这只是讲解如何整合SSM，前提是已经创建好maven工程，可以下载整合完整的Demo,修改数据库连接应该可以运行成功
这里也有单独的pom.xml
这里写图片描述

一、创建maven工程

二、在pom.xml中加载jar包

<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 http://maven.apache.org/maven-v4_0_0.xsd">
  <modelVersion>4.0.0</modelVersion>
  <groupId>com.cn</groupId>
  <artifactId>OAProject</artifactId>
  <packaging>war</packaging>
  <version>0.0.1-SNAPSHOT</version>
  <name>OAProject Maven Webapp</name>
  <url>http://maven.apache.org</url>
   <properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
  </properties>
  <dependencies>
    <dependency>
      <groupId>junit</groupId>
      <artifactId>junit</artifactId>
      <version>3.8.1</version>
      <scope>test</scope>
    </dependency>

    <dependency>
      <groupId>javax</groupId>
      <artifactId>javaee-api</artifactId>
      <version>7.0</version>

    </dependency>

    <dependency>

    </dependency>

    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-jdbc</artifactId>

    </dependency>

    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-aspects</artifactId>
        <version>4.3.3.RELEASE</version>
    </dependency>

    <dependency>
        <groupId>org.mybatis</groupId>
        <artifactId>mybatis-spring</artifactId>
        <version>1.3.0</version>
    </dependency>

    <dependency>
        <groupId>org.mybatis</groupId>

    </dependency>

    <dependency>
        <groupId>commons-dbcp</groupId>
        <artifactId>commons-dbcp</artifactId>
        <version>1.2.2</version>
    </dependency>

    <dependency>
        <groupId>javax.servlet</groupId>
        <artifactId>javax.servlet-api</artifactId>
        <version>4.0.0</version>
    </dependency>

    <dependency>

    </dependency>

  </dependencies>
  <build>
    <finalName>OAProject</finalName>
  </build>
</project>

三、创建jdbc.properties

driver=com.mysql.jdbc.Driver
url=jdbc:mysql://localhost:3306/userdata?characterEncoding=utf-8
username=root
password=111

四、创建mybatis.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>     
        <!-- 允许JDBC支持生成的键 -->
        <setting name="useGeneratedKeys" value="true"/> 
    </settings>  
    <typeAliases>
        <!-- 配置数据类型的别名 -->
        <typeAlias type="com.cn.pojo.User"  alias="user"/>

    </typeAliases>
</configuration>

五.配置web.xml文件

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.0" 
    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_3_0.xsd">
  <display-name></display-name> 
  <welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
  </welcome-file-list>

  <!-- 启动监听器 -->
  <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>

  <!--读取spring配置文件 -->
  <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:springMVC-servlet.xml</param-value>
  </context-param>

  <!-- 配置springMVC核心-->
  <servlet>
    <servlet-name>SpringMVC</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <!-- 指定sprinMVC路径 -->
    <init-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:springMVC-servlet.xml</param-value>
    </init-param>
  </servlet>

  <servlet-mapping>
    <servlet-name>SpringMVC</servlet-name>
    <url-pattern>*.form</url-pattern>
  </servlet-mapping>

  <!--设置编码格式-->
  <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>
        <init-param>
            <param-name>forceEncoding</param-name>
            <param-value>true</param-value>
        </init-param>
  </filter>
  <filter-mapping>
    <filter-name>characterEncodingFilter</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>

</web-app>

六.配置springMVC文件

<?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:mvc="http://www.springframework.org/schema/mvc"
    xmlns:tx="http://www.springframework.org/schema/tx"
    xmlns:context="http://www.springframework.org/schema/context"
    xsi:schemaLocation="http://www.springframework.org/schema/beans 
                        http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
                        http://www.springframework.org/schema/mvc 
                        http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd
                        http://www.springframework.org/schema/context
                        http://www.springframework.org/schema/context/spring-context-3.0.xsd
                        http://www.springframework.org/schema/tx
                        http://www.springframework.org/schema/tx/spring-tx-3.0.xsd">
<!-- 扫描控制器 -->
<context:component-scan base-package="com.cn.action,com.cn.service"></context:component-scan>

<!-- 启动注解驱动 -->
<mvc:annotation-driven/>
<mvc:default-servlet-handler/>
<!-- 注入校验bean -->
<!-- <bean class="org.springframework.validation.beanvalidation.LocalValidatorFactoryBean"></bean> -->

<!-- 引入外部文件 -->
<context:property-placeholder location="classpath:jdbc.properties"/>

<!-- 连接数据源 -->
<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
    <property name="driverClassName" value="${driver}"></property>
    <property name="url" value="${url}"></property>
    <property name="username" value="${username}"></property>
    <property name="password" value="${password}"></property> 
</bean>


<!-- 将mybatis交给spring管理(spring和MyBatis完美整合，不需要mybatis的配置映射文件) -->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
    <property name="dataSource" ref="dataSource"></property>
    <property name="configLocation" value="classpath:mybatis-config.xml"></property>
    <!-- 自动扫描mapping.xml文件 -->
    <property name="mapperLocations" value="classpath:mapper/*.xml"></property>
</bean>

<!-- 扫描mapper-->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
    <property name="basePackage" value="com.cn.dao"></property>
    <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property>

</bean>



<!-- 事务管理 transaction manager, use JtaTransactionManager for global tx-->
<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
    <property name="dataSource" ref="dataSource"></property>
</bean>
<tx:annotation-driven transaction-manager="transactionManager"/>
</beans>
