前面一篇有說道如何在MyEclipse中搭建maven項目，這里將繼續介紹如何在搭建好的基礎maven項目中引入我們常用的javaweb框架――SpringMVC！

①在建立好的maven項目中的pom.xml文件引入依賴，代碼如下：

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>wechat.cuiyongzhi.com</groupId> <artifactId>wechat</artifactId> <packaging>war</packaging> <version>0.0.1-SNAPSHOT</version> <name>wechat</name> <url>http://maven.apache.org</url> <dependencies>  <!-- spring -->  <dependency>   <groupId>org.springframework</groupId>   <artifactId>spring-test</artifactId>   <version>3.2.0.RELEASE</version>  </dependency>  <dependency>   <groupId>org.springframework</groupId>   <artifactId>spring-webmvc</artifactId>   <version>3.2.0.RELEASE</version>  </dependency>  <dependency>   <groupId>org.springframework</groupId>   <artifactId>spring-core</artifactId>   <version>3.2.0.RELEASE</version>  </dependency>   <!-- mybatis -->  <dependency>   <groupId>org.mybatis</groupId>   <artifactId>mybatis</artifactId>   <version>3.1.1</version>  </dependency>  <dependency>   <groupId>org.mybatis</groupId>   <artifactId>mybatis-spring</artifactId>   <version>1.1.1</version>  </dependency>   <!-- mysql -->  <dependency>   <groupId>mysql</groupId>   <artifactId>mysql-connector-java</artifactId>   <version>5.1.21</version>  </dependency>   <!-- junit測試 -->  <dependency>   <groupId>junit</groupId>   <artifactId>junit</artifactId>   <version>4.11</version>   <scope>test</scope>  </dependency>   <!-- mysql阿里連接池druid -->  <dependency>   <groupId>com.alibaba</groupId>   <artifactId>druid</artifactId>   <version>0.2.9</version>  </dependency>   <!-- spring aop包 -->  <dependency>   <groupId>org.aspectj</groupId>   <artifactId>aspectjweaver</artifactId>   <version>1.7.1</version>  </dependency>   <!-- json包 -->  <dependency>   <groupId>com.alibaba</groupId>   <artifactId>fastjson</artifactId>   <version>1.2.7</version>  </dependency>   <!-- 文件上傳包 -->  <dependency>   <groupId>commons-fileupload</groupId>   <artifactId>commons-fileupload</artifactId>   <version>1.2.2</version>  </dependency>   <!--servlet包 -->  <dependency>   <groupId>javax.servlet</groupId>   <artifactId>servlet-api</artifactId>   <version>3.0-alpha-1</version>  </dependency>   <dependency>   <groupId>javax.servlet.jsp</groupId>   <artifactId>jsp-api</artifactId>   <version>2.1</version>   <scope>provided</scope>  </dependency>   <dependency>   <groupId>javax.servlet</groupId>   <artifactId>jstl</artifactId>   <version>1.2</version>  </dependency>   <!-- 日志包 -->  <dependency>   <groupId>log4j</groupId>   <artifactId>log4j</artifactId>   <version>1.2.17</version>  </dependency> </dependencies> <build>  <finalName>wechat</finalName> </build></project>

②修改項目路徑下的web.xml文件如下：

<?xml version="1.0" encoding="UTF-8"?><web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:web="http://java.sun.com/xml/ns/javaee" xmlns="http://java.sun.com/xml/ns/javaee"

③添加數據庫配置信息，這里項目配置的數據庫為MySQL，在 resources下新建config.properties配置文件，設置如下：

validationQuery=SELECT 1jdbc_url=jdbc:mysql://127.0.0.1:3306/wechat?useUnicode=true&characterEncoding=UTF-8&zeroDateTimeBehavior=convertToNulljdbc_username=root jdbc_password=123456789

④在 resources下新建spring.xml配置文件，設置如下：

<?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:context="http://www.springframework.org/schema/context" xsi:schemaLocation="http://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans-3.0.xsdhttp://www.springframework.org/schema/contexthttp://www.springframework.org/schema/context/spring-context-3.0.xsd"> <!-- 引入屬性文件 --> <context:property-placeholder location="classpath:config.properties" /> <!-- 自動掃描(自動注入) --> <context:component-scan base-package="com.cuiyongzhi.web.service" /> <context:component-scan base-package="com.cuiyongzhi.wechat.*" />   </beans>

⑤在 resources下新建spring-mvc.xml配置文件，設置如下：

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans" xmlns:mvc="http://www.springframework.org/schema/mvc" 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" 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/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd">  <!-- 自動掃描controller包下的所有類，使其認為spring mvc的控制器 --> <context:component-scan base-package="com.cuiyongzhi.web.controller" />  <!-- 避免IE執行AJAX時,返回JSON出現下載文件 --> <bean id="mappingJacksonHttpMessageConverter" class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter">  <property name="supportedMediaTypes">   <list>    <value>text/html;charset=UTF-8</value>   </list>  </property> </bean>  <!-- 啟動Spring MVC的注解功能，完成請求和注解POJO的映射 --> <bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">  <property name="messageConverters">   <list>    <ref bean="mappingJacksonHttpMessageConverter" /><!-- json轉換器 -->   </list>  </property> </bean>  <!-- 對模型視圖名稱的解析，即在模型視圖名稱添加前后綴 --> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver" p:prefix="/WEB-INF/views/" p:suffix=".jsp" />  <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">  <property name="defaultEncoding">   <value>UTF-8</value>  </property>  <property name="maxUploadSize">   <value>32505856</value><!-- 上傳文件大小限制為31M，31*1024*1024 -->  </property>  <property name="maxInMemorySize">   <value>4096</value>  </property> </bean>  </beans>

