第一步：创建maven项目并完善项目结构
第二步：相关配置
pom.xml
引入相关jar包

114 配置编译java路径下的xml文件（当mybatis采用mapper.xml形式编写sql语句的时候，放在dao层下的xml文件maven默认是不编译的）
115 在build标签里加入以下代码
116
117 <resources>
118 <!--编译src/main/java目录下的xml文件-->
119 <resource>
120 <directory>src/main/java</directory>
121 <includes>
122 <include>**/*.xml</include>
123 </includes>
124 <filtering>true</filtering>
125 </resource>
126 </resources>
到此为止pom.xml就配置好了
-----------------------------------------------------------------------------------------------------------------------------------------
接下来我们配置mybatis的配置文件
SqlMapConfig.xml（因为我们后面要整合Spring所以很多配置都放在了Spring配置文件里面 这里我们只配置一下别名方便以后mapper.xml的编写）
<?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>
<!--配置别名-->
<typeAliases>
<!--domain包路径>
<package name="cn.jydm.domain"></package>
</typeAliases>
</configuration>
jdbc.properties（这里主要填写一下数据库的相关数据 我只填写了必要的数据 链接限制等自己根据情况填写)
driverClass=com.mysql.jdbc.Driver
url=jdbc:mysql://localhost:3306/数据库名?useUnicode=true&characterEncoding=utf8
user=root （这里说明一下之所以没有填username 是因为在Spring配置文件里面编写${username} 会获取到主机名字 导致连接数据库失败）
password=密码
到这数据库的相关东西都编写好了
-------------------------------------------------------------------------------------------------------------------------------------------
SpringMVC的配置
springmvc.xml
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation=" http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context.xsd">
<!-- 配置spring创建容器时要扫描的包 -->
<context:component-scan base-package="cn.jydm.contraller" />
<!-- 配置视图解析器 -->
<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/pages/"></property>
<property name="suffix" value=".jsp"></property>
</bean>
<!-- 配置spring开启注解mvc的支持-->
<mvc:annotation-driven></mvc:annotation-driven>
</beans>
---------------------------------------------------------------------------------------------------------------------------------------
接下来我们配置一下spring的配置文件（因为无论是SpringMVC还是Mybatis都是与Spring整合所以我们最后配置Spring）
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/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">
<!--引入jdbc配置文件-->
<context:property-placeholder location="classpath:jdbc.properties"></context:property-placeholder>
<!--开启注解的扫描，希望处理service和dao，controller不需要Spring框架去处理-->
<context:component-scan base-package="cn.jydm" >
<!--配置哪些注解不扫描-->
<context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller" />
</context:component-scan>
<!--spring整合mybatis框架-->
<!-- 配置Durid的连接池对象 -->
<bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource" init-method="init"
destroy-method="close">
<property name="driverClassName" value="${driverClass}" />
<property name="url" value="${url}" />
<property name="username" value="${user}" />
<property name="password" value="${password}" />
</bean>
<!-- 配置SqlSession的工厂 -->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource" />
<!--指定mapper的配置文件-->
<property name="configLocation" value="classpath:SqlMapConfig.xml" />
<!--指定mapper文件的存放路径-->
<property name="mapperLocations" value="classpath:cn/jydm/dao/*.xml"/>
</bean>
<!-- 配置扫描dao的包 -->
<bean id="mapperScanner" class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="cn.jydm.dao"/>
<property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/>
</bean>
</beans>
这样所有的配置文件就都写好了SSM框架也就整合完毕了
最后还有一个日志文件
log4j.properties
# Global logging 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
在整合过程中出现了tomcat启动失败的问题，后来发现是配置别名的时候包路径没有写对 导致mapper.xml里的返回值类型出现了找不到的问题。
