ssm（spring+springmvc+mybatis）三大框架由于其良好的性能，低成本的学习，以及轻量级的特性，已经深受广大软件公司的喜爱，废话不多说，下面来介绍如何简单搭建SSM三大框架。
如果你想以普通的方式创建一个ssm框架的项目，创建好javaweb项目之后，直接在项目下面的lib文件夹下导入ssm框架的所有jar包就可以了，下面是ssm三大框架的所有jar包百度网盘下载地址：
http://pan.baidu.com/s/1i5LlDo5
这里我们的采用的是maven来搭建，如果不会创建maven项目的，请看如下的maven项目创建教程：
http://www.tpyyes.com/a/javaweb/2016/1010/21.html
以下是ssm三大框架的搭建流程：
第一步：打开eclipse，创建maven project项目，我的项目名为testDemo2，然后替换掉pom.xml文件，这个文件就是三大框架的jar包坐标位置，有了它就会自动从网络中下载jar包了，请将版本号注释上面的信息头换成你自己的。

</project>第二步：配置web.xml文件，用来启动spring配置和视图解析器。
<?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_2_5.xsd" id="MyWebApp" version="2.5"> <display-name>testDemo2</display-name> <!-- 启动spring --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring/applicationContext*.xml</param-value> </context-param> <!-- applicationContext --> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!-- 编码过滤器，以UTF8编码 --> <filter> <filter-name>encodingFilter</filter-name> <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> <init-param> <param-name>encoding</param-name> <param-value>UTF8</param-value> </init-param> </filter> <filter-mapping> <filter-name>encodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!-- 将POST请求转化为DELETE或者是PUT 要用_method指定真正的请求方法 --> <filter> <filter-name>HiddenHttpMethodFilter</filter-name> <filter-class>org.springframework.web.filter.HiddenHttpMethodFilter</filter-class> </filter> <filter-mapping> <filter-name>HiddenHttpMethodFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!-- 解决PUT请求无法提交Form的问题 --> <filter> <filter-name>HttpMethodFilter</filter-name> <filter-class>org.springframework.web.filter.HttpPutFormContentFilter</filter-class> </filter> <filter-mapping> <filter-name>HttpMethodFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!-- 加载springMVC --> <servlet> <servlet-name>testDemo2</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring/maizhe-manage-servlet.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>testDemo2</servlet-name> <url-pattern>/*</url-pattern> </servlet-mapping> /** <servlet-mapping> <servlet-name>default</servlet-name> <url-pattern>*.css</url-pattern> </servlet-mapping> <servlet-mapping> <servlet-name>default</servlet-name> <url-pattern>*.gif</url-pattern> </servlet-mapping> <servlet-mapping> <servlet-name>default</servlet-name> <url-pattern>*.jpg</url-pattern> </servlet-mapping> <servlet-mapping> <servlet-name>default</servlet-name> <url-pattern>*.png</url-pattern> </servlet-mapping> <servlet-mapping> <servlet-name>default</servlet-name> <url-pattern>*.js</url-pattern> </servlet-mapping> **/ <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> </web-app>
第三步：配置连接数据库的properties文件
jdbc.driver=com.mysql.jdbc.Driver jdbc.url=jdbc:mysql://192.168.5.11:3388/maizhe01?useUnicode=true&characterEncoding=utf8&autoReconnect=true&allowMultiQueries=true jdbc.username=root jdbc.password=1a33ee jdbc.idleConnection=60 jdbc.idleMaxAge=30 jdbc.maxConnectionNum=200 jdbc.minConnectionNum=5
第四步：配置mybatis-config.xml文件，这个文件是用来配置mybatis的。
<?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>
<!-- 引入外部资源配置文件 -->
<properties resource="jdbc.properties" />
<plugins>
<!-- 分页助手 -->
<plugin interceptor="com.github.pagehelper.PageHelper">
<property name="dialect" value="mysql" />
<!-- 设置为true时，使用RowBounds分页会进行count查询 -->
<property name="rowBoundsWithCount" value="true" />
</plugin>
<!-- 通用mapper插件 -->
<plugin interceptor="com.github.abel533.mapperhelper.MapperInterceptor">
<!--主键自增回写方法,默认值MYSQL,详细说明请看文档 -->
<property name="IDENTITY" value="mysql" />
<!--通用Mapper接口，多个通用接口用逗号隔开 -->
<property name="mappers" value="com.github.abel533.mapper.Mapper" />
</plugin>
</plugins>
<!-- 配置环境，制定数据库连接信息 -->
<environments default="development">
<environment id="development">
<transactionManager type="JDBC" />
<dataSource type="POOLED">
<property name="driver" value="${jdbc.driver}" />
<property name="url" value="${jdbc.url}" />
<property name="username" value="${jdbc.username}" />
<property name="password" value="${jdbc.password}" />
</dataSource>
</environment>
</environments>
<mappers>
</mappers>