⑥在 resources下新建spring-mybatis.xml配置文件，設置如下：

<?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:tx="http://www.springframework.org/schema/tx" xmlns:aop="http://www.springframework.org/schema/aop" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsdhttp://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd">  <!-- 配置數據源 --> <bean name="dataSource" class="com.alibaba.druid.pool.DruidDataSource" init-method="init" destroy-method="close">  <property name="url" value="${jdbc_url}" />  <property name="username" value="${jdbc_username}" />  <property name="password" value="${jdbc_password}" />   <!-- 初始化連接大小 -->  <property name="initialSize" value="5" />  <!-- 連接池最大使用連接數量 -->  <property name="maxActive" value="100" />  <!-- 連接池最大空閑 -->  <property name="maxIdle" value="10" />  <!-- 連接池最小空閑 -->  <property name="minIdle" value="0" />  <!-- 獲取連接最大等待時間 -->  <property name="maxWait" value="60000" />   <property name="poolPreparedStatements" value="true" />  <property name="maxPoolPreparedStatementPerConnectionSize" value="33" />    <property name="validationQuery" value="${validationQuery}" />  <property name="testOnBorrow" value="false" />  <property name="testOnReturn" value="false" />  <property name="testWhileIdle" value="true" />   <!-- 配置間隔多久才進行一次檢測，檢測需要關閉的空閑連接，單位是毫秒 -->  <property name="timeBetweenEvictionRunsMillis" value="60000" />  <!-- 配置一個連接在池中最小生存的時間，單位是毫秒 -->  <property name="minEvictableIdleTimeMillis" value="25200000" />   <!-- 打開removeAbandoned功能 -->  <property name="removeAbandoned" value="true" />  <!-- 1800秒，也就是30分鐘 -->  <property name="removeAbandonedTimeout" value="1800" />  <!-- 關閉abanded連接時輸出錯誤日志 -->  <property name="logAbandoned" value="true" />   <!-- 監控數據庫 -->  <!-- <property name="filters" value="stat" /> -->  <property name="filters" value="mergeStat" /> </bean>  <!-- myBatis文件 --> <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">  <property name="dataSource" ref="dataSource" />  <!-- 自動掃描entity目錄, 省掉Configuration.xml里的手工配置 -->  <property name="mapperLocations" value="classpath:com/cuiyongzhi/web/mapping/*.xml" /> </bean>  <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">  <property name="basePackage" value="com.cuiyongzhi.web.dao" />  <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory" /> </bean>  <!-- 配置事務管理器 --> <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">  <property name="dataSource" ref="dataSource" /> </bean>  <!-- 注解方式配置事物 --> <!-- <tx:annotation-driven transaction-manager="transactionManager" /> -->  <!-- 攔截器方式配置事物 --> <tx:advice id="transactionAdvice" transaction-manager="transactionManager">  <tx:attributes>   <tx:method name="add*" propagation="REQUIRED" />   <tx:method name="append*" propagation="REQUIRED" />   <tx:method name="insert*" propagation="REQUIRED" />   <tx:method name="save*" propagation="REQUIRED" />   <tx:method name="update*" propagation="REQUIRED" />   <tx:method name="modify*" propagation="REQUIRED" />   <tx:method name="edit*" propagation="REQUIRED" />   <tx:method name="delete*" propagation="REQUIRED" />   <tx:method name="remove*" propagation="REQUIRED" />   <tx:method name="repair" propagation="REQUIRED" />   <tx:method name="delAndRepair" propagation="REQUIRED" />   <tx:method name="get*" propagation="SUPPORTS" />   <tx:method name="find*" propagation="SUPPORTS" />   <tx:method name="load*" propagation="SUPPORTS" />   <tx:method name="search*" propagation="SUPPORTS" />   <tx:method name="datagrid*" propagation="SUPPORTS" />   <tx:method name="*" propagation="SUPPORTS" />  </tx:attributes> </tx:advice> <aop:config>  <aop:pointcut id="transactionPointcut" expression="execution(* com.cuiyongzhi.web.service..*Impl.*(..))" />  <aop:advisor pointcut-ref="transactionPointcut" advice-ref="transactionAdvice" /> </aop:config>   <!-- 配置druid監控spring jdbc --> <bean id="druid-stat-interceptor" class="com.alibaba.druid.support.spring.stat.DruidStatInterceptor"> </bean> <bean id="druid-stat-pointcut" class="org.springframework.aop.support.JdkRegexpMethodPointcut" scope="prototype">  <property name="patterns">   <list>    <value>com.cuiyongzhi.web.service.*</value>   </list>  </property> </bean> <aop:config>  <aop:advisor advice-ref="druid-stat-interceptor" pointcut-ref="druid-stat-pointcut" /> </aop:config> </beans>

⑦在 resources下新建log4j.properties配置文件，用于日志的輸出等級以及輸出位置設置，設置如下：
