2. Spring配置文件applicationContext.xml配置(ps:建议命名为applicationContext.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: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/aop http://www.springframework.org/schema/aop/spring-aop-4.3.xsd
http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.3.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">
<!-- 加载外部文件 这里加载的是数据库配置文件-->
<context:property-placeholder location="classpath:dbconfig.properties"/>
<!-- 开启IOC扫描 这里是根据自身项目扫描,仅扫描service包下 -->
<context:component-scan base-package="com.ssm.service"/>
<!-- 配置 C3P0 数据源 -->
<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource" >
<property name="user" value="${jdbc.user}"/>
<property name="password" value="${jdbc.password}"/>
<property name="driverClass" value="${jdbc.driverClass}"/>
<property name="jdbcUrl" value="${jdbc.jdbcUrl}"/>
<property name="initialPoolSize" value="${jdbc.initialSize}"/>
<property name="maxPoolSize" value="10"/>
</bean>
<!-- 配置MyBatis SqlSessionFactory -->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<!-- 指定MyBatis 数据源 -->
<property name="dataSource" ref="dataSource"/>
<!-- 指定MyBatis mapper文件的位置 -->
<property name="mapperLocations" value="classpath:com/ssm/mapper/*.xml"/>
<!-- 指定MyBatis全局配置文件的位置 -->
<property name="configLocation" value="classpath:mybatis-config.xml"/>
</bean>
<!--扫描MyBatis的mapper接口 -->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<!--扫描所有dao接口的实现,加入到ioc容器中 -->
<property name="basePackage" value="cn.xyes.mapper"/>
</bean>
<!-- 开启Spring事务 -->
<bean id="txManager"
class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource" />
</bean>
<!-- 开启事务注解 -->
<tx:annotation-driven transaction-manager="txManager" />
</beans>
3.SpringMVC配置文件springmvc.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: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/context http://www.springframework.org/schema/context/spring-context.xsd
http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd">
<!-- 告知spring,启用springmvc的注解驱动 annotation: 注解-->
<mvc:annotation-driven />
<!--component : 组件-->
<!-- 扫描Controller包下类 -->
<context:component-scan
base-package="com.ssm.controller">
</context:component-scan>
<!-- 注解驱动 -->
<mvc:annotation-driven/>
<!-- 配置视图解析器 -->
<bean id="viewResolver"
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/"/>
<property name="suffix" value=".html"/>
</bean>
<mvc:view-controller path="/" />
<mvc:default-servlet-handler/>
</beans>
3.Mybatis配置文件,这里大部分已经配置到spring的配置文件中,因此配置内容比较少
<?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>
<!-- 打印SQL-->
<setting name="logImpl" value="STDOUT_LOGGING" />
</settings>
<typeAliases>
<!-- 指定一个包名,MyBatis会在包名下搜索需要的JavaBean(即dao层包)-->
<package name="com.ssm.mapper"/>
</typeAliases>
</configuration>
4.数据库配置文件dbconfig.properties配置
jdbc.jdbcUrl=jdbc:mysql://localhost:3306/demo?useUnicode=true&characterEncoding=UTF-8
jdbc.driverClass=com.mysql.jdbc.Driver
jdbc.user=root
jdbc.password=123456
jdbc.maxTotal=30
jdbc.maxIdle=20
jdbc.initialSize=5
5.web.xml配置
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.4"
xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">
<!-- 加载Spring -->
<context-param>
<param-name>
contextConfigLocation
</param-name>
<param-value>
classpath:applicationContext.xml
</param-value>
</context-param>
<!-- Listener监听 -->
<listener>
<listener-class>
org.springframework.web.context.ContextLoaderListener
</listener-class>
</listener>
<!-- 加载静态资源 -->
<servlet-mapping>
<servlet-name>default</servlet-name>
<url-pattern>*.js</url-pattern>
</servlet-mapping>
<servlet-mapping>
<servlet-name>default</servlet-name>
<url-pattern>*.css</url-pattern>

</servlet-mapping>
<!--springmvc前端核心控制器-->
<servlet>
<servlet-name>springmvc</servlet-name>
<servlet-class>
org.springframework.web.servlet.DispatcherServlet
</servlet-class>
<!-- 初始化加载配置文件-->
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:springmvc.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<!-- 字符编码过滤器,一定要放在所有过滤器之前 -->
<!-- 字符编码过滤器 -->
<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>

总结
本篇SSM整合配置目的是能让学过但未整合过的同学复制粘贴后即可食用,因为博主刚开始整合是也走过不少弯路,配置文件东凑西凑就是跑不起来,所以记录一下,实际中ssm使用并不多(现在大多使用springboot)ssm仅为初学者必经学习的项目,博主也有整合redis和jwt配置文件,和一些整合遇到的坑,如果需要帮助可以留言或者私信我。因水平有限若有不合理指出请评论指出,谢谢。