</configuration>第五步：配置spring与mybatis整合文件，以及dao接口的包扫描，文件名为applicationContext-mybatis.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:p="http://www.springframework.org/schema/p" 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/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd"> <!-- sqlSessionFactory --> <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <!-- 配置数据源 --> <property name="dataSource" ref="dataSource"/> <!-- mybatis全局文件 --> <property name="configLocation" value="classpath:mybatis/mybatis-config.xml"/> <!-- 扫描mapper映射文件 --> <property name="mapperLocations" value="classpath:com/maizhe/mapper/*.xml"/> <!-- 配置别名包扫描 --> <property name="typeAliasesPackage" value="com.maizhe.entity"/> </bean> <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <property name="basePackage" value="com.maizhe.dao"/> </bean> </beans>
第六步：配置spring的applicationContext.xml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: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/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">
<!-- 使用spring自带的占位符替换功能 -->
<bean
class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<!-- 允许JVM参数覆盖 -->
<property name="systemPropertiesModeName" value="SYSTEM_PROPERTIES_MODE_OVERRIDE" />
<!-- 忽略没有找到的资源文件 -->
<property name="ignoreResourceNotFound" value="true" />
<!-- 配置资源文件 -->
<property name="locations">
<list>
<value>classpath:jdbc.properties</value>
</list>
</property>
</bean>
<context:component-scan base-package="com.maizhe" />
<bean id="dataSource" class="com.jolbox.bonecp.BoneCPDataSource"
destroy-method="close">
<!-- 数据库驱动 -->
<property name="driverClass" value="${jdbc.driver}" />
<!-- 相应驱动的jdbcUrl -->
<property name="jdbcUrl" value="${jdbc.url}" />
<!-- 数据库的用户名 -->
<property name="username" value="${jdbc.username}" />
<!-- 数据库的密码 -->
<property name="password" value="${jdbc.password}" />
<!-- 检查数据库连接池中空闲连接的间隔时间，单位是分，默认值：240，如果要取消则设置为0 -->
<property name="idleConnectionTestPeriod" value="${jdbc.idleConnection}" />
<!-- 连接池中未使用的链接最大存活时间，单位是分，默认值：60，如果要永远存活设置为0 -->
<property name="idleMaxAge" value="${jdbc.idleMaxAge}" />
<!-- 每个分区最大的连接数 -->
<property name="maxConnectionsPerPartition" value="${jdbc.maxConnectionNum}" />
<!-- 每个分区最小的连接数 -->
<property name="minConnectionsPerPartition" value="${jdbc.minConnectionNum}" />
</bean>
</beans>第七步：配置事务，这里是用另外一个xml文件配置的，你也可以直接把配置信息放在applicationContext.xml文件里面，文件名为applicationContext-transaction.xml。
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:context="http://www.springframework.org/schema/context" xmlns:p="http://www.springframework.org/schema/p" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" 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-4.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-4.0.xsd"> <!-- 定义事务管理器 --> <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <property name="dataSource" ref="dataSource" /> </bean> <!-- 定义事务策略 --> <tx:advice id="txAdvice" transaction-manager="transactionManager"> <tx:attributes> <!--所有以query开头的方法都是只读的 --> <tx:method name="query*" read-only="true" /> <tx:method name="get*" read-only="true" /> <tx:method name="find*" read-only="true" /> <tx:method name="select*" read-only="true" /> <!--其他方法使用默认事务策略 --> <tx:method name="*" rollback-for="Throwable"/> </tx:attributes> </tx:advice> <aop:config> <aop:pointcut id="myPointcut" expression="execution(* com.maizhe..service.*.*(..))" /> <!--将定义好的事务处理策略应用到上述的切入点 --> <aop:advisor advice-ref="txAdvice" pointcut-ref="myPointcut" /> </aop:config> </beans>
第八步：配置视图解析器，名字为maizhe-manage-servlet.xml，在web.xml文件上有配置。可以自己命名。
<?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" 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-4.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd"> <!-- 注解驱动 --> <mvc:annotation-driven/> <!-- 描述conctroller --> <context:component-scan base-package="com.maizhe.controller"/> <!-- 视图解释器 --> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <!-- 前缀 --> <property name="prefix" value="/WEB-INF/views/"/> <!-- 后缀 --> <property name="suffix" value=".jsp"/> </bean> <!-- 定义图片解释器 --> <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver"> <!-- 设置默认编码 --> <property name="defaultEncoding" value="utf-8"></property> <!-- 上传图片最大大小5M--> <property name="maxUploadSize" value="5242440"></property> </bean> </beans>
经过上面的配置之后，我们再进行测试，测试的时候dao接口继承Mapper通用接口就可以用它所有的通用方法了，不需要dao层实现类，因为我们已经在xml映射文件上实现了该方法。dao层只写我们的一些特殊的方法就可以了。
