这篇文章主要讲解了“SSM如何搭建项目”，文中的讲解内容简单清晰，易于学习与理解，下面请大家跟着小编的思路慢慢深入，一起来研究和学习“SSM如何搭建项目”吧！

1.新建一个Maven工程

(1)为什么要用Maven搭建项目?

Maven可以对项目依赖的jar包进行管理，需要的jar包只需要到Maven仓库里面去拿到版本信息复制到pom.xml文件即可。同时，它也能对项目进行编译、测试、打包等功能。

(2)新建一个Maven工程(这里用的是Eclipse)：

点击File -> New Project -> Maven Project，点击Next;

弹出一个界面，这里直接点击Next，然后选择webapp那一栏，点击Next;

此时，将进入另一个界面，会叫你输入一些有关项目的信息。主要的分别是：

Group Id: 这个可以看做项目的坐标，一般为域和公司名组成

Artifact Id: 这个可以看做成项目名

Version: 这个是项目版本

点击Finish后，一个Maven项目就创建完成。此时，需要注意的是这个Maven项目可能用的是JDK1.5，这可能导致项目的目录不正确，解决办法就是：右键项目 -> 选择Properties -> 选择Java Build Path -> 选择Libraries那一栏 -> 选择JRE Library那一栏 -> Edit -> 把默认的JDK版本换成自己下载的版本即可。

2.进行Spring和SpringMVC还有Mybatis的整合

(1)首先需要依赖整合SSM相关的jar包

 <properties>     <spring.version>4.3.7.RELEASE</spring.version>
 </properties>
 <dependencies>     <!-- 测试所需要的包 -->

3.整理XML配置文件

这里我分为三个XML配置文件，一个是spring-dao(数据库的配置以及DAO层的扫描)，第二个是spring-service(扫描Service层以及事务的配置)，第三个是spring-web(扫描controller层和配置文件视图等)

(1)配置spring-dao.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"
    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">   
    <!-- 配置相关的properties过程 -->
    <context:property-placeholder location="classpath:jdbc.properties"/>
    <!-- 配置数据库连接池 -->
    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
        <!-- 配置连接池属性 -->
        <property name="driverClass" value="${jdbc.driver}" />
        <property name="jdbcUrl" value="${jdbc.url}" />
        <property name="user" value="${jdbc.username}" />
        <property name="password" value="${jdbc.password}" />

        <!-- c3p0连接池的私有属性 -->
        <property name="maxPoolSize" value="30" />
        <property name="minPoolSize" value="10" />
        <!-- 关闭连接后不自动commit -->
        <property name="autoCommitOnClose" value="false" />
        <!-- 获取连接超时时间 -->
        <property name="checkoutTimeout" value="10000" />
        <!-- 当获取连接失败重试次数 -->
        <property name="acquireRetryAttempts" value="2" />
    </bean>
    <!-- 配置连sqlSessionFactory对象 -->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <!-- 注入数据库连接池 -->
        <property name="dataSource" ref="dataSource" />
        <!-- 配置MyBaties全局配置文件:mybatis-config.xml -->
        <property name="configLocation" value="classpath:mybatis-config.xml" />
        <!-- 扫描entity包 使用别名 -->
        <property name="typeAliasesPackage" value="com.yangxiang.pojo" />
        <!-- 扫描sql配置文件:mapper需要的xml文件 -->
        <property name="mapperLocations" value="classpath:mapper/*.xml" />
    </bean>
    <!-- 配置DAO接口包 -->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <!-- 注入sqlSessionFactory -->
        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory" />
        <!-- 给出需要扫描Dao接口包 -->
        <property name="basePackage" value="com.yangxiang.dao" />
    </bean>        </beans>

其中spring-dao引用了定义的jdbc.properties和mybatis-config.xml

jdbc.properties内容如下：

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/course?useUnicode=true&characterEncoding=utf8
jdbc.username=root
jdbc.password=password

mybatis-config.xml内容如下：

<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE configuration PUBLIC   
    "-//mybatis.org//DTD Mapper 3.0//EN"  
    "http://mybatis.org/dtd/mybatis-3-config.dtd"><configuration>
    <!-- 配置全局屬性 -->
    <settings>
        <!-- 是否使用主键生成 -->
        <setting name="useGeneratedKeys" value="true" />
        <!-- 别名比列标签有限 -->
        <setting name="useColumnLabel" value="true"/>
        <!-- 是否使用下划线与驼峰命名转换 -->
        <setting name="mapUnderscoreToCamelCase" value="true" />
    </settings></configuration>

配置spring-service.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: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/tx
    http://www.springframework.org/schema/tx/spring-tx.xsd">    
    <!-- 扫描service包下所有使用注解的类型 -->
    <context:component-scan base-package="com.yangxiang.service" />    
     <!-- 配置事务管理器 -->
    <bean id="transactionManager"
        class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <!-- 注入数据库连接池 -->
        <property name="dataSource" ref="dataSource" />
    </bean>
    <!-- 配置基于注解的声明式事务 -->
    <tx:annotation-driven transaction-manager="transactionManager" />  </beans>

配置spring-web.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"
    xmlns:aop="http://www.springframework.org/schema/aop"
    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-3.2.xsd   
    http://www.springframework.org/schema/aop 
    http://www.springframework.org/schema/aop/spring-aop-3.0.xsd">
    <!-- 配置SpringMVC -->
    <!-- 1.开启SpringMVC注解模式 -->
    <mvc:annotation-driven />
    <context:component-scan
        base-package="com.yangxiang.web" />
    <!-- 定义静态资源的处理 -->
    <!-- 2.静态资源默认servlet配置 (1)加入对静态资源的处理：js,gif,png (2)允许使用"/"做整体映射 -->
    <mvc:resources mapping="/resources/**"
        location="/resources/" />
    <mvc:default-servlet-handler />
    <!-- 定义视图解析器 -->
    <bean id="viewResolver"
        class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/html/"></property>
        <property name="suffix" value=".html"></property>
    </bean>
    <!-- 文件上传解析器 -->
    <bean id="multipartResolver"
        class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
        <property name="defaultEncoding" value="utf-8"></property>
        <property name="maxUploadSize" value="10485760000"></property><!-- 最大上传文件大小 -->
        <property name="maxInMemorySize" value="10960"></property>
    </bean>
    <!-- 在spring-mvc.xml文件中加入这段配置后，spring返回给页面的都是utf-8编码了 -->
    <bean
        class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
        <property name="messageConverters">
            <list>
                <bean
                    class="org.springframework.http.converter.StringHttpMessageConverter">
                    <property name="supportedMediaTypes">
                        <list>
                            <value>text/html;charset=UTF-8</value>
                        </list>
                    </property>
                </bean>
            </list>
        </property>
    </bean></beans>

在上面把SSM的配置写完后，需要在web.xml引入

<!DOCTYPE web-app PUBLIC
 "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
 "http://java.sun.com/dtd/web-app_2_3.dtd" ><web-app>
    <display-name>Archetype Created Web Application</display-name>    
    <!-- 设置UTF-8格式 -->
    <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>
    </filter>
    <filter-mapping>
        <filter-name>characterEncoding</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>
    <!-- 配置SpringMVC核心拦截器 -->
    <servlet>
        <servlet-name>springmvc</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <!-- 初始化spring-dao,spring-service,spring-web配置文件 -->
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:spring/spring-*.xml</param-value>
        </init-param>
    </servlet>
    <servlet-mapping>
        <servlet-name>springmvc</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping></web-app>

当完成以上配置后，就可以开始写代码了。
