eclipse下利用maven搭建ssm环境

自己搭建了好几天终于把框架搭好了，被吐槽搭的太慢了，网上的大神写的博文太骚气了，作为第一次接触框架的我实在看的有点晕，写这篇博客记录下搭建的步骤，也为了让以后搭建框架的兄弟少踩一点坑吧

1、创建maven项目

具体创建步骤可以参考eclipse下利用maven创建项目，创建好的项目整体目录结构如图所示

2、配置pom.xml

（1）引入依赖，spring、mybatis、servlet、jsp相关、poi、pageHelper、io等

<!-- 统一定义jar包版本号 -->  <properties>

<groupId>org.springframework</groupId>            <artifactId>spring-test</artifactId>            <version>${spring.version}</version>        </dependency> </dependencies>

（2）配置Tomcat插件、字符编码过滤，注意build节点下resources结点的配置，以防mybatis的mapper.xml文件被漏掉

<build>          <plugins>  <!-- Tomcat插件 -->  <plugin>  <groupId>org.apache.tomcat.maven</groupId><artifactId>tomcat7-maven-plugin</artifactId><version>2.2</version><configuration><port>8181</port><path>/ebookshop</path></configuration>  </plugin>    <plugin>     <groupId>org.apache.maven.plugins</groupId>      <artifactId>maven-compiler-plugin</artifactId>      <version>3.1</version>      <configuration>          <verbose>true</verbose>          <fork>true</fork>          <executable>C:\Program Files\Java\jdk1.8.0_141\bin\javac</executable>        <webappDirectory>${basedir}/src/main/webapp</webappDirectory><warSourceDirectory>${basedir}/src/main/webapp</warSourceDirectory>      </configuration>  </plugin>   </plugins>  <resources>  <!-- 如果不添加此节点mybatis的mapper.xml文件都会被漏掉。 --><resource><directory>src/main/java</directory><includes><include>**/mapper/*.properties</include><include>**/mapper/*.xml</include></includes><filtering>false</filtering></resource><resource><directory>src/main/resources</directory><includes><include>*.properties</include><include>*.xml</include></includes><filtering>false</filtering></resource></resources>       <!-- 项目名 -->      <finalName>ebookshop</finalName>        </build>  

3、整合spring mvc

（1）配置spring-mvc.xml，此文件放在src/main/resources文件夹下

<?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-4.0.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-4.0.xsd">         <!-- 注解扫描 表现层（控制器层） --> <!-- mvc也是一个容器，是spring的子容器，可以访问父容器spring中的对象，一般用来层创建controller层的对象 --><!-- 使用Annotation自动注册Bean,只扫描@Controller --><context:component-scan base-package="com.sliver.ebookshop.controller" use-default-filters="false"><!-- base-package 如果多个，用“,”分隔 --><context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/></context:component-scan><mvc:annotation-driven /><!-- 配置视图解析器 前/后缀 --><bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"><property name="prefix" value="/WEB-INF/jsp/" /><property name="suffix" value=".jsp" /></bean><!-- 定义文件上传解析器 --><bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver"><!-- 设定默认编码 --><property name="defaultEncoding" value="UTF-8"></property><!-- 设定文件上传的最大值5MB，5*1024*1024 --><property name="maxUploadSize" value="5242880"></property><property name="maxInMemorySize" value="4096" /></bean><!-- 资源映射，防止静态资源被转发 --><mvc:resources mapping="/css/**" location="/css/" /><mvc:resources mapping="/js/**" location="/js/"/><mvc:resources mapping="/fonts/**" location="/fonts/"/></beans>       

（2）配置web.xml，指定spring-mvc.xml所在位置

    <!-- Spring MVC servlet -->        <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:spring-mvc.xml</param-value>            </init-param>            <load-on-startup>1</load-on-startup>            <!-- <async-supported>true</async-supported>  -->     </servlet>        <servlet-mapping>            <servlet-name>SpringMVC</servlet-name>            <url-pattern>*.do</url-pattern>        </servlet-mapping>    

4、整合mybatis

（1）配置jdbc.properties，指定连接数据库的一些属性，url后写明连接的数据库，username填写数据库用户名，password填写密码

dbcp.driver=com.mysql.jdbc.Driverdbcp.url=jdbc:mysql://127.0.0.1:3306/ebookshop?useUnicode=true&characterEncoding=utf8dbcp.username=rootdbcp.password=passworddbcp.maxActive=10dbcp.minIdle=5dbcp.maxWait=50000

