整合思路：因为spring和spring mvc同源，可以无缝整合，故先整合spring+mybatis，然后配置web.xml、spring mvc、log4j等相关配置文件
步骤1：myeclipse创建项目，导入spring框架
右击项目名 —— Configure Facets —— Install Spring Facet
一路Next到Configuer Project Libraries后，勾选Spring Persistence,然后Finsh
Finsh后会自动在src下创建applicationContext.xml文件，该文件为spring框架的配置文件
步骤2：开始整合Spring+Mybatis
首先导入整合所需要的jar包：mybatis-3.4.6.jar、mybatis-spring-1.3.1.jar、mysql-connector-java-5.1.20-bin.jar（版本自行选择），并建立Source Folder文件夹命名为resource，用以存放相关的配置源文件
建立好Source Folder文件夹后，把spring的配置文件applicationContext拖到此文件夹中，进行统一管理
1.建立数据源配置文件
建立file文件，并命名为database.properties,建立完成后，双击进入选择Source开始编写数据库的相关配置属性
注意：相关参数要根据自己的情况进行更改
database.propertidriver=com.mysql.jdbc.Driver
url=jdbc:mysql://localhost:3306/your database username=root password=your passwrod
2.在applicationContext.xml中进行spring+mybatis的整合：
同样，配置信息里的相关包名也要根据自己的情况进行更改，下同
<?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:context="http://www.springframework.org/schema/context" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:jdbc="http://www.springframework.org/schema/jdbc" xsi:schemaLocation="http://www.springframework.org/schema/jdbc http://www.springframework.org/schema/jdbc/spring-jdbc-4.1.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.1.xsd http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.1.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.1.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.1.xsd">
<!-- 读取数据库配置文件 -->
<context:property-placeholder location="classpath:database.propertise"/>
<!-- 获取数据源(使用dbcp连接池) -->
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close" scope="singleton">
<property name="driverClassName" value="${driver}" />
<property name="url" value="${url}" />
<property name="username" value="${username}" />
<property name="password" value="${password} " />
</bean>
<!-- 配置Mybatis的SqlSessionFactoryBean -->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<!-- 引用数据源组件 -->
<property name="dataSource" ref="dataSource" />
<!-- 引用MyBatis配置文件中的配置 -->
<property name="configLocation" value="classpath:mybatis-config.xml" />
</bean>
<!-- 配置MyBatis的MapperScannerConfigurer,自动生成Mapper的对象 -->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="cn.xin.dao" />
</bean>
<!-- 配置service,扫描注解定义的业务Bean -->
<context:component-scan base-package="cn.xin.service" />
</beans>
步骤3：进行Spring MVC和一些相关文件的配置
1.在web.xml中配置DispatcherServlet和字符编码过滤器：
<?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" version="3.0">
<display-name>Test_SSM</display-name>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext.xml</param-value>
</context-param>
<!-- springmvc拦截请求 -->
<servlet>
<servlet-name>springmvc</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:springmvc-servlet.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>
<!-- 配置编码过滤器 -->
<filter>
<filter-name>CharacterEncoding</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>CharacterEncoding</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
</web-app>
2.在resource文件夹下建立springmvc-servlet.xml,并配置相关信息：
<?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/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.1.xsd 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-4.1.xsd">
<!-- 扫描带注解的包 -->
<context:component-scan base-package="cn.xin.controller" />
<!-- 引入静态资源 -->
<mvc:annotation-driven />
<mvc:default-servlet-handler />
<!-- 配置视图解析器 -->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/views/"></property>
<property name="suffix" value=".jsp"></property>
</bean>
3.在resource文件夹下，建立mybatis-config.xml并配置相关信息:
<?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>
<typeAliases>
<package name="cn.xin.pojo" />
</typeAliases>
</configuration>
4.建立并编写log4j.propertise文件：
# Global loggin configuration log4j.rootLogger=DEBUG,stdout # Console output... log4j.appender.stdout=org.apache.log4j.ConsoleAppender log4j.appender.stdout.layout=org.apache.log4j.PatternLayout log4j.appender.stdout.layout.ConversionPattern=%5p [%t] - %m%n
至此，SSM框架的整合已经基本完成，下面进行编写测试代码
步骤4：进行SSM整合的测试
测试思路：jsp+a标签携带参数 ——> controller ——> service ——> dao ——> 数据库 ——> jsp显示查询结果