（2）配置applicationContext，此文件放在src/main/resources文件夹下，指定扫描mapper以及service所在的位置

<?xml version="1.0" encoding="UTF-8"?><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.xsdhttp://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsdhttp://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.xsdhttp://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-4.0.xsd">   <!-- 导入外部的properties配置文件 -->  <context:property-placeholder location="classpath:jdbc.properties" /><!-- 配置dbcp数据源 -->           <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">          <property name="driverClassName" value="${dbcp.driver}" />          <property name="url" value="${dbcp.url}" />          <property name="username" value="${dbcp.username}" />          <property name="password" value="${dbcp.password}" />          <property name="maxActive" value="${dbcp.maxActive}"/>         <property name="minIdle" value="${dbcp.minIdle}"/>          <property name="maxWait" value="${dbcp.maxWait}"/>      </bean>      <!-- 配置SqlSessionFactoryBean，目的：加载mybaits配置文件和映射文件，即替代原Mybatis工具类的作用 -->   <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">   <property name="dataSource" ref="dataSource"/>   <!-- 给映射的类配置别名-->          <!-- <property name="typeAliasesPackage" value="cn.edu.njit.zc.pojo"/> -->   <!-- 配置分页查询PageHelper插件配置 -->   <property name="plugins">            <array>                <bean class="com.github.pagehelper.PageHelper">                    <property name="properties">                        <value>dialect=mysql</value>                    </property>                </bean>            </array>        </property> </bean>  <!-- dao接口所在包名，Spring会自动查找其下的类 -->      <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">    <!-- 多个包，以','隔开 -->        <property name="basePackage" value="com.sliver.ebookshop.mapper" />          <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property>      </bean>        <!-- 配置Mybatis的事务管理器，即因为Mybatis底层用的是JDBC事务管事器，所以在这里依然配置JDBC事务管理器 -->    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">   <property name="dataSource" ref="dataSource"/>    </bean>    <!-- 配置事务通知，即让哪些方法需要事务支持 -->    <tx:advice id="txAdvice" transaction-manager="transactionManager"><tx:attributes><!-- 传播行为 --><tx:method name="save*" propagation="REQUIRED" rollback-for="Exception"/><tx:method name="insert*" propagation="REQUIRED" /><tx:method name="add*" propagation="REQUIRED" /><tx:method name="create*" propagation="REQUIRED" /><tx:method name="delete*" propagation="REQUIRED" /><tx:method name="update*" propagation="REQUIRED" /><tx:method name="find*" propagation="SUPPORTS" read-only="true" /><tx:method name="select*" propagation="SUPPORTS" read-only="true" /><tx:method name="get*" propagation="SUPPORTS" read-only="true" /></tx:attributes></tx:advice>         <!-- 配置事务切面，aop配置被事务控制的类,即让哪些包下的类需要事务 -->        <aop:config>  <aop:pointcut id="pt" expression="bean(*Service)"/><!-- 扫描以Service结尾的bean -->  <aop:advisor advice-ref="txAdvice" pointcut-ref="pt"/>   </aop:config>      <!-- 扫描service实现层 多个包，以','隔开-->   <context:component-scan base-package="com.sliver.ebookshop.service"></context:component-scan></beans>      

（3）配置web.xml

    <!-- 加载spring bean -->        <context-param>            <param-name>contextConfigLocation</param-name>            <param-value>classpath:applicationContext.xml</param-value>        </context-param>        <listener>            <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>        </listener>    

至此，ssm环境已经搭建完毕，回顾一下做了哪些配置

1、maven的pom.xml文件中配置引入依赖的jar包，并添加tomcat插件（tomcat插件不配置也可以，就是每次都要通过tomcat启动，大家根据自己是否方便来吧）

2、配置spring-mvc，指明控制层扫描的包所在的位置，配置视图解析器（视图解析器的作用主要是当控制层做页面跳转的时候不需要再指明跳转的jsp文件所在位置，同时跳转时会自动去查找后缀名为.jsp的文件）

3、配置jdbc.properties，指明连接的数据库、用户名、密码等等

4、配置applicationContext.xml，引入jdbc.properties中对数据库的配置，指明mybatis扫描的映射以及service所在的位置

5、配置web.xml，指明spring和mybatis配置文件所在位置，即spring-mvc.xml和applicationContext.xml所在的位置
